Flex development on Linux, what’s a good free environment? [closed]

I would like to develop Adobe Flex applications using Linux and a free environment. I’d prefer a free as in freedom alternative, but as in beer would work as well. 😉

Are any of you developing Adobe Flex rich internet applications using such an environment? Or should I face the “facts” that Flex Builder is an essential tool for Flex development and that I’m more or less lost without it?

Answer

I use TextMate to do some Flex hacking on my home computer (a PowerBook G4 which can’t run FlexBuilder) and I have no trouble writing applications. It depends if you are so used to IDE support that you cannot live without it. I like code completion, project management and the debugger in Flex Builder but I can live without it. TextMate isn’t free but any text editor that had code coloring for ActionScript would do for me.

I usually use ant to manage my builds and that is free. The Flex SDK is free. That is all you need plus a little patience.
