Railroad (aka syntax) SVG diagram generator for pest parsers. It supports most (but not all) Pest grammar rules.
Library crate:
cargo add pest_raiload
The binary:
cargo install pest_railroad_gen
cargo run -- grammars/json.pest > json.svg
This results in:
This does what I need it to, so it is more or less "finished", but may get support for more Pest rules if I need them. Contributions might be accepted as long as they align to my vision for the tool.
