astexplorer

it isn't rocket science, but https://github.com/fkling/astexplorer significantly raised my standard of what a readable, modifiable, nontrivial react/redux codebase could look like. bonus that astexplorer is basically used by everyone in the js tooling ecosystem

From the paper linked to in the README, this is: "a new approach for building source-to-source transformations that can run on multiple programming languages, based on a new way of representing programs called incremental parametric syntax. We implement this approach in Haskell in our Cubix system, and construct incremental parametric syntaxes for C, Java, JavaScript, Lua, and Python." http://www.jameskoppel.com/files/papers/oopsla18main-p221-p.... --- A couple of (somewhat) related projects I came across recently: AST Explorer https://github.com/fkling/astexplorer/blob/master/README.md Sparser the Universal Parser https://github.com/Unibeautify/sparser#readme What these have in common is that they include a collection of parsers, which represent programs in a language-agnostic data structure.
