A refactoring tool for Racket built on top of syntax-parse.

Use the Racket package manager to install in the installation scope.

raco pkg install --installation resyntax

The --installation flag (shorthand for --scope installation) installs packages for all users of a Racket installation and ensures resyntax is in your $PATH.

e.g.

% resyntax analyze --file coroutines-example.rkt
resyntax: --- analyzing code ---
resyntax: --- displaying results ---
%

See the documentation for more details on how to use resyntax.

Resyntax integrates with GitHub in two ways: an analyzer GitHub action that reviews pull requests, and an autofixer GitHub action that periodically creates pull requests cleaning up a repository. You can find reviews the Resyntax analyzer has left on GitHub pull requests "in the wild" using this search. To find pull requests created by the autofixer, use this search.
