This document describes version 0.53 of pmlines (from Perl distribution App-PMUtils), released on 2015-12-07.


 % pmlines HTTP::Tiny LWP::UserAgent
 | blank | code | comment | module         | pod | total |
 | 482   | 988  | 276     | HTTP::Tiny     | 686 | 2136  |

* marks required options.

Configuration options


Set path to configuration file.

Can be specified multiple times.


Set configuration profile to use.


Do not use any configuration file.

Environment options


Do not read environment for default options.

Output options


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

Default value:


Set output format to json.


When outputing as JSON, strip result envelope.

Default value:


By default, when outputing as JSON, the full enveloped result is returned, e.g.:


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:


Other options

--help, -h, -?

Display help message and exit.


See --module.


Can be specified multiple times.

--version, -v

Display program's version and exit.


App::cloc which uses the cloc program and can output number of {code,blank,comment} lines in a Perl source code (as well as other languages). Results might differ slightly with result from this utility.

pllines (from App::PlUtils distribution)


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


To activate bash completion for this script, put:

 complete -C pmlines pmlines

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 shcompgen which allows you to activate completion scripts for several kinds of scripts on multiple shells. Some CPAN distributions (those that are built with Dist::Zilla::Plugin::GenShellCompletion) will even automatically enable shell completion for their included scripts (using shcompgen) at installation time, so you can immadiately have tab completion.


To activate tcsh completion for this script, put:

 complete pmlines 'p/*/`pmlines`/'

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.



Specify additional command-line options


This script can read configuration file, which by default is searched at ~/.config/pmlines.conf, ~/pmlines.conf or /etc/pmlines.conf (can be changed by specifying --config-path). All found files will be read and merged.

To disable searching for configuration files, pass --no-config.

Configuration file is in the format of IOD, which is basically INI with some extra features.

You can put multiple profiles in a single file by using section names like [profile=SOMENAME]. Those sections will only be read if you specify the matching --config-profile SOMENAME.

List of available configuration parameters:

 format (see --format)
 module (see --module)
 naked_res (see --naked-res)
