powershell - 将主机写入列(格式化输出)

Question

我正在尝试使用 Write-Host将数据输出到列中。我找到了一种方法来做到这一点，但它非常困惑:

首先，我使用以下函数设置控制台大小:

function fn_SetConsoleSize {
    param ([int]$height, [int]$width, [string]$title)

    $bheight = $height
    if ($height -le 50) { 
        $bHeight = 51
    }

    $bwidth = $width
    if ($width -le 150) { 
        $bwidth = 150
    }

    $pshost = Get-Host
    $pswindow = $pshost.ui.rawui
    $newsize = $pswindow.buffersize
    $newsize.height = $bHeight
    $newsize.width = $bwidth
    $pswindow.buffersize = $newsize

    <# Window Size #>
    $newsize = $pswindow.windowsize
    $newsize.height = $height
    $newsize.width = $width
    $pswindow.windowsize = $newsize

    <# Other Console Changes #>
    $pswindow.windowtitle = $title
    $pswindow.foregroundcolor = "Yellow"
    $pswindow.backgroundcolor = "Black"
}

然后我只使用空格设置列大小:

Write-Host ( " " * 20 ) "Candidates        = $($Counts[0])" -nonewline
Write-Host (" " * ( 32 - $($Counts[0]).tostring().length)) "Candidates        = $($Counts[0])"

Write-Host ( " " * 20 ) "Contacts          = $($Counts[1])" -nonewline
Write-Host (" " * ( 32 - $($Counts[1]).tostring().length))  "Contacts          = $($Counts[1])"

这确实按照我想要的方式输出，但是我的项目的这一部分会很长，所以如果可能的话我想大大简化它。

这是一个输出示例:

StephenP 为您指明了方向。

至于这个……

it does help but I wouldn't be able to keep the colours using here-strings, but that's not really an issue. Out of interest, why would you avoid using Write-Host?

长期以来，使用 Write-Host 一直是一个热门话题。甚至是 PowerShell 的发明者/作者。

Write-Host Considered Harmful - by PowerShell founder Jeffrey Snover

http://www.jsnover.com/blog/2013/12/07/write-host-considered-harmful

When you are writing or reviewing PowerShell scripts, I’d like you to remember the following rule of thumb:

◾Using Write-Host is almost always wrong.

Write-Host is almost always the wrong thing to do because it interferes with automation. There are typically two reasons why people use Write-Host:

关于该主题还有很多其他文章。在早期版本的 PoSH 中，Write-Host 不能在管道中使用，因为当你使用它时，数据就从缓冲区中消失了。

However, in PoSHv5 Jeffrey Snover now says...

With PowerShell v5 Write-Host no longer "kills puppies". data is captured into info stream https://learn.microsoft.com/en-us/powershell/module/Microsoft.PowerShell.Utility/Write-Information?view=powershell-5.1

Description

The Write-Information cmdlet specifies how Windows PowerShell handles information stream data for a command.

Windows PowerShell 5.0 introduces a new, structured information stream (number 6 in Windows PowerShell streams) that you can use to transmit structured data between a script and its callers (or hosting environment). Write-Information lets you add an informational message to the stream, and specify how Windows PowerShell handles information stream data for a command.

通过执行此操作，您仍然可以在不使用 Write 主机的情况下使用颜色......

PowerTip:在不使用 Write-Host 的情况下以彩色写入 PowerShell 输出

总结:在不使用 Write-Host cmdlet 的情况下将彩色输出写入 Windows PowerShell 控制台。

您好，脚本专家!问题 如何在不使用 Write-Host cmdlet 的情况下将输出写入 Windows PowerShell 控制台？

您好，脚本专家!回答 使用 $host.Ui.RawUi 将 ForegroundColor 设置为不同的颜色，然后使用 Write-Output cmdlet 写入输出。完成后，将 ForegroundColor 设置回其原始颜色。

$t = $host.ui.RawUI.ForegroundColor

$host.ui.RawUI.ForegroundColor = "DarkGreen"

Write-Output "this is green output"

this is green output

$host.ui.RawUI.ForegroundColor = $t

...但恕我直言，这有点麻烦。

我编写了一个名为 Set-TextColor 的函数，并将其保存在我的个人资料中以便于访问和使用。
