# E(a)rl

E(a)rl helps with your development by restarting your command when files change.

A file watcher based on things I liked about [nodemon](https://github.com/remy/nodemon) and [watchexec](https://github.com/watchexec/watchexec):

- When command exits, wait for changes instead of re-starting ad infinitum

The name is an acronym for "Execute Reload Loop", inspired by "Read Eval Print Loop". "Earl" is nicer to say than "erl", but "erl" is nicer to type on a QWERTY keyboard.
