Ben, thank you for the attention. I held myself off elaborating further because the introductory content in the project's page does a much better job.
Tree-Sitter parses code and builds an AST out of the nodes. That same tree can then be smartly updated continuously by providing the locations where the code has changed, thus the cost and speed for re-evaluating the tree is much reduced, resulting in pretty much instant feedback and lower CPU usage. Tree-Sitter also is able to highlight even incorrect syntax that would otherwise break completely in regex-based grammars. More from the main author of Tree-Sitter: https://news.ycombinator.com/item?id=18349488 https://www.youtube.com/watch?v=0CGzC_iss-8 *Tree-sitter is already usable in Atom/Emacs *and that trend is very likely to be followed in all other editors. Neovim's progress is getting there quickly. *The problem*: Elixir is not scheduled to be supported officially by the Tree-Sitter team. *What I am proposing*: A grammar for Elixir to be written in Javascript. Here is an example grammar for Haskell: https://github.com/tree-sitter/tree-sitter-haskell/blob/master/grammar.js Or Ocaml: https://github.com/tree-sitter/tree-sitter-ocaml/blob/master/grammar.js More to be found in the parsers' page: https://tree-sitter.github.io/tree-sitter/#available-parsers On Friday, March 29, 2019 at 7:41:09 AM UTC-3, Ben Wilson wrote: > > Can you elaborate for those of us with less context?
