I've run into a problem inserting special characters (more specifically "<" and ">") into strings in Zmud. What I'm trying to do is capture lines of text, and insert an HTML " " at the end of each line (the text is being stored in a MySQL DB). Right now my trigger looks like this:

#TRIGGER {^(*)$} {@Buffer = %concat( @Buffer, " ", "%1")}

(there is a seperate trigger that turns it off)

The problem is that the resulting string will not contain the whole tag, just the "br". I've tried escaping it (eg. "~<br~>") with no sucess. Any help would be greatly appreciated. Thanks.

First off, ZMud uses < and > to denote MXP (basically a subset of HTML, designed for MUDs). That's why it's getting parsed out. Not sure if this will work, but if you are not using MXP you can simply turn it off and ZMud should then stop stripping these characters.

The proper way to do this, though, is probably to use a function like %expand() to control what gets parsed and what doesn't.

Perhaps try as well:

Syntax: %literal(s)

returns the parameters untouched by expansion or evaluation

You could also just concatenate directly instead of relying on a function to do it. Another thing, don't include the @ prefix when creating a variable.

#TRIGGER {^(*)$} {Buffer = ~<br~>"%1"}

Disabling MXP doesn't solve the problem, but disabling forced variable expansion does. Although disabling it does work, it would make sense (and I could be completely wrong) that there should be a way to escape the characters. It just doesn't seem clean enough

%expand() also doesn't seem to make a difference. When the characters are stored in a string, they seem to behave differently then when as constant strings in a simple command.

eg)
#echo " "
Output:
 

@TempString = " "
#echo @TempString
Output:
br

The problem is that the " " has to be stored in a string, so that it can be passed to a database via my plugin. And since it is stored in a string, %literal(@string) just returns @string (not expanded).

I'm stumped, but turning off forced variable expansion seems to be a decent workaround. However if there is a way to escape the characters, I'd like to know (*wink at Zugg*). Thanks

@TempString = " "
#echo %expand(@TempString,1)

works fine for me.
