Hi,
my rooms are captured by the following pattern: &Roomname ~[&Roomexits~] (e.g. Throneroom [n,e,move throne]).
I have a problem as some special items in the rooms cause errors in the capturing (e.g. Bulletin Board [ 20 messages ], -> the "20 messages" comes with blank spaces at the beginning and end).

Is there a way to capture the normal room without firing on the bulletin board message? Possibly by "reversing" %s?

I tried the {^%s} pattern but that one does not help (Error in trigger pattern: {^%s} lookout assertion is not fixed length (17))
and the
&%x{roomexits} -> this one cannot cope with 2 word exits

You can do this with a regex. You'd insert this optionally matched string where ever it might appear in your normal string. The question mark at the end means the whole thing either matches once or zero times. So if it isn't there, it doesn't match. If it is there, then it will match:

(?:[\s*\d+\s+messages\s*])?

Hi, I solved it as follows - I tried the regex but I fear I have no experience with it, so I failed ..
Instead, I found a "walkaround" without regex.
Thanks nontheless ReedN!

<trigger name="Roomcapture" priority="597940" id="1306">
<pattern>^(*) ~[(*)~].$</pattern>
<value>#noop ***Checking, if the Room is actually a Message Board***
#if ((%2 =~ " (%d) notes ") OR (%2 =~ " (%d) messages ") OR (%2 =~ " (%d) note ") OR (%2 =~ " (%d) message "))
{#noop Ignore the Bulletin Board} {
#noop ***********Room found-Checking if the Room is a pool********
Mapper.Roomname = %replace(%1," (Abyssal)",)
Mapper.Roomname = %replace(@Mapper.Roomname," (Deep)",)
Mapper.Roomname = %replace(@Mapper.Roomname," (Shallow)",)
Mapper.Roomname = %replace(@Mapper.Roomname," (Empty)",)
#sub {%ansi(white)%1 %ansi(green)[%2]}
Mapper.Roomexits = %2
#TAG name @Mapper.Roomname ~[@Mapper.Roomexits~]
#TAG exit @Mapper.Roomexits
#ok
}</value>
</trigger>

I too would suggest a regex. The simplest being:
^(.*) ~[(( ?\d+ (?:notes?|messages?) ?)|.*)~].$
This pattern causes the regex to try to match the various notes and messages entries, when found it creates an additional capture. If it can't then it permits a general match capturing all of it.

You can then change your line:
#if ((%2 =~ " (%d) notes ") OR (%2 =~ " (%d) messages ") OR (%2 =~ " (%d) note ") OR (%2 =~ " (%d) message "))
{#noop Ignore the Bulletin Board} {
to
#IF (%3) {#noop Ignore the Bulletin Board} {

I would also suggest not using #NOOP for comments. This is a very practice from zMud; and will slow down the execution of your scripts considerably. CMud supports proper comments using //.
