Anyone interested in a tool helps to explore C++ ASTs

In plain words

This tool helps C++ developers perform static code analysis by providing interactive exploration of abstract syntax trees (ASTs). It replaces traditional Clang AST dumps with a more user-friendly interface and enables structural searching of code elements—such as finding functions by name or parameter count. Designed for developers working with C/C++ codebases who need detailed code analysis capabilities.

From the sources

ACAV (Aurora Clang AST Viewer) is an interactive Abstract Syntax Tree (AST) visualization tool for C, C++, and Objective-C, built with Clang and Qt. Given a JSON compilation database such as compile_commands.json , ACAV lets you open a real project, inspect the AST for a translation unit, and move directly between source code and AST nodes. Screenshot: ACAV displaying the file explorer, source-code panel, AST tree view, declaration-context panels, and log panel. ACAV addresses the gap between Clang's powerful front-end infrastructure and the practical difficulty of exploring Clang ASTs interactively. It is designed for real codebases rather than toy examples: it reads a JSON compilation…from uvic-aurora.github.io

  I built a small browser engine from scratch in C++Jan 2026 · github.com · ▲146

  Hi HN! Korean high school senior here, about to start CS in college. I built a browser engine from scratch in C++ to understand how browsers work. First time using C++, 8 weeks of development, lots of debugging—but it works! Features: - HTML parsing with error correction - CSS cascade and inheritance - Block/inline layout engine - Async image loading + caching - Link navigation + history Hardest parts: - String parsing(html, css) - Rendering - Image Caching & Layout Reflowing What I learned (beyond code): - Systematic debugging is crucial - Ship with known bugs rather than chase…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
