Version 3, 29 June 2007
Copyright (C) 2007 Free Software Foundation, Inc.
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.
TERMS AND CONDITIONS
0. Definitions.
"This License" refers to version 3 of the GNU General Public License.
"Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
"The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.
To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
A "covered work" means either the unmodified Program or a work based
on the Program.
To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
Copyright (C)
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see .
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
Copyright (C)
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
.
The GNU General Public License does not permit incorporating your program

readline-7.0/README 000664 000436 000024 00000017534 12545254534 014131 0 ustar 00chet staff 000000 000000 Introduction
============
This is the Gnu Readline library, version 7.0.
The Readline library provides a set of functions for use by applications
that allow users to edit command lines as they are typed in. Both
Emacs and vi editing modes are available. The Readline library includes
additional functions to maintain a list of previously-entered command
lines, to recall and perhaps reedit those lines, and perform csh-like
history expansion on previous commands.
The history facilites are also placed into a separate library, the
History library, as part of the build process. The History library
may be used without Readline in applications which desire its
capabilities.
The Readline library is free software, distributed under the terms of
the [GNU] General Public License as published by the Free Software
Foundation, version 3 of the License. For more information, see the
file COPYING.
To build the library, try typing `./configure', then `make'. The
configuration process is automated, so no further intervention should
be necessary. Readline builds with `gcc' by default if it is
available. If you want to use `cc' instead, type
CC=cc ./configure
if you are using a Bourne-style shell. If you are not, the following
may work:
env CC=cc ./configure
Read the file INSTALL in this directory for more information about how
to customize and control the build process.
The file rlconf.h contains C preprocessor defines that enable and disable
certain Readline features.
The special make target `everything' will build the static and shared
libraries (if the target platform supports them) and the examples.
Examples
========
There are several example programs that use Readline features in the
examples directory. The `rl' program is of particular interest. It
is a command-line interface to Readline, suitable for use in shell
scripts in place of `read'.
Shared Libraries
================
There is skeletal support for building shared versions of the
Readline and History libraries. The configure script creates
a Makefile in the `shlib' subdirectory, and typing `make shared'
will cause shared versions of the Readline and History libraries
to be built on supported platforms.
If `configure' is given the `--enable-shared' option, it will attempt
to build the shared libraries by default on supported platforms.
Configure calls the script support/shobj-conf to test whether or
not shared library creation is supported and to generate the values
of variables that are substituted into shlib/Makefile. If you
try to build shared libraries on an unsupported platform, `make'
will display a message asking you to update support/shobj-conf for
your platform.
If you need to update support/shobj-conf, you will need to create
a `stanza' for your operating system and compiler. The script uses
the value of host_os and ${CC} as determined by configure. For
instance, FreeBSD 4.2 with any version of gcc is identified as
`freebsd4.2-gcc*'.
In the stanza for your operating system-compiler pair, you will need to
define several variables. They are:
SHOBJ_CC The C compiler used to compile source files into shareable
object files. This is normally set to the value of ${CC}
by configure, and should not need to be changed.
SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create
position-independent code. If you are using gcc, this
should probably be set to `-fpic'.
SHOBJ_LD The link editor to be used to create the shared library from
the object files created by $SHOBJ_CC. If you are using
gcc, a value of `gcc' will probably work.
SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation.
If you are using gcc, `-shared' may be all that is necessary.
These should be the flags needed for generic shared object
creation.
SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library
creation. Many systems use the -R option to the link
editor to embed a path within the library for run-time
library searches. A reasonable value for such systems would
be `-R$(libdir)'.
SHLIB_LIBS Any additional libraries that shared libraries should be
linked against when they are created.
SHLIB_LIBPREF The prefix to use when generating the filename of the shared
library. The default is `lib'; Cygwin uses `cyg'.
SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when
generating the filename of the shared library. Many systems
use `so'; HP-UX uses `sl'.
SHLIB_LIBVERSION The string to append to the filename to indicate the version
of the shared library. It should begin with $(SHLIB_LIBSUFF),
and possibly include version information that allows the
run-time loader to load the version of the shared library
appropriate for a particular program. Systems using shared
libraries similar to SunOS 4.x use major and minor library
version numbers; for those systems a value of
`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
Systems based on System V Release 4 don't use minor version
numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
Other Unix versions use different schemes.
SHLIB_DLLVERSION The version number for shared libraries that determines API
compatibility between readline versions and the underlying
system. Used only on Cygwin. Defaults to $SHLIB_MAJOR, but
can be overridden at configuration time by defining DLLVERSION
in the environment.
SHLIB_DOT The character used to separate the name of the shared library
from the suffix and version information. The default is `.';
systems like Cygwin which don't separate version information
from the library name should set this to the empty string.
SHLIB_STATUS Set this to `supported' when you have defined the other
necessary variables. Make uses this to determine whether
or not shared library creation should be attempted.
You should look at the existing stanzas in support/shobj-conf for ideas.
Once you have updated support/shobj-conf, re-run configure and type
`make shared'. The shared libraries will be created in the shlib
subdirectory.
If shared libraries are created, `make install' will install them.
You may install only the shared libraries by running `make
install-shared' from the top-level build directory. Running `make
install' in the shlib subdirectory will also work. If you don't want
to install any created shared libraries, run `make install-static'.
Documentation
=============
The documentation for the Readline and History libraries appears in
the `doc' subdirectory. There are three texinfo files and a
Unix-style manual page describing the facilities available in the
Readline library. The texinfo files include both user and
programmer's manuals. HTML versions of the manuals appear in the
`doc' subdirectory as well.
Usage
=====
Our position on the use of Readline through a shared-library linking
mechanism is that there is no legal difference between shared-library
linking and static linking--either kind of linking combines various
modules into a single larger work. The conditions for using Readline
in a larger work are stated in section 3 of the GNU GPL.
Reporting Bugs
==============
Bug reports for Readline should be sent to:
bug-readline@gnu.org
When reporting a bug, please include the following information:
* the version number and release status of Readline (e.g., 4.2-release)
* the machine and OS that it is running on
* a list of the compilation flags or the contents of `config.h', if
appropriate
* a description of the bug
* a recipe for recreating the bug reliably
* a fix for the bug if you have one!
If you would like to contact the Readline maintainer directly, send mail
to bash-maintainers@gnu.org.
Since Readline is developed along with bash, the bug-bash@gnu.org mailing
list (mirrored to the Usenet newsgroup gnu.bash.bug) often contains
Readline bug reports and fixes.

readline-7.0/INSTALL 000664 000436 000024 00000030020 12545254551 014262 0 ustar 00chet staff 000000 000000 Basic Installation
==================
These are installation instructions for Readline-7.0.
The simplest way to compile readline is:
1. `cd' to the directory containing the readline source code and type
`./configure' to configure readline for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes some time. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile readline and build the static readline
and history libraries. If supported, the shared readline and history
libraries will be built also. See below for instructions on compiling
the other parts of the distribution. Typing `make everything' will
cause the static and shared libraries (if supported) and the example
programs to be built.
3. Type `make install' to install the static readline and history
libraries, the readline include files, the documentation, and, if
supported, the shared readline and history libraries.
4. You can remove the created libraries and object files from the
build directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile readline for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the readline developers, and should be used with care.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It
uses those values to create a `Makefile' in the build directory,
and Makefiles in the `doc', `shlib', and `examples'
subdirectories. It also creates a `config.h' file containing
system-dependent definitions. Finally, it creates a shell script
`config.status' that you can run in the future to recreate the
current configuration, a file `config.cache' that saves the
results of its tests to speed up reconfiguring, and a file
`config.log' containing compiler output (useful mainly for
debugging `configure').
If you need to do unusual things to compile readline, please try
to figure out how `configure' could check whether to do them, and
mail diffs or instructions to so they can
be considered for the next release. If at some point
`config.cache' contains results you don't want to keep, you may
remove or edit it.
The file `configure.in' is used to create `configure' by a
program called `autoconf'. You only need `configure.in' if you
want to change it or regenerate `configure' using a newer version
of `autoconf'. The readline `configure.in' requires autoconf
version 2.50 or newer.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. You can give `configure'
initial values for variables by setting them in the environment. Using
a Bourne-compatible shell, you can do that on the command line like
this:
CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
Or on systems that have the `env' program, you can do it like this:
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
Compiling For Multiple Architectures
====================================
You can compile readline for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not supports the `VPATH'
variable, you have to compile readline for one architecture at a
time in the source code directory. After you have installed
readline for one architecture, use `make distclean' before
reconfiguring for another architecture.
Installation Names
==================
By default, `make install' will install the readline libraries in
`/usr/local/lib', the include files in
`/usr/local/include/readline', the man pages in `/usr/local/man',
and the info files in `/usr/local/info'. You can specify an
installation prefix other than `/usr/local' by giving `configure'
the option `--prefix=PATH' or by supplying a value for the
DESTDIR variable when running `make install'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files.
If you give `configure' the option `--exec-prefix=PATH', the
readline Makefiles will use PATH as the prefix for installing the
libraries. Documentation and other data files will still use the
regular prefix.
Specifying the System Type
==========================
There may be some features `configure' can not figure out
automatically, but need to determine by the type of host readline
will run on. Usually `configure' can figure that out, but if it
prints a message saying it can not guess the host type, give it
the `--host=TYPE' option. TYPE can either be a short name for
the system type, such as `sun4', or a canonical name with three
fields: CPU-COMPANY-SYSTEM (e.g., i386-unknown-freebsd4.2).
