#bash completion

Ran into another little snag in Kali Linux on WSL. It seems that I has to manually Enable Bash Autocomplete in Kali Linux for WSL or as the old Linux ways goes, install bash-autocompletion. Bash autocomplete is a handy feature that saves you time and keystrokes whilst working with the command line in Kali Linux. This powerful functionality allows you to press the Tab key to automatically complete…

If you use command completion for bash, you should be aware that your git distribution includes a couple of interesting add-ons:

your_git_installation/etc/bash_completion.d/git-completion.bash your_git_installation/etc/bash_completion.d/git-prompt.sh

The first file adds git to the bash completion module; all you have to do is source the git completion file in your .bash_rc file, and then bash will understand how to complete git commands.

git-prompt.sh lets you customize your bash prompt to include information from git whenever the working directory is part of a git repo. For example, my prompt looks like this:

(567)niflheim:~/path/to/repo[master *%]$

That last bit in the square brackets is the name of the current branch, followed by symbols to show that I have untracked files, and that some tracked files have been modified since the last commit.

tl;dr: Here's a bash script and an accompanying bash completion script that opens Sublime Text 2 projects.

I love Sublime Text 2. Its fast, lightweight, powerful and it doesn't get in your way. I also context switch between projects a lot. Sometimes I'll work on 5 different projects in one day at work. In order to keep my head straight, I use sublime text's notion of a project. A project is, at its core, just a list of folders to keep open in the sidebar. To create a project, just add a folder to your sidebar, and then save the project.

Once you have a few projects, you'll inevitably want to open them from the command line, and doing so can be cumbersome. (Sorry about the encoded ampersands, I'm working on fixing it.)

sublime_text --project /path/to/projects/myproject.sublime-project &

So I decided to create a little bash script to open up all the projects I want.

#!/usr/bin/env bash for proj in $@; do sublime_text --project /path/to/projects/${proj}.sublime-project & done

Suppose I put this in a file called subl on my $PATH. Then I can type subl myproject to open any project. Now, since I have ~20 projects, its hard to remember all the names, so I created a bash completion script.

_subl() { local cur=${COMP_WORDS[COMP_CWORD]} local list=`ls -1 /path/to/projects/*project | cut -d/ -f5 | cut -d. -f1` COMPREPLY=( $(compgen -W "${list}" -- ${cur}) ) } complete -F _subl subl

Now I can type subl myp[tab] and it will autocomplete for me!

Bir önceki yazımda unutmuşum, yeni farkettim. pip'i terminalde kullanırken bash-completion özelliğinden de faydalanabiliriz. Bunun için, pip'le gelen bash-completion'ı sisteme eklemek gerekiyor. Tabi, sizde zaten bash-completion kurulu diye var sayıyorum.

Eğer yoksa port'dan kurabilirsiniz: sudo port install bash-completion

pip'i kurduktan sonra terminalde şunu yazın;

$ pip completion --bash

Bu işlem aşağıdaki bash kodu oluşutuyor.

# pip bash completion start _pip_completion() { COMPREPLY=( $( COMP_WORDS="${COMP_WORDS[*]}" \ COMP_CWORD=$COMP_CWORD \ PIP_AUTO_COMPLETE=1 $1 ) ) } complete -o default -F _pip_completion pip # pip bash completion end

Bu kodu, /opt/local/etc/bash_completion.d/ altına "pip_completion" ismiyle kaydetmeniz lazım. Kolay yolu şu:

$ pip completion --bash > pip_completion | sudo mv pip_completion /opt/local/etc/bash_completion.d/
