How I Parse 14 Languages With One Function — Codewalk Deep Dives #1
Aakash Gupta discusses the development of a polyglot code parser that can handle 14 programming languages using a single function. The parser utilizes tree-sitter, allowing for efficient extraction of functions and classes from various codebases. This article is the first in a series that will explore the algorithms and engineering decisions behind the open-source AI code analysis tool, Codewalk.
- ▪The parser can handle languages such as Python, Rust, Dart, Java, Go, and C++ without needing to write separate parsers for each.
- ▪Tree-sitter is used to generate syntax trees from source code, providing a unified API across different languages.
- ▪Codewalk offers features like module detection, dependency graphs, and AI-powered code review.

I needed to extract every function and class from any codebase a user throws at me — Python, Dart, Rust, Java, Go, C++, all of them. I started with Python’s built-in “ast” module. It worked — for Python.
