Event Monitor Sample Rule Base.
|
|
|
|
This is a source file to the Rule Compiler to demonstrate how to process
|
|
events.
|
|
|
|
----------------------------------------------------------------------------

NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE NOTE

|
|
There are *two* rule syntaxes used here, simple rules, and rule patterns.
|
|
|
|
Simple rules appear as ordinary C "if" statements, and follow the same
|
|
syntax rules. Example of a simple rule:
|
|
|
|
if ("x")
|
|
{
|
|
Say("You just typed \"x\"");
|
|
}
|
|
|
|
In Rule patterns, the test clause is enclosed by square
|
|
brackets [ ] instead of the parentheses ( ) used in simple rules.
|
|
Example of a rule pattern:
|
|
|
|
if ["d" "e" "m" "o"] ... (LCheckButton2)
|
|
{
|
|
Say("You just typed \"demo\"");
|
|
}
|
|
|
|
The pattern is a regular expression, with the following allowable
|
|
operators:
|
|

|
operator Marks Example
|
|
------------------------------------------------------------------------
|
|
| Alternatives "a" "b" | "c" "d"
|
|
[ ] Optional sequences [ "a" "b" "c" ]
|
|
{ } Required sequence { "a" "b" | "c" "d" }
|
|
|
|
|
|
Note that required or optional (sub) sequences can always have alternatives
|
|
|
|
----------------------------------------------------------------------------
|
|
----------------------------------------------------------------------------
|
|
|
|
Note also that there are two forms of rules, "if" rules, and "and_if"
|
|
rules.
|
|
|
|
Rules marked with "if" are primary rules, and are automatically sheduled
|
|
to run whenever any of their primary events are scheduled.
|
|
|
|
Rules marked with "and_if" are secondary rules, and must be explicitly
|
|
scheduled from another rule or from the application. The "..." syntax
|
|
and the "then ()" function are used to schedule rules from within the
|
|
rule.base
|
|
|
|
See the document "Writing Rules In The Event Monitor" for details.
