NAME

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

VERSION

This document describes version 0.721 of pmgrep (from Perl distribution App-PMUtils), released on 2019-02-24.

SYNOPSIS

Usage:

 % pmgrep [options] [pattern] [module] ...

DESCRIPTION

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.

OPTIONS

* marks required options.

Main options

--module=s@

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

Can be specified multiple times.

--modules-json=s

See --module.

--no-pm
--pattern=s
--pmc

Whether to include .pmc files.

--pod

Whether to include .pod files.

--recursive, -r
--regexp=s@

Can be specified multiple times.

--regexps-json=s

See --regexp.

-e=s@

Alias for -e.

See --regexp.

Can be specified multiple times.

General output control options

--color=s

Valid values:

 ["never","always","auto"]
--count, -c

Supress normal output, return a count of matching lines.

--quiet-arg, --silent, -q

Logging options

--debug

Shortcut for --log-level=debug.

--log-level=s

Set log level.

--quiet

Shortcut for --log-level=error.

--trace

Shortcut for --log-level=trace.

--verbose

Shortcut for --log-level=info.

Matching control options

--all

Require all patterns to match, instead of just one.

--ignore-case, -i
--invert-match, -v

Invert the sense of matching.

Output line prefix control options

--line-number, -n

Output options

--format=s

Choose output format, e.g. json, text.

Default value:

 undef
--json

Set output format to json.

--naked-res

When outputing as JSON, strip result envelope.

Default value:

 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]

Other options

--help, -h, -?

Display help message and exit.

--version, -V

Display program's version and exit.

COMPLETION

This script has shell tab completion capability with support for several shells.

bash

To activate bash completion for this script, put:

 complete -C pmgrep pmgrep

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.

tcsh

To activate tcsh completion for this script, put:

 complete pmgrep 'p/*/`pmgrep`/'

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).

other shells

For fish and zsh, install shcompgen as described above.
