Vista - Dir with Color

Hello!

I try to create a function like the Linux ls. To do a ls, I use
Get-ChildItem | Format-Wide -Autosize.
The only distinction is that Directory is in "[ ]". But I like to change
color (Red for exe, Blue for Directory, etc.)

Any idea? I've found a function sample using $Host.ui.rawui.foregroundcolor
= Color (or something like that) but this seems not to work with the
Format-Wide.

Thanks you!
Cedric

I think you need to write your own Format-Wide function using Foreach-Object,
Write-Host etc.

Here is a Sample Script that will do it. One thing about this way is you
lose your ability to pipe.
Write-Host does not pass down the pipe and Write-Output does not do color.

Note:
$count = is how wide
$pad = How much to pad the name (if you have long file names)
$wide = how wide you want

Let me know if you want an explanation of anythin
======= CODE =======
# Get-ChildItemPretty.ps1
Param($path,[int]$count=1,[int]$pad=30,[int]$wide=3,[switch]$recurse)
if($recurse)
{
$list = Get-ChildItem $path -recurse
}
else
{
$list = Get-ChildItem $path
}
foreach($item in $list)
{
if($item.PSIsContainer -eq $true)
{
$color = "red"
if($count -lt $wide){write-Host
($item.name).PadRight($pad) -foregroundcolor $color -nonewline;$count++}
else{write-Host ($item.name).PadRight($pad) -foregroundcolor
$color;$count = 1}
}
elseif($item.Extension -match "exe")
{
$color = "blue"
if($count -lt $wide){write-Host
($item.name).PadRight($pad) -foregroundcolor $color -nonewline;$count++}
else{write-Host ($item.name).PadRight($pad) -foregroundcolor
$color;$count = 1}
}
else
{
$color = "White"
if($count -lt $wide){write-Host
($item.name).PadRight($pad) -foregroundcolor $color -nonewline;$count++}
else{write-Host ($item.name).PadRight($pad) -foregroundcolor
$color;$count = 1}
}
}

whoops.. I got your colors mixed up. Dirs will be red and EXE will be blue.
Easy to change though.

Here's a slightly more fast & dirty method that takes advantage of out-
string - it just converts the formatted table to a string, then
streams the result down the pipeline one line at a time:

gci . | format-table | out-string -stream | %{
if ($_[0] -match "d") {write-host $_ -fore cyan}
elseif ($_ -match ".exe") {write-host $_ -fore red}
else {write-host $_}
}

Not much you can do with the result, though. It would certainly be
nice if write-output could be colourized as well.

-Hecks

You can preserve the pipline by using $host.ui.rawui instead of the
write-host CmDlet.

for an example see :

I knew of this, but it doesn't do the wide aspect he was looking for, but I
like the way you do the color and I like that it perserves the output. I
think I will combine the two scripts. I will post soon.

Try this version out. Compliments of mostly MoW (posted here at the bottom

Hi Brandon.

I like it,
but if $columns * $max doesn't fit $Host.UI.RawUI.WindowSize.Width exactly
the columns don't match.

I think you'll need a column counter to insert a crlf
