The README should explain everything pretty well, but basically this is fastmod (regex search-and-replace) with some non-regex extensions and implicit matching on whitespace. I've been using it instead of my editor's search-and-replace for a while now and am pretty happy with how it behaves (with some flaws noted in gh issues).<p>Let me know if you find this useful. If you're looking for other CLI refactoring tools there's a link list at the bottom of the README.
