App::pmgrep - Print lines from installed Perl module sources matching a pattern


This document describes version 0.734 of App::pmgrep (from Perl distribution App-PMUtils), released on 2020-06-12.




 pmgrep(%args) -> [status, msg, payload, meta]

Print lines from installed Perl module sources matching a pattern.

This is a like the Unix command grep but instead of specifying filenames, you specify module names or prefixes. The utility will search module source files from Perl's @INC.


 # Find pre-increment in all Perl module files
 % pmgrep '\+\+\$'
 # Find some pattern in all Data::Sah::Coerce::* modules (note ** wildcard for recursing)
 % pmgrep 'return ' Data::Sah::Coerce::**

This function is not exported.

Arguments ('*' denotes required arguments):

  • all => true

    Require all patterns to match, instead of just one.

  • color => str

  • count => true

    Supress normal output, return a count of matching lines.

  • ignore_case => bool

  • invert_match => bool

    Invert the sense of matching.

  • line_number => true

  • modules => perl::modnames

    If not specified, all installed Perl modules will be searched.

  • pattern => re

  • pm => bool (default: 1)

    Whether to include .pm files.

  • pmc => bool

    Whether to include .pmc files.

  • pod => bool

    Whether to include .pod files.

  • quiet => true

  • recursive => true

  • regexps => array[re]

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)
