diffsitter

Summary

diffsitter performs diffs on text files using the AST to compute the diff instead of using a naive text-based diff. This can give you more semantically meaningful diff information, which will prevent diffs from getting polluted by syntax differences, for example.

diffstter uses the parsers from the tree-sitter project to parse source code. As such, the languages supported by this tool are limited by the languages supported by the tree-sitter project.

Development

In order to develop for this project, you need to clone the project and initialize all submodules (each tree-sitter grammar is added as a subdirectory).

git clone
git submodule --init --recursive

This uses cargo with the cc crate, so you need to install rust and have a working C compiler (the tree-sitter grammars are written in C).
