# Just Another YAML Parser
Clone like `git clone --recurse-submodules ...`
## Running tests
Set up a virtual environment:
python3 -m venv env
On macOS and Linux:
source env/bin/activate
Or on Windows:
.\env\Scripts\activate
Install dependencies:
pip install -r requirements.txt
Run tets:
pytest
## Roadmap
- [ ] Debug parsing showing how each rule is applied
- [ ] Parsing *presentation* (text) into *serialization* tree
- [ ] Composing *serialization* into *representation* JSON
## Regenerating 1.2.2 productions.bnf
https://yaml.org/spec/1.2.2/ contains HTML for the spec, but [yaml/yaml-spec](https://github.com/yaml/yaml-spec.git) has the markdown source.
Run script `produce_bnf.py` which uses yaml-spec as a submodule to produce `productions.bnf`.
