- Using Hooks with Serial Numbers
-
- One of the neat things about ON hooks is that multiple hooks of the same
- type may be given different priorities. A serial number may be any number,
- positive or negative; zero is the default and should not be used directly.
- The numbers themselves don't really matter, rather their relation to other
- serial numbers is what's important. For example:
-
- on hook "*" echo foobar
- on #-hook -5 "*" echo booya
- on #-hook 5 "*" echo yadda yadda yadda
-
- Then, when any HOOK command is issued, the following three lines will be
- displayed, in this order:
-
- booya
- foobar
- yadda yadda yadda
-
- In general, it is always advisable to use serial numbers, if for no other
- reason than to prevent hooks from conflicting with each other. This is
- particularly true of the TIMER hook, which should always use serial numbers.
