(Thanks to Bill Nugent for the bug report and initial patch.) - Removed unused ExtUtils::MakeMaker::bytes, which doesn't exist anymore anyway. (Thanks to Slaven Rezić for the bug report.) Version 0.1622: Wed Jul 16 2008 - Updated to the latest version of Module::Install - Removed auto-install for better compatibility with CPAN and others - Moved hosting to Google Code Version 0.1621: - Improved compatibility with versions of Perl older than 5.6.0, by replacing "use bytes" with "use ExtUtils::MakeMaker::bytes". (Thanks to for the bug report.) - Fixed test case error reporting for tests that fail to fork. (Thanks to for the test failure report.) - Fixed unexpected success of binmode_bug.t test on Windows 2000. (Thanks to Max Maischein for the bug report.) - Fixed a bug in stdin_tell_bug.t. (Thanks to Max Maischein for the bug report.) Version 0.1620: Tue Dec 21 2004 - Fixed version numbers, which were incompatible with some modules. (Thanks to Tassilo von Parseval for the bug report) - Switched to Test::More for better test reporting - Removed the use of the "English" module to work around a bug that exists in some versions of Perl. See http://groups.google.com/groups?th=e3483b06a956030e for more info. (Thanks to Jim Longino for the bug report.) Version 0.16.1: Thu Sep 16 2004 - Added missing inc/ dependency Version 0.16.0: Wed Sep 15 2004 - Fixed stdin_tell_bug.t so that it's more platform-dependent. (Martin Thurn reports that Solaris 2.8 returns 0 instead of -1). - Added filehandle-specific input_record_separator capability (Feature suggestion by David Muir Sharnoff ) - Changed Makefile.PL to use Module::Install Version 0.15: - Switched from WeakRef to Scalar::Util, which is included in recent versions of Perl. (Thanks to Joey Hess for the suggestion and patch.) - Fixed a bug involving pipes and tell(), where tell() would cause following operations to fail. (Thanks to Karol Szafranski for the bug report.) - Added new_from_fd support (Thanks to Karol Szafranski for the bug report.) - Fixed a bug in which <$fh> would always behave as if called in a list context after the first such call. Version 0.14: - Fixed an incompatibility with perl 5.6.1 and Data::Dumper. (Thanks to Jason Brunette for the bug report and patch.) - Fixed a bug in the seek.t test case which would cause failure on Windows (Thanks to rurban@x-ray.at for the bug report.) - Fixed a memory leak. (Thanks to Jason Brunette for taking the time to not only file the bug report, but also do a lot of work to track down the cause.) For now I'm using WeakRef to deal with circular references. If anyone can tell me how to get rid of them entirely I'd be grateful. See the discussion here: https://sourceforge.net/tracker/index.php?func=detail&aid=892742&group_id=93038&atid=602891 Version 0.13: - Added detection for a case in which a Perl bug will be exercised on Windows. Also added a test case (binmode_bug.t) to demonstrate it. See the BUGS section of the documentation. - Added a couple new test cases. Version 0.12: - Changed the filehandle detection scheme so that filehandles created using Symbol::gensym would be detected correctly. (Thanks to Tassilo von Parseval for finding the bug) - Fixed a bug in getline and getlines which would cause the routines to not return undef at the end of the file. (Thanks to Tassilo von Parseval for finding the bug) - Fixed a potential bug in seek which would cause the module to not intercept the seek call following a previous seek call with an invalid whence parameter. Version 0.11: - Fixed uninitialized value warnings - Create SourceForge project Version 0.10: - Initial version FileHandle-Unget-0.1623/inc/0000755000076500000240000000000011246542141014612 5ustar