  I get the sense that treesitter is more for syntax highlighting than for real parsing, since I raised this issue[0] a while ago and I don't think anyone's really interested in it (not really interested enough myself in tree-sitter to see if it can be fundamentally solved; solving it involves making almost all production rules in the grammar parametric over two booleans).

  Admittedly I haven't tested the TypeScript treesitter grammar, but I'd be surprised if the issue is fixed there. I've put together a sample file[1] that demonstrates various cases of these context dependencies. If I remember correctly, Sublime's highlighter was the best at handling these cases out of various editors I tried, though it still failed at some of the ones at the bottom involving multi-line function expressions within object literal keys. GitHub/gist uses treesitter, so you'll notice that sometimes the "REGEX" and "DIVISION" blocks are inconsistently coloured, but a correct parser should associate a colour consistently to them. Not demonstrated here, but inserting a multi-line comment in a file that is parsed incorrectly will throw the entire thing off.

• How to make `goto_next_test` and `goto_prev_test` work?

  I believe goto_next_test requires support from the tree-sitter parser, specifically tree-sitter-javascript in the case of JS and tree-sitter-typescript in the case of TS.

  Here is the tree-sitter grammar of Elisp:

  https://github.com/Wilfred/tree-sitter-elisp/blob/main/gramm... (approx. 200 lines)

  and here is the grammar of JavaScript:

  https://github.com/tree-sitter/tree-sitter-javascript/blob/m... (approx. 1200 lines)

  JavaScript evolved into a language of similar complexity as Perl 5 (the corresponding tree sitter syntax table counts almost 2000 lines, currently).

  Next, clone the Javascript grammar for tree-sitter from https://github.com/tree-sitter/tree-sitter-javascript and compile it with cc -shared -fPIC -g -O2 -I src src/scanner.c src/parser.c -o ~/.emacs.d/tree-sitter/libtree-sitter-javascript.dylib.

• Trying to implement language injection for template literals: CSS inside of ` `
  2 projects | /r/Atom | 31 Mar 2021

  I downloaded the tree-sitter-javascript repo, created a folder for a custom grammar package, and created a basic package.json file, but I have no clue what the Atom page is talking about regarding call_expression, and the addInjectionPoint code. ELI5?
