< Note that this only works for commands that are executed when
sourcing the file, not for a function defined in that file.
:breaka[dd] expr {expression}
Sets a breakpoint, that will break whenever the {expression}
evaluates to a different value. Example: >
:breakadd expr g:lnum
< Will break, whenever the global variable lnum changes.
Note if you watch a |script-variable| this will break
when switching scripts, since the script variable is only
valid in the script where it has been defined and if that
script is called from several other scripts, this will stop
whenever that particular variable will become visible or
unaccessible again.
The [lnum] is the line number of the breakpoint. Vim will stop at or after
this line. When omitted line 1 is used.
