我可以在 Powershell 中转义颜色代码,以便不需要使用 -ForeGroundColor 吗? [英] Can I escape a color code in Powershell so I do not need to use -ForeGroundColor?
问题描述
是否可以使用一些颜色代码转义字符,这样我就不需要提及 -ForeGroundColor 参数?
Is it possible to use some color-code escape character so that I do not need to mention -ForeGroundColor parameter?
所以而不是:
write-Host "Hello World!" -ForegroundColor:Blue
我可以这样做吗:
write-Host "Hello \{somethinghere to denote from this point it will be in BLUE color} World!"
推荐答案
这是一个解决不支持 ANSI 转义码的 powershell 的解决方案.
Here's a solution that gets around powershell not supporting ANSI escape codes.
这应该允许您指定用作分隔符的字符
This should allow you to specify what character you use as a delimiter
function Write-Colored {
param(
[Parameter(Mandatory=$True, Position=1)]
[string]$text,
[Parameter(Mandatory=$True, Position=2)]
[string]$delimiter
)
$i = $text.Split($delimiter)
function pr ([string]$item, [System.ConsoleColor]$color){
Write-Host $item.Substring(1) -fore $color -NoNewline
}
foreach ($item in $i){
$colorcode = $item.ToCharArray()[0]
switch($colorcode){
"b" { pr $item Blue }
"r" { pr $item Red }
"g" { pr $item Green }
"y" { pr $item Yellow }
default { Write-Host $item -NoNewline }
}
}
}
在开关块中,添加任何您想要对应于某种颜色的速记代码.我选择了单个字符,因为它更容易验证,结果如下:
in the switch block, add whatever shorthand codes you want to correspond to a certain color. I picked single characters since its easier to validate against, and the results are as follows:
$text = "#rmy #gname #yis #bchris"
输出类似
请记住,在使用此辅助函数时,您需要使用
just keep in mind, while using this helper function, you will need to use
`n
用于在文本中添加换行符,或者根据需要在函数底部添加 write-host ""
.
for adding newlines to your text, or add a write-host ""
to the bottom of your function if desired.
修改后的代码更可靠
