TL;DR Command-line tool to run a command (and stop the old one) every time there's a filesystem change.
Take a command and a path, and run that command whenever there are any changes to those files. It kills previous invocations. It's like guard for anything. You never have to think "oh, I should run this," because what's running is always the latest thing.
It works especially well with IntelliJ's auto-save after x idle seconds (cmd + , then search for "save idle"), or any other auto-save IDE setting.
Intended for OSX.
brew tap mlbileschi/tap
brew install mlbileschi/tap/file_system_monitor
file_system_monitor --help
You may need to agree to the XCode TOS: sudo xcodebuild -license.
