chpal -- Palette changer for ComputerCraft 1.8 and later

chpal is a cool program that lets you load and export palettes with the new features of ComputerCraft 1.8.



Download

pastebin get 1XBzKKrT chpal

Usage

chpal <path>

Change palette to the palette in path.

chpal --export <path>

Exports the current palette to path.

chpal --reset

Resets the palette to the default ComputerCraft palette.

Palette format
The palette format chpal uses is a limited version of the .Xresources format.
An example palette entry is

*.color0: #000000

The only criterium for an entry is

*.color<n>: #<hex>

Example palettes
You can find examples here.

pacpal

pastebin get xk8pjsJY pacpal

pacpal shows an image with all the colours, so you can get a quick look of all the colours.

I'm surprised this isn't getting much attention, it's a simple but useful tool, and those examples are pretty nifty, as well! Cheers for making this.

Thanks, glad it was of use to someone :D/>

Regarding lines 39-45:

-- oh god why
local imgpath = "/tmpimg"..math.random(1, 9999)
local handle = fs.open(imgpath, "w")
handle.write(imgstr)
handle.close()
local img = paintutils.loadImage(imgpath)
fs.delete(imgpath)

I've submitted a PR to ComputerCraft so that that could be simplified to:

local img = paintutils.loadImage(imgstr,true)

Thanks! That would make the paintutils API a little less bad :P/>

Not so bad that I wouldn't just avoid it completely, though.
