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. The distribution comes with a script called perlver, which is the easiest way to run "Perl::MinimumVersion" on your code: % perlver lib/Foo/Bar.pm See the documentation for perlver for more details. 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 $limit The "minimum_syntax_version" method will explicitly test only the Document's syntax to determine it's minimum version, to the extent that this is possible. It takes an optional parameter of a version object defining the lowest known current value. For example, if it is already known that it must be 5.006 or higher, then you can provide a param of qv(5.006) and the method will not run any of the tests below this version. This should provide dramatic speed improvements for large and/or complex documents. The limitations of parsing Perl mean that this method may provide artificially low results, but should not artificially high results. For example, if "minimum_syntax_version" returned 5.006, you can be confident it will not run on anything lower, although there is a chance that during actual execution it may use some untestable feature that creates a dependency on a higher version. Returns a version object, false if no dependencies could be found, or "undef" on error. minimum_external_version WARNING: This method has not been implemented. Any attempted use will throw an exception The "minimum_external_version" examines code for dependencies on other external files, and recursively traverses the dependency tree applying the same tests to those files as it does to the original. Returns a "version" object, false if no dependencies could be found, or "undef" on error. version_markers This method returns a list of pairs in the form: ($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 _while_readdir for postfix while without brackets 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.

RT#98262 from pagenyon++. - Added mention of Perl::MinimumVersion::Fast to SEE ALSO. 1.37 2014-05-11 - Removed the check for "stacked labels" that I added in 1.36, as it appears that I misinterpreted what the 5.14 change was, and broke at least one dist. Commented out the check in MinimumVersion.pm, and the specific subtests. Apologies to HMBRAND and all others affected - The way I was comparing versions in one of the new tests in 1.36 wasn't portable across old versions of Perl. Thanks to Paul Howarth for RT#95528. 1.36 2014-05-09 - CHECK block requires 5.6.2 - UNITCHECK block requires 5.10.0 - Stacked labels on the same statement requires 5.14.0 1.35 2014-05-02 - 'state' requires perl 5.10.0, even if you don't also see "use feature 'state'", because you can also write "use 5.010" to enable 'state'. RT#67626 - Dropped the rule that said "use base 'Exporter'" should make a dependency on Perl 5.008+ RT#89173 - Improved the fix for RT#95023. Thanks again to Paul Howarth. 1.34 2014-04-24 - The perlver script wasn't getting installed, because it's in a script/ directory. RT#95023, fix from ETHER. - t/02_main.t was failing on older versions of perl, because a min version is getting reported as '5.01301' on Perl 5.010 and later, but as '5.013010' on earlier Perls. RT#95023.

Preamble The license agreements of most software companies try to keep users at the mercy of those companies. By contrast, our 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. The General Public License applies to the Free Software Foundation's software and to any other program whose authors commit to using it. You can use it for your programs, too. When we speak of free software, we are referring to freedom, not price. Specifically, the General Public License is designed to make sure that you have the freedom to give away or sell copies of free software, 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 a 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 tell them 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. 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 Agreement 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 work containing the Program or a portion of it, either verbatim or with modifications. Each licensee is addressed as "you". 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 General Public License and to the absence of any warranty; and give any other recipients of the Program a copy of this General Public License along with the Program. You may charge a fee for the physical act of transferring a copy. 2. You may modify your copy or copies of the Program or any portion of it, and copy and distribute such modifications under the terms of Paragraph 1 above, provided that you also do the following: a) cause the modified files to carry prominent notices stating that you changed the files and the date of any change; and b) cause the whole of any work that you distribute or publish, that in whole or in part contains the Program or any part thereof, either with or without modifications, to be licensed at no charge to all third parties under the terms of this General Public License (except that you may choose to grant warranty protection to some or all third parties, at your option). c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the simplest and most usual 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 General Public License. d) 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. Mere aggregation of another independent work with the Program (or its derivative) on a volume of a storage or distribution medium does not bring the other work under the scope of these terms. 3. You may copy and distribute the Program (or a portion or derivative of it, under Paragraph 2) in object code or executable form under the terms of Paragraphs 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 Paragraphs 1 and 2 above; or, b) accompany it with a written offer, valid for at least three years, to give any third party free (except for a nominal charge for the cost of distribution) a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Paragraphs 1 and 2 above; or, c) accompany it with the information you received as to where the corresponding source code may be obtained. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form alone.) Source code for a work means the preferred form of the work for making modifications to it. For an executable file, complete source code means all the source code for all modules it contains; but, as a special exception, it need not include source code for modules which are standard libraries that accompany the operating system on which the executable file runs, or for standard header files or definitions files that accompany that operating system. 4. You may not copy, modify, sublicense, distribute or transfer the Program except as expressly provided under this General Public License. Any attempt otherwise to copy, modify, sublicense, distribute or transfer the Program is void, and will automatically terminate your rights to use the Program under this License. However, parties who have received copies, or rights to use copies, from you under this General Public License will not have their licenses terminated so long as such parties remain in full compliance. 5. By copying, distributing or modifying 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. 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. 7. 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 the 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 the license, you may choose any version ever published by the Free Software Foundation. 8. 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 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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. 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE 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. END OF TERMS AND CONDITIONS Appendix: 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 humanity, 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. Copyright (C) 19yy 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 1, 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, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19xx name of author Gnomovision 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, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary.

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.

It takes an optional parameter of a L object defining 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 artificially 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.
