I'm a maintainer of a cli HTTP client with a text plain file format, Hurl [1]. I would like to begin to add support for various IDE (VSCode, IntelliJ), starting from syntax highlighting, but I have hard time to start.

I struggle on many "little" details, for instance: syntax error should be exactly the same in the terminal and in the IDE. Should I reimplement exactly the same parsing or should I reuse some of the cli tools parser? If I reuse it, how do I implement things given than, for instance, IntelliJ plugin are written in Java/Kotlin, while VScode plugin are Javascript/TypeScript, and Hurl is written in Rust...

Very hard to figure all when it's not your core domain,