See the file `config.sub' for the possible values of each field.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: the readline `configure' looks for a site script, but not
all `configure' scripts do.
Operation Controls
==================
`configure' recognizes the following options to control how it
operates.
`--cache-file=FILE'
Use and save the results of the tests in FILE instead of
`./config.cache'. Set FILE to `/dev/null' to disable caching, for
debugging `configure'.
`--help'
Print a summary of the options to `configure', and exit.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made.
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--version'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`configure' also accepts some other, not widely useful, options.
Optional Features
=================
The readline `configure' recognizes a single `--with-PACKAGE' option:
`--with-curses'
This tells readline that it can find the termcap library functions
(tgetent, et al.) in the curses library, rather than a separate
termcap library. Readline uses the termcap functions, but does not
link with the termcap or curses library itself, allowing applications
which link with readline the to choose an appropriate library.
This option tells readline to link the example programs with the
curses library rather than libtermcap.
`configure' also recognizes two `--enable-FEATURE' options:
`--enable-shared'
Build the shared libraries by default on supported platforms. The
default is `yes'.
`--enable-static'
Build the static libraries by default. The default is `yes'.
Shared Libraries
================
There is support for building shared versions of the readline and
history libraries. The configure script creates a Makefile in
the `shlib' subdirectory, and typing `make shared' will cause
shared versions of the readline and history libraries to be built
on supported platforms.
If `configure' is given the `--enable-shared' option, it will attempt
to build the shared libraries by default on supported platforms.
Configure calls the script support/shobj-conf to test whether or
not shared library creation is supported and to generate the values
of variables that are substituted into shlib/Makefile. If you
try to build shared libraries on an unsupported platform, `make'
will display a message asking you to update support/shobj-conf for
your platform.
If you need to update support/shobj-conf, you will need to create
a `stanza' for your operating system and compiler. The script uses
the value of host_os and ${CC} as determined by configure. For
instance, FreeBSD 4.2 with any version of gcc is identified as
`freebsd4.2-gcc*'.
In the stanza for your operating system-compiler pair, you will need to
define several variables. They are:
SHOBJ_CC The C compiler used to compile source files into shareable
object files. This is normally set to the value of ${CC}
by configure, and should not need to be changed.
SHOBJ_CFLAGS Flags to pass to the C compiler ($SHOBJ_CC) to create
position-independent code. If you are using gcc, this
should probably be set to `-fpic'.
SHOBJ_LD The link editor to be used to create the shared library from
the object files created by $SHOBJ_CC. If you are using
gcc, a value of `gcc' will probably work.
SHOBJ_LDFLAGS Flags to pass to SHOBJ_LD to enable shared object creation.
If you are using gcc, `-shared' may be all that is necessary.
These should be the flags needed for generic shared object
creation.
SHLIB_XLDFLAGS Additional flags to pass to SHOBJ_LD for shared library
creation. Many systems use the -R option to the link
editor to embed a path within the library for run-time
library searches. A reasonable value for such systems would
be `-R$(libdir)'.
SHLIB_LIBS Any additional libraries that shared libraries should be
linked against when they are created.
SHLIB_LIBPREF The prefix to use when generating the filename of the shared
library. The default is `lib'; Cygwin uses `cyg'.
SHLIB_LIBSUFF The suffix to add to `libreadline' and `libhistory' when
generating the filename of the shared library. Many systems
use `so'; HP-UX uses `sl'.
SHLIB_LIBVERSION The string to append to the filename to indicate the version
of the shared library. It should begin with $(SHLIB_LIBSUFF),
and possibly include version information that allows the
run-time loader to load the version of the shared library
appropriate for a particular program. Systems using shared
libraries similar to SunOS 4.x use major and minor library
version numbers; for those systems a value of
`$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)$(SHLIB_MINOR)' is appropriate.
Systems based on System V Release 4 don't use minor version
numbers; use `$(SHLIB_LIBSUFF).$(SHLIB_MAJOR)' on those systems.
Other Unix versions use different schemes.
SHLIB_DLLVERSION The version number for shared libraries that determines API
compatibility between readline versions and the underlying
system. Used only on Cygwin. Defaults to $SHLIB_MAJOR, but
can be overridden at configuration time by defining DLLVERSION
in the environment.
SHLIB_DOT The character used to separate the name of the shared library
from the suffix and version information. The default is `.';
systems like Cygwin which don't separate version information
from the library name should set this to the empty string.
SHLIB_STATUS Set this to `supported' when you have defined the other
necessary variables. Make uses this to determine whether
or not shared library creation should be attempted. If
shared libraries are not supported, this will be set to
`unsupported'.
You should look at the existing stanzas in support/shobj-conf for ideas.
Once you have updated support/shobj-conf, re-run configure and type
`make shared' or `make'. The shared libraries will be created in the
shlib subdirectory.
If shared libraries are created, `make install' will install them.
You may install only the shared libraries by running `make
install-shared' from the top-level build directory. Running `make
install' in the shlib subdirectory will also work. If you don't want
to install any created shared libraries, run `make install-static'.

- install-examples: should not depend on `shared', since the examples
themselves are not built using shared libraries. Report from
support/shobj-conf
- [from bash] darwin: changed the install_name embedded into the
shared library to contain only the major version number, not the
minor one. The idea is that the minor versions should all be API/ABI
compatible, and it is better to link automatically with the latest
one. Idea from Max Horn

readline-7.0/CHANGES 000664 000436 000024 00000200021 12757055401 014222 0 ustar 00chet staff 000000 000000 This document details the changes between this version, readline-7.0, and the
previous version, readline-6.3.
1. Changes to Readline
a. A bug that caused vi-mode `.' to be unable to redo `c', `d', and `y'
commands with modifiers was fixed.
b. Fixed a bug that caused callback mode to dump core when reading a
multiple-key sequence (e.g., arrow keys).
c. Fixed a bug that caused the redisplay code to erase some of the line when
using horizontal scrolling with incremental search.
d. Readline's input handler now performs signal processing if read(2) is
interrupted by SIGALRM or SIGVTALRM.
e. Fixed a problem with revert-all-at-newline freeing freed memory.
f. Clarified the documentation for the history_quotes_inhibit_expansion
variable to note that it inhibits scanning for the history comment
character and that it only affects double-quoted strings.
g. Fixed an off-by-one error in the prompt printed when performing searches.
h. Use pselect(2), if available, to wait for input before calling read(2), so
a SIGWINCH can interrupt it, since it doesn't interrupt read(2).
i. Some memory leaks caused by signals interrupting filename completion have
been fixed.
j. Reading EOF twice on a non-empty line causes EOF to be returned, rather
than the partial line. This can cause partial lines to be executed on
SIGHUP, for example.
k. Fixed a bug concerning deleting multibyte characters from the search
string while performing an incremental search.
l. Fixed a bug with tilde expanding directory names in filename completion.
m. Fixed a bug that did not allow binding sequences beginning with a `\'.
n. Fixed a redisplay bug involving incorrect line wrapping when the prompt
contains a multibyte character in the last screen column.
o. Fixed a bug that caused history expansion to disregard characters that are
documented to delimit a history event specifier without requiring `:'.
p. Fixed a bug that could cause reading past the end of a string when reading
the value when binding the set of isearch terminators.
q. Fixed a bug that caused readline commands that depend on knowing which
key invoked them to misbehave when dispatching key sequences that are
prefixes of other key bindings.
r. Paren matching now works in vi insert mode.
s. Colored completion prefixes are now displayed using a different color, less
likely to collide with files.
t. Fixed a bug that caused vi-mode character search to misbehave when
running in callback mode.
u. Fixed a bug that caused output to be delayed when input is coming from a
macro in vi-mode.
v. Fixed a bug that caused the vi-mode `.' command to misbehave when redoing
a multi-key key sequence via a macro.
w. Fixed a bug that caused problems with applications that supply their own
input function when performing completion.
x. When read returns -1/EIO when attempting to read a key, return an error
instead of line termination back to the caller.
y. Updated tty auditing feature based on patch from Red Hat.
z. Fixed a bug that could cause the history library to crash on overflows
introduced by malicious editing of timestamps in the history file.
aa. The history file writing functions only attempt to create and use a backup
history file if the history file exists and is a regular file.
bb. Fixed an out-of-bounds read in readline's internal tilde expansion interface.
cc. Fixed several redisplay bugs with prompt strings containing multibyte
and non-visible characters whose physical length is longer than the screen
width.
dd. Fixed a redisplay bug with prompt strings containing invisible characters
whose physical length exceeds the screen width and using incremental search.
ee. Readline prints more descriptive error messages when it encounters errors
while reading an inputrc file.
ff. Fixed a bug in the character insertion code that attempts to optimize
typeahead when it reads a character that is not bound to self-insert and
resets the key sequence state.
gg. When refreshing the line as the result of a key sequence, Readline attempts
to redraw only the last line of a multiline prompt.
hh. Fixed an issue that caused completion of git commands to display
incorrectly when using colored-completion-prefix.
ii. Fixed several redisplay bugs having to do with multibyte characters and
invisible characters in prompt strings.
jj. Fixed a bug that caused mode strings to be displayed incorrectly if the
prompt was shorter than the mode string.
2. New Features in Readline
a. The history truncation code now uses the same error recovery mechansim as
the history writing code, and restores the old version of the history file
on error. The error recovery mechanism handles symlinked history files.
b. There is a new bindable variable, `enable-bracketed-paste', which enables
support for a terminal's bracketed paste mode.
c. The editing mode indicators can now be strings and are user-settable
(new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string'
variables). Mode strings can contain invisible character sequences.
