Perinci::CmdLine::Dump - Run a Perinci::CmdLine-based script but only to dump the object
This document describes version 0.120 of Perinci::CmdLine::Dump (from Perl distribution Perinci-CmdLine-Dump), released on 2018-11-22.
dump_pericmd_script(%args) -> [status, msg, payload, 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::Base 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 (e.g.
Pod::Weaver::Plugin::Rinci to insert POD sections based on information from the Rinci metadata of the function used by the script) or do other things (e.g.
App::shcompgen to 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::CmdLine object 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.meta in 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) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
Return value: (any)
