GitHub's code navigation features "jump to definition" and "find all references" are now available for all Elixir projects on GitHub.
When you view an Elixir file on github.com, you can click on the name of a function, module, or macro to see its definition and its references within that repository. We use the tree-sitter library to find definitions and call sites in your code.
Special thanks to @the-mikedavis and the
tree-sitter-elixir team for contributing the queries that power this system.
Learn more about code navigation for Elixir and other languages in the GitHub documentation: Navigating code on GitHub.
Also, check out the tree-sitter library to learn how support for different languages is implemented.
