Regex question I believe
|
4078h, 3528m, 4156e, 10p, 17873en, 14460w, 1mo elrx-
4078h, 3528m, 4156e, 10p, 17880en, 14460w elrx-
I need to make a trigger that will read this prompt either way.. With or without the "1mo"
If the "1mo" is there.. I also want it to track the number.. the number can be between 1-5.. So basically
4078h, 3528m, 4156e, 10p, 17873en, 14460w, 1mo elrx-
4078h, 3528m, 4156e, 10p, 17873en, 14460w, 2mo elrx-
4078h, 3528m, 4156e, 10p, 17873en, 14460w, 3mo elrx-
or
4078h, 3528m, 4156e, 10p, 17880en, 14460w elrx-
Thanks in advance folks! |

It would help if you could tell us which parts of that prompt you want to capture. Also, does it always end with "elrx-", or does it sometimes end with something else? Does this prompt end with a carriage return, or does it wait there for you to type something or for more text from the mud?

Nope, don't need regex. 9.9 times out of 10, regex is completely unnecessary on the grounds that there's simply no advantage nor disadvantage to using it.
#trigger {%dh...bunch of unimportant stuff you probably already have figured out...({ | %a }) elrx-} {
// have to do the matching this way because if %match() doesn't match the specified pattern it just fills the variable with something random
$mo = 0
#if (%1 != " ") {
#call %match(%1," (%d)mo ",$mo)
}

#TR {(%d)h, (%d)m, (%d)e, (%d)p, (%d)en, (%d)w{, (%d)mo|} elrx-} {#IF (%7) {#SAY %7}}

Shalimar's should work, but in regex the optional operator is ? after a block of pattern in parentheses.:
| Code: |
\d+h, \d+m, \d+e, \d+p, \d+en, \d+w,(?: (\d+)mo)? elrx-
|
if %1 equals %null, then it didn't match, if it has a value, then it did. The neat thing about Shalimar's example is it simply won't fire when it doesn't need to, which is a bit more efficient. |
