Excellent, well done!

I did make a few tweaks to this, though. For one I added def into the first keyword group, toolchain into the fourth, and into in the third.

I also added highlighting for regular expressions. So in delimiter 3 style: open=/ escape=\ close=/ and same colour as in delimiter 1 style.
