There's also this one: https://drive.google.com/file/d/0BxB...ew?usp=sharing
Haven't used either of them though, so I can't comment on completeness or up to date-ness of it all.

Three years or so ago I changed "zscript.txt" to java/c++ style comments so it could be parsed more easily. There was even some doxygen files at one point. What I ended up using after this was Visual Studio with Visual Assist for auto-complete/syntax highlighting, which also nicely preserves the comments/documentation as well. IIRC you only have to change the file extension and about 8 lines or so to get it working. Not very lightweight for normal users, but easy if you already have these tools installed.

I also wrote a zscript preprocessor a while back which is kind of neat: http://armageddongames.net/showthrea...t-Preprocessor [edit]Crap, this link is also broken. D:

And here's a neat editor written in java with zscript language built-in: http://www.purezc.net/forums/index.php?showtopic=55636
