IDEA support

[xepozz]

Hello, team.

During a weekend I've made a plugin for HHVM (especially for Hack lang) which uses LSP to highlight the code errors.
There're several cool features in the Hack, but it's not about it.
There were some problem on Mac, so plugin uses Docker setup to run hh_client --lsp on communicate with the IDEA through the stdio pipes.
Overall it looks good, but seems like LSP isn't as full as can be:

• Target navigation barely works
• Code completion is scant
• Documentation has no basic information PHPStorm provides in Dumb mode

Anyway, it is an interesting challenge to make Hack language support as powerful as all modern languages are in IDEA.
Should I continue? Is there anyone who's willing to see Hack support in IDEA / PHPStorm?

If so, can I count on the Hack team's support? For example, I'd add some markers to LSP output to have better control for Documentation, grammar parser is written in Rust, but the plugin uses JFlex + GrammarKit that are similar to Flex and Bison (from C), but written in Java and Kotlin and the parser architecture is different. That's why I wasted a weekend to re-write or find available grammar syntax converters, but they sucks.
