Perinci::CmdLine::Dump - Run a Perinci::CmdLine-based script but only to dump the object
This document describes version 0.121 of Perinci::CmdLine::Dump (from Perl distribution Perinci-CmdLine-Dump), released on 2022-01-16.
dump_pericmd_script(%args) -> [$status_code, $reason, $payload, \%result_meta]
Run a Perinci::CmdLine-based script but only to dump the object.
This function runs a CLI script that uses
Perinci::CmdLine(or its variant
Perinci::CmdLine::Any) but monkey-patches
Perinci::CmdLine::Basebeforehand so that
run()will dump the object and then exit. The goal is to get the object without actually running the script.
This can be used to gather information about the script and then generate documentation about it (e.g.
Pod::Weaver::Plugin::Rincito insert POD sections based on information from the Rinci metadata of the function used by the script) or do other things (e.g.
App::shcompgento generate a completion script for the original script).
CLI script needs to use
Perinci::CmdLine. This is detected currently by a simple regex. If script is not detected as using
Perinci::CmdLine, status 412 is returned.
Will return the
Perinci::CmdLineobject dump. In addition to that, if detected that script refers to function URL
/main(which might mean that function metadata is embedded in the script itself and not in a separate module), will also dump the target function's metadata in
func.metain this function's result metadata.
This function is not exported by default, but exportable.
Arguments ('*' denotes required arguments):
filename* => str
Path to the script.
libs => array[str]
Libraries to unshift to @INC when running script.
method => str
patchmethod is using monkey-patching to replace run() with a routine that dumps the object and exit. This has a disadvantage of exiting too early, for example some attributes like
common_optsis filled during run(). Another method is
self-dumpthat requires Perinci::CmdLine::Lite version 1.73 or later.
The default is to use
skip_detect => bool
Returns an enveloped result (an array).
First element ($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)

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.
