File Watcher

This is a utility for watching a set of files in a directory, then triggering a build and restarting a process when those files change.

It will recursively traverse the directories from the current working directory, and watch for changes in any files that match the specified pattern.

It accepts three arguments on the command line.

• -build-cmd The command to rebuild your source.
• -run-cmd The command to run your process.
• -file-pattern The file pattern to monitor. This only accepts simple patterns at the moment, like *.go, manifest.json etc etc