Setting mode strings to null strings restores the defaults.
d. Prompt expansion adds the mode string to the last line of a multi-line
prompt (one with embedded newlines).
e. There is a new bindable variable, `colored-completion-prefix', which, if
set, causes the common prefix of a set of possible completions to be
displayed in color.
f. There is a new bindable command `vi-yank-pop', a vi-mode version of emacs-
mode yank-pop.
g. The redisplay code underwent several efficiency improvements for multibyte
locales.
h. The insert-char function attempts to batch-insert all pending typeahead
that maps to self-insert, as long as it is coming from the terminal.
i. rl_callback_sigcleanup: a new application function that can clean up and
unset any state set by readline's callback mode. Intended to be used
after a signal.
j. If an incremental search string has its last character removed with DEL, the
resulting empty search string no longer matches the previous line.
k. If readline reads a history file that begins with `#' (or the value of
the history comment character) and has enabled history timestamps, the history
entries are assumed to be delimited by timestamps. This allows multi-line
history entries.
l. Readline now throws an error if it parses a key binding without a terminating
`:' or whitespace.
m. The default binding for ^W in vi mode now uses word boundaries specified
by Posix (vi-unix-word-rubout is bindable command name).
n. rl_clear_visible_line: new application-callable function; clears all
screen lines occupied by the current visible readline line.
o. rl_tty_set_echoing: application-callable function that controls whether
or not readline thinks it is echoing terminal output.
p. Handle >| and strings of digits preceding and following redirection
specifications as single tokens when tokenizing the line for history
expansion.
q. Fixed a bug with displaying completions when the prefix display length
is greater than the length of the completions to be displayed.
r. The :p history modifier now applies to the entire line, so any expansion
specifying :p causes the line to be printed instead of expanded.
s. New application-callable function: rl_pending_signal(): returns the signal
number of any signal readline has caught but not yet handled.
t. New application-settable variable: rl_persistent_signal_handlers: if set
to a non-zero value, readline will enable the readline-6.2 signal handler
behavior in callback mode: handlers are installed when
rl_callback_handler_install is called and removed removed when a complete
line has been read.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-6.3, and the
previous version, readline-6.2.
1. Changes to Readline
a. Fixed a bug that did not allow the `dd', `cc', or `yy' vi editing mode
commands to work on the entire line.
b. Fixed a bug that caused redisplay problems with prompts longer than 128
characters and history searches.
c. Fixed a bug that caused readline to try and run code to modify its idea
of the screen size in a signal handler context upon receiving a SIGWINCH.
d. Fixed a bug that caused the `meta' key to be enabled beyond the duration
of an individual call top readline().
e. Added a workaround for a wcwidth bug in Mac OS X that caused readline's
redisplay to mishandle zero-width combining characters.
f. Fixed a bug that caused readline to `forget' part of a key sequence when
a multiple-key sequence caused it to break out of an incremental search.
g. Fixed bugs that caused readline to execute code in a signal handler
context if interrupted while reading from the file system during completion.
h. Fixed a bug that caused readline to `forget' part of a key sequence when
reading an unbound multi-character key sequence.
i. Fixed a bug that caused Readline's signal handlers to be installed beyond
the bounds of a single call to readline().
j. Fixed a bug that caused the `.' command to not redo the most recent `R'
command in vi mode.
k. Fixed a bug that caused ignoring case in completion matches to result in
readline using the wrong match.
l. Paren matching now works in vi insert mode.
m. Fix menu-completion to make show-all-if-ambiguous and menu-complete-display-prefix
work together.
n. Fixed a bug that didn't allow the `cc', `dd', or `yy' commands to be redone
in vi editing mode.
o. Fixed a bug that caused the filename comparison code to not compare
multibyte characters correctly when using case-sensitive or case-mapping
comparisons.
p. Fixed the input reading loop to call the input hook function only when there
is no terminal input available.
q. Fixed a bug that caused binding a macro to a multi-character key sequence
where the sequence and macro value share a common prefix to not perform
the macro replacement.
r. Fixed several redisplay errors with multibyte characters and prompts
containing invisible characters when using horizontal scrolling.
s. Fixed a bug that caused redisplay errors when trying to overwrite
existing characters using multibyte characters.
t. Fixed a bug in vi mode that caused the arrow keys to set the saved last
vi-mode command to the wrong value.
u. Fixed a bug that caused double-quoted strings to be scanned incorrectly
when being used as the value of a readline variable assignment.
v. Fixed a bug with vi mode that prevented `.' from repeating a command
entered on a previous line (command).
w. Fixed a bug that could cause completion to core dump if it was interrupted
by a signal.
x. Fixed a bug that could cause readline to crash and seg fault attempting to
expand an empty history entry.
y. Fixed a bug that caused display problems with multi-line prompts containing
invisible characters on multiple lines.
z. Fixed a bug that caused effects made by undoing changes to a history line to
be discarded.
2. New Features in Readline
a. Readline is now more responsive to SIGHUP and other fatal signals when
reading input from the terminal or performing word completion but no
longer attempts to run any not-allowable functions from a signal handler
context.
b. There are new bindable commands to search the history for the string of
characters between the beginning of the line and the point
(history-substring-search-forward, history-substring-search-backward)
c. Readline allows quoted strings as the values of variables when setting
them with `set'. As a side effect, trailing spaces and tabs are ignored
when setting a string variable's value.
d. The history library creates a backup of the history file when writing it
and restores the backup on a write error.
e. New application-settable variable: rl_filename_stat_hook: a function called
with a filename before using it in a call to stat(2). Bash uses it to
expand shell variables so things like $HOME/Downloads have a slash
appended.
f. New bindable function `print-last-kbd-macro', prints the most-recently-
defined keyboard macro in a reusable format.
g. New user-settable variable `colored-stats', enables use of colored text
to denote file types when displaying possible completions (colored analog
of visible-stats).
h. New user-settable variable `keyseq-timout', acts as an inter-character
timeout when reading input or incremental search strings.
i. New application-callable function: rl_clear_history. Clears the history list
and frees all readline-associated private data.
j. New user-settable variable, show-mode-in-prompt, adds a characters to the
beginning of the prompt indicating the current editing mode.
k. New application-settable variable: rl_input_available_hook; function to be
called when readline needs to check whether there is data available on its
input source. The default hook checks rl_instream.
l. Readline calls an application-set event hook (rl_signal_event_hook) after
it gets a signal while reading input (read returns -1/EINTR but readline
does not handle the signal immediately) to allow the application to handle
or otherwise note it. Not currently called for SIGHUP or SIGTERM.
m. If the user-settable variable `history-size' is set to a value less than
0, the history list size is unlimited.
n. When creating shared libraries on Mac OS X, the pathname written into the
library (install_name) no longer includes the minor version number.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-6.2,
and the previous version, readline-6.1.
1. Changes to Readline
a. Fixed a bug that caused the unconverted filename to be added to the list of
completions when the application specified filename conversion functions.
b. Fixed a bug that caused the wrong filename to be passed to opendir when the
application has specified a filename dequoting function.
c. Fixed a bug when repeating a character search in vi mode in the case where
there was no search to repeat.
d. When show-all-if-ambiguous is set, the completion routines no longer insert
a common match prefix that is shorter than the text being completed.
e. The full set of vi editing commands may now be used in callback mode.
f. Fixed a bug that caused readline to not update its idea of the terminal
dimensions while running in `no-echo' mode.
h. Fixed a bug that caused readline to dump core if an application called
rl_prep_terminal without setting rl_instream.
i. Fixed a bug that caused meta-prefixed characters bound to incremental
search forward or backward to not be recognized if they were typed
subsequently.
j. The incremental search code treats key sequences that map to the same
functions as (default) ^G, ^W, and ^Y as equivalent to those characters.
k. Fixed a bug in menu-complete that caused it to misbehave with large
negative argument.
l. Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked
at the end of the line.
m. Fixed a bug that made an explicit argument of 0 to yank-last-arg behave
as if it were a negative argument.
n. Fixed a bug that caused directory names in words to be completed to not
be dequoted correctly.
2. New Features in Readline
a. The history library does not try to write the history filename in the
current directory if $HOME is unset. This closes a potential security
problem if the application does not specify a history filename.
b. New bindable variable `completion-display-width' to set the number of
columns used when displaying completions.
c. New bindable variable `completion-case-map' to cause case-insensitive
completion to treat `-' and `_' as identical.
d. There are new bindable vi-mode command names to avoid readline's case-
insensitive matching not allowing them to be bound separately.
e. New bindable variable `menu-complete-display-prefix' causes the menu
completion code to display the common prefix of the possible completions
before cycling through the list, instead of after.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-6.1,
and the previous version, readline-6.0.
1. Changes to Readline
a. The SIGWINCH signal handler now avoids calling the redisplay code if
one arrives while in the middle of redisplay.
b. Changes to the timeout code to make sure that timeout values greater
than one second are handled better.
c. Fixed a bug in the redisplay code that was triggered by a prompt
containing invisible characters exactly the width of the screen.
d. Fixed a bug in the redisplay code encountered when running in horizontal
scroll mode.
e. Fixed a bug that prevented menu completion from properly completing
filenames.
f. Fixed a redisplay bug caused by a multibyte character causing a line to
wrap.
g. Fixed a bug that caused key sequences of two characters to not be
recognized when a longer sequence identical in the first two characters
was bound.
h. Fixed a bug that caused history expansion to be attempted on $'...'
single-quoted strings.
i. Fixed a bug that caused incorrect redisplay when the prompt contained
multibyte characters in an `invisible' sequence bracketed by \[ and
\].
j. Fixed a bug that caused history expansion to short-circuit after
encountering a multibyte character.
k. Fixed a bug that caused applications using the callback interface to not
react to SIGINT (or other signals) until another character arrived.
