block prevents events triggered by
fish or the emit command from being delivered and acted upon while the block is in place.
block can be useful while performing work that should not be interrupted by the shell.
The block can be removed. Any events which triggered while the block was in place will then be delivered.
Event blocks should not be confused with code blocks, which are created with
The following parameters are available:
--localRelease the block automatically at the end of the current innermost code block scope
--globalNever automatically release the lock
--eraseRelease global block
# Create a function that listens for events function --on-event foo foo; echo 'foo fired'; end # Block the delivery of events block -g emit foo # No output will be produced block -e # 'foo fired' will now be printed
Note that events are only received from the current fish process as there is no way to send events from one fish process to another.
