NAME

Acme::CPANModules::OneAndTwoDecimalDigitsVersionTrap - List of CPAN distributions which have been trapped by the one- and two decimal digits versioning scheme

VERSION

This document describes version 0.003 of Acme::CPANModules::OneAndTwoDecimalDigitsVersionTrap (from Perl distribution Acme-CPANModules-OneAndTwoDecimalDigitsVersionTrap), released on 2023-10-29.

DESCRIPTION

The x.y and x.yy versioning scheme used in Perl distribution has a trap: when you release a new version by incrementing the patchlevel part into x.y.z and x.yy.z, the new version number will be less than x.y and x.yy because x.y and x.yy will numify to x.y00 and x.yy0 respectivey; while x.y.z and x.yy.z will numify to x.00y.z and x.0yy, respectively.

So if you release Acme-MyDist-0.1 (numifies to 0.100000) then Acme-MyDist-0.1.1 (0.001001), or Acme-MyDist-0.01 (0.010000) then Acme-MyDist-0.01.1 (0.001001), PAUSE will refuse to index your new version because of "decreasing version number."

This does not happen when you release Acme-MyDist-0.001 (0.001000) and then Acme-MyDist-0.001.1 (0.001001).

This thing is peculiar to Perl, and is not intuitive. Consequently, sometimes CPAN authors are not familiar with this and thus have fallen into this trap.

This list chronicles distributions which have been trapped by this.

ACME::CPANMODULES ENTRIES

Validate::Simple

From 0.01 to 0.01.1.

Author: ANDREIP

Author's comment in ChangeLog: "Change version properly."

Bencher

From 0.46 to 0.46.1.

Author's comment in ChangeLog: "This version number is broken because 0.46 > 0.46.1 because 0.46 normalizes to 0.460.000 while 0.46.1 is 0.046.100. This has happened a few times to me in other distributions too, so perhaps it's time to consider switching to a 3-digit minor version."

FAQ

What is an Acme::CPANModules::* module?

An Acme::CPANModules::* module, like this module, contains just a list of module names that share a common characteristics. It is a way to categorize modules and document CPAN. See Acme::CPANModules for more details.

What are ways to use this Acme::CPANModules module?

Aside from reading this Acme::CPANModules module's POD documentation, you can install all the listed modules (entries) using cpanm-cpanmodules script (from App::cpanm::cpanmodules distribution):

% cpanm-cpanmodules -n OneAndTwoDecimalDigitsVersionTrap

Alternatively you can use the cpanmodules CLI (from App::cpanmodules distribution):

% cpanmodules ls-entries OneAndTwoDecimalDigitsVersionTrap | cpanm -n

or Acme::CM::Get:

% perl -MAcme::CM::Get=OneAndTwoDecimalDigitsVersionTrap -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n

or directly:

% perl -MAcme::CPANModules::OneAndTwoDecimalDigitsVersionTrap -E'say $_->{module} for @{ $Acme::CPANModules::OneAndTwoDecimalDigitsVersionTrap::LIST->{entries} }' | cpanm -n

This Acme::CPANModules module also helps lcpan produce a more meaningful result for lcpan related-mods command when it comes to finding related modules for the modules listed in this Acme::CPANModules module. See App::lcpan::Cmd::related_mods for more details on how "related modules" are found.

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

% prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
