powershell 脚本格式表输出中的颜色词 [英] Color words in powershell script format-table output

问题描述

是否可以使用格式表为 powershell 输出仅着色某些单词(而不是完整的行).例如，此脚本递归扫描文件夹中的字符串，然后使用 format-table 输出结果.

Is it possible to color only certain words (not complete lines) for a powershell output using format-table. For example, this script scans a folder recursively for a string and then output the result with format-table.

dir -r -i *.* | Select-String $args[0] |
format-table -Property @{label="Line #"; Expression={$_.LineNumber}; width=6},
Path, Line -wrap

如果能够使用特定颜色格式化我们正在搜索的单词，这样您就可以准确地看到它在行上的位置.

It would be nice to be able to format the word we are searching for with a specific color, so that you can see exactly where it was found on the line.

推荐答案

您可以将表通过管道传输到 Out-String，然后使用 Write-Host 将字符串分成几部分> 使用 -NoNewLine 开关.

You could pipe the table into Out-String, then write the string in parts using Write-Host with the -NoNewLine switch.

像这样:

filter ColorWord {
    param(
        [string] $word,
        [string] $color
    )
    $line = $_
    $index = $line.IndexOf($word, [System.StringComparison]::InvariantCultureIgnoreCase)
    while($index -ge 0){
        Write-Host $line.Substring(0,$index) -NoNewline
        Write-Host $line.Substring($index, $word.Length) -NoNewline -ForegroundColor $color
        $used = $word.Length + $index
        $remain = $line.Length - $used
        $line = $line.Substring($used, $remain)
        $index = $line.IndexOf($word, [System.StringComparison]::InvariantCultureIgnoreCase)
    }
    Write-Host $line
}

Get-Process| Format-Table| Out-String| ColorWord -word 1 -color magenta
