Right? > > Now I see why there is confusion. Tree-sitter only provide a “primitive” feature: the concert syntax tree, and it is not language-agnostic. You don’t get indentation for free, unfortunately. I wasn't talking about tree-sitter itself, I was talking about the facilities Emacs will provide based on TS. There will be in Emacs a function to calculate indentation using TS, right? And that function will be language-agnostic, like indent-line-function is, right?
