get-regexp-pattern-pattern - Get a Regexp::Pattern::* pattern
This document describes version 0.008 of get-regexp-pattern-pattern (from Perl distribution App-RegexpPatternUtils), released on 2022-05-08.
Usage:
% get-regexp-pattern-pattern [--format=name|--json] [(--gen-arg key=s)+] [--(no)naked-res] [--page-result[=program]|--view-result[=program]] [--gen-args-json=json|(-A key=s)+] -- <pattern>
See examples in the "EXAMPLES" section.
* marks required options.
*
Supply generator arguments.
If pattern is a dynamic pattern (generated on-demand) and the generator requires some arguments, you can supply them here.
Each value is a name-value pair, use key=value syntax. Can be specified multiple times.
Supply generator arguments (JSON-encoded).
See --gen-arg.
--gen-arg
Name of pattern, with module prefix but without the 'Regexp::Pattern'.
Can also be specified as the 1st command-line argument.
Choose output format, e.g. json, text.
Default value:
undef
Set output format to json.
When outputing as JSON, strip result envelope.
0
By default, when outputing as JSON, the full enveloped result is returned, e.g.:
[200,"OK",[1,2,3],{"func.extra"=>4}]
The reason is so you can get the status (1st element), status message (2nd element) as well as result metadata/extra result (4th element) instead of just the result (3rd element). However, sometimes you want just the result, e.g. when you want to pipe the result for more post-processing. In this case you can use `--naked-res` so you just get:
[1,2,3]
Filter output through a pager.
View output using a viewer.
Display help message and exit.
Display program's version and exit.
This script has shell tab completion capability with support for several shells.
To activate bash completion for this script, put:
complete -C get-regexp-pattern-pattern get-regexp-pattern-pattern
in your bash startup (e.g. ~/.bashrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.
It is recommended, however, that you install modules using cpanm-shcompgen which can activate shell completion for scripts immediately.
To activate tcsh completion for this script, put:
complete get-regexp-pattern-pattern 'p/*/`get-regexp-pattern-pattern`/'
in your tcsh startup (e.g. ~/.tcshrc). Your next shell session will then recognize tab completion for the command. Or, you can also directly execute the line above in your shell to activate immediately.
It is also recommended to install shcompgen (see above).
For fish and zsh, install shcompgen as described above.

Generate variant A of Example::re3:
% get-regexp-pattern-pattern Example::re3 --gen-arg 'variant=A' (?^:\d{3}-\d{3})
Generate variant B of Example::re3:
% get-regexp-pattern-pattern Example::re3 --gen-arg 'variant=B' (?^:\d{3}-\d{2}-\d{5})

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.
