watchman

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

• Infer the root directory of the project containing the specified directory, and watch its files and sub-folders for changes:

watchman watch-project {{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 and its associated triggers:

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

• Delete all watched directories and triggers:

watchman watch-del-all

• 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}}

• Temporarily stop watchman, until the next time you call a watchman command:

watchman shutdown-server
