c# - 自定义 PowerShell 提示符 - 相当于 CMD 的 $M$P$_$+$G?

Question

我已经开始“玩弄”PowerShell 并试图让它“正常运行”。

我想做的一件事是将 PROMPT 自定义为“类似于”MS-Dos 上的“$M$P$_$+$G”:

这些功能的简要概述:

字符|说明
$m 与当前驱动器盘符关联的远程名称，如果当前驱动器不是网络驱动器，则为空字符串。
$p 当前驱动器和路径
$_ 输入换行
$+ 零个或多个加号 (+) 字符，具体取决于 pushd 目录堆栈的深度，每个插入的级别一个字符
$g >(大于号)

所以最终的输出是这样的:

    \\spma1fp1\JARAVJ$ H:\temp
    ++>

我已经能够将 $M 和 $_ 功能(以及一个漂亮的历史记录功能)添加到我的提示中，如下所示:

function prompt
{
   ## Get the history. Since the history may be either empty,
   ## a single item or an array, the @() syntax ensures
   ## that PowerShell treats it as an array
   $history = @(get-history)


   ## If there are any items in the history, find out the
   ## Id of the final one.
   ## PowerShell defaults the $lastId variable to '0' if this
   ## code doesn't execute.
   if($history.Count -gt 0)
   {
      $lastItem = $history[$history.Count - 1]
      $lastId = $lastItem.Id
   }

   ## The command that we're currently entering on the prompt
   ## will be next in the history. Because of that, we'll
   ## take the last history Id and add one to it.
   $nextCommand = $lastId + 1

   ## Get the current location
   $currentDirectory = get-location

   ## Set the Windows Title to  the current location
   $host.ui.RawUI.WindowTitle = "PS: " + $currentDirectory

   ## And create a prompt that shows the command number,
   ## and current location
   "PS:$nextCommand $currentDirectory
>"
}

但其余的还不是我设法复制的东西......

非常感谢您一定会提供的提示!

看看这是否符合您的要求:

function prompt
{
   ## Get the history. Since the history may be either empty,
   ## a single item or an array, the @() syntax ensures
   ## that PowerShell treats it as an array
   $history = @(get-history)


   ## If there are any items in the history, find out the
   ## Id of the final one.
   ## PowerShell defaults the $lastId variable to '0' if this
   ## code doesn't execute.
   if($history.Count -gt 0)
   {
      $lastItem = $history[$history.Count - 1]
      $lastId = $lastItem.Id
   }

   ## The command that we're currently entering on the prompt
   ## will be next in the history. Because of that, we'll
   ## take the last history Id and add one to it.
   $nextCommand = $lastId + 1

   ## Get the current location
   $currentDirectory = get-location

   ## Set the Windows Title to  the current location
   $host.ui.RawUI.WindowTitle = "PS: " + $currentDirectory

   ##pushd info
   $pushdCount = $(get-location -stack).count
   $pushPrompt = ""
   for ($i=0; $i -lt $pushdCount; $i++)
   {
       $pushPrompt += "+"
    }

   ## And create a prompt that shows the command number,
   ## and current location
   "PS:$nextCommand $currentDirectory `n$($pushPrompt)>"
}
