[2.25] Possible bug, but irritating problem nonetheless
|
To start off with, this is what I see when I type "bigmap" on Aardwolf while on a continent.
| Code: |
~~~~~~~~~~~~#####~~~#?~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~########~##|#~~~~###~~?#~###~#~####^^^?~~~~~~~~~?~
~~~~~~~~~~####?..####|######################^^^^~~~~~~~~~~#~
~~~~~~~~~#####...####|####?################^^?^#^###~~~~~~~~
~~~~~~~########################?#*####*##?###^^^^~~~~~~~~~#~
~~~~~~~##############################----------?^########~#~
~~~~~~~###########################----#######^^.##########~~
~~~~~~#########################################.####### .~~~
~~~~~##*%*#########..#############****###*##?##.######...##~
~~~~~###*########.....#.#########******#^^#####.###....####~ |
My mission? To create a trigger that'll tell me the position of each ? on the line. For instance, if I do:
| Code: |
| #SHOW %pos(?,"~~~~~~~~~~####?..####|######################^^^^~~~~~~~~~~#~") |
the MUD should return:
However, it doesn't. In fact, it returns "10" as the value. Why? Because even though it's a string, it still treats "~~" as just "~". So what CMUD is doing is checking the following:
| Code: |
| ~~~~~####?..####|######################^^^^~~~~~#~ |
As you can see, it shortens the string considerably (especially if the entire string consists of nothing but ~).
In my script, I've tried %string(%1), %string(%quote(%1)), %quote(%1), and even tried %replace(%1,"~","."), all to no avail. The only way I've found to circumvent this is to go to Options -> Scripting -> Special Characters -> uncheck the Quote Character.
It's a bug, in my opinion. CMUD shouldn't be checking for quote characters within strings. It should accept it as is. I'm not sure, but it probably relates to the bug I pointed out regarding string lists and the = character (to recap, if you do #VAR var "**==blah==**", it stores ** as a key, with =blah==** as the value, even though it's quoted with quotation marks).

Can anyone check this out? Would like to see it solved.

Well If I am right the reason is isn't matching is because ~ is a special character in CMUD. The first ~ escapes the second so you have half the number of ~ when it matches. If you goto preferences and turn that off that it will match.

A workaround would be %replace(%1,"~","~~") but this might make it too long, if there is only one ~. for instance if your capturing #~~#~#~~
Your going to get #~#~#~ as %1, and if you do the replace you get #~~#~~#~~. It might help tho |

As you can see, I stated that in my first post. But if you look at the #GAGON bug post I mentioned, that's hardly a feasible option. It shouldn't be treating special characters as special characters when enclosed by quotation marks. The quotation marks say, "Hey, make me a string and leave everything else alone!"
Also, I shouldn't have to turn off my special characters to use my scripts.

I tried that too. Like I said, I tried every possible workaround for it. It doesn't work. *sigh*

Im not sure what your pattern is to capture that stuff, but perhaps if you put %%string(pattern) around it or %%qoute(pattern)

That's the thing - I'm not using patterns to capture anything. I'm pasting it directly into the command line. Like I said, if I do:
| Code: |
| #SHOW %pos(?,"~~~~~~~~~~####?..####|######################^^^^~~~~~~~~~~#~") |
The MUD should return 15. But it doesn't. So even just using it in the command, it fails to work.

Ah thats the problem, your posting into the command line. Have you tried doing something like
#ALIAS mapp {#SHOW %pos("?","%1")} and then doing mapp #~~~~#?##~##~
Or somehow actually capturing it with a trigger, not sure how you could do that though, knowing what the output looks like |

Or better yet, use an alias, and use #PROMPT to ask for the input, copy/paste it and store it to a variable then %pos() it.

Your first suggestion was close, Toxic. (The last couple, not so much.)
The trouble with the first suggestion was that you didn't escape the characters used for the substitution. It's a common foible.
| Code: |
| #SHOW %pos(?, %replace("~~~~~~~~~~####?..####|######################^^^^~~~~~~~~~~#~", "~~", "~~~~")) |
Make sense? |

But again, the fact is, I shouldn't have to make any changes. It's a string, not unquoted. And Toxic, I've also tried using an alias, and that didn't work. I should be able to just do
| Code: |
| #SHOW %pos(?, "~~~~~~~~~~####?..####|######################^^^^~~~~~~~~~~#~") |
and it work like it's supposed to. However, I'll keep your suggestion in mind, Larkin. Thanks for a workaround. :)

I'm sorry for stupid question, but why you guys want to substitute "~" with escaped "~~" ("~~" with "~~~~")? Charneus did not said that he cares about preserving the "~" in string. He only wants to know at what position the question mark is located. So why not use something like
%replace("~~~~~~~~~~####?..####|######################^^^^~~~~~~~~~~#~", "~~", "X"))? |

Either way works, the important part is that you replace ~~ at a time instead of ~ |

You're incorrect - neither way works. And no, I don't have a reason for it not working, but try it yourself and see. :P

I tested my code, and it -does- work. The extra ~'s get stripped out by the function, thus giving you the correct position in the string. Did you try it yourself?

Certainly Charneus is correct that CMUD shouldn't be parsing the ~ within a " literal string, so I have added that to the bug list.

Yes, I did. I never said yours didn't work. Was referring to replacing "~" with "~~" not working.

I am glad Zugg decided it counts as a bug. It used to be needed in zMud to do things like var="a~"b", but CMud has other support with the form of var="a""b". The whole handling of tildes was rather crazy, and I will be happy to see that confusion gone.
