# Perlbrew Bash Completion
Basic tab completion for [perlbrew](https://perlbrew.pl/).
[](https://opensource.org/licenses/MIT)
## Usage
This completion script, executes `perlbrew list` and offers completions for all the `perlbrew` perls and libraries installations you have available.
```bash
$ perlbrew use
perl-5.10.1
perl-5.20.2
perl-5.20.2@workflow
...
```
And the `bash` completion functionality even assists, when you specify more of your targets
```bash
$ perlbrew use perl-5.20
perl-5.20.2
perl-5.20.2@workflow
...
```
## Download
```bash
$ curl https://raw.githubusercontent.com/jonasbn/bash_completion_perlbrew/master/perlbrew > perlbrew
```
## 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:
```bash
for bcfile in ~/.bash_completion.d/* ; do
. $bcfile
done
```
Ref: [ServerFault.com: _Standard place for user defined bash_completion.d scripts?_](https://serverfault.com/questions/506612/standard-place-for-user-defined-bash-completion-d-scripts)
Create a directory for your completions:
```bash
$ mkdir ~/.bash_completion.d
```
Copy your completions into the newly created directory:
```bash
$ cp perlbrew ~/.bash_completion.d/
```
Start a new shell and you should be good to go.
### System-wide example from Debian
Based on [an introduction](https://debian-administration.org/article/316/An_introduction_to_bash_completion_part_1) to `bash` completions on Debian.
```bash
$ sudo cp perlbrew /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`)
```bash
$ cp perlbrew /usr/local/etc/bash_completion.d/
```
And to activate right away:
```bash
$ source /usr/local/etc/bash_completion.d/perlbrew
```
#### `bash` 4 (Formula: `bash-completions2`)
```bash
$ cp perlbrew /usr/local/share/bash-completion/completions/
```
And to activate right away:
```bash
$ source /usr/local/share/bash-completion/completions/perlbrew
```
## Motivation
I have a huge list of `perlbrew` library installations and I tend to keep the names long and descriptive, so it seemed like tab completion was an interesting alternative to the _flow breaking copy-pasting_ and error prone typing away.
The programmatic capabilities of `bash` are truly powerful and useful and can be put to good use in use-cases like this.
## See Also
A more elaborate piece of documentation on `bash` completions is available from **The Linux Documentation Project** in the [Advanced Bash-Scripting Guide](http://tldp.org/LDP/abs/html/tabexpansion.html).
From the [GNU Documentation](https://www.gnu.org/software/bash/manual/html_node/Programmable-Completion.html).
Good two-part article, "An Introduction to Bash Completion": [Part 1](https://debian-administration.org/article/316/An_introduction_to_bash_completion_part_1) and [Part 2](https://debian-administration.org/article/317/An_introduction_to_bash_completion_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](https://github.com/scop/bash-completion) from the **Debian Linux distribution**. It is also the one offered for OSX via **Homebrew**.
