  Search text using a grammar, lexer, or straight regex. Chain searches for greater refinement.

• regex

  91 3,336 9.1 Rust

  An implementation of regular expressions for Rust. This implementation uses finite automata and guarantees linear time matching on all inputs.

  

I also took a look at https://github.com/rust-lang/regex and actually found the regex parsing code ('(', '{', '*', '?' etc.) so that is a good start too.

  LR(1) parser generator for Rust

  

Hi! For one of my projects I am currently using lalrpop (https://github.com/lalrpop/lalrpop/tree/master/doc/calculator/src), which is far from complete, but has the basic syntax I was looking for. I took some examples and worked around some lexer stuff but I’m currently happy with it. If you use it and have Intellij stuff installed, you can also use a plug-in for highlighting and SOMETIMES error checking. Otherwise, even VSCode had a great plug-in for highlighting!
