SlickEdit is a heavy duty, commercial, crossplatform, multi-language
editor and IDE that has some Ruby support, but that support needs

they give other languages, SlickEdit could become the TextMate
alternative for Windows, Linux and even Mac OS X. It probably already
outguns TextMate for Java or C#, for example (I’m not a Mac user)
To encourage this I’ve set up a poll :
