Hey all, below is my hyperlink trigger that worked in zMud, but I cant get it to work in cMud, could you have a look please? cMud reports an unmatched braces error. Be buggered if i can see it.

pattern: (%q)({http://|ftp://|telnet://|www.}%x)(%q)

script : #SUBSTITUTE {<A '%quote(%2)'>%1%2%3</A>}

much thankies :)

lovely, while tring to sort my classes into packages (the move function doesnt work) cmud crashed, corrupted the settings file, and the layout file.. 5 hours of work gone. much annoyed.

Yup, beta software does that. Backup, backup, backup, but you already knew that. Wink

yup :) i did know, and i didnt do it lol

its not a massive setback, i was just excited that id gone more than 3 hours without it happening this time.

odd, woudlnt let me reconnect to the charactor even with a totally new session created.. so reinstalled cmud, and no problem, even with the old files.

much oddness.

crycry, try marking the brackets <> with ~ to quote them, or using %concat() to merge everything.

I thought that too Raven, but no joy at all.. but will try the concat idea. thx :)

The < and > characters shouldn't be treated as special characters in CMUD, so I'm not sure the ~ is needed. This change was made specifically to allow HTML/MXP syntax without having to escape all the brackets.

What I think is happening is that the > character after the %quote function is getting interpreted as a "greater than" logical test. In CMUD, it's more important to put quotes around literal strings, and to use the %concat function like The Raven suggested.

I'll still put this on the bug list because it shouldn't be treating > as a greater-than character in this case and it's really a parser bug.

Perhaps, since quoting portions of text is more important now in CMUD, you could provide some syntactic sugar for the %concat() function? We need a less verbose way to use it, since we use it so often now.

You need a concat symbol... like & in Basic, or + in Perl. Can you overload the + symbol, so if either side of the operator is a string, it becomes a concat operator?

Actually, you *can* use the + in CMUD for concat (and also in zMUD I believe).

#SHOW %eval("a"+"b")

will display "ab"

However, when I tried it in the above #substitute command, it still gave an error, which is probably related to the same parser problem that gives an error for > when it shouldn't.

So yes, there is a shortcut to concat, but it seems to have trouble in some situations.

But can you use the + in braces, without the %eval()? If we put () around it will that work (I think () = %eval)

excellent, thanks guys for the help. im not overly worried about it working right now so ill wait for you to iron out the parser bug. Thanks again.

your all a whole lot cleverer than me thats for sure, thanks lots.

i tried that zugg and it worked but put a +{ }+ around the link. i tried #sub ("<A '"%quote(%2)"'>"%1%2%3"</A>") and it worked fine. is this still legal and, more importantly, sensible?

Yeah, that will work, although I'll need to check on the extra {}...that's probably another bug. But the implied concat syntax that is working with () is also supposed to work for {}, so you can certainly use that as a work-around until the {} is fixed.
