CMUD triggering with special characters
|
I would like to trigger off text that includes special characters and I am at a loss for how to tell CMUD something like an asterisk is just a normal character in this context 
for example, I want to trigger off the following line of text and grab the number following the asterisk and add it to a variable list. to make the pattern as flexible as possible I tried to only use the initial asterisk and the opening bracket as a reference
*423 [Mar 15, 2021] March Reboot (Gaborn)
| Code: |
<trigger priority="35130" id="3513">
<pattern>*(*) [</pattern>
<value>#var unreadnotes %additem(%1,@unreadnotes)
</trigger>
|
Thank you for reading  [/code][/b] |

Escape everything not a regular character...which will assure you get what you want.
<pattern>~*~(~*~) ~[</pattern> |

thank you very much. i tried both ideas and neither added to the list. i tried
and it worked. thank you for the help
your knowledge has inspired related questions:
Q. so the ~ character, it "escapes" the next character only? or does more than that?
Q. i have seen %d in use but dob't really understands what it is and how to use it properly. i have also seen %w. is this effectively the same thing? are these temporary variables?
thanks again |

Correct, ~ escapes (makes the parser ignore any special uses for) the character immediately following it. That is all.
In '#HELP #TRIGGER' there is a link to 'pattern matching symbols'.
I prefer to use typed wildcards to make for a tighter pattern.
* is the most greedy wildcard there is, any amount of any characters
%d matches unsigned numeric values
%w is for single words |

thanks again.
I am now working on the output side of this program and %pop is really nice, but I have just realize that I am sending 423 to the mud instead of read 423. So my thought is I need to include read in what the trigger is saving to the list, or I need to somehow %concat read and %pop (unreadnotes)
In hopes of concatenate read and 423 i tried the following. The fire but do not compile:
| Code: |
#var unreadnotes %additem (%concat ("read", %1),@unreadnotes)
#var unreadnotes %additem (%exec("%concat ("read", %1)"),@unreadnotes)
|
I then tried to concatenate read and %pop (unreadnotes)
| Code: |
#send {read }%pop (unreadnotes)
#send read %pop (unreadnotes)
#send read|%pop (unreadnotes)
#EXEC {%concat("#send read ","%pop (unreadnotes)")}
|
in most cases the above results in an error parsing command. It seems that trying to combine %pop with other functions appears to make %pop no longer see what is in the brackets as a variable. I am not working in xml much, usually the GUI, and normally the variable appears as a green when %pop likes it, then turns to black when you have combined it with other funtions.
It seems reasonable that both methods should work, I just can't find enough bailing twine to cobble this together from the help files an forums.
Thanks again for all your help. |

You seem to keep leaving a space between various functions and their opening parentheses.
This causes them to 'lose' the parameters you are trying to pass them.
Try:
#var unreadnotes %additem(%concat("read ", %1),@unreadnotes)
Or simply:
read %pop(unreadnotes) |

I stumbled on an answer to adding read and 423 together...it worky
| Code: |
| #var unreadnotes %additem("read "%1,@unreadnotes) |
if anyone has any ideas for mixing %pop with #send or something of that nature I think it will be very handy for something in the future :)
:EDIT
I posted this after midnight last night but for some reason I am only seeing it registering now...interesting
thank you shalimar, I will try to pay better attention to spacing, I appear to be adding it and leaving it out at random. |
