block(1) fish block(1)

block

block [OPTIONS...]

block prevents events triggered by fish or the emit command from being delivered and acted upon while the block is in place.
In functions, 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 begin, if, while or for
The following parameters are available:
-l or --local Release the block automatically at the end of the current innermost code block scope
-g or --global Never automatically release the lock
-e or --erase Release 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.
