Jon Siwek	98663fd534	Fix return value of hook calls that have no handlers. ... For this case, the return value is always true.	2012-12-18 15:31:50 -06:00
Jon Siwek	4e85fe0454	Change hook calls to only be allowed when preceded by "hook" keyword.	2012-11-30 15:39:00 -06:00
Jon Siwek	378ee699ff	Hook functions now directly callable instead of w/ "hook" statements. ... The return value of the call is an implicit boolean value of T if all hook handlers ran, or F if one hook handler exited as a result of a break statement and potentially prevented other handlers from running. Scripts don't need to declare hooks with an explicit return type of bool (internally, that's assumed), and any values given to (optional) return statements in handler definitions are just ignored. Addresses #918.	2012-11-26 17:09:29 -06:00
Jon Siwek	e0fb9eb2b2	Add new function flavor called a "hook". ... This new flavor of function behaves like a "synchronous event". See documentation for more details on usage.	2012-11-15 13:45:13 -06:00