2. New Features in Readline
a. New bindable function: menu-complete-backward.
b. In the vi insertion keymap, C-n is now bound to menu-complete by default,
and C-p to menu-complete-backward.
c. When in vi command mode, repeatedly hitting ESC now does nothing, even
when ESC introduces a bound key sequence. This is closer to how
historical vi behaves.
d. New bindable function: skip-csi-sequence. Can be used as a default to
consume key sequences generated by keys like Home and End without having
to bind all keys.
e. New application-settable function: rl_filename_rewrite_hook. Can be used
to rewite or modify filenames read from the file system before they are
compared to the word to be completed.
f. New bindable variable: skip-completed-text, active when completing in the
middle of a word. If enabled, it means that characters in the completion
that match characters in the remainder of the word are "skipped" rather
than inserted into the line.
g. The pre-readline-6.0 version of menu completion is available as
"old-menu-complete" for users who do not like the readline-6.0 version.
h. New bindable variable: echo-control-characters. If enabled, and the
tty ECHOCTL bit is set, controls the echoing of characters corresponding
to keyboard-generated signals.
i. New bindable variable: enable-meta-key. Controls whether or not readline
sends the smm/rmm sequences if the terminal indicates it has a meta key
that enables eight-bit characters.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-6.0,
and the previous version, readline-5.2.
1. Changes to Readline
a. Fixed a number of redisplay errors in environments supporting multibyte
characters.
b. Fixed bugs in vi command mode that caused motion commands to inappropriately
set the mark.
c. When using the arrow keys in vi insertion mode, readline allows movement
beyond the current end of the line (unlike command mode).
d. Fixed bugs that caused readline to loop when the terminal has been taken
away and reads return -1/EIO.
e. Fixed bugs in redisplay occurring when displaying prompts containing
invisible characters.
f. Fixed a bug that caused the completion append character to not be reset to
the default after an application-specified completion function changed it.
g. Fixed a problem that caused incorrect positioning of the cursor while in
emacs editing mode when moving forward at the end of a line while using
a locale supporting multibyte characters.
h. Fixed an off-by-one error that caused readline to drop every 511th
character of buffered input.
i. Fixed a bug that resulted in SIGTERM not being caught or cleaned up.
j. Fixed redisplay bugs caused by multiline prompts with invisible characters
or no characters following the final newline.
k. Fixed redisplay bug caused by prompts consisting solely of invisible
characters.
l. Fixed a bug in the code that buffers characters received very quickly in
succession which caused characters to be dropped.
m. Fixed a bug that caused readline to reference uninitialized data structures
if it received a SIGWINCH before completing initialzation.
n. Fixed a bug that caused the vi-mode `last command' to be set incorrectly
and therefore unrepeatable.
o. Fixed a bug that caused readline to disable echoing when it was being used
with an output file descriptor that was not a terminal.
p. Readline now blocks SIGINT while manipulating internal data structures
during redisplay.
q. Fixed a bug in redisplay that caused readline to segfault when pasting a
very long line (over 130,000 characters).
r. Fixed bugs in redisplay when using prompts with no visible printing
characters.
s. Fixed a bug that caused redisplay errors when using prompts with invisible
characters and numeric arguments to a command in a multibyte locale.
t. Fixed a bug that caused redisplay errors when using prompts with invisible
characters spanning more than two physical screen lines.
2. New Features in Readline
a. A new variable, rl_sort_completion_matches; allows applications to inhibit
match list sorting (but beware: some things don't work right if
applications do this).
b. A new variable, rl_completion_invoking_key; allows applications to discover
the key that invoked rl_complete or rl_menu_complete.
c. The functions rl_block_sigint and rl_release_sigint are now public and
available to calling applications who want to protect critical sections
(like redisplay).
d. The functions rl_save_state and rl_restore_state are now public and
available to calling applications; documented rest of readline's state
flag values.
e. A new user-settable variable, `history-size', allows setting the maximum
number of entries in the history list.
f. There is a new implementation of menu completion, with several improvements
over the old; the most notable improvement is a better `completions
browsing' mode.
g. The menu completion code now uses the rl_menu_completion_entry_function
variable, allowing applications to provide their own menu completion
generators.
h. There is support for replacing a prefix of a pathname with a `...' when
displaying possible completions. This is controllable by setting the
`completion-prefix-display-length' variable. Matches with a common prefix
longer than this value have the common prefix replaced with `...'.
i. There is a new `revert-all-at-newline' variable. If enabled, readline will
undo all outstanding changes to all history lines when `accept-line' is
executed.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-5.2,
and the previous version, readline-5.1.
1. Changes to Readline
a. Fixed a problem that caused segmentation faults when using readline in
callback mode and typing consecutive DEL characters on an empty line.
b. Fixed several redisplay problems with multibyte characters, all having to
do with the different code paths and variable meanings between single-byte
and multibyte character redisplay.
c. Fixed a problem with key sequence translation when presented with the
sequence \M-\C-x.
d. Fixed a problem that prevented the `a' command in vi mode from being
undone and redone properly.
e. Fixed a problem that prevented empty inserts in vi mode from being undone
properly.
f. Fixed a problem that caused readline to initialize with an incorrect idea
of whether or not the terminal can autowrap.
g. Fixed output of key bindings (like bash `bind -p') to honor the setting of
convert-meta and use \e where appropriate.
h. Changed the default filename completion function to call the filename
dequoting function if the directory completion hook isn't set. This means
that any directory completion hooks need to dequote the directory name,
since application-specific hooks need to know how the word was quoted,
even if no other changes are made.
i. Fixed a bug with creating the prompt for a non-interactive search string
when there are non-printing characters in the primary prompt.
j. Fixed a bug that caused prompts with invisible characters to be redrawn
multiple times in a multibyte locale.
k. Fixed a bug that could cause the key sequence scanning code to return the
wrong function.
l. Fixed a problem with the callback interface that caused it to fail when
using multi-character keyboard macros.
m. Fixed a bug that could cause a core dump when an edited history entry was
re-executed under certain conditions.
n. Fixed a bug that caused readline to reference freed memory when attmpting
to display a portion of the prompt.
o. Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
the prompt and input line multiple times.
p. Fixed history expansion to not be confused by here-string redirection.
q. Readline no longer treats read errors by converting them to newlines, as
it does with EOF. This caused partial lines to be returned from readline().
r. Fixed a redisplay bug that occurred in multibyte-capable locales when the
prompt was one character longer than the screen width.
2. New Features in Readline
a. Calling applications can now set the keyboard timeout to 0, allowing
poll-like behavior.
b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
the default last-ditch startup file.
c. The history file reading functions now allow windows-like \r\n line
terminators.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-5.1,
and the previous version, readline-5.0.
1. Changes to Readline
a. Fixed a bug that caused multiliine prompts to be wrapped and displayed
incorrectly.
b. Fixed a bug that caused ^P/^N in emacs mode to fail to display the current
line correctly.
c. Fixed a problem in computing the number of invisible characters on the first
line of a prompt whose length exceeds the screen width.
d. Fixed vi-mode searching so that failure preserves the current line rather
than the last line in the history list.
e. Fixed the vi-mode `~' command (change-case) to have the correct behavior at
end-of-line when manipulating multibyte characters.
f. Fixed the vi-mode `r' command (change-char) to have the correct behavior at
end-of-line when manipulating multibyte characters.
g. Fixed multiple bugs in the redisplay of multibyte characters: displaying
prompts longer than the screen width containing multibyte characters,
h. Fix the calculation of the number of physical characters in the prompt
string when it contains multibyte characters.
i. A non-zero value for the `rl_complete_suppress_append' variable now causes
no `/' to be appended to a directory name.
j. Fixed forward-word and backward-word to work when words contained
multibyte characters.
k. Fixed a bug in finding the delimiter of a `?' substring when performing
history expansion in a locale that supports multibyte characters.
l. Fixed a memory leak caused by not freeing the timestamp in a history entry.
m. Fixed a bug that caused "\M-x" style key bindings to not obey the setting
of the `convert-meta' variable.
n. Fixed saving and restoring primary prompt when prompting for incremental
and non-incremental searches; search prompts now display multibyte
characters correctly.
o. Fixed a bug that caused keys originally bound to self-insert but shadowed
by a multi-character key sequence to not be inserted.
p. Fixed code so rl_prep_term_function and rl_deprep_term_function aren't
dereferenced if NULL (matching the documentation).
q. Extensive changes to readline to add enough state so that commands
requiring additional characters (searches, multi-key sequences, numeric
arguments, commands requiring an additional specifier character like
vi-mode change-char, etc.) work without synchronously waiting for
additional input.
r. Lots of changes so readline builds and runs on MinGW.
s. Readline no longer tries to modify the terminal settings when running in
callback mode.
t. The Readline display code no longer sets the location of the last invisible
character in the prompt if the \[\] sequence is empty.
u. The `change-case' command now correctly changes the case of multibyte
characters.
v. Changes to the shared library construction scripts to deal with Windows
DLL naming conventions for Cygwin.
w. Fixed the redisplay code to avoid core dumps resulting from a poorly-timed
SIGWINCH.
x. Fixed the non-incremental search code in vi mode to dispose of any current
undo list when copying a line from the history into the current editing
buffer.
y. Fixed a bug that caused reversing the incremental search direction to
not work correctly.
z. Fixed the vi-mode `U' command to only undo up to the first time insert mode
was entered, as Posix specifies.
aa. Fixed a bug in the vi-mode `r' command that left the cursor in the wrong
place.
bb. Fixed a redisplay bug caused by moving the cursor vertically to a line
with invisible characters in the prompt in a multibyte locale.
cc. Fixed a bug that could cause the terminal special chars to be bound in the
wrong keymap in vi mode.
