Because it is based on PPI, it can do this without having to actually load the code. Currently it tests both the syntax of your code, and the use of explicit version dependencies such as "require 5.005". Future plans are to also add support for tracing module dependencies. Using "Perl::MinimumVersion" is dead simple, the synopsis pretty much covers it. METHODS new # Create the version checking object $object = Perl::MinimumVersion->new( $filename ); $object = Perl::MinimumVersion->new( \$source ); $object = Perl::MinimumVersion->new( $ppi_document ); The "new" constructor creates a new version checking object for a PPI::Document. You can also provide the document to be read as a file name, or as a "SCALAR" reference containing the code. Returns a new "Perl::MinimumVersion" object, or "undef" on error. Document The "Document" accessor can be used to get the PPI::Document object back out of the version checker. minimum_version The "minimum_version" method is the primary method for finding the minimum perl version required based on "all" factors in the document. At the present time, this is just syntax and explicit version checks, as Perl::Depends is not yet completed. Returns a version object, or "undef" on error. minimum_explicit_version The "minimum_explicit_version" method checks through Perl code for the use of explicit version dependencies such as. use 5.006; require 5.005_03; Although there is almost always only one of these in a file, if more than one are found, the highest version dependency will be returned. Returns a version object, false if no dependencies could be found, or "undef" on error. minimum_syntax_version $limit The "minimum_syntax_version" method will explicitly test only the Document's syntax to determine it's minimum version, to the extent that this is possible. It takes an optional parameter of a version object defining the the lowest known current value. For example, if it is already known that it must be 5.006 or higher, then you can provide a param of qv(5.006) and the method will not run any of the tests below this version. This should provide dramatic speed improvements for large and/or complex documents. The limitations of parsing Perl mean that this method may provide artifically low results, but should not artificially high results. For example, if "minimum_syntax_version" returned 5.006, you can be confident it will not run on anything lower, although there is a chance that during actual execution it may use some untestable feature that creates a dependency on a higher version. Returns a version object, false if no dependencies could be found, or "undef" on error. minimum_external_version WARNING: This method has not been implemented. Any attempted use will throw an exception The "minimum_external_version" examines code for dependencies on other external files, and recursively traverses the dependency tree applying the same tests to those files as it does to the original. Returns a "version" object, false if no dependencies could be found, or "undef" on error. version_markers This method returns a list of pairs in the form: ($version, \@markers) Each pair represents all the markers that could be found indicating that the version was the minimum needed version. @markers is an array of strings. Currently, these strings are not as clear as they might be, but this may be changed in the future. In other words: don't rely on them as specific identifiers. BUGS Perl::MinimumVersion does a reasonable job of catching the best-known explicit version dependencies. However it is exceedingly easy to add a new syntax check, so if you find something this is missing, copy and paste one of the existing 5 line checking functions, modify it to find what you want, and report it to rt.cpan.org, along with the version needed. I don't even need an entire diff... just the function and version. TO DO Write lots more version checkers - Perl 5.10 operators and language structures - Three-argument open Write the explicit version checker Write the recursive module descend stuff Check for more 5.12 features (currently only detecting "package NAME VERSION;", "...", and "use feature ':5.12'") SUPPORT All bugs should be filed via the CPAN bug tracker at For other issues, or commercial enhancement or support, contact the author.

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 Lesser 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.

=pod =head1 NAME Perl::MinimumVersion - Find a minimum required version of perl for Perl code =head1 SYNOPSIS # Create the version checking object $object = Perl::MinimumVersion->new( $filename ); $object = Perl::MinimumVersion->new( \$source ); $object = Perl::MinimumVersion->new( $ppi_document ); # Find the minimum version $version = $object->minimum_version; =head1 DESCRIPTION C takes Perl source code and calculates the minimum version of perl required to be able to run it. Because it is based on L, it can do this without having to actually load the code. Currently it tests both the syntax of your code, and the use of explicit version dependencies such as C. Future plans are to also add support for tracing module dependencies. Using C is dead simple, the synopsis pretty much covers it. =head1 METHODS =cut use 5.006; use strict; use warnings; use version (); use Carp (); use Exporter (); use List::Util qw(max first); use Params::Util ('_INSTANCE', '_CLASS'); use PPI::Util ('_Document'); use PPI (); use Perl::Critic::Utils 1.104 qw{ :classification :ppi }; use PPIx::Regexp; use Perl::MinimumVersion::Reason (); our ($VERSION, @ISA, @EXPORT_OK, %CHECKS, @CHECKS_RV ,%MATCHES); BEGIN { $VERSION = '1.32'; # Only needed for dev releases, comment out otherwise # $VERSION = eval $VERSION; # Export the PMV convenience constant @ISA = 'Exporter'; @EXPORT_OK = 'PMV'; # The primary list of version checks %CHECKS = ( _yada_yada_yada => version->new('5.012'), _pkg_name_version => version->new('5.012'), _postfix_when => version->new('5.012'), _perl_5010_pragmas => version->new('5.010'), _perl_5010_operators => version->new('5.010'), _perl_5010_magic => version->new('5.010'), # Various small things _bugfix_magic_errno => version->new('5.008.003'), _is_utf8 => version->new('5.008.001'), _unquoted_versions => version->new('5.008.001'), _perl_5008_pragmas => version->new('5.008'), _constant_hash => version->new('5.008'), _use_base_exporter => version->new('5.008'), _local_soft_reference => version->new('5.008'), _use_carp_version => version->new('5.008'), _open_temp => version->new('5.008'), _open_scalar => version->new('5.008'), # Included in 5.6.

