fsw is a tool for recursively watching the current working directory and running a command when its contents change.

It's integrated with Git, so it won't rerun the command if an ignored file changes.

Why? Well, I quite like the workflow that sbt's tilde (~) operator provides, and I wanted a reliable mechanism to do the same thing with other tools.


You can find static binaries for Linux and macOS on the Github Releases page.
