Pansies Functions with Parameter type `RgbColor` Error on `X11ColorNames`

I was running into errors when I type'd my functions as [PoshCode.Pansies.RgbColor]

$p = [PoshCode.Pansies.Palettes.X11ColorName]'maroon'
New-Text 'test' -fg $p

New-Text 'test' -fg ([string]$p)

Cannot bind parameter 'ForegroundColor'. Cannot convert value "Maroon" to type "PoshCode.Pansies.RgbColor". Error: "Invalid cast from 'PoshCode.Pansies.Palettes.X11ColorName' to 'PoshCode.Pansies.RgbColor'."

Cause

New-Text from[PoshCode.Pansies.Commands.NewTextCommand] can't coerce [Palettes.X11ColorName] to [RgbColor] -- even with valid names

Fix

Wrapping [string] first, works.

-fg ( $m.X11ColorName ) Works with -fg ( [string]$m.X11ColorName )

Test Code / How to Reproduce

$m = [PoshCode.Pansies.RgbColor]'maroon'
$x11 = [RgbColor]'maroon' |  % X11ColorName

# ok
[RgbColor]'maroon'

# ok
New-Text 'test' -fg 'maroon'

# ok
New-Text -fg (  [string]$m.X11ColorName) 'test'

# error
New-Text 'test' -fg $x11

New-Text: Cannot bind parameter 'ForegroundColor'. Cannot convert value "Maroon" to type "PoshCode.Pansies.RgbColor". Error: "Invalid cast from 'PoshCode.Pansies.Palettes.X11ColorName' to 'PoshCode.Pansies.RgbColor'."

Maybe your use-case is different than the example here, but I dont think you need to cast the color:

May 24 '22 17:05 aldrichtr

I'm sure we can add an explicit cast constructor. I definitely would like to be able to add tabcompletion for X11ColorName to all the RgbColor parameters ... (hmmmm).

The goal is that this should work:

[PoshCode.Pansies.RgbColor][PoshCode.Pansies.Palettes.X11ColorName]::Maroon2

Aug 17 '22 05:08 Jaykul

Ok, I pushed and released (2.5.0 and) 2.6.0 with this fixed, so you can cast X11ColorName enum values to RgbColor. In 2.6.0 I also added an ArgumentCompleter implementation to X11Palette, so you can get tab-completion of color names:
