- ReleaseCandidat 3y agoThat's not possible, as Treesitter doesn't do for example type-checking (unification). It can be used as the parser to generate the AST with which you're actually doing the work.
- spinningslate 3y agoAgree, though not sure that's what the parent meant. I think they meant: 1. Some LSP implementations use Tree Sitter as the parser in their implementation 2. But it's only part of the implementation. It just generates the parse tree, on which various other LSP features are built, e.g. enhanced syntax highlighting, go to definition, ... Tree Sitter is pretty good for (1) because it was built specifically to cope with code that is (a) changing rapidly and (b) is, by default, not valid. So it has good error reporting and recovery.
