       block - temporarily block delivery of events

       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.
