How do I strip newlines from a string gotten from local chat?

[Domitan Redenblack]

I have a listener. Someone types:

      /123 mucking about \n \n \n

How do I strip these out of the message received by the listen handler?

Whatever is typed will always be received by the handler, you can't "preprocess" them.  Once they are in the handler though, a string trim will delete linefeeds: http://wiki.secondlife.com/wiki/LlStringTrim

If you could always predict that people were going to type \n and that it was always at the end of the message , then you could just write something like

integer idx = llSubStringIndex(data,"\n");

if (~idx){

     data = llGetSubString(data,0,idx-1);

}

That would take out everything following the first instance of "\n".  If \n is somewhere else in the string, though, you'd risk losing stuff after it. It would be safer to make multiple passes on the line, deleting one instance of \n on each pass.

Pete, are you sure that llStringTrim will remove a line feed that is typed in chat as \n? Won't it see \n as a literal string instead of an actual line feed?  (I can't get in world right now to test, so I'm just asking.)

Yes, "\n" on the chat bar will only be those characters and not an escape sequence. To insert a real newline in the SL viewer, we have to cheat a little and type a ¶ character, the same one we see in multiline paste. I hope that nobody ever wants to type a ¶ in chat!

this will strip text of "\n"

vStrMSg = (string)llParseString2List( vStrMsg, ["\\n"], [] );

this wil strip the text and replace them with real newlines...

vStrMSg = llDumpList2String( llParseString2List( vStrMsg, ["\\n"], [] ), "\n" );

Thanks Void, used this:

 

 

vStrMSg = (string)llParseString2List( vStrMsg, ["\\n"], [] );
