使用posh-git将远程名称添加到PowerShell提示符

Question

I'm using posh-git to add git information to my PowerShell prompt. I want to have my prompt include the remote repository name like the examples but can't find a way to do so.

Below is my profile with my custom prompt:

function prompt {
    $origLastExitCode = $LASTEXITCODE

    $curPath = $ExecutionContext.SessionState.Path.CurrentLocation.Path
    if ($curPath.ToLower().StartsWith($Home.ToLower())) {
        $curPath = "~" + $curPath.SubString($Home.Length)
    }

    Write-Host "$env:UserName" -NoNewline -ForegroundColor Cyan
    Write-Host "@" -NoNewline -ForegroundColor Yellow
    Write-Host "$(hostname)" -NoNewline
    Write-VcsStatus
    Write-Host "`n$curPath" -NoNewline

    $LASTEXITCODE = $origLastExitCode

    " $('>' * ($nestedPromptLevel + 1)) "
}

Import-Module posh-git

$global:GitPromptSettings.BeforeText = " ("
$global:GitPromptSettings.AfterText = ")"
$global:GitPromptSettings.EnableWindowTitle = "posh-git ~"
$global:GitPromptSettings.EnableStashStatus = $true
$global:GitPromptSettings.BeforeStashText = " {"
$global:GitPromptSettings.AfterStashText = "}"
$global:GitPromptSettings.BeforeStashForegroundColor = "Yellow"
$global:GitPromptSettings.AfterStashForegroundColor = "Yellow"
$global:GitPromptSettings.BranchUntrackedSymbol = "::"
$global:GitPromptSettings.BranchGoneStatusSymbol = "~~"
$global:GitPromptSettings.BranchIdenticalStatusToSymbol = "=="
$global:GitPromptSettings.BranchAheadStatusSymbol = "<<"
$global:GitPromptSettings.BranchBehindStatusSymbol = ">>"
$global:GitPromptSettings.BranchBehindAndAheadStatusSymbol = "><"

This is the result:

spike@Jacob-Laptop (master == +0 ~1 -0 !)
~\Documents\Projects\GUI Utilities\batch-media-file-converter >

This is what I want:

spike@Jacob-Laptop [spikespaz/batch-media-file-converter] (master == +0 ~1 -0 !)
~\Documents\Projects\GUI Utilities\batch-media-file-converter >

Answer 1

I got it working with the following code:

$remoteName = (git remote get-url origin).Split("/")

Write-Host $remoteName[-2] -NoNewline -ForegroundColor Cyan
Write-Host "/" -NoNewline -ForegroundColor Yellow
Write-Host $remoteName[-1] -NoNewline
Write-Host "]" -NoNewline -ForegroundColor Yellow

It has to only be executed if the current directory is a git directory. Check that with Test-Path ".git" .

The command git remote get-url origin returns the remote URL such as https://github.com/spikespaz/batch-media-file-converter . This can be split at / characters, where the last two indices are (user, repo) .

I also got it working by extracting the user and repository name with regex ( ([^\\/]*)\\/([^\\/]*)$ ), but I presume splitting is faster.

The only problem I see with this is that the URL returned from the command may have .git or something at the end. It could also be an SSH address. I don't use either of those types of git addresses, so if anyone finds that this breaks let me know.

$remoteName = [regex]::match((git remote get-url origin), "([^\/]*)\/([^\/]*)$").Groups

Write-Host $remoteName[1] -NoNewline -ForegroundColor Cyan
Write-Host "/" -NoNewline -ForegroundColor Yellow
Write-Host $remoteName[2] -NoNewline
Write-Host "]" -NoNewline -ForegroundColor Yellow

This is the full code: See edit.

 function Prompt() { <...> } Import-Module posh-git 

I would still like to know how it was done in the example, and I'm sure it would be cleaner however that was done, so I won't accept this as an answer but rather leave it here as a workaround. Edit 2: I am accepting this as an answer for now because I had expected someone else to respond, but nobody did. It is the only solution I've found this-far.

Edit: If you like this profile configuration, I've made a gist that I will update whenever I change it. https://git.io/vAqYP
