Write-Verbose output that doesn't wrap to command width in Powershell

Question

I'd like to Write-Verbose a lot of data to an out file. Here's how I'm doing it.

Start-Transcript -Path $TargetDir\RunUnitTests.log -Width 1000000
Write-Verbose "five million character lines and stuff"

This works great, except that the output is auto wrapped to the standard width of a console, this makes the log look absolutely terrible.

I found a solution here^{dead link removed} , but it's so involved and complicated that I don't want to just throw this in my script below a comment #Thar be dragons.

Is there a better way to do this?

Answer 1

Here is a very simple workaround based on Write-Host which does not have such a problem. In the beginning of the session install/dot-source the replacement of the default Write-Verbose:

function global:Write-Verbose
(
    [string]
    $Message
)
{
    # check $VerbosePreference variable
    if ($VerbosePreference -ne 'SilentlyContinue') {
        # do this via Write-Host
        Write-Host "VERBOSE: $Message" -ForegroundColor 'Yellow'
    }
}

Then this works as needed:

$VerbosePreference = 'Continue'
Start-Transcript -Path .\RunUnitTests.log
Write-Verbose ("verbose writes five million character lines and stuff. " * 20)

That is: it takes into account $VerbosePreference, it writes to host in yellow, transcript output is not wrapped and it is still marked VERBOSE.
