Weird behavior with multiple reparse trigger states
|
Try the following:
| Code: |
#REGEX {(say)} {#COLOR white
#PCOL red %x1
#WIN debug {saw says}}
#COND {".*?"} {#CW cyan,hi
#WIN debug {saw quotes}} {regex|reparse}
#COND {\b(xxx|yyy)\b} {#CW magenta,hi
#WIN debug {saw bracketed %x1}} {regex|reparse}
#SH Todd says ~"Bar~" |
What you'll see in the debug window is:
| Code: |
saw says
saw quotes
saw bracketed 5 |
And then it will fail to fire again if you #SHOW again.
So, why does it stop firing, and more importantly, why does it match (xxx|yyy) in state 2? |

Confirmed. The trigger continues to fire for me in a blank session, so that must be something else in your scripts.
But I do see the behavior you describing and that looks like a bug. State two shouldn't be getting matched. |

Since I have recently been deep inside the multistate trigger code, I decided to take a quick look into this. Wow, this was a really obscure problem!
In CMUD, the #CW command needs to match multiple words on a line. So #CW needs to fire the trigger multiple times on the same line to determine what to color. In the case of a ReParse trigger state, the state of the trigger had moved to the next state (the xxx|yyy state), and when #CW in the .*? state called the trigger again to look for more matching text to color, the trigger was in a new state, which was actually causing the state to become corrupted with the wrong regex data. And once the compiled regex cache was messed up for the trigger, none of the states would work correctly.
So, this should be fixed in v2.0, and this bug could have caused weird side effects in any multistate trigger that also used the #CW command. Thanks for reporting it! |
