Initialization and termination rules |
You can write rules that perform initialization and termination functions for your program using the process-start
and process-end
rules.
When your program runs, all process-start
rules are performed in the order in which they occur in the program, followed by all process
rules, in the order in which they occur, followed by all process-end
rules. (Naturally, find or markup rules invoked as a result of code in any of the process-start, process, or process-end rules will also fire, as appropriate, in this sequence.)
You can do anything in a process-start
or process-end
rule that you can do in a process
rule, however, as a matter or practice, process-start
and process-end
rules are intended specifically for initialization and termination code. They are particularly useful in include files where you need to have code in the include file execute before the main program code executes.
OmniMark also supports two other pairs of initialization and termination rules, find-start
and find-end
, and document-start
and document-end
. These rules are supported for compatibility with older versions of OmniMark. In new code, you should use process-start
and process-end
rules for initialization and termination code.
The order of execution of these rules is:
