Flex: MXML syntax highlighting, autocomplete and bracket matching functionality on GNU/Linux?

Question

Has anyone been able to get syntax highlighting, autocomplete and bracket matching functionality on GNU/Linux for MXML files?

We are using Eclipse with Flex Builder for Linux (version alpha 5), but we can't edit MXML files on design view, and the text mode just shows the XML as plain text (not even syntax highlighting).

The official project from Adobe seems abandoned, do you know of any alternatives?

Answer 1

JetBrains just launched IntelliJ IDEA version 9. Which has Flex and Air support. Take a look at it.

Answer 2

So far, IntelliJ IDEA version 9 and Eclipse with Flex Builder seem to be the best solutions for this question.

We were using Eclipse 3.5, but haven't been able to use the MXML syntax highlight or autocomplete even with the patches. However, we could use these features with Eclipse Europa without patches.

The Design view for MXML doesn't work for GNU/Linux yet, afaik.

I hope this situation improves.
