CPANMinus Bash Completion

Basic tab completion for cpanm.

Introduction

This is a basic completion implementation for cpanm (App::cpanminus) based on version 1.7043.

Usage

$ cpanm --<tab>

Download

$ curl https://raw.githubusercontent.com/jonasbn/bash_completion_cpanm/master/cpanm > cpanm

Installation

Where your completions are located might vary.

Personal

If you want to install them for your personal use, do the following.

Create the file: ~/.bash_completion, containing the code below:

for bcfile in ~/.bash_completion.d/* ; do
  . $bcfile
done

Ref: ServerFault.com: Standard place for user defined bash_completion.d scripts?

Create a directiory for your completions:

$ mkdir ~/.bash_completion.d

Copy your completions into the newly created directory:

$ cp cpanm ~/.bash_completion.d/

Start a new shell and you should be good to go.

System-wide example from Debian

Based on an introduction to bash completions on Debian.

$ sudo cp cpanm /etc/bash_completion.d/

System-wide example from OSX

This assumes you are using Homebrew

Do note that paths vary based on whether you are using bash 3 or 4

bash 3 (Formula: bash-completions):

$ cp cpanm /usr/local/etc/bash_completion.d/

And to activate right away:

$ source  /usr/local/etc/bash_completion.d/cpanm

bash 4 (Formula: bash-completions2)

$ cp cpanm /usr/local/share/bash-completion/completions/

And to activate right away:

$ source /usr/local/share/bash-completion/completions/cpanm

Motivation

cpanm is an important tool in my toolchain, so I wanted to have easy access to all the options available.

The programmatic capabilities of bash are truly powerful and useful and can be put to good use in use-cases like this.

A more elaborate piece of documentation on bash completions is available from The Linux Documentation Project in the Advanced Bash-Scripting Guide.

From the GNU Documentation.

Good two-part article, "An Introduction to Bash Completion": Part 1 and Part 2.

Please note that this experimental implementation has only been tested with bash version 3.

The most comprehensive collection of bash completions I have come across is the one from the Debian Linux distribution. It is also the one offered for OSX via Homebrew.
