Which Javascript code editor supports plain text line numbering?

I need to add a text area that also has line numbering capabilities. I tried EditArea, but I couldn't开发者_开发技巧 make it work with text files. It would be ideal if it could highlight syntax for existing programming languages, but that would only be a side bonus.

The main thing I'm after is line numbering for whatever I paste in it. Please only list open source ones.
