24 alternatives to Codemodder – A new codemod library for Java and Python
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…
Codemodder is a library for large-scale codebase refactoring that works with both Java and Python. It takes a different approach from traditional codemod tools by separating the logic for finding code from the logic… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Codemodder – A new codemod library for Java and Python launched in 2024; newer entries below may have overtaken it.

I've been building a tool that changes how LLM coding agents explore codebases, and I wanted to share it along with some early observations. Typically claude code globs directories, greps for patterns, and reads files with minimal guidance. It works in kind of the same way you'd learn to navigate a city by walking every street. You'll eventually build a mental map, but claude never does - at least not any that persists across different contexts. The Recursive Language Models paper from Zhang, Kraska, and Khattab at MIT CSAIL introduced a cleaner framing. Instead of cramming everything into…

Hello HN, I'm releasing Hyperdiv (https://hyperdiv.io), a framework for rapidly developing reactive browser UIs in Python, with immediate-mode syntax and using Shoelace (https://shoelace.style) as its built-in component system. This short coding video will give you a good idea of what it is: https://www.youtube.com/watch?v=4XJKfxaqvGE I wrote a brief article about the motivation and approach: https://hyperdiv.io/intro.html Hyperdiv doesn't aim to compete with serious full-stack frameworks. The core aim was to make it easy and fast to…

Code Mode▲144I’ve been testing a simple idea inspired by Apple/Cloudflare/Anthropic: LLMs are far better at writing a small program than coordinating multiple tool calls. So instead of giving the model 10+ tools, I exposed one: a TypeScript sandbox with access to the same interfaces. The model writes a script → it runs once → done. What changed - +68% reduction in token use - No multi-step drift or retries - Local models (Llama 3.1 8B / Phi-3) became much more reliable Repo: https://github.com/universal-tool-calling-protocol/code-mode Curious whether others have seen…

Shelon: https://github.com/housni/sheldon It's not a framework, it's a library. It attempts to mimic function names in Python. Most functions work in Bash 4.3+ but there are those that work on older versions. The 'help' target in Makefile is on crack! Check the issues in that repo for upcoming features. Useful for DevOps Engineers or anyone who has to write Bash scripts.

Codebased combines Tree Sitter for code awareness (find functions, data structures, constants, etc. not just lines of code), full-text search using SQLite, and semantic search using OpenAI embeddings + FAISS. Despite being implemented in Python, supporting semantic search, making multiple API calls for embedding and re-ranking, it is faster than ripgrep for runng searches against the Linux kernel (takes ~1 second vs. ~2 seconds, obviously depends on system, temperature, time of day, tidal forces, etc.) Up next: - A Perplexity-like agent for interpreting results, making multiple follow-up…
