README
parce
Parce is a parser and lexer generator, where the grammar and the parse tree are the same data structure. It is similar to ANTLR, but the grammar is written in Rust code, not a special DSL.

Features
Lexer Features
- Regex-like repetition operators
- The usual
*,+, and? - And also
{n}(exactly n),{n,}(n or more), and{n,m}(between n and m inclusive) <- ANTLR doesn't have those :)
- The usual
- Lexeme nesting
- Regex-like character classes
- Skipped lexemes
- Fragment lexemes
- Modal lexers
- unlike ANTLR, lexemes can be active in multiple modes
Parser Features
Future plans
- Semantic predicates
- left-recursive grammar re-writing like ANTLR, using semantic predicates
- Data post-processors
- multi-threaded lexing and parsing.
