在一个命令中使用 PowerShell 中的多种前景色 [英] Multiple foreground colors in PowerShell in one command

问题描述

我想用一个语句输出许多不同的前景色.

PS C:>写入主机红色"-ForegroundColor 红色红色的

这个输出是红色的.

PS C:>写入主机蓝色"-ForegroundColor 蓝色蓝色

这个输出是蓝色的.

PS C:>Write-Host "Red", "Blue" -ForegroundColor Red, Blue红蓝

此输出是洋红色，但我希望通过 one 命令将单词 red 的颜色设为红色，将单词 blue 设为蓝色.我该怎么做?

解决方案

编辑(2018 年 5 月 7 日):我已将 Write-Color 更新为 0.5 并发布它作为模块.代码现已发布在 github 上.

0.5 中的变化:

• 添加背景色
• 为较短的代码添加了别名 T/B/C
• 为函数添加别名(可与WC"一起使用)
• 修复了模块发布

0.4 的变化

• 修复了一些小问题
• 作为模块发布

• 它实际上为 Josh 脚本带来了额外的检查和功能.

  I want to output many different foreground colors with one statement.

  PS C:> Write-Host "Red" -ForegroundColor Red
  Red
  

  This output is red.

  PS C:> Write-Host "Blue" -ForegroundColor Blue
  Blue
  

  This output is blue.

  PS C:> Write-Host "Red", "Blue" -ForegroundColor Red, Blue
  Red Blue
  

  This output is magenta, but I want the color to be red for the word red, and blue for the word blue via the one command. How can I do that?

  解决方案

  Edit (7th May 2018): I've updated Write-Color to 0.5 and published it as module. Also code is now published on github.

  Changes in 0.5:

  • added backgroundcolor
  • added aliases T/B/C to shorter code
  • added alias to function (can be used with "WC")
  • fixes to module publishing

  Changes in 0.4

  • fixed small issues
  • published as module

  Links to resources:

  • GitHub Repository
  • GitHub Reporting Issues
  • PowerShellGallery Module
  • Module description and a starting point.

  Thanks to published module you can easily use the code as below:

  Install-Module PSWriteColor
  Write-Color -Text "Some","Text" -Color Yellow,Red
  

  There is no more need to copy/paste code. Enjoy.

  Old code is below. It's highly advised to use links above for newest code:

  Edit (9th April 2018): I've updated Write-Color to v0.3. Feel free to get it at my site where I'm maintaining Write-Color. There are few small changes. Inluded -NoNewLine and -ShowTime option.

  Edit (Jun 2017): updated with new version, added logging to file for logging purposes

  Josh method was so great that I actually went and expanded it a bit for my needs. I've written blog post How to format PowerShell with Multiple Colors about it (with screenshots and all - for the whole story and usage).

      function Write-Color([String[]]$Text, [ConsoleColor[]]$Color = "White", [int]$StartTab = 0, [int] $LinesBefore = 0,[int] $LinesAfter = 0, [string] $LogFile = "", $TimeFormat = "yyyy-MM-dd HH:mm:ss") {
      # version 0.2
      # - added logging to file
      # version 0.1
      # - first draft
      # 
      # Notes:
      # - TimeFormat https://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx
  
      $DefaultColor = $Color[0]
      if ($LinesBefore -ne 0) {  for ($i = 0; $i -lt $LinesBefore; $i++) { Write-Host "`n" -NoNewline } } # Add empty line before
      if ($StartTab -ne 0) {  for ($i = 0; $i -lt $StartTab; $i++) { Write-Host "`t" -NoNewLine } }  # Add TABS before text
      if ($Color.Count -ge $Text.Count) {
          for ($i = 0; $i -lt $Text.Length; $i++) { Write-Host $Text[$i] -ForegroundColor $Color[$i] -NoNewLine } 
      } else {
          for ($i = 0; $i -lt $Color.Length ; $i++) { Write-Host $Text[$i] -ForegroundColor $Color[$i] -NoNewLine }
          for ($i = $Color.Length; $i -lt $Text.Length; $i++) { Write-Host $Text[$i] -ForegroundColor $DefaultColor -NoNewLine }
      }
      Write-Host
      if ($LinesAfter -ne 0) {  for ($i = 0; $i -lt $LinesAfter; $i++) { Write-Host "`n" } }  # Add empty line after
      if ($LogFile -ne "") {
          $TextToFile = ""
          for ($i = 0; $i -lt $Text.Length; $i++) {
              $TextToFile += $Text[$i]
          }
          Write-Output "[$([datetime]::Now.ToString($TimeFormat))]$TextToFile" | Out-File $LogFile -Encoding unicode -Append
      }
  }
  
  
  Write-Color -Text "Red ", "Green ", "Yellow " -Color Red,Green,Yellow
  
  Write-Color -Text "This is text in Green ",
                     "followed by red ",
                     "and then we have Magenta... ",
                     "isn't it fun? ",
                     "Here goes DarkCyan" -Color Green,Red,Magenta,White,DarkCyan
  
  Write-Color -Text "This is text in Green ",
                     "followed by red ",
                     "and then we have Magenta... ",
                     "isn't it fun? ",
                     "Here goes DarkCyan" -Color Green,Red,Magenta,White,DarkCyan -StartTab 3 -LinesBefore 1 -LinesAfter 1
  
  Write-Color "1. ", "Option 1" -Color Yellow, Green
  Write-Color "2. ", "Option 2" -Color Yellow, Green
  Write-Color "3. ", "Option 3" -Color Yellow, Green
  Write-Color "4. ", "Option 4" -Color Yellow, Green
  Write-Color "9. ", "Press 9 to exit" -Color Yellow, Gray -LinesBefore 1
  
  
  
  Write-Color -LinesBefore 2 -Text "This little ","message is ", "written to log ", "file as well." -Color Yellow, White, Green, Red, Red -LogFile "C:	esting.txt" -TimeFormat "yyyy-MM-dd HH:mm:ss"
  Write-Color -Text "This can get ","handy if ", "want to display things, and log actions to file ", "at the same time." -Color Yellow, White, Green, Red, Red -LogFile "C:	esting.txt"
  

  It actually brings additional checks and features over Josh script.
