Perinci::CmdLine::Plugin::Run::Completion - Shell completion mode


This document describes version 1.928 of Perinci::CmdLine::Plugin::Run::Completion (from Perl distribution Perinci-CmdLine-Lite), released on 2022-11-24.


A Run:: plugin is the main plugin that runs at the run event, which is fired by Perinci::CmdLine's run() method.

Multiple Run::* plugins can be registered at the run event, but only one will actually run because they return 201 code which instruct Perinci::CmdLine to end the event early.

The Run::Completion plugin handles the tab completion. It only runs if one of the environment variables (like COMP_LINE in bash) signals that shell completion is requested. Otherwise the handler declines.

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.
