I recently came to PEG through [https://pest.rs/](https://pest.rs/) and wondered if Julia had this kind of packages. I came across this topic : [ANN: Automa.jl - a package to compile regular expressions to Julia](https://discourse.julialang.org/t/ann-automa-jl-a-package-to-compile-regular-expressions-to-julia/1586) which gives some insights of it, but I thought it would be better to open a dedicated thread.

```julia
- https://github.com/vonDonnerstein/StringParserPEG.jl
- (outdated) https://github.com/wdebeaum/PEG.jl
- https://github.com/andrewcooke/ParserCombinator.jl
- (outdated) https://github.com/abeschneider/PEGParser.jl

```

seem to have addressed this issue. Do you know other projects ?

(I’m new to this forum, so I can not post more than two links)

The second one you list is not current. Look to the first and third.
