In Powershell, add tab completion for git branches

Question

when inside a git repository, is it possible to add tab completion for git branches to Powershell? ie:

PS> git checkout ma<tab>

would result in

PS> git checkout master

Answer 1

For that to be possible, a git provider for PowerShell would need to exist.

After a quick search, something similar apparently exists, the bizarre but aptly named posh-git:

A set of PowerShell scripts which provide Git/PowerShell integration

• Prompt for Git repositories: The prompt within Git repositories can show the current branch and the state of files (additions, modifications,
  deletions) within.
• Tab completion: Provides tab completion for common commands when using git. E.g. git ch<tab> --> git checkout

Usage

See profile.example.ps1 as to how you can integrate the tab completion and/or git prompt into your own profile. You can also choose whether advanced git commands are shown in the tab expansion or only simple/common commands. Default is simple.

Here are some blog posts that explain how to do something like this:

Answer 3

I wrote a generic provider for PowerShell whose behaviour can be implemented entirely in powershell script. This would be an ideal starting spot to prototype a GIT provider if one does not exist (or is dead, or insufficent.)