2. New Features in Readline
a. The key sequence sent by the keypad `delete' key is now automatically
bound to delete-char.
b. A negative argument to menu-complete now cycles backward through the
completion list.
c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
readline will bind the terminal special characters to their readline
equivalents when it's called (on by default).
d. New bindable command: vi-rubout. Saves deleted text for possible
reinsertion, as with any vi-mode `text modification' command; `X' is bound
to this in vi command mode.
e. If the rl_completion_query_items is set to a value < 0, readline never
asks the user whether or not to view the possible completions.
f. The `C-w' binding in incremental search now understands multibyte
characters.
g. New application-callable auxiliary function, rl_variable_value, returns
a string corresponding to a readline variable's value.
h. When parsing inputrc files and variable binding commands, the parser
strips trailing whitespace from values assigned to boolean variables
before checking them.
i. A new external application-controllable variable that allows the LINES
and COLUMNS environment variables to set the window size regardless of
what the kernel returns.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-5.0,
and the previous version, readline-4.3.
1. Changes to Readline
a. Fixes to avoid core dumps because of null pointer references in the
multibyte character code.
b. Fix to avoid infinite recursion caused by certain key combinations.
c. Fixed a bug that caused the vi-mode `last command' to be set incorrectly.
d. Readline no longer tries to read ahead more than one line of input, even
when more is available.
e. Fixed the code that adjusts the point to not mishandle null wide
characters.
f. Fixed a bug in the history expansion `g' modifier that caused it to skip
every other match.
g. Fixed a bug that caused the prompt to overwrite previous output when the
output doesn't contain a newline and the locale supports multibyte
characters. This same change fixes the problem of readline redisplay
slowing down dramatically as the line gets longer in multibyte locales.
h. History traversal with arrow keys in vi insertion mode causes the cursor
to be placed at the end of the new line, like in emacs mode.
i. The locale initialization code does a better job of using the right
precedence and defaulting when checking the appropriate environment
variables.
j. Fixed the history word tokenizer to handle <( and >( better when used as
part of bash.
k. The overwrite mode code received several bug fixes to improve undo.
l. Many speedups to the multibyte character redisplay code.
m. The callback character reading interface should not hang waiting to read
keyboard input.
n. Fixed a bug with redoing vi-mode `s' command.
o. The code that initializes the terminal tracks changes made to the terminal
special characters with stty(1) (or equivalent), so that these changes
are reflected in the readline bindings. New application-callable function
to make it work: rl_tty_unset_default_bindings().
p. Fixed a bug that could cause garbage to be inserted in the buffer when
changing character case in vi mode when using a multibyte locale.
q. Fixed a bug in the redisplay code that caused problems on systems
supporting multibyte characters when moving between history lines when the
new line has more glyphs but fewer bytes.
r. Undo and redo now work better after exiting vi insertion mode.
s. Make sure system calls are restarted after a SIGWINCH is received using
SA_RESTART.
t. Improvements to the code that displays possible completions when using
multibyte characters.
u. Fixed a problem when parsing nested if statements in inputrc files.
v. The completer now takes multibyte characters into account when looking for
quoted substrings on which to perform completion.
w. The history search functions now perform better bounds checking on the
history list.
x. Change to history expansion functions to treat `^' as equivalent to word
one, as the documention states.
y. Some changes to the display code to improve display and redisplay of
multibyte characters.
z. Changes to speed up the multibyte character redisplay code.
aa. Fixed a bug in the vi-mode `E' command that caused it to skip over the
last character of a word if invoked while point was on the word's
next-to-last character.
bb. Fixed a bug that could cause incorrect filename quoting when
case-insensitive completion was enabled and the word being completed
contained backslashes quoting word break characters.
cc. Fixed a bug in redisplay triggered when the prompt string contains
invisible characters.
dd. Fixed some display (and other) bugs encountered in multibyte locales
when a non-ascii character was the last character on a line.
ee. Fixed some display bugs caused by multibyte characters in prompt strings.
ff. Fixed a problem with history expansion caused by non-whitespace characters
used as history word delimiters.
gg. Fixed a problem that could cause readline to refer to freed memory when
moving between history lines while doing searches.
hh. Improvements to the code that expands and displays prompt strings
containing multibyte characters.
ii. Fixed a problem with vi-mode not correctly remembering the numeric argument
to the last `c'hange command for later use with `.'.
jj. Fixed a bug in vi-mode that caused multi-digit count arguments to work
incorrectly.
kk. Fixed a problem in vi-mode that caused the last text modification command
to not be remembered across different command lines.
ll. Fixed problems with changing characters and changing case at the end of
the line.
mm. Fixed a problem with readline saving the contents of the current line
before beginning a non-interactive search.
nn. Fixed a problem with EOF detection when using rl_event_hook.
oo. Fixed a problem with the vi mode `p' and `P' commands ignoring numeric
arguments.
2. New Features in Readline
a. History expansion has a new `a' modifier equivalent to the `g' modifier
for compatibility with the BSD csh.
b. History expansion has a new `G' modifier equivalent to the BSD csh `g'
modifier, which performs a substitution once per word.
c. All non-incremental search operations may now undo the operation of
replacing the current line with the history line.
d. The text inserted by an `a' command in vi mode can be reinserted with
`.'.
e. New bindable variable, `show-all-if-unmodified'. If set, the readline
completer will list possible completions immediately if there is more
than one completion and partial completion cannot be performed.
f. There is a new application-callable `free_history_entry()' function.
g. History list entries now contain timestamp information; the history file
functions know how to read and write timestamp information associated
with each entry.
h. Four new key binding functions have been added:
rl_bind_key_if_unbound()
rl_bind_key_if_unbound_in_map()
rl_bind_keyseq_if_unbound()
rl_bind_keyseq_if_unbound_in_map()
i. New application variable, rl_completion_quote_character, set to any
quote character readline finds before it calls the application completion
function.
j. New application variable, rl_completion_suppress_quote, settable by an
application completion function. If set to non-zero, readline does not
attempt to append a closing quote to a completed word.
k. New application variable, rl_completion_found_quote, set to a non-zero
value if readline determines that the word to be completed is quoted.
Set before readline calls any application completion function.
l. New function hook, rl_completion_word_break_hook, called when readline
needs to break a line into words when completion is attempted. Allows
the word break characters to vary based on position in the line.
m. New bindable command: unix-filename-rubout. Does the same thing as
unix-word-rubout, but adds `/' to the set of word delimiters.
n. When listing completions, directories have a `/' appended if the
`mark-directories' option has been enabled.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-4.3,
and the previous version, readline-4.2a.
1. Changes to Readline
a. Fixed output of comment-begin character when listing variable values.
b. Added some default key bindings for common escape sequences produced by
HOME and END keys.
c. Fixed the mark handling code to be more emacs-compatible.
d. A bug was fixed in the code that prints possible completions to keep it
from printing empty strings in certain circumstances.
e. Change the key sequence printing code to print ESC as M\- if ESC is a
meta-prefix character -- it's easier for users to understand than \e.
f. Fixed unstifle_history() to return values that match the documentation.
g. Fixed the event loop (rl_event_hook) to handle the case where the input
file descriptor is invalidated.
h. Fixed the prompt display code to work better when the application has a
custom redisplay function.
i. Changes to make reading and writing the history file a little faster, and
to cope with huge history files without calling abort(3) from xmalloc.
j. The vi-mode `S' and `s' commands are now undone correctly.
k. Fixed a problem which caused the display to be messed up when the last
line of a multi-line prompt (possibly containing invisible characters)
was longer than the screen width.
2. New Features in Readline
a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both
be bound to readline functions. Now the arrow keys may be used in vi
insert mode.
b. When listing completions, and the number of lines displayed is more than
the screen length, readline uses an internal pager to display the results.
This is controlled by the `page-completions' variable (default on).
c. New code to handle editing and displaying multibyte characters.
d. The behavior introduced in bash-2.05a of deciding whether or not to
append a slash to a completed name that is a symlink to a directory has
been made optional, controlled by the `mark-symlinked-directories'
variable (default is the 2.05a behavior).
e. The `insert-comment' command now acts as a toggle if given a numeric
argument: if the first characters on the line don't specify a
comment, insert one; if they do, delete the comment text
f. New application-settable completion variable:
rl_completion_mark_symlink_dirs, allows an application's completion
function to temporarily override the user's preference for appending
slashes to names which are symlinks to directories.
g. New function available to application completion functions:
rl_completion_mode, to tell how the completion function was invoked
and decide which argument to supply to rl_complete_internal (to list
completions, etc.).
h. Readline now has an overwrite mode, toggled by the `overwrite-mode'
bindable command, which could be bound to `Insert'.
i. New application-settable completion variable:
rl_completion_suppress_append, inhibits appending of
rl_completion_append_character to completed words.
j. New key bindings when reading an incremental search string: ^W yanks
the currently-matched word out of the current line into the search
string; ^Y yanks the rest of the current line into the search string,
DEL or ^H deletes characters from the search string.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-4.2a,
and the previous version, readline-4.2.
