Regular expression
|
I'm having a problem with writing a regular expression for a prompt trigger I want to use.
Example of the text requiring triggering are
1234h, 2345m ae-
1234h. 2345m -
The following trigger matches the 1st 2 variables (1235 & 2345):
^([0-9]+)h, ([0-9]+)m
The problem I have is the character(s) or not, preceding the "-". ^([0-9]+)h, ([0-9]+)m ([A-z]+)- will capture the characters but only if any exist.
I would like to a trigger to match even if there is nothing preceding the -.
Once I get a value for the 3rd variable (it can include the - btw) I can then search within the variable for characters to determine what.
Thanks |

| Code: |
| #REGEX {^([0-9]+h, ([0-9]+)m ([A-z]+)?-} {Do whatever here. It will match %3 if it's there, and not bother the trigger if it's not there.} |
