NAME Getopt::Long::Dump - Run a Getopt::Long-based script but only to dump the spec VERSION This document describes version 0.112 of Getopt::Long::Dump (from Perl distribution Getopt-Long-Dump), released on 2022-08-10. FUNCTIONS dump_getopt_long_script Usage: dump_getopt_long_script(%args) -> [$status_code, $reason, $payload, \%result_meta] Run a Getopt::Long-based script but only to dump the spec. This function runs a CLI script that uses "Getopt::Long" but monkey-patches beforehand so that "run()" will dump the object and then exit. The goal is to get the object without actually running the script. This can be used to gather information about the script and then generate documentation about it or do other things (e.g. "App::shcompgen" to generate a completion script for the original script). CLI script needs to use "Getopt::Long". This is detected currently by a simple regex. If script is not detected as using "Getopt::Long", status 412 is returned. Will return the "Getopt::Long" specification. This function is not exported by default, but exportable. Arguments ('*' denotes required arguments): * filename* => *str* Path to the script. * libs => *array[str]* Libraries to unshift to @INC when running script. * skip_detect => *bool* Returns an enveloped result (an array). First element ($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) ENVIRONMENT GETOPT_LONG_DUMP => bool Will be set to 1 when executing the script to be dumped. HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at . AUTHOR perlancar 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. COPYRIGHT AND LICENSE This software is copyright (c) 2022, 2016, 2015, 2014 by perlancar .
