In plain words
Crespo is a developer tool that transforms code into tree-sitter abstract syntax tree (AST) blueprints for use with large language models. Rather than feeding raw code to LLMs, it converts source code into structured AST representations that capture the syntactic structure of programs. The tool is designed for developers working with code analysis, generation, or manipulation tasks that benefit from more precise code representations than plain text.

Built Crespo because I kept hitting the context limit on multiple AI's. pip install crespo && crespo ./myproject The Problem When we paste the whole codebase to any LLM either it dosent understand fully or we hit the token limit. But when we try to give the context file by file it can't understand the relation between files and all these requires limited tokens that are wasted on making the AI understand the codebase rather than doing work. Instead of concatenating raw files, Crespo uses Tree-sitter AST parsing to extract only the structural aspects of your repository such as imports, classes, functions, module connections and generates a compact XML blueprint. This helps the AI understand…from github.com

I think there's many classes of application (particularly legacy architecture) that can benefit from these kinds of analysis tooling. My next post will be about composing all these together, an exciting project I call…
Structured output from LLMs without reprompting2023 · automorphic.ai · ▲174Built a tool for transforming unstructured data into structured outputs using language models (with 100% adherence). If you're facing problems getting GPT to adhere to a schema (JSON, XML, etc.) or regex, need to bulk process some unstructured data, or generate synthetic data, check it out. We run our own tuned model (you can self-host if you want), so, we're able to have incredibly fine grained control over text generation.

I built this software to help users who need to do static code analysis for C/C++ codebase. This can help you to explore the ASTs interactively. It can replace the Clang ast dump completely and also you can search the code/ASTs in a structual way. For example you can search a function which matches specific name or number of paremeters.

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
