Can I show the current revision/version of the branch in the prompt?

Posh shows the current branch in the commandprompt but it would be nice if it could also show the current branch revision/version/shorthash.

Maybe this is already possible but I'm not a powershell wizard yet.

This is not currently supported. What do you have in mind?

An easy way to retrieve the hash to be shown on the prompt. I created a function:

function Get-GitRevision()
{
    return git rev-parse HEAD | cut -c0-10>$null
}

This is slow and not really usable for the prompt but it is useful when you want to create a version number in which you want to include the hash.

You can do this without relying on cut.exe:

(git rev-parse HEAD).Substring(0,10)

[dahlbyk]

Or let git truncate for you: git rev-parse --short HEAD. :)

I'm not comfortable adding the revision to $GitStatus if it requires an extra function call...status makes the prompt slow enough as is. However, my gh69 branch lets you do the following:

$GitPromptSettings.AfterBranchScript = {
    param($status, $backgroundColor, $foregroundColor)
    Write-Prompt " ($(?? (Get-GitRevision -Short) 'new'))" `
        -BackgroundColor $backgroundColor -ForegroundColor $foregroundColor
}

On my machine, that displays the short revision after the branch, in the same color as the branch:

C:\Dev\GitHub\posh-git [gh69 (53ece22)]>

What do you think?

See issue #345. I think a better approach to such niche customization is to make it easier for folks to customize the content of the Git status summary text rather than adding more & more options to posh-git.
