progge.rs VS molten

Just tried to solve the "a farmer needs to move his fox, chicken, and corn across a river" riddle using the symbolic execution engine, and it worked! See here: https://github.com/skius/progge.rs/blob/master/analyzer-examples/fun/fox_chicken_corn.progge

I've been working on my program analyzer Proggers (see the previous post), and recently added symbolic execution into the mix - I thought some people here might find it interesting, or have other ideas!

Hi guys! I'm happy to finally share my project of the past few months with this community! Proggers is intended as a playground for me/other interested people to play around with and learn about various static analyses.

I second looking at the rust compiler. It splits various AST elements into a struct and enum, where the enum is a 'Kind' (eg. Expr for struct which contains an ExprKind enum). That allows things like line numbers and other common data to be easily fetched from the struct and variant-specific values can be stored in the enum, which can be pattern matched. I did a similar thing in a compiler I made a while ago here https://github.com/transistorfet/molten/blob/main/src/analysis/hir.rs

I managed to write an ocaml-like language compiler in Rust using llvm-sys (which uses the LLVM C API) without too much trouble. It may not be the fastest but it's fairly feature cobplete. The code is at https://github.com/transistorfet/molten
