Does anyone have any tips for developing tree-sitter grammars?
I was about to ask for actual error assistance, but it seems to have magically fixed itself (though it’ll probably break as soon as I touch it). I frequently get wrong
NODE_MODULE_VERSION errors, which are a pain. Working on both the parser and how it runs in Atom at the same time seems impossible.
Should I have different versions of NodeJS installed or something? Am I able to develop the parser locally, and use this local version in the Atom package?
My current workflow is
- Make changes to tree-sitter parser and publish to NPM
- Delete the old version in
node_modulesin the Atom grammar package, and run
- Hope it works.
There are also frequent bugs in the syntax highlighting. For example,
The comment should not look like a string. (using this tree-sitter grammar and the unpublished GitHub version of this Atom grammar). Having a closing brace there is illegal, and throws a
MISSINGwhen I run
tree-sitter parse ..., but the syntax highlighting seems to have leaked.
