如何在控制台中关闭语法高亮？

Question

我只想让PowerShell成为白色背景上的黑色文字.但是,PowerShell v5突出显示了我的命令,并使它们变黄,这是不可能看到的.有没有办法在PowerShell中关闭所有语法高亮？

Answer 1

PowerShell v5中的语法着色可以通过修改Set-PSReadlineOption.以下命令将注释的foregound和背景颜色设置为shell前景色和背景色:

Set-PSReadlineOption -TokenKind Comment -ForegroundColor $Host.UI.RawUI.ForegroundColor -BackgroundColor $Host.UI.RawUI.BackgroundColor

或者只是黑白:

Set-PSReadlineOption -TokenKind Comment -ForegroundColor Black -BackgroundColor White

您需要对所有TokenKind值执行此操作以完全删除语法着色.

如果您还想更改输出流颜色,可以通过主机PrivateData对象的属性执行此操作:

$Host.PrivateData.WarningForegroundColor = $Host.UI.RawUI.ForegroundColor
$Host.PrivateData.WarningBackgroundColor = $Host.UI.RawUI.BackgroundColor
...

将所有这些语句放入您的配置文件中,以便在每次启动PowerShell时应用它们,例如:

$HOME\Documents\WindowsPowerShell\profile.ps1

语法在最近的更新中发生了变化。旧语法现在会给你一个讨厌的错误消息：

Set-PSReadLineOption : A positional parameter cannot be found that accepts argument 'Command'.                                                             
At line:1 char:1                                                                
+ Set-PSReadLineOption 'Command' white black                                    
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~                                    
    + CategoryInfo          : InvalidArgument: (:) [Set-PSReadLineOption], ParameterBindingException
    + FullyQualifiedErrorId : PositionalParameterNotFound,Microsoft.PowerShell.SetPSReadLineOption                      

或者

Set-PSReadLineOption : A parameter cannot be found that matches parameter name  'TokenKind'.
At line:1 char:22
+ Set-PSReadlineOption -TokenKind Comment -ForegroundColor 'black' -Bac ...
+                      ~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Set-PSReadLineOption], Par ameterBindingException
    + FullyQualifiedErrorId : NamedParameterNotFound,Microsoft.PowerShell.SetP SReadLineOption
                                 

更新的语法似乎要求您传入新设置的字典。

Set-PSReadLineOption -Colors @{None='black';Comment='black';Keyword='black';String='black';Operator='black';Variable='black';Command='black';Parameter='black';Type='black';Number='black';Member='black'}

如果你得到

Set-PSReadLineOption: 'None' is not a valid color property

（这显然意味着你在 Linux 上），取出None='black';，像这样：

Set-PSReadLineOption -Colors @{Comment='black';Keyword='black';String='black';Operator='black';Variable='black';Command='black';Parameter='black';Type='black';Number='black';Member='black'}
