Having issues with a regex trigger
|
I'm not sure what's going on here... I've been having all sorts of issues with CMud that nobody else seems to have, and even re-installing doesn't seem to clear things up... my latest headache is a simple trigger attempting to capture variables from my battle prompt.
I have a trigger that captures my regular prompt which works perfectly, its pattern is:
| Code: |
\[Prompt: (\d+)/(\d+) (\d+)/(\d+) (\d+)/(\d+) (\d+)\|(\d+)\|(-?\d+) _([^_]+)_ (\d+)|(\d+)? (\sLdr: \d+)?$
|
It is, of course, flagged for regex, and it saves the numeric values to variables and works perfectly.
My battle prompt is slightly different, starting with "[BPrompt: " followed by more numbers I want to capture.
It seems no matter what I do, I cannot get the trigger pattern to work... I've even reduced it down to simply
and it won't trigger on my bprompt... even #ECHO [Bprompt won't trigger it... I don't understand the problem.
If I remove the "\[" from the trigger it at least fires, but that's part of the pattern I need it to match, and it works in the regular prompt trigger, so I cannot figure out what the problem is.
I really like a lot of the upgrades in CMud, but the unexplainable oddities and bugs make it a headache at times :( |

There's definitely a bug here involving unmatched but quoted square brackets. I'm not sure if this has been reported already, I have a tickling of a memory about it. It's even more fundamental than your problem:
| Code: |
| #regex {\[} {#echo test} |
will never fire except in one specific case. The compiled pattern is this:
| Code: |
0000 LINE 0 ; \[
0012 STR '\[]' |
which seems in error to me - an extra, closing bracket has appeared at the end. Echoing "[]" will set off the trigger, but no other pattern will. You can work around this for now by enclosing the quoted square bracket in square brackets, creating a range of only one character. Your pattern will look like this:
which is harder to read but which should work for now. |