You can also provide the document to be read as a file name, or as a C reference containing the code. Returns a new C object, or C on error. =cut sub new { my $class = ref $_[0] ? ref shift : shift; my $Document = _Document(shift) or return undef; my $default = _INSTANCE(shift, 'version') || version->new('5.004'); # Create the object my $self = bless { Document => $Document, # Checking limit and default minimum version. # Explicitly don't check below this version. default => $default, # Caches for resolved versions explicit => undef, syntax => undef, external => undef, }, $class; $self; } =pod =head2 Document The C accessor can be used to get the L object back out of the version checker. =cut sub Document { $_[0]->{Document} } ##################################################################### # Main Methods =pod =head2 minimum_version The C method is the primary method for finding the minimum perl version required based on C factors in the document. At the present time, this is just syntax and explicit version checks, as L is not yet completed.

Returns a L object, false if no dependencies could be found, or C on error. =cut sub minimum_explicit_version { my $self = _SELF(\@_) or return undef; my $reason = $self->minimum_explicit_reason(@_); return $reason ? $reason->version : $reason; } sub minimum_explicit_reason { my $self = _SELF(\@_) or return undef; unless ( defined $self->{explicit} ) { $self->{explicit} = $self->_minimum_explicit_version; } return $self->{explicit}; } sub _minimum_explicit_version { my $self = shift or return undef; my $explicit = $self->Document->find( sub { $_[1]->isa('PPI::Statement::Include') or return ''; $_[1]->version or return ''; 1; } ); return $explicit unless $explicit; # Find the highest version my $max = undef; my $element = undef; foreach my $include ( @$explicit ) { my $version = version->new($include->version); if ( not $element or $version > $max ) { $max = $version; $element = $include; } } return Perl::MinimumVersion::Reason->new( rule => 'explicit', version => $max, element => $element, ); } =pod =head2 minimum_syntax_version $limit The C method will explicitly test only the Document's syntax to determine it's minimum version, to the extent that this is possible. It takes an optional parameter of a L object defining the the lowest known current value. For example, if it is already known that it must be 5.006 or higher, then you can provide a param of qv(5.006) and the method will not run any of the tests below this version. This should provide dramatic speed improvements for large and/or complex documents. The limitations of parsing Perl mean that this method may provide artifically low results, but should not artificially high results. For example, if C returned 5.006, you can be confident it will not run on anything lower, although there is a chance that during actual execution it may use some untestable feature that creates a dependency on a higher version. Returns a L object, false if no dependencies could be found, or C on error. =cut sub minimum_syntax_version { my $self = _SELF(\@_) or return undef; my $reason = $self->minimum_syntax_reason(@_); return $reason ? $reason->version : $reason; } sub minimum_syntax_reason { my $self = _SELF(\@_) or return undef; my $limit = shift; if ( defined $limit and not _INSTANCE($limit, 'version') ) { $limit = version->new("$limit"); } if ( defined $self->{syntax} ) { if ( !defined($limit) or $self->{syntax}->version >= $limit ) { # Previously discovered minimum is what they want return $self->{syntax}; } # Rather than return a value BELOW their filter, # which they would not be expecting, return false. return ''; } # Look for the value my $syntax = $self->_minimum_syntax_version( $limit ); # If we found a value, it will be stable, cache it. # If we did NOT, don't cache as subsequent runs without # the filter may find a version. if ( $syntax ) { $self->{syntax} = $syntax; return $self->{syntax}; } return ''; } #for Perl::Critic::Policy::Compatibility::PerlMinimumVersionAndWhy sub _set_checks2skip { my $self = shift; my $list = shift; $self->{_checks2skip} = $list; } sub _set_collect_all_reasons { my $self = shift; my $value = shift; $value = 1 unless defined $value; $self->{_collect_all_reasons} = $value; } sub _minimum_syntax_version { my $self = shift; my $filter = shift || $self->{default}; my %checks2skip; @checks2skip{ @{ $self->{_checks2skip} || [] } } = (); my %rv_result; my $current_reason; foreach my $rule ( @CHECKS_RV ) { next if exists $checks2skip{$rule}; my ($v, $obj) = $self->$rule(); $v = version->new($v); if ( $v > $filter ) { $current_reason = Perl::MinimumVersion::Reason->new( rule => $rule, version => $v, element => _INSTANCE($obj, 'PPI::Element'), ); if ($self->{_collect_all_reasons}) { push @{ $self->{_all_reasons} }, $current_reason; } else { $filter = $v; } } } # Always check in descending version order. # By doing it this way, the version of the first check that matches # is also the version of the document as a whole. my @rules = sort { $CHECKS{$b} <=> $CHECKS{$a} } grep { not(exists $checks2skip{$_}) and $CHECKS{$_} > $filter } keys %CHECKS; foreach my $rule ( @rules ) { my $result = $self->$rule() or next; # Create the result object my $reason = Perl::MinimumVersion::Reason->new( rule => $rule, version => $CHECKS{$rule}, element => _INSTANCE($result, 'PPI::Element'), ); if ($self->{_collect_all_reasons}) { push @{ $self->{_all_reasons} }, $current_reason; } else { return $reason; } } # Found nothing of interest return $current_reason || ''; } =pod =head2 minimum_external_version B The C examines code for dependencies on other external files, and recursively traverses the dependency tree applying the same tests to those files as it does to the original.
