24 alternatives to Codegen – OSS Python Library for Advanced Code Manipulation
Hey HN! We've just open-sourced Codegen (https://github.com/codegen-sh/codegen-sdk), a Python library for manipulating Python + JS/React codebases. Codegen was engineered backwards from real-world, large-scale codebase analysis + refactors we performed on multi-million-line enterprise codebases. It provides a scriptable interface to a powerful, multi-lingual language server built on Tree-sitter. We realized that many code transformation tasks that impact large teams - refactors, enforcing patterns, analyzing control flow - are fundamentally programmatic operations.…

Hey HN! We're excited to introduce Codegen - the IDE for Refactors. Codegen leverages static analysis to parse your codebase "graph", then wraps this in a high-level python SDK to enable safe & instantaneous codemods. We bundle this with an online editor/execution environment and closely coupled chat assistant in an online IDE. We focus on programming tasks on huge enterprise codebases where: - the output state is known (and easy to verify) - the "blast radius" is large - the difficult part is getting your codebase into the right shape. Codegen provides an AI-accelerated workflow for…

Hi HN, I’m here to show you a new codemod library. In case you’re not familiar with the term "codemod", here’s how it was originally defined AFAICT: > Codemod is a tool/library to assist you with large-scale codebase refactors Codemods are awesome, but I felt they were far from their potential, and so I’m very proud to show you all an early version of a codemod library we’ve built called Codemodder (https://codemodder.io) that we think moves the "field" forward. Codemodder supports both Python and Java (https://github.com/pixee/codemodder-python and…

Hi HN! This is a little site I put together while learning the Elm language as part of a hackathon at my work, I thought you might enjoy it. Be sure to click the `(source)` buttons next to the graphs: you can edit them interactively & write your own queries against the entire data set. The syntax isn't well documented yet, but you can probably get the general idea pretty quickly based on the examples there. If you like it, have questions, etc. let me know! If folks think this is cool, maybe I can get it turned into a legit project. :)
