NAME

Acme::CPANModules::XSVersions - List of XS versions of Perl modules

VERSION

This document describes version 0.003 of Acme::CPANModules::XSVersions (from Perl distribution Acme-CPANModules-XSVersions), released on 2022-03-18.

SYNOPSIS

To install all XS versions of PP modules currently installed on your system:

 % perl -MAcme::CM::Get=XSVersions -MModule::Installed::Tiny=module_installed -E'for (@{$LIST->{entries}}) {
       next unless module_installed($_->{module}) || $_->{pp_module} && module_installed($_->{pp_module});
       say $_->{xs_module};
   }' | cpanm -n

(Note: To run the above snippet, you need to install Acme::CPANModules::XSVersions which you're reading right now, as well as Acme::CM::Get, Module::Installed::Tiny, and cpanm.)

DESCRIPTION

This list catalogs (pure-) Perl modules that have their XS counterparts ("fast versions"), usually in separate distributions so the installation of the XS version is optional. The two versions of the modules provide the same interface. When the two modules are different in interface, they are not listed here.

Usually authors use ::XS or _XS suffix for the XS version (for example, Type::Tiny is the PP/pure-perl version and Type::Tiny::XS is the XS version). Or sometimes the other way around is done, a module is an XS module and another with suffix ::PP or _PP is the PP version. And often a module like JSON is one that can automatically use the XS version (JSON::XS) when it's available or fallback to the PP version (JSON::PP).

Additions much welcome.

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

    % cpanmodules ls-entries XSVersions | cpanm -n

or Acme::CM::Get:

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

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, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