1. Changes to Readline
a. More `const' and type casting fixes.
b. Changed rl_message() to use vsnprintf(3) (if available) to fix buffer
overflow problems.
c. The completion code no longer appends a `/' or ` ' to a match when
completing a symbolic link that resolves to a directory name, unless
the match does not add anything to the word being completed. This
means that a tab will complete the word up to the full name, but not
add anything, and a subsequent tab will add a slash.
d. Fixed a trivial typo that made the vi-mode `dT' command not work.
e. Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert.
f. Fixed the tty code so that ^V works more than once.
g. Changed the use of __P((...)) for function prototypes to PARAMS((...))
because the use of __P in typedefs conflicted g++ and glibc.
h. The completion code now attempts to do a better job of preserving the
case of the word the user typed if ignoring case in completions.
i. Readline defaults to not echoing the input and lets the terminal
initialization code enable echoing if there is a controlling terminal.
j. The key binding code now processes only two hex digits after a `\x'
escape sequence, and the documentation was changed to note that the
octal and hex escape sequences result in an eight-bit value rather
than strict ASCII.
k. Fixed a few places where negative array subscripts could have occurred.
l. Fixed the vi-mode code to use a better method to determine the bounds of
the array used to hold the marks, and to avoid out-of-bounds references.
m. Fixed the defines in chardefs.h to work better when chars are signed.
n. Fixed configure.in to use the new names for bash autoconf macros.
o. Readline no longer attempts to define its own versions of some ctype
macros if they are implemented as functions in libc but not as macros in
.
p. Fixed a problem where rl_backward could possibly set point to before
the beginning of the line.
q. Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause
include file problems.
2. New Features in Readline
a. Added extern declaration for rl_get_termcap to readline.h, making it a
public function (it was always there, just not in readline.h).
b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402,
RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION.
d. New bindable boolean readline variable: match-hidden-files. Controls
completion of files beginning with a `.' (on Unix). Enabled by default.
e. The history expansion code now allows any character to terminate a
`:first-' modifier, like csh.
f. The incremental search code remembers the last search string and uses
it if ^R^R is typed without a search string.
h. New bindable variable `history-preserve-point'. If set, the history
code attempts to place the user at the same location on each history
line retrived with previous-history or next-history.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-4.2,
and the previous version, readline-4.1.
1. Changes to Readline
a. When setting the terminal attributes on systems using `struct termio',
readline waits for output to drain before changing the attributes.
b. A fix was made to the history word tokenization code to avoid attempts to
dereference a null pointer.
c. Readline now defaults rl_terminal_name to $TERM if the calling application
has left it unset, and tries to initialize with the resultant value.
d. Instead of calling (*rl_getc_function)() directly to get input in certain
places, readline now calls rl_read_key() consistently.
e. Fixed a bug in the completion code that allowed a backslash to quote a
single quote inside a single-quoted string.
f. rl_prompt is no longer assigned directly from the argument to readline(),
but uses memory allocated by readline. This allows constant strings to
be passed to readline without problems arising when the prompt processing
code wants to modify the string.
g. Fixed a bug that caused non-interactive history searches to return the
wrong line when performing multiple searches backward for the same string.
h. Many variables, function arguments, and function return values are now
declared `const' where appropriate, to improve behavior when linking with
C++ code.
i. The control character detection code now works better on systems where
`char' is unsigned by default.
j. The vi-mode numeric argument is now capped at 999999, just like emacs mode.
k. The Function, CPFunction, CPPFunction, and VFunction typedefs have been
replaced with a set of specific prototyped typedefs, though they are
still in the readline header files for backwards compatibility.
m. Nearly all of the (undocumented) internal global variables in the library
now have an _rl_ prefix -- there were a number that did not, like
screenheight, screenwidth, alphabetic, etc.
n. The ding() convenience function has been renamed to rl_ding(), though the
old function is still defined for backwards compatibility.
o. The completion convenience functions filename_completion_function,
username_completion_function, and completion_matches now have an rl_
prefix, though the old names are still defined for backwards compatibility.
p. The functions shared by readline and bash (linkage is satisfied from bash
when compiling with bash, and internally otherwise) now have an sh_ prefix.
q. Changed the shared library creation procedure on Linux and BSD/OS 4.x so
that the `soname' contains only the major version number rather than the
major and minor numbers.
r. Fixed a redisplay bug that occurred when the prompt spanned more than one
physical line and contained invisible characters.
s. Added a missing `includedir' variable to the Makefile.
t. When installing the shared libraries, make sure symbolic links are relative.
u. Added configure test so that it can set `${MAKE}' appropriately.
v. Fixed a bug in rl_forward that could cause the point to be set to before
the beginning of the line in vi mode.
w. Fixed a bug in the callback read-char interface to make it work when a
readline function pushes some input onto the input stream with
rl_execute_next (like the incremental search functions).
x. Fixed a file descriptor leak in the history file manipulation code that
was tripped when attempting to truncate a non-regular file (like
/dev/null).
y. Changes to make all of the exported readline functions declared in
readline.h have an rl_ prefix (rltty_set_default_bindings is now
rl_tty_set_default_bindings, crlf is now rl_crlf, etc.)
z. The formatted documentation included in the base readline distribution
is no longer removed on a `make distclean'.
aa. Some changes were made to avoid gcc warnings with -Wall.
bb. rl_get_keymap_by_name now finds keymaps case-insensitively, so
`set keymap EMACS' works.
cc. The history file writing and truncation functions now return a useful
status on error.
dd. Fixed a bug that could cause applications to dereference a NULL pointer
if a NULL second argument was passed to history_expand().
ee. If a hook function assigned to rl_event_hook sets rl_done to a non-zero
value, rl_read_key() now immediately returns '\n' (which is assumed to
be bound to accept-line).
2. New Features in Readline
a. The blink timeout for paren matching is now settable by applications,
via the rl_set_paren_blink_timeout() function.
b. _rl_executing_macro has been renamed to rl_executing_macro, which means
it's now part of the public interface.
c. Readline has a new variable, rl_readline_state, which is a bitmap that
encapsulates the current state of the library; intended for use by
callbacks and hook functions.
d. rlfe has a new -l option to log input and output (-a appends to logfile),
a new -n option to set the readline application name, and -v and -h
options for version and help information.
e. rlfe can now perform filename completion for the inferior process if the
OS has a /proc//cwd that can be read with readlink(2) to get the
inferior's current working directory.
f. A new file, rltypedefs.h, contains the new typedefs for function pointers
and is installed by `make install'.
g. New application-callable function rl_set_prompt(const char *prompt):
expands its prompt string argument and sets rl_prompt to the result.
h. New application-callable function rl_set_screen_size(int rows, int cols):
public method for applications to set readline's idea of the screen
dimensions.
i. The history example program (examples/histexamp.c) is now built as one
of the examples.
j. The documentation has been updated to cover nearly all of the public
functions and variables declared in readline.h.
k. New function, rl_get_screen_size (int *rows, int *columns), returns
readline's idea of the screen dimensions.
l. The timeout in rl_gather_tyi (readline keyboard input polling function)
is now settable via a function (rl_set_keyboard_input_timeout()).
m. Renamed the max_input_history variable to history_max_entries; the old
variable is maintained for backwards compatibility.
n. The list of characters that separate words for the history tokenizer is
now settable with a variable: history_word_delimiters. The default
value is as before.
o. There is a new history.3 manual page documenting the history library.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-4.1,
and the previous version, readline-4.0.
1. Changes to Readline
a. Changed the HTML documents so that the table-of-contents is no longer
a separate file.
b. Changes to the shared object configuration for: Irix 5.x, Irix 6.x,
OSF/1.
c. The shared library major and minor versions are now constructed
automatically by configure and substituted into the makefiles.
d. It's now possible to install the shared libraries separately from the
static libraries.
e. The history library tries to truncate the history file only if it is a
regular file.
f. A bug that caused _rl_dispatch to address negative array indices on
systems with signed chars was fixed.
g. rl-yank-nth-arg now leaves the history position the same as when it was
called.
h. Changes to the completion code to handle MS-DOS drive-letter:pathname
filenames.
i. Completion is now case-insensitive by default on MS-DOS.
j. Fixes to the history file manipulation code for MS-DOS.
k. Readline attempts to bind the arrow keys to appropriate defaults on MS-DOS.
l. Some fixes were made to the redisplay code for better operation on MS-DOS.
m. The quoted-insert code will now insert tty special chars like ^C.
n. A bug was fixed that caused the display code to reference memory before
the start of the prompt string.
o. More support for __EMX__ (OS/2).
p. A bug was fixed in readline's signal handling that could cause infinite
recursion in signal handlers.
q. A bug was fixed that caused the point to be less than zero when rl_forward
was given a very large numeric argument.
r. The vi-mode code now gets characters via the application-settable value
of rl_getc_function rather than calling rl_getc directly.
s. The history file code now uses O_BINARY mode when reading and writing
the history file on cygwin32.
t. Fixed a bug in the redisplay code for lines with more than 256 line
breaks.
u. A bug was fixed which caused invisible character markers to not be
stripped from the prompt string if the terminal was in no-echo mode.
v. Readline no longer tries to get the variables it needs for redisplay
from the termcap entry if the calling application has specified its
own redisplay function. Readline treats the terminal as `dumb' in
this case.
w. Fixes to the SIGWINCH code so that a multiple-line prompt with escape
sequences is redrawn correctly.
x. Changes to the install and install-shared targets so that the libraries
and header files are installed separately.
