Grammar-Kit VS intellij-community

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...

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.

Also, no BuSL stupidity, they're all Apache 2 AFAIK: https://github.com/JetBrains/intellij-community/blob/idea/23...

And the "all you can eat" toolbox license is just a staggeringly good deal, IMHO, which also comes with a "you can keep your license forever, just no updates" which is way different from setting subscription-based licensing money on fire when your license expires. Whoever came up with that should be applauded because it really drives down my "what about" anxiety of paying subscription money for IDEs

I readily admit I am not familiar enough with fossil to know about the impedance mismatch, but I'll point out that https://github.com/JetBrains/intellij-plugins/tree/idea/241.... https://github.com/JetBrains/intellij-community/tree/idea/24... https://github.com/JetBrains/intellij-community/tree/idea/24... https://github.com/JetBrains/intellij-community/tree/idea/24... may a long way toward finding how they think about those operations

There is quite a bit going on in our view’s class, so we'll take it slow and go through its functions one by one, according to their importance. The first thing we need to do is to create the structure our items will fit into. com.intellij.ui.treeStructure.Tree seems to best match our needs, and that’s what we’ll use. In order to prepare it for what is coming, we need to configure it.

I think it's time to wrap it up. We've made a pull request to the IDEA developers, and I've accomplished the tasks I set out to do. I'm really happy to help the developers of my favorite IDE.

I had the same experience with OmniGraffle, https://www.omnigroup.com/omnigraffle

It just worked. There was support. I wouldn't dig a hole in the ground with my bare hands, why wouldn't I use good tools. Of course I would like to use F/OSS for various reasons.

The model I absolutely love is Jetbrains, their core product is OSS, Apache licensed. The whole thing, totally usable. https://github.com/JetBrains/intellij-community

The money I send their way does both, it pays for developers and it puts an amazing artifact in the world that others can use and learn from. If they weren't open source, I wouldnt pay for it. I don't know how many others are the same as me, but Jetbrains really deserves credit here.

and also FOSS (Apache 2): https://github.com/JetBrains/intellij-community (as well as PyCharm found in the "python" subdirectory)
