pest

Grammars are defined in .pest files, keeping them isolated from code for better maintainability and readability, as shown in the ident_list example.

Automatically generates human-readable error messages that pinpoint issues in input, like unexpected digits, based on grammar rules.

Derives a Parser that returns nested token pairs, enabling easy iteration over parsed structures, demonstrated in the main example with ident parsing.

Runs on stable Rust and supports embedded environments by disabling default features, making it versatile for various project types.

Includes support for operator precedence handling in grammars, simplifying expression parsing without extra code.