2. New Features in Readline
a. A new Readline `user manual' is in doc/rluserman.texinfo.
b. Parentheses matching is now always compiled into readline, and enabled
or disabled when the value of the `blink-matching-paren' variable is
changed.
c. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
d. MS-DOS systems now use ~/_history as the default history file.
e. history-search-{forward,backward} now leave the point at the end of the
line when the string to search for is empty, like
{reverse,forward}-search-history.
f. history-search-{forward,backward} now leave the last history line found
in the readline buffer if the second or subsequent search fails.
g. New function for use by applications: rl_on_new_line_with_prompt, used
when an application displays the prompt itself before calling readline().
h. New variable for use by applications: rl_already_prompted. An application
that displays the prompt itself before calling readline() must set this to
a non-zero value.
i. A new variable, rl_gnu_readline_p, always 1. The intent is that an
application can verify whether or not it is linked with the `real'
readline library or some substitute.
j. Per Bothner's `rlfe' (pronounced `Ralphie') readline front-end program
is included in the examples subdirectory, though it is not built
by default.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-4.0,
and the previous version, readline-2.2.
1. Changes to Readline
a. The version number is now 4.0, to match the major and minor version
numbers on the shared readline and history libraries. Future
releases will maintain the identical numbering.
b. Fixed a typo in the `make install' recipe that copied libreadline.a
to libhistory.old right after installing it.
c. The readline and history info files are now installed out of the source
directory if they are not found in the build directory.
d. The library no longer exports a function named `savestring' -- backwards
compatibility be damned.
e. There is no longer any #ifdef SHELL code in the source files.
f. Some changes were made to the key binding code to fix memory leaks and
better support Win32 systems.
g. Fixed a silly typo in the paren matching code -- it's microseconds, not
milliseconds.
h. The readline library should be compilable by C++ compilers.
i. The readline.h public header file now includes function prototypes for
all readline functions, and some changes were made to fix errors in the
source files uncovered by the use of prototypes.
j. The maximum numeric argument is now clamped at 1000000.
k. Fixes to rl_yank_last_arg to make it behave better.
l. Fixed a bug in the display code that caused core dumps if the prompt
string length exceeded 1024 characters.
m. The menu completion code was fixed to properly insert a single completion
if there is only one match.
n. A bug was fixed that caused the display code to improperly display tabs
after newlines.
o. A fix was made to the completion code in which a typo caused the wrong
value to be passed to the function that computed the longest common
prefix of the list of matches.
p. The completion code now checks the value of rl_filename_completion_desired,
which is set by application-supplied completion functions to indicate
that filename completion is being performed, to decide whether or not to
call an application-supplied `ignore completions' function.
q. Code was added to the history library to catch history substitutions
using `&' without a previous history substitution or search having been
performed.
2. New Features in Readline
a. There is a new script, support/shobj-conf, to do system-specific shared
object and library configuration. It generates variables for configure
to substitute into makefiles. The README file provides a detailed
explanation of the shared library creation process.
b. Shared libraries and objects are now built in the `shlib' subdirectory.
There is a shlib/Makefile.in to control the build process. `make shared'
from the top-level directory is still the right way to build shared
versions of the libraries.
c. rlconf.h is now installed, so applications can find out which features
have been compiled into the installed readline and history libraries.
d. rlstdc.h is now an installed header file.
e. Many changes to the signal handling:
o Readline now catches SIGQUIT and cleans up the tty before returning;
o A new variable, rl_catch_signals, is available to application writers
to indicate to readline whether or not it should install its own
signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
SIGTTIN, and SIGTTOU;
o A new variable, rl_catch_sigwinch, is available to application
writers to indicate to readline whether or not it should install its
own signal handler for SIGWINCH, which will chain to the calling
applications's SIGWINCH handler, if one is installed;
o There is a new function, rl_free_line_state, for application signal
handlers to call to free up the state associated with the current
line after receiving a signal;
o There is a new function, rl_cleanup_after_signal, to clean up the
display and terminal state after receiving a signal;
o There is a new function, rl_reset_after_signal, to reinitialize the
terminal and display state after an application signal handler
returns and readline continues
f. There is a new function, rl_resize_terminal, to reset readline's idea of
the screen size after a SIGWINCH.
g. New public functions: rl_save_prompt and rl_restore_prompt. These were
previously private functions with a `_' prefix. These functions are
used when an application wants to write a message to the `message area'
with rl_message and have the prompt restored correctly when the message
is erased.
h. New function hook: rl_pre_input_hook, called just before readline starts
reading input, after initialization.
i. New function hook: rl_display_matches_hook, called when readline would
display the list of completion matches. The new function
rl_display_match_list is what readline uses internally, and is available
for use by application functions called via this hook.
j. New bindable function, delete-char-or-list, like tcsh.
k. A new variable, rl_erase_empty_line, which, if set by an application using
readline, will cause readline to erase, prompt and all, lines on which the
only thing typed was a newline.
l. There is a new script, support/shlib-install, to install and uninstall
the shared readline and history libraries.
m. A new bindable variable, `isearch-terminators', which is a string
containing the set of characters that should terminate an incremental
search without being executed as a command.
n. A new bindable function, forward-backward-delete-char.
-------------------------------------------------------------------------------
This document details the changes between this version, readline-2.2,
and the previous version, readline-2.1.
1. Changes to Readline
a. Added a missing `extern' to a declaration in readline.h that kept
readline from compiling cleanly on some systems.
b. The history file is now opened with mode 0600 when it is written for
better security.
c. Changes were made to the SIGWINCH handling code so that prompt redisplay
is done better.
d. ^G now interrupts incremental searches correctly.
e. A bug that caused a core dump when the set of characters to be quoted
when completing words was empty was fixed.
f. Fixed a problem in the readline test program rltest.c that caused a core
dump.
g. The code that handles parser directives in inputrc files now displays
more error messages.
h. The history expansion code was fixed so that the appearance of the
history comment character at the beginning of a word inhibits history
expansion for that word and the rest of the input line.
i. The code that prints completion listings now behaves better if one or
more of the filenames contains non-printable characters.
j. The time delay when showing matching parentheses is now 0.5 seconds.
2. New Features in Readline
a. There is now an option for `iterative' yank-last-arg handline, so a user
can keep entering `M-.', yanking the last argument of successive history
lines.
b. New variable, `print-completions-horizontally', which causes completion
matches to be displayed across the screen (like `ls -x') rather than up
and down the screen (like `ls').
c. New variable, `completion-ignore-case', which causes filename completion
and matching to be performed case-insensitively.
d. There is a new bindable command, `magic-space', which causes history
expansion to be performed on the current readline buffer and a space to
be inserted into the result.
e. There is a new bindable command, `menu-complete', which enables tcsh-like
menu completion (successive executions of menu-complete insert a single
completion match, cycling through the list of possible completions).
f. There is a new bindable command, `paste-from-clipboard', for use on Win32
systems, to insert the text from the Win32 clipboard into the editing
buffer.
g. The key sequence translation code now understands printf-style backslash
escape sequences, including \NNN octal escapes. These escape sequences
may be used in key sequence definitions or macro values.
h. An `$include' inputrc file parser directive has been added.
readline-7.0/NEWS 000664 000436 000024 00000030607 12650434135 013736 0 ustar 00chet staff 000000 000000 This is a terse description of the new features added to readline-7.0 since
the release of readline-6.3.
New Features in Readline
a. The history truncation code now uses the same error recovery mechansim as
the history writing code, and restores the old version of the history file
on error. The error recovery mechanism handles symlinked history files.
b. There is a new bindable variable, `enable-bracketed-paste', which enables
support for a terminal's bracketed paste mode.
c. The editing mode indicators can now be strings and are user-settable
(new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string'
variables). Mode strings can contain invisible character sequences.
Setting mode strings to null strings restores the defaults.
d. Prompt expansion adds the mode string to the last line of a multi-line
prompt (one with embedded newlines).
e. There is a new bindable variable, `colored-completion-prefix', which, if
set, causes the common prefix of a set of possible completions to be
displayed in color.
f. There is a new bindable command `vi-yank-pop', a vi-mode version of emacs-
mode yank-pop.
g. The redisplay code underwent several efficiency improvements for multibyte
locales.
h. The insert-char function attempts to batch-insert all pending typeahead
that maps to self-insert, as long as it is coming from the terminal.
i. rl_callback_sigcleanup: a new application function that can clean up and
unset any state set by readline's callback mode. Intended to be used
after a signal.
j. If an incremental search string has its last character removed with DEL, the
resulting empty search string no longer matches the previous line.
k. If readline reads a history file that begins with `#' (or the value of
the history comment character) and has enabled history timestamps, the history
entries are assumed to be delimited by timestamps. This allows multi-line
history entries.
l. Readline now throws an error if it parses a key binding without a terminating
`:' or whitespace.
-------------------------------------------------------------------------------
This is a terse description of the new features added to readline-6.3 since
the release of readline-6.2.
