doorgan/sourceror

Sourceror is an Elixir library that provides tools for parsing, traversing, and manipulating Abstract Syntax Trees (ASTs). It offers a high-performance zipper implementation for efficient code navigation and modification, alongside utilities for code formatting, normalization, and patch generation. The system also includes a vendored Elixir parser to support newer syntax features and enable precise source code manipulation.
