is there an easy way to take a string that came from the mud into a variable list ?

if %1 = a handful of rubies
can I add it to a list variable so that
list[1] = a
list[2] = handful
list[3] = of
list[4] = rubies

Thanks

Yep.

List = %replace(%1," ","|")

You could also use %subchar if you like. You can then use %item to get an item back out of the list, and #forall to iterate over the list.

Nevermind... :) Figured it out...

The reason it's not reading the | as separators is because you effectively added a stringlist to a stringlist, which results in nesting (the stringlist being added is automatically surrounded by parentheses.)

If you don't want nested stringlists, you either have to add each individual item separately or perhaps use %replace() or %remove() to pull the parentheses out after the additem.

reason I did it that way, I was reading the docs for #additem, it said #additem aa 1|2|3|4 would work correctly... or I misread it... anyway, it works now.

Why not do

why loop, when you don't have to ?

List = %replace(%1," ","|") works just fine.

I'm working on something else now, but have run into an issue with %replace....

I'm sending a web address, with a get ...

so my webadr varable looks like this

www.web.com/add.php?name=a glittering ruby ring&worn=finger

so I take the variable and do this

webadr = %replace( @webadr, " ", "%20")

which should look like this

www.web.com/add.php?name=a%20glittering%20ruby%20ring&worn=finger

but instead, it looks like this

www.web.com/add.php?name=aglitteringrubyring&worn=finger

Any thoughts ?
Thanks

The %replace actually works fine, its during the assignment that the expression on the right is evaluated where you lose the %20 I believe. I actually lose the &word when I try it as well since that is the Database character by default. Adding a ~ in front of the % and & worked for me:

thanks, I'll give it a shot...

hummm --- you were right, the & is causing a problem, but the ~ isn't fixing it...

You're doing a double assignment to webadr. Your first assignment puts the ~ in front of the & correctly. The second assignment with the %replace doesn't put the ~ back in front of the & (it was removed by the evaluation of the right side of the first assignment). If you do the double replace like I did in the example I posted before, that should fix the problem.

The reason it looks like it's skipping the word type is that the & makes zMUD think the following word is the name of a database variable. Since it's not, a null value ends up going in its place which makes it look like the word was skipped.

works the same with or without it.
tried it both ways.

Apprentice Joined: 29 Dec 2000 Posts: 146 Location: USA

even tried

Hrm, sorry. I forgot this was the zMUD thread and was testing it in CMUD where it works fine. I have the same problem with it that you're describing when doing it in zMUD and so far haven't figured out how to fix it.

I wish I could use cmud... it crashes so often it's unusable. started several threads, but no one has ever been able to help.

It just struck me, doubling up the & character might quote it. So try && instead.

Posted: Mon Jan 05, 2009 1:28 am

I just tried out that idea and it doesn't work either... you end up with this (note the missing 'type' after the &):

www.web.com/add.php?name=a%20golden%20sceptre&=LIGHT

If you're not using database variables you can go into preferences and turn off the database variable character on the special characters screen and it seems to work. You could also change the database character from & to something else I imagine... but that would involve changing any scripts you have that make use of the & database character plus you could mess others things up if you choose the new character badly...

I don't use any db stuff..the website I send the data to has a mysql back-end, and much better stuff :)
