README
chloro
chloro is a minimal Rust code formatter.
Motivation
For when you want to format two source files in a consistent way, as fast as possible.
How it works
Using rowan from the rust-analyzer project, which can give both green and red trees. The latter are notoriously expensive, but a formatter should only need the former.
Proof of concept library/CLI to explore a fast and low memory code formatter [WIP], with use cases of code diffing in mind.
Rustfmt Conformance
Diff 'leaderboard' for how well formatting with chloro matches rustfmt, as tested on rust-analyzer's crates:
