For people and teams developing mods and games with Valve's Source engine.
Syntax highlighting for various VDF sub-formats. Response rules, materials, QC, SMD, FGD, soundscripts, actbusy, soundscapes, VBSP and weapon scripts are supported.
This new release adds three new languages (FGD, weapon script, VBSP detail prop script) and changes the highlighting pattern of several established ones to a more logical hierarchy. It also includes all of the missing commands I've encountered since the last release.
To install, extract userDefineLang.xml to either:
