Grails gdoc editor support (esp IntelliJ)

Since Grails 1.2 there's a documentation engine included: gdoc. The documentation's syntax is based on the Textile format.

Is there some editor support for this? My first choice would be a plugin for IntelliJ, second option on for vim or gedit. Any hints welcome. I am totally a aware that the format is very simple by itself but having code coloring and content assi开发者_运维问答st would be really nice.

I'm not sure about Intellij, since many of us work on Macs we tend to use TextMate which has an excellent Textile plugin with completion, preview etc.

I know this is almost 3 years old, but just in case... I found that the Mylyn Wikitext plugin was useful for this in Eclipse. Just had to add the .gdoc file extension to it in under the properties.
