Problem with unbalanced parens in a stringlist item
|
Take the following code:
| Code: |
#VAR xtest1 {test1}
#VAR xtest2 {test2}
#VAR xtest2 {%push( @xtest1, @xtest2)}
#SHOW {items: %numitems( @xtest2) %item( @xtest2, 1)}
#VAR xtest1 {"test1 :-)"}
#VAR xtest2 {test2}
#VAR xtest2 {%push( @xtest1, @xtest2)}
#SHOW {items: %numitems( @xtest2) %item( @xtest2, 1)}
#VAR xtest2 {test2}
#VAR xtest2 {%push( %quote( @xtest1), @xtest2)}
#SHOW {items: %numitems( @xtest2) %item( @xtest2, 1)} |
When you run it, once you put an unbalanced paren into the stringlist, the stringlist variable xtest2 is no longer acting like a stringlist, even if you %quote() it:
| Code: |
items: 2 test1
items: 1 test1 :-)|test2
items: 1 test1 :-)|test2

Zhiroc... you are right. This is a parsing bug. What happens is that when zMud converts it to a stringlist you get something like
When it reparses when you try to access it a again it sees the unmatched ')' and wraps the entire thing in parens like so
When this is redisplayed of course the out put is completely different because what was a 2 item list, is treated as one entity.
You can see this more clear if you define a StringList variable, switch it to text and then back list variable.
On the upside, with all the parsing corrections Zugg has made, I'm sure this won't be an issue any more. |
