自定义 PowerShell 提示[关闭]

我正在寻找自定义 Powershell 的不同示例prompt函数实现。如果您有自己的自定义实现，请发布脚本。现有资源的链接也很好。

发布提示实际外观的屏幕截图（预览）可以获得奖励积分。

这是 jaykul 提示的修改版本。这样做的好处是

-有一个当前历史记录ID，因此您可以非常轻松地调用历史记录中的先前项目（您知道该ID） - 这是一个小提醒 - 我将我的任务添加到提示中，这样我就不会忘记它们（请参阅截图）

function prompt {
  $err = !$?
  $origOfs = $ofs;
  $ofs = "|"
  $toPrompt = "$($global:__PromptVars)"
  $ofs = $origOfs;
  if ($toPrompt.Length -gt 0) { 
    Write-Host "$($toPrompt) >" -ForegroundColor Green -NoNewline }

  $host.UI.RawUI.WindowTitle = "PS1 > " + $(get-location)

  # store the current color, and change the color of the prompt text
  $script:fg = $Host.UI.RawUI.ForegroundColor
  # If there's an error, set the prompt foreground to "Red"
  if($err) { $Host.UI.RawUI.ForegroundColor = 'Red' }
  else { $Host.UI.RawUI.ForegroundColor = 'Yellow' }

  # Make sure that Windows and .Net know where we are at all times
  [Environment]::CurrentDirectory = (Get-Location -PSProvider FileSystem).ProviderPath

  # Determine what nesting level we are at (if any)
  $Nesting = "$([char]0xB7)" * $NestedPromptLevel

  # Generate PUSHD(push-location) Stack level string
  $Stack = "+" * (Get-Location -Stack).count

  # Put the ID of the command in, so we can get/invoke-history easier
  # eg: "r 4" will re-run the command that has [4]: in the prompt
  $nextCommandId = (Get-History -count 1).Id + 1
  # Output prompt string
  # Notice: no angle brackets, makes it easy to paste my buffer to the web
  Write-Host "[${Nesting}${nextCommandId}${Stack}]:" -NoNewLine

  # Set back the color
  $Host.UI.RawUI.ForegroundColor = $script:fg

  if ($toPrompt.Length -gt 0) { 
      $host.UI.RawUI.WindowTitle = "$($toPrompt) -- " + $host.UI.RawUI.WindowTitle
  }
  " "
}
function AddTo-Prompt($str) {
  if (!$global:__PromptVars) { $global:__PromptVars = @() }
  $global:__PromptVars += $str
}
function RemoveFrom-Prompt($str) {
  if ($global:__PromptVars) {
    $global:__PromptVars = @($global:__PromptVars | ? { $_ -notlike $str })
  }
}
