NAME
App::RegexpPatternUtils - CLI utilities related to Regexp::Pattern
VERSION
This document describes version 0.008 of App::RegexpPatternUtils (from Perl distribution App-RegexpPatternUtils), released on 2022-05-08.
SYNOPSIS
DESCRIPTION
This distribution includes several utilities related to Regexp::Pattern:
FUNCTIONS
get_regexp_pattern_pattern
Usage:
get_regexp_pattern_pattern(
%args
) -> [
$status_code
,
$reason
,
$payload
, \
%result_meta
]
Get a Regexp::Pattern::* pattern.
Examples:
Example #1:
get_regexp_pattern_pattern(
pattern
=>
"YouTube/video_id"
);
# -> [200, "OK", "(?^:[A-Za-z0-9_-]{11})", {}]
Generate variant A of Example::re3:
get_regexp_pattern_pattern(
pattern
=>
"Example::re3"
,
gen_args
=> {
variant
=>
"A"
});
Result:
[200,
"OK"
,
"(?^:\\d{3}-\\d{3})"
, {}]
Generate variant B of Example::re3:
get_regexp_pattern_pattern(
pattern
=>
"Example::re3"
,
gen_args
=> {
variant
=>
"B"
});
Result:
[200,
"OK"
,
"(?^:\\d{3}-\\d{2}-\\d{5})"
, {}]
This function is not exported.
Arguments ('*' denotes required arguments):
gen_args => hash
Supply generator arguments.
If pattern is a dynamic pattern (generated on-demand) and the generator requires some arguments, you can supply them here.
pattern* => regexppattern::name
Name of pattern, with module prefix but without the 'Regexp::Pattern'.
Returns an enveloped result (an array).
First element ($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)
list_regexp_pattern_modules
Usage:
list_regexp_pattern_modules() -> [
$status_code
,
$reason
,
$payload
, \
%result_meta
]
List all installed Regexp::Pattern::* modules.
This function is not exported.
No arguments.
Returns an enveloped result (an array).
First element ($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)
match_with_regexp_pattern
Usage:
match_with_regexp_pattern(
%args
) -> [
$status_code
,
$reason
,
$payload
, \
%result_meta
]
Match a string against a Regexp::Pattern pattern.
Examples:
A non-match:
match_with_regexp_pattern(
pattern
=>
"YouTube/video_id"
,
string
=>
"foo"
);
Result:
[
200,
"OK"
,
"String DOES NOT match regexp pattern YouTube::video_id"
,
{
"cmdline.exit_code"
=> 1 },
]
A match:
match_with_regexp_pattern(
pattern
=>
"YouTube/video_id"
,
string
=>
"Yb4EGj4_uS0"
);
Result:
[
200,
"OK"
,
"String matches regexp pattern YouTube::video_id"
,
{
"cmdline.exit_code"
=> 0 },
]
This function is not exported.
Arguments ('*' denotes required arguments):
anchor => bool
Generate an anchored version of the pattern.
captures => bool
Return array of captures instead of just a boolean status.
gen_args => hash
Supply generator arguments.
If pattern is a dynamic pattern (generated on-demand) and the generator requires some arguments, you can supply them here.
pattern* => regexppattern::name
Name of pattern, with module prefix but without the 'Regexp::Pattern'.
quiet => bool
string* => str
Returns an enveloped result (an array).
First element ($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)

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.
