Zugg Software :: View topic - matching a blank line in a conditional trigger?

Newbie Joined: 09 Feb 2006 Posts: 4 Location: USA

I capture my mud's various chat lines and send them to child windows. Usually (but not always) the chat is followed by a blank line. The blank line does not contain any spaces - it's just a crlf (or maybe a lf... not really sure how to tell the difference Wink

) The trigger below matches the text, puts it in my "Shout" window, and gags it in my main window, but the blank line after the chat still causes a line feed in the main window. Is there a way to match and gag the linefeed after the chat?

Here's the trigger:

#REGEX {^(?:>\s)?(\w+) shouts:(.*)$} {#GAG;:Shout:#SAYPROMPT {%ansi( bold, cyan)%1": "%ansi( bold, grey)%2}} "Chat Triggers"
#COND {^ +(.*)$} {#GAG;:Shout:#SAYPROMPT {%ansi( bold, grey)" "%1}} {looppat|prompt|regex}

Here's an example of something that matches. (The multiple lines is how my mud formats it and the reason for the #COND in the trigger. The periods at the beginning of the second line are spaces on the mud. I just couldn't get spaces to format correctly in this message.):

MRC shouts: Hey - Can anyone help me with this
. . . . . . . . . . trigger?
<blank line here>

Thanks!

The blank line can be matched with either ^$ or $ (one of them does not work within #CONDITION even though it works in a normal single-state trigger). I'd include it as a WithinLines=1 condition. The WithinLines option would invalidate the condition once the next line of text came in, thereby resetting the multi-state trigger back to state 0 automatically (if there happened to be more states after the blank line, it'd cycle to the next one).

Thanks - that worked perfectly.

Here's the new trigger in case anyone else finds it useful.

#REGEX {^(?:>\s)?(\w+) shouts:(.*)$} {#GAG;:Shout:#SAYPROMPT %ansi( bold, cyan)%1": "%ansi( bold, grey)%2}} "Chat Triggers"
#COND {^ +(.*)\n?$} {#GAG;:Shout:#SAYPROMPT {%ansi( bold, grey)" "%1}} {looppat|prompt|regex}
#COND {^$} {#GAG} {within|param=1}

Are the various trigger options (like withinlines, looppat, etc) documented somewhere? I'd like to figure out exactly how they all work, but couldn't find them in the online docs anywhere.

yeah, they are in there. If I recall, you can reach them via a hyperlink in the helpfile for #TRIGGER. In the syntax line the word "Options" is hyperlinked.

Also see the Advanced Triggers article from the ZMud library, which explains 'em in more detail.
