Process is a helper function for c/h/decho. It's contained in a table called Echos. Have you created your own Echos table?

The original question wasn't about coloring the prompt, it was about cecho eating angle brackets. (I've also just committed a fix to this to LuaGlobal. In the next Mudlet release, cecho will ignore anything in angle brackets if it's not in the color table. If it is in the color table and you want it...

sounds/x.wav or ./sounds/x.wav

I just put the sound files into the mudlet install directory rather than the profile. Then I can just do playSoundFile("x.wav")

Cecho does in fact have escaping using \, however \ is also an escape character in Lua. So if you're using a string in single or double quotes you'll need to use two.

Ex.

Should do it.

Ah, I see it now.

That.. makes no sense.
