The rest of the +// parser is in dhall_core. This separation is because compiling the +// grammar-generated parser is extremely slow. Eventually, the whole parser +// should probably be moved to here. +// See the https://pest.rs documentation for details on what this crate contains. +// The pest file is auto-generated and is located at ./dhall.pest. +// It is generated from grammar.abnf in a rather straightforward manner. Some +// additional overrides are done in ../build.rs. +// The lines that are commented out in ./dhall.pest.visibility are marked as +// silent (see pest docs for what that means) in the generated pest file. +// The abnf file has quite a lot of modifications compared to the one from +// the standard. Hopefully those changes should be merged upstream, but for now +// feel free to edit it to make parsing easier. include!(concat!(env!("OUT_DIR"), "/grammar.rs")); |
