Question

When inside a Git repository, is it possible to add tab completion for branches to Powershell? For example:

PS> git checkout maTAB

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.
