How do I add autocomplete to git aliases?

Question

I have setup git autocomplete using the git-autocomplete.bash file which works for standard commands and simple aliases ( co = checkout ), but I have a longer alias defined in my .git-config file that I would like to autocomplete branch names on and I cannot find how to do this.

I am on Windows Server 2012 R2 running git 2.10.2.windows.1

My alias looks like this:

mstage = "!git checkout stage && git pull && git reset --hard && git merge $1 --no-commit"

where $1 is a branch name - I'd love this to autocomplete

Answer 1

here we have two options for windows operating system:

msysgit

1. Download and place git-flow-completion.bash in home directory ( ~/ in msysgit shell)

2. Add a .bashrc file to your home directory with the following line (or add this line to existing .bashrc file):

   source ~/git-flow-completion.bash

Cygwin

1. Download and place git-flow-completion.bash in

   %CYGWIN_INSTALLATION_DIR%\\etc\\bash_completion.d

2. Rename it to git-flow

   you can autocomplete as following: git flow init etc.

Answer 2

@Rohit Poudels answer works if you are using bash on Windows. If you are using PowerShell, currently the only way to enable this autocomplete is to change posh-git manually after installing.

I changed the GitTabExpansion.ps1 file in posh-git, similarly to what is outlined on the repo .

More specifically, I added $line = $line -replace '^git mstage ', 'git checkout ' as the first line in the function TabExpansion which will in effect will treat my alias as equivalent to git checkout and tab expansion will then behave as expected
