Mercurial integration for PowerShell
Latest commit e273b0d Apr 10, 2015 @JeremySkinner Merge pull request #35 from woodyza/master
Make tab expansion case-insensitive for branches, tags and bookmarks


Inspired by the Posh-Git project (, Posh-Hg provides a set of PowerShell scripts which provide Mercurial/PowerShell integration

Prompt for Hg repositories

The prompt within Hg 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 hg.
E.g. hg up<tab> --> hg update


See profile.example.ps1 as to how you can integrate the tab completion and/or hg prompt into your own profile. Prompt formatting, among other things, can be customized using the $PoshHgSettings variable.


  1. Verify you have PowerShell 2.0 or better with $PSVersionTable.PSVersion

  2. Verify execution of scripts is allowed with Get-ExecutionPolicy (should be RemoteSigned or Unrestricted). If scripts are not enabled, run PowerShell as Administrator and call Set-ExecutionPolicy RemoteSigned -Confirm.

  3. Verify that hg can be run from PowerShell. If the command is not found, you will need to add a hg alias or add %ProgramFiles%\TortoiseHg to your PATH environment variable.

  4. Clone the posh-hg repository to your local machine.

  5. From the posh-hg repository directory, run .\install.ps1.

  6. Enjoy!

The Prompt

PowerShell generates its prompt by executing a prompt function, if one exists. posh-hg defines such a function in profile.example.ps1 that outputs the current working directory followed by an abbreviated hg status:

C:\Users\JSkinner [default]>

By default, the status summary has the following format:

[{HEAD-name} +A ~B -C ?D !E ^F <G:H>]
  • {HEAD-name} is the current branch, or the SHA of a detached HEAD
    • Cyan means the branch matches its remote
    • Red means the branch is behind its remote
  • ABCDEFGH represent the working directory
    • + = Added files
    • ~ = Modified files
    • - = Removed files
    • ? = Untracked files
    • ! = Missing files
    • ^ = Renamed files
    • <G:H> = Current revision information matching the output of hg log -r . --template '{rev}:{node|short}'

Additionally, Posh-Hg can show any tags and bookmarks in the prompt as well as MQ patches if the MQ extension is enabled (disabled by default)