coppitstaffFileHandle-Unget-0.1623/inc/Module/0000755000076500000240000000000011246542141016037 5ustar coppitstaffFileHandle-Unget-0.1623/inc/Module/Install/0000755000076500000240000000000011246542141017445 5ustar coppitstaffFileHandle-Unget-0.1623/inc/Module/Install/Base.pm0000644000076500000240000000176611246540005020664 0ustar coppitstaff#line 1 package Module::Install::Base; use strict 'vars'; use vars qw{$VERSION}; BEGIN { $VERSION = '0.91'; } # Suspend handler for "redefined" warnings BEGIN { my $w = $SIG{__WARN__}; $SIG{__WARN__} = sub { $w }; } #line 42 sub new { my $class = shift; unless ( defined &{"${class}::call"} ) { *{"${class}::call"} = sub { shift->_top->call(@_) }; } unless ( defined &{"${class}::load"} ) { *{"${class}::load"} = sub { shift->_top->load(@_) }; } bless { @_ }, $class; } #line 61 sub AUTOLOAD { local $@; my $func = eval { shift->_top->autoload } or return; goto &$func; } #line 75 sub _top { $_[0]->{_top}; } #line 90 sub admin { $_[0]->_top->{admin} or Module::Install::Base::FakeAdmin->new; } #line 106 sub is_admin { $_[0]->admin->VERSION; } sub DESTROY {} package Module::Install::Base::FakeAdmin; my $fake; sub new { $fake ||= bless(\@_, $_[0]); } sub AUTOLOAD {} sub DESTROY {} # Restore warning handler BEGIN { $SIG{__WARN__} = $SIG{__WARN__}->(); } 1; #line 154 FileHandle-Unget-0.1623/inc/Module/Install/Can.pm0000644000076500000240000000333311246540005020503 0ustar coppitstaff#line 1 package Module::Install::Can; use strict; use Config (); use File::Spec (); use ExtUtils::MakeMaker (); use Module::Install::Base (); use vars qw{$VERSION @ISA $ISCORE}; BEGIN { $VERSION = '0.91'; @ISA = 'Module::Install::Base'; $ISCORE = 1; } # check if we can load some module ### Upgrade this to not have to load the module if possible sub can_use { my ($self, $mod, $ver) = @_; $mod =~ s{::|\\}{/}g; $mod .= '.pm' unless $mod =~ /\.pm$/i; my $pkg = $mod; $pkg =~ s{/}{::}g; $pkg =~ s{\.pm$}{}i; local $@; eval { require $mod; $pkg->VERSION($ver || 0); 1 }; } # check if we can run some command sub can_run { my ($self, $cmd) = @_; my $_cmd = $cmd; return $_cmd if (-x $_cmd or $_cmd = MM->maybe_command($_cmd)); for my $dir ((split /$Config::Config{path_sep}/, $ENV{PATH}), '.') { next if $dir eq ''; my $abs = File::Spec->catfile($dir, $_[1]); return $abs if (-x $abs or $abs = MM->maybe_command($abs)); } return; } # can we locate a (the) C compiler sub can_cc { my $self = shift; my @chunks = split(/ /, $Config::Config{cc}) or return; # $Config{cc} may contain args; try to find out the program part while (@chunks) { return $self->can_run("@chunks") || (pop(@chunks), next); } return; } # Fix Cygwin bug on maybe_command(); if ( $^O eq 'cygwin' ) { require ExtUtils::MM_Cygwin; require ExtUtils::MM_Win32; if ( ! defined(&ExtUtils::MM_Cygwin::maybe_command) ) { *ExtUtils::MM_Cygwin::maybe_command = sub { my ($self, $file) = @_; if ($file =~ m{^/cygdrive/}i and ExtUtils::MM_Win32->can('maybe_command')) { ExtUtils::MM_Win32->maybe_command($file); } else { ExtUtils::MM_Unix->maybe_command($file); } } } } 1; __END__ #line 156 FileHandle-Unget-0.1623/inc/Module/Install/Fetch.pm0000644000076500000240000000462711246540005021042 0ustar coppitstaff#line 1 package Module::Install::Fetch; use strict; use Module::Install::Base (); use vars qw{$VERSION @ISA $ISCORE}; BEGIN { $VERSION = '0.91'; @ISA = 'Module::Install::Base'; $ISCORE = 1; } sub get_file { my ($self, %args) = @_; my ($scheme, $host, $path, $file) = $args{url} =~ m|^(\w+)://([^/]+)(.+)/(.+)| or return; if ( $scheme eq 'http' and ! eval { require LWP::Simple; 1 } ) { $args{url} = $args{ftp_url} or (warn("LWP support unavailable!\n"), return); ($scheme, $host, $path, $file) = $args{url} =~ m|^(\w+)://([^/]+)(.+)/(.+)| or return; } $|++; print "Fetching '$file' from $host...

