Question:
I got this colored dir script from http://tasteofpowershell.blogspot.com/2009/02/get-childitem-dir-results-color-coded.html:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
function ls { $regex_opts = ([System.Text.RegularExpressions.RegexOptions]::IgnoreCase -bor [System.Text.RegularExpressions.RegexOptions]::Compiled) $fore = $Host.UI.RawUI.ForegroundColor $compressed = New-Object System.Text.RegularExpressions.Regex('\.(zip|tar|gz|rar) It works great, but I most of the time I want only the file names, in wide format. So after the invoke-expression call, I added %{ if ($_.GetType().Name -eq 'DirectoryInfo') { : : : $_ } } | format-wide -property Name } |
Now I have a bug. Only the colour of the second column is correct; the first item in each column takes the colour of the item in the second column. For example, if I have
|
1 2 3 4 |
> ls Directory Program.exe |
Then both Directory and Program.exe will be red, even though Directory is supposed to be DarkCyan. How can I correct this?
Answer:
Rather than twiddling the foreground/background colors of the host in between displaying text to the screen, why don't you use Write-Host which gives you a bit more control over the displayed text (you can control when newlines are output) e.g.:
|
1 2 |
$_ | Out-String -stream | Write-Host -Fore Red |
And for the wide listing use, you will need to handle the column formatting yourself unless you want to update the format data XML for the DirectoryInfo/FileInfo types. If you don't want to do that, then you can write out each name - padded out appropriately - with the desired color. On the last column, set the -NoNewLine param to $false:
|
1 2 3 4 5 6 |
$width = $host.UI.RawUI.WindowSize.Width $cols = 3 ls | % {$i=0; $pad = [int]($width/$cols) - 1} ` {$nnl = ++$i % $cols -ne 0; ` Write-Host ("{0,-$pad}" -f $_) -Fore Green -NoNewLine:$nnl} |
