Perinci::Sub::XCompletion::filename - Generate completion for filename


This document describes version 0.104 of Perinci::Sub::XCompletion::filename (from Perl distribution Perinci-Sub-XCompletion), released on 2023-03-01.


In argument specification of your Rinci function metadata:

 'x.completion' => 'filename',

Only complete with *.srt and *.SRT files:

 'x.completion' => ['filename' => {file_ext_filter => qr/^srt$/i}],


This completion passes arguments to Complete::File's complete_file, so see the documentation of that module for list of known arguments.




 gen_completion() -> [$status_code, $reason, $payload, \%result_meta]

This function is not exported.

No arguments.

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.

Return value: (any)

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.