It also provides ungets to unget a string. This module is useful if the filehandle refers to a stream for which you can't just C backwards. Some operating systems support multi-byte C, but this is not guaranteed. Use this module if you want a portable solution. In addition, on some operating systems, eof() will not be reset if you ungetc after having read to the end of the file. NOTE: Using C with C and other buffering functions is still a bad idea. =head1 METHODS The methods for this package are the same as those of the FileHandle package, with the following exceptions. =over 4 =item new ( ARGS ) The constructor is exactly the same as that of FileHandle, except that you can also call it with an existing IO::Handle object to "attach" unget semantics to a pre-existing handle. =item $fh->ungetc ( ORD ) Pushes a character with the given ordinal value back onto the given handle's input stream. This method can be called more than once in a row to put multiple values back on the stream. Memory usage is equal to the total number of bytes pushed back. =item $fh->ungets ( BUF ) Pushes a buffer back onto the given handle's input stream. This method can be called more than once in a row to put multiple buffers of characters back on the stream. Memory usage is equal to the total number of bytes pushed back. The buffer is not processed in any way--managing end-of-line characters and whatnot is your responsibility. =item $fh->buffer ( [BUF] ) Get or set the pushback buffer directly. =item $fh->input_record_separator ( STRING ) Get or set the per-filehandle input record separator. After it is called, the input record separator for the filehandle is independent of the global $/. Until this method is called (and after clear_input_record_separator is called) the global $/ is used. =item $fh->clear_input_record_separator () Clear the per-filehandle input record separator. This removes the per-filehandle input record separator semantics, reverting the filehandle to the normal global $/ semantics. =item tell ( $fh ) C returns the actual file position minus the length of the unget buffer. If you read three bytes, then unget three bytes, C will report a file position of 0. Everything works as expected if you are careful to unget the exact same bytes which you read. However, things get tricky if you unget different bytes. First, the next bytes you read won't be the actual bytes on the filehandle at the position indicated by C. Second, C will return a negative number if you unget more bytes than you read. (This can be problematic since this function returns -1 on error.) =item seek ( $fh, [POSITION], [WHENCE] ) C defaults to the standard seek if possible, clearing the unget buffer if it succeeds. If the standard seek fails, then C will attempt to seek within the unget buffer. Note that in this case, you will not be able to seek backward--FileHandle::Unget will only save a buffer for the next bytes to be read. For example, let's say you read 10 bytes from a pipe, then unget the 10 bytes. If you seek 5 bytes forward, you won't be able to read the first five bytes. (Otherwise this module would have to keep around a lot of probably useless data!) =back =head1 COMPATIBILITY To test that this module is indeed a drop-in replacement for FileHandle, the following modules were modified to use FileHandle::Unget, and tested using "make test". They have all passed. =head1 BUGS There is a bug in Perl on Windows that is exposed if you open a stream, then check for eof, then call binmode. For example: # First line # Second line open FH, "$^X -e \"open F, '$0';binmode STDOUT;print \" |"; eof(FH); binmode(FH); print "First line:", scalar , "\n"; print "Second line:", scalar , "\n"; close FH; One solution is to make sure that you only call binmode immediately after opening the filehandle. I'm not aware of any workaround for this bug that FileHandle::Unget could implement. However, the module does detect this situation and prints a warning.

See the file "LICENSE" for more information. =head1 SEE ALSO Mail::Mbox::MessageParser for an example of how to use this package. =cut FileHandle-Unget-0.1623/LICENSE0000644000076500000240000004313111037110762015046 0ustar coppitstaff GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) 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 this service 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 make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. 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. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), 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 distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the 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 a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11.

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 convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

It supports an ungetc(ORD) which can be called more than once in a row, and an ungets(SCALAR) which places a string of bytes back on the input. MODULE DEPENDENCIES To use this module, you will need to install: - Scalar::Util To test this module, you will need to install: - Test::More - File::Spec INSTALLATION To install this package, change to the directory where you unarchived this distribution and type the following: perl Makefile.PL make make test make install You can install this package into a non-default location by appending one of the following to the "perl Makefile.PL" command: - "PREFIX=/installation/path" (for installation into a custom location), - "INSTALLDIRS=site" (for installation into site-specific Perl directories) - "INSTALLDIRS=perl" (for installation into standard Perl directories). If you make the installation into your own directory, then remember that you must tell perl where to search for modules before trying to 'use' them. For example: use lib '/home/userid/lib'; use FileHandle::Unget; If make test fails, please see the INSTALLATION PROBLEMS section below. INSTALLATION PROBLEMS If you get warnings about weak references not being implemented in your version of Perl, try upgrading your installation of Scalar::Util. If "make test" fails, run make test TEST_VERBOSE=1 and see which test(s) are failing. Please email the results to the address below, or submit a bug report on the project website as described in the section REPORTING BUGS below. For other bugs, see the section REPORTING BUGS below. SECURITY NOTE On Windows, this module will use a temporary file to decompress a file handle when necessary. This could pose a security risk. DOCUMENTATION Just "perldoc FileHandle::Unget". After installation on Unix systems, you can also do "man FileHandle::Unget".
