[3.19d-] BUG?: @var.key expansion
|
In the case of the following code, should @food.cheese return the string value "%int(@calories * 0.33)" or the integer value '333'? In 3.17, I had always expected the results to be an integer value; Though recent testing makes me wonder if that was a bug.
| Code: |
<?xml version="1.0" encoding="ISO-8859-1" ?>
<cmud>
<class name="Test" copy="yes">
<var name="calories" copy="yes">1000</var>
<alias name="test" copy="yes">
<value>#print @food.cherry_pie
#print @food.cheese</value>
</alias>
<var name="food" type="Record" copy="yes">
<value>cheese=%int(@calories * 0.33)|dessert=1|cherry_pie=%int(@calories*3/4)|utensil=fork|entrees=one,two</value>
<json>{"dessert":1,"cherry_pie":"%int(@calories*3\/4)","utensil":"fork","entrees":"one,two","cheese":"%int(@calories * 0.33)"}</json>
</var>
</class>
</cmud> |

It should return a String value, not a number. Variable expansion in CMUD (unlike zMUD) is not recursive. So the function should not getting evaluated unless you use %eval on the result.
My guess is that the code which handles user-defined functions was messed up with the previous string list and database variables and might have been treating a string value as a user-defined function, which isn't allowed within a string list or database variable.
However, your report *does* indicate a problem/bug with the import of json XML. When I import your above variable, the underlying json table isn't correct, so I've added that to the bug list. |
