Greetings
Notepad++ has recently been treated to an updated UDL (User Defined Language) engine. I've managed to crash together a Syntax highlighting file that highlights different categories of commands differently and also includes code-folding on brackets. It's at
https://gist.github.com/CADbloke/7481998 - feel free to fork it, download it or even, if you're game, use it. Let me know which parts I broke.
Oh, you might want to change some of the colours - I never said I was a designer - see the attached screengrab.
The only caveat is that the highlighting for some of the vl..get and vl..put functions may look a little off - there isn't enough room in the lexer to put them all in - it gave up after a little over 53k character in one of the fields.
cheers
