Watchman exists to watch files and record when they change. It can also
|
|
trigger actions (such as rebuilding assets) when matching files change.
|
|
|
|
Concepts:
|
|
|
|
- Watchman can recursively watch one or more directory trees (we call them
|
|
roots).
|
|
|
|
- Watchman does not follow symlinks. It knows they exist, but they show
|
|
up the same as any other file in its reporting.
|
|
|
|
- Watchman waits for a root to settle down before it will start to
|
|
trigger notifications or command execution.
|
|
|
|
- Watchman is conservative, preferring to err on the side of caution;
|
|
it considers files to be freshly changed when you start to watch them
|
|
or when it is unsure.
|
|
|
|
- You can query a root for file changes since you last checked, or the
|
|
current state of the tree.
|
|
|
|
- You can subscribe to file changes that occur in a root.
