Hooks for notmuch
Hooks are scripts (or arbitrary executables or symlinks to such) that notmuch invokes before and after certain actions. These scripts reside in the .notmuch/hooks directory within the database directory and must have executable permissions.
The currently available hooks are described below.
This hook is invoked by the new command before scanning or importing new messages into the database. If this hook exits with a non-zero status, notmuch will abort further processing of the new command.
Typically this hook is used for fetching or delivering new mail to be imported into the database.
This hook is invoked by the new command after new messages have been imported into the database and initial tags have been applied. The hook will not be run if there have been any errors during the scan or import.
Typically this hook is used to perform additional query-based tagging on the imported messages.
