NAME

Acme::CPANModules::GettingTempDir - List of ways of getting system-wide temporary directory in a portable way

VERSION

This document describes version 0.002 of Acme::CPANModules::GettingTempDir (from Perl distribution Acme-CPANModules-GettingTempDir), released on 2023-10-29.

DESCRIPTION

There's the good ol' File::Spec which has a tmpdir function. On Unix it looks at TMPDIR environment variable before falling back to /tmp. File::Temp uses this for its tempdir when a template is not specified.

Then there's File::Util::Tempdir which tries a little harder. On Unix, its get_tempdir will look at TMPDIR, then also TEMPDIR, TMP, TEMP. If none of those are set, it will return the first existing directory from the list: /tmp, /var/tmp. If everything fails, will die.

File::Util::Tempdir also provides get_user_tempdir which returns a user-private temporary directory, which can be useful if you want to create temporary file with predetermined names. It will return temporary directory pointed by XDG_RUNTIME_DIR (e.g. /run/user/1000) or, if unavailable, will create a subdirectory under the world-writable temporary directory (e.g. /tmp/1000).

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 GettingTempDir

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

    % cpanmodules ls-entries GettingTempDir | cpanm -n

or Acme::CM::Get:

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

or directly:

    % perl -MAcme::CPANModules::GettingTempDir -E'say $_->{module} for @{ $Acme::CPANModules::GettingTempDir::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.
