watchman

A service that watches files, and triggers actions when changes occur. More information: https://facebook.github.io/watchman/docs/cli-options.

• Start watching a directory for changes:

watchman watch {{path/to/directory}}

• Add a trigger to run a command when files with a specified filename pattern in a watched directory change:

watchman -- trigger {{path/to/watched_directory}} {{trigger_name}} '{{pattern}}' -- {{command}}

• List all watched directories:

watchman watch-list

• Delete a watch on a directory:

watchman watch-del {{path/to/watched_directory}}

• List all triggers on a watched directory:

watchman trigger-list {{path/to/watched_directory}}

• Delete a trigger from a watched directory:

watchman trigger-del {{path/to/watched_directory}} {{trigger_name}}
