State of this project

Looking at the last commit times, you may assume this project is abandoned. But I would rather call it done. I built this extension to aid in my work on Portal: Revolution, which has now released. I have added all the features I wanted and don't know what else I'd add. If you find any bugs, please feel free to report them. I want to keep this extension in a working state, but have no plans to add any new features unless I need them in another modding endevour.

Syntax highlighting

Available for:

• KeyValue files
  • .vdf .res .acf .kv .vmf .vmm .vmx
  • .txt files can be auto-detected as being KV files
• .vmt
• .fgd
• .qc
• .cfg
• lights.rad
• .vpc, .vgc
• .smd
• .fxc and _fxc.h

In-Editor compilation

Instead of juggling standalone tools or CLI programs, simply compile model (.qc) and captions (subtitles_english.txt) right inside of the extension.

KeyValue file auto-detection

In Source, many KeyValue files are saved with a .txt extension. Since not all .txt files should be treated as KeyValue files, this extension can auto-detect KeyValue files which end in .txt. Instead, KeyValue files are matched using a list of common keyvalue file names. (e.g.: gameinfo.txt, game_sounds_*.txt, subtitles_engish.txt...)
