I'm using the Yahoo's Vespa engine that involves a specific grammar in its configurations files (called SearchDefinition). I have access to the grammar of that configuration language through a JavaCC .jj file (see my issue on Vespa's Github).
My goal is to use that grammar to build a syntax-highlighting extension for VSCode according to VSC's documentation.
Problem: VSC's tool used to build a new syntax-highlighting needs a TextMate-like grammar and not a JavaCC-like grammar. My question is : how to convert a JavaCC grammar into a TextMate grammar ?
Thanks :)