New Features in Readline
a. Readline is now more responsive to SIGHUP and other fatal signals when
reading input from the terminal or performing word completion but no
longer attempts to run any not-allowable functions from a signal handler
context.
b. There are new bindable commands to search the history for the string of
characters between the beginning of the line and the point
(history-substring-search-forward, history-substring-search-backward)
c. Readline allows quoted strings as the values of variables when setting
them with `set'. As a side effect, trailing spaces and tabs are ignored
when setting a string variable's value.
d. The history library creates a backup of the history file when writing it
and restores the backup on a write error.
e. New application-settable variable: rl_filename_stat_hook: a function called
with a filename before using it in a call to stat(2). Bash uses it to
expand shell variables so things like $HOME/Downloads have a slash
appended.
f. New bindable function `print-last-kbd-macro', prints the most-recently-
defined keyboard macro in a reusable format.
g. New user-settable variable `colored-stats', enables use of colored text
to denote file types when displaying possible completions (colored analog
of visible-stats).
h. New user-settable variable `keyseq-timout', acts as an inter-character
timeout when reading input or incremental search strings.
i. New application-callable function: rl_clear_history. Clears the history list
and frees all readline-associated private data.
j. New user-settable variable, show-mode-in-prompt, adds a characters to the
beginning of the prompt indicating the current editing mode.
k. New application-settable variable: rl_input_available_hook; function to be
called when readline detects there is data available on its input file
descriptor.
l. Readline calls an application-set event hook (rl_event_hook) after it gets
a signal while reading input (read returns -1/EINTR but readline does not
handle the signal immediately) to allow the application to handle or
otherwise note it.
m. If the user-settable variable `history-size' is set to a value less than
0, the history list size is unlimited.
n. New application-settable variable: rl_signal_event_hook; function that is
called when readline is reading terminal input and read(2) is interrupted
by a signal. Currently not called for SIGHUP or SIGTERM.
-------------------------------------------------------------------------------
This is a terse description of the new features added to readline-6.1 since
the release of readline-6.0.
New Features in Readline
a. New bindable function: menu-complete-backward.
b. In the vi insertion keymap, C-n is now bound to menu-complete by default,
and C-p to menu-complete-backward.
c. When in vi command mode, repeatedly hitting ESC now does nothing, even
when ESC introduces a bound key sequence. This is closer to how
historical vi behaves.
d. New bindable function: skip-csi-sequence. Can be used as a default to
consume key sequences generated by keys like Home and End without having
to bind all keys.
e. New application-settable function: rl_filename_rewrite_hook. Can be used
to rewite or modify filenames read from the file system before they are
compared to the word to be completed.
f. New bindable variable: skip-completed-text, active when completing in the
middle of a word. If enabled, it means that characters in the completion
that match characters in the remainder of the word are "skipped" rather
than inserted into the line.
g. The pre-readline-6.0 version of menu completion is available as
"old-menu-complete" for users who do not like the readline-6.0 version.
h. New bindable variable: echo-control-characters. If enabled, and the
tty ECHOCTL bit is set, controls the echoing of characters corresponding
to keyboard-generated signals.
i. New bindable variable: enable-meta-key. Controls whether or not readline
sends the smm/rmm sequences if the terminal indicates it has a meta key
that enables eight-bit characters.
-------------------------------------------------------------------------------
This is a terse description of the new features added to readline-6.0 since
the release of readline-5.2.
New Features in Readline
a. A new variable, rl_sort_completion_matches; allows applications to inhibit
match list sorting (but beware: some things don't work right if
applications do this).
b. A new variable, rl_completion_invoking_key; allows applications to discover
the key that invoked rl_complete or rl_menu_complete.
c. The functions rl_block_sigint and rl_release_sigint are now public and
available to calling applications who want to protect critical sections
(like redisplay).
d. The functions rl_save_state and rl_restore_state are now public and
available to calling applications; documented rest of readline's state
flag values.
e. A new user-settable variable, `history-size', allows setting the maximum
number of entries in the history list.
f. There is a new implementation of menu completion, with several improvements
over the old; the most notable improvement is a better `completions
browsing' mode.
g. The menu completion code now uses the rl_menu_completion_entry_function
variable, allowing applications to provide their own menu completion
generators.
h. There is support for replacing a prefix of a pathname with a `...' when
displaying possible completions. This is controllable by setting the
`completion-prefix-display-length' variable. Matches with a common prefix
longer than this value have the common prefix replaced with `...'.
i. There is a new `revert-all-at-newline' variable. If enabled, readline will
undo all outstanding changes to all history lines when `accept-line' is
executed.
-------------------------------------------------------------------------------
This is a terse description of the new features added to readline-5.2 since
the release of readline-5.1.
New Features in Readline
a. Calling applications can now set the keyboard timeout to 0, allowing
poll-like behavior.
b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
the default last-ditch startup file.
c. The history file reading functions now allow windows-like \r\n line
terminators.
-------------------------------------------------------------------------------
This is a terse description of the new features added to readline-5.1 since
the release of readline-5.0.
New Features in Readline
a. The key sequence sent by the keypad `delete' key is now automatically
bound to delete-char.
b. A negative argument to menu-complete now cycles backward through the
completion list.
c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
readline will bind the terminal special characters to their readline
equivalents when it's called (on by default).
d. New bindable command: vi-rubout. Saves deleted text for possible
reinsertion, as with any vi-mode `text modification' command; `X' is bound
to this in vi command mode.
e. If the rl_completion_query_items is set to a value < 0, readline never
asks the user whether or not to view the possible completions.
f. New application-callable auxiliary function, rl_variable_value, returns
a string corresponding to a readline variable's value.
g. When parsing inputrc files and variable binding commands, the parser
strips trailing whitespace from values assigned to boolean variables
before checking them.
h. A new external application-controllable variable that allows the LINES
and COLUMNS environment variables to set the window size regardless of
what the kernel returns.
-------------------------------------------------------------------------------
This is a terse description of the new features added to readline-5.0 since
the release of readline-4.3.
New Features in Readline
a. History expansion has a new `a' modifier equivalent to the `g' modifier
for compatibility with the BSD csh.
b. History expansion has a new `G' modifier equivalent to the BSD csh `g'
modifier, which performs a substitution once per word.
c. All non-incremental search operations may now undo the operation of
replacing the current line with the history line.
d. The text inserted by an `a' command in vi mode can be reinserted with
`.'.
e. New bindable variable, `show-all-if-unmodified'. If set, the readline
completer will list possible completions immediately if there is more
than one completion and partial completion cannot be performed.
f. There is a new application-callable `free_history_entry()' function.
g. History list entries now contain timestamp information; the history file
functions know how to read and write timestamp information associated
with each entry.
h. Four new key binding functions have been added:
rl_bind_key_if_unbound()
rl_bind_key_if_unbound_in_map()
rl_bind_keyseq_if_unbound()
rl_bind_keyseq_if_unbound_in_map()
i. New application variable, rl_completion_quote_character, set to any
quote character readline finds before it calls the application completion
function.
j. New application variable, rl_completion_suppress_quote, settable by an
application completion function. If set to non-zero, readline does not
attempt to append a closing quote to a completed word.
k. New application variable, rl_completion_found_quote, set to a non-zero
value if readline determines that the word to be completed is quoted.
Set before readline calls any application completion function.
l. New function hook, rl_completion_word_break_hook, called when readline
needs to break a line into words when completion is attempted. Allows
the word break characters to vary based on position in the line.
m. New bindable command: unix-filename-rubout. Does the same thing as
unix-word-rubout, but adds `/' to the set of word delimiters.
n. When listing completions, directories have a `/' appended if the
`mark-directories' option has been enabled.

Subject: Use of Readline
Reply-to: rms@gnu.org
I think Allbery's suggestion is a good one. So please add this text
in a suitable place. Please don't put it in the GPL itself; that
should be the same as the GPL everywhere else. Putting it in the
README and/or the documentation would be a good idea.
======================================================================
Our position on the use of Readline through a shared-library linking
mechanism is that there is no legal difference between shared-library
linking and static linking--either kind of linking combines various
modules into a single larger work. The conditions for using Readline
in a larger work are stated in section 3 of the GNU GPL.

dnl Macro to add for using GNU gettext.
dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
dnl default (if it is not specified or empty) is 'no-libtool'.
dnl INTLSYMBOL should be 'external' for packages with no intl directory,
dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
dnl If INTLSYMBOL is 'use-libtool', then a libtool library
dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
dnl depending on --{enable,disable}-{shared,static} and on the presence of
dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
dnl $(top_builddir)/intl/libintl.a will be created.
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
dnl implementations (in libc or libintl) without the ngettext() function
dnl will be ignored. If NEEDSYMBOL is specified and is
dnl 'need-formatstring-macros', then GNU gettext implementations that don't
dnl support the ISO C 99 formatstring macros will be ignored.
dnl INTLDIR is used to find the intl libraries. If empty,
dnl the value `$(top_builddir)/intl/' is used.
dnl
dnl The result of the configuration is one of three cases:
dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
dnl and used.
dnl Catalog format: GNU --> install in $(datadir)
dnl Catalog extension: .mo after installation, .gmo in source tree
dnl 2) GNU gettext has been found in the system's C library.
dnl Catalog format: GNU --> install in $(datadir)
dnl Catalog extension: .mo after installation, .gmo in source tree
dnl 3) No internationalization, always use English msgid.
dnl Catalog format: none
dnl Catalog extension: none
dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
dnl The use of .gmo is historical (it was needed to avoid overwriting the
dnl GNU format catalogs when building on a platform with an X/Open gettext),
dnl but we keep it in order not to force irrelevant filename changes on the
dnl maintainers.
