GraphLens: Transforming Repositories into Typed Graphs - Python, TypeScript, Go, and Rust in One Model

Many code comprehension tools eventually hit a wall. The first issue arises from the tedious cycle of searching, opening files, reading code, and navigating through imports. While functional, this method lacks the ability to recognize that a specific function in one file is the same as one in another, leading to inefficiencies and excessive resource consumption when using LLM agents. The second challenge is language limitation; tools may excel in one language but falter when dealing with polyglot systems where, for instance, a TypeScript frontend interacts with a Python backend. GraphLens addresses these challenges head-on. This open-source framework (licensed under MIT) intelligently parses the source project and normalizes its structure into a unified graph IR. Users can leverage this graph for various purposes, including dependency analysis, code navigation, identifying dead code, or providing precise responses to LLM agents without overwhelming them with unnecessary file data.
