* The ungram file is now taken from the rust-analyzer dependencies pulled in by bazel * the grammar parsing code is not published, so it must be taken directly from rust-analyzer code. That part should be less prone to be updated than the ungram file, so it does not necessarily need to be in sync with the rust-analyzer version is used elsewhere. * both need some patches. The former is patched during build, the latter during loading in `MODULE.bazel`.

This crate takes care of generating `ast.py` in the schema and `translate/generate.rs`
|
|
in the extractor.
|
|
|
|
It uses:
|
|
* `rust.ungram` from `ra_ap_syntax`
|
|
* a couple of slightly modified sources from `rust-analyzer` that are not published.
|
|
|
|
Both are fetched by bazel while building. In order to have proper IDE support and being
|
|
able to run cargo tooling in this crate, you can run
|
|
```bash
|
|
bazel run //rust/ast-generator:inject_sources
|
|
```
|
|
which will create the missing sources. Be aware that bazel will still use the source taken
|
|
directly from `rust-analyzer`, not the one in your working copy. Those should not need to be
|
|
update often though.
