Grammar-Kit VS otclient

I offer, again, my JetBrains GrammarKit counterpoint from the last time that assertion came up <https://news.ycombinator.com/item?id=38192427>

I consider the JetBrains parsing system to be world class and they seem to hand-write very few (instead building on this system: https://github.com/JetBrains/Grammar-Kit#readme )

- https://github.com/JetBrains/intellij-community/blob/idea/23... (the parser I'll concede, as they do seem to be hand-rolling that part)

- https://github.com/JetBrains/intellij-community/blob/idea/23... (same for its parser)

- https://github.com/JetBrains/intellij-community/blob/idea/23... and https://github.com/JetBrains/intellij-community/blob/idea/23...

- https://github.com/JetBrains/intellij-plugins/blob/idea/233.... and https://github.com/JetBrains/intellij-plugins/blob/idea/233....

I want to start adding support for Lua derivatives to my IDE (which adds static type checking to Lua - inference, structural & nominal types, generics etc. (Luanalysis - https://github.com/Benjamin-Dobell/IntelliJ-Luanalysis/)

I feel like plugin support would be best but I've no idea how that's supposed to work in the presence of a predefined grammar. There's also so many variants I don't think there's a good way to build composite grammar.

Does anyone have any ideas about how to extend language parsing? For reference, I'm using https://github.com/JetBrains/Grammar-Kit.

In IDEA, code generation by the GrammarKit plugin is mainly used to create a parser. Unfortunately, there is not much documentation about it and it is only presented in Tutorial and HOWTO.

Luanalysis is built atop https://github.com/JetBrains/Grammar-Kit, so can't eaisly be integrated in other languages servers.

Wow, amazing stuff. I love Lua, it was how I learned programming as a kid. Coincidently from the same world as the author. Open Tibia.

The author made a custom client (https://github.com/edubart/otclient) for the game that is still very much in active use by thousands of players. He's a very skilled developer.

Great to see AOT typed Lua, I know of the other solutions: Luau, Teal, TypeScriptToLua, Terra, etc., but this one is my favorite so far.

Love the simple compilation to C (and WASM support via Emscripten). Though Terra's JIT is enticing and good replacement for LuaJIT, this is for embedded systems, it's a good replacement for Lua PUC-Rio.

The World:

Open Source Engine and a very well edited open source client used for the Tibia OT servers and "Pokemon" RPG's you have seen online in the same style, It is the game r/TibiaMMO for those curious on the original game, never played it as I was a Ultima Online player in my early gaming days but it is obvious to anyone who knows about the game.
