Awesome Pest. The Elegant Parser !Awesome (https://awesome.re/badge.svg) (https://awesome.re)

 (https://github.com/pest-parser/pest/)

▐ A curated list of resources, projects, and tools using or for the pest parser generator in Rust

pest is a general purpose parser written in Rust with a focus on accessibility, correctness, and performance. It uses parsing expression grammars (or PEG (https://en.wikipedia.org/wiki/Parsing_expression_grammar)) as input, which are similar in 
spirit to regular expressions, but which offer the enhanced expressivity needed to parse complex languages.
