reg exp in bans lua

[Pirre]

I tried to use +bannickre and +banmsge in development code, using:

+banmsgre 30 <.*\n.*\n.*> some reason
+bannickre 1440 <.+(?<!(\[DS[1234]\]|\[AK[12]\]))> some reason

As in the above example, I want to ban people writing multi-newline messages and force a certain username format. In my opinion and according to ADCH++ documentation, those regular expressions should work, but they don't. How can i use regular expressions in this functions properly? I also tried with Lua patterns, to no effect. Please tell me how can I use those functions...

shewing my previous comment, seems that re is based on the lua string.match(patern) if so this is a bug so changing it to a bug

ps lua regexp http://www.wowpedia.org/Pattern_matching seems to work, ifi am wrong someone correct me please ....

Indeed, I have managed to solve my problem with Lua patterns:

+bannickre 1 <[^%]]$> some reason
+bannickre 1 <[^1234].$> some reason
+bannickre 1 <[^SK]..$> some reason
+bannickre 1 <[^DA]...$> some reason
+bannickre 1 <[^%[]....$> some reason

and so forth (exceptions, etc...)

However, I've encountered anoter issue:
+banmsgre 10 <%>%>%>> some reason
<Hub> Messages that match "%" will be blocked (Level: 10) (Reason: %>%>> some reason) (Expires: never) (Bans for 10 minutes)

+banmsgre 10 <%>%>%>> some reason 0
 <Hub> Messages that match "%" won't be blocked anymore

So, it looks like its not posisble to use patterns that include the ">" delimiter, even with an escape character. Other tested symbols, like "<", "*" and "%s", do work.

Including POSIX regexes in the next release would be a great feature :).

Tested one more:
+banmsgre 10 <%W%W%W%W%W> some reason
<Hub> Messages that match "%w%w%w%w%w" will be blocked (Level: 10) (Reason: some reason) (Expires: never) (Bans for 10 minutes)

+banmsgre 10 <%W%W%W%W%W> some reason 0
<Hub> Messages that match "%W%W%W%W%W" are not being blocked

+banmsgre 10 <%w%w%w%w%w> some reason 0
<Hub> Messages that match "%w%w%w%w%w" won't be blocked anymore

So, upper case set-complement, as shown in http://www.wowpedia.org/Pattern_matching, also does not work.

Today i have experimented with
+banmsgre [^%w%.][^%w%.][^%w%.][^%w%.] some reason

I don't know if this is intended, but the pattern matches diacritical signs, like ą, ę, ś, ć, ł, ż, ź.

Extending [^%w%.] to [^%w%.ĘęÓ󥹌śŁłŻżŹźĆćŃń] solves the problem, but i wonder how it behaves with other diacritics or other alphabets. Probably a Lua issue, but nevertheless worth mentioning.

[Pirre (pierreparys)]

For problems with those expressions you best use forums regarding Lua and their patern matching.

The lower case was done intentialy to make it working for a user not knowing so much about lua and who doesnt want to write 60 lines of posible matches to block 1 search or msg

As soon the documentation is update and a correct example is puted there this bug will be closed :)
