A Zed extension which adds syntax highlighting to the Oat language. The extension is powered by the tree-sitter-oat grammar.

The extension is added to the official zed extension catalog, simply search after an extension named Oat and install it.

Out-of-the-box, the extension matches all .oat files. If you want to match more file types, you need to edit the file_types mapping in your settings.json file.

To help developing this extension you need to install it as an dev extension. For this you'll have to have cargo installed and the wasm32-wasip2 target ond the stable rust toolchain set up. Additionally, you'll need to clone this repository to some location from where you can install it as a dev extension. A more detailed tutorial about this can be found in the Zed docs.

All tree-sitter queries for the extension are stored as git diffs which can be patched into the tree-sitter grammar. This patching automatically happens during the build phase.

To create a new query diff which can be patched, you need to copy all .scm files from this repository into the tree-sitter-oat/queries/oat directory or patch the diffs directly onto it.

Then, new diffs can be generated using

# Create git diff for a new file
git diff /dev/null queries/oat/<path-to-query>.scm > output.diff
# Create git diff for a file which was modified
git diff queries/oat/<path-to-query>.scm > output.diff

and then copied into the patches folder of this repository.
