Natural-language code transformation as a Python library: generate_diff turns a plain-English goal into a unified diff, smartapply applies it resiliently. CLI included. Formerly gptdiff.

moulti

Moulti is a CLI-driven Terminal User Interface (TUI) displaying arbitrary outputs inside visual, collapsible blocks called steps.

mpatch

Applies diffs based on context, not line numbers. Useful for AI-generated code.

similar-rs

Rust-powered text diffing for Python: a fast drop-in replacement for difflib, powered by the similar crate

purepatch

Apply unified diffs and fuzzy search/replace edits in pure Python - the patch engine for code agents. No git, no patch binary.
