Dist::Zilla Bash Completion

Basic tab completion for dzil, the Perl distribution power-tool for CPAN distribution.

Introduction

The completion implementation requires dzil to be installed (of course), it uses dzil built-in commands command to extract what is available and makes this accessible for tab completion.

In addition installed Dist::Zilla command plugins are automatically exposed by dzil meaning that tab completions are also automatically supported.

This is based on Dist::Zilla 6.009.

Usage

$ dzil <tab>
add    build    commands   help    listdeps   nop   run   smoke   authordeps   clean  install  new        release setup      test

If you have additional Dist::Zilla::App::Command plugins installed this will be discovered by Dist::Zilla and hence listed by this utility automatically.

Example: Dist::Zilla::App::Command::cover

$ dzil <tab>
add    build    commands   help    listdeps   nop   run   smoke   authordeps   clean  install  new        release setup      cover test

listdeps offer the additional completions:

$ dzil listdeps <tab>
--missing --develop --author --missing --requires --no-requires --recommends --no-recommends --suggests --no-suggests --versions --cpanm-versions --json --omit-cores

authordeps offer the additional completions:

$ dzil authordeps <tab>
--root --missing --versions

Download

$ curl https://raw.githubusercontent.com/jonasbn/bash_completion_dzil/master/dzil > dzil

Installation

When downloaded you have to install the completion implementation. 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 directory for your completions:

mkdir ~/.bash_completion.d

Copy your completions into the newly created directory:

cp dzil ~/.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 dzil /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 dzil /usr/local/etc/bash_completion.d/

And to activate right away:

source  /usr/local/etc/bash_completion.d/dzil

bash 4

Formula: bash-completions2.

cp dzil /usr/local/share/bash-completion/completions/

And to activate right away:

source /usr/local/share/bash-completion/completions/dzil

Motivation

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

History

• 1.0.0
  • Initial version working with bash version 4.

See Also

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 (see version 1.0.0).

Versions after version 1.0.0 have been tested with bash version 4.

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.
