[1.33] Temp variable error possible bug
|
I have an alias that has the following script:
| Code: |
#if (@item.minlevel = {}) {#say bluhey} {$templev = %concat( {@item.minlevel},L);#say $templev;#say crapper}
#say $templev |
the @item.minlevel has the value of 12
If I run this alias as is, I get
| Code: |
ERROR: Syntax error in Alias: asdff : invalid local variable: templev
|
but if I comment out or delete the last #say $templev it shows the output from the #say $templev in the else part of the if statement. This looks to me like a bug. Why would it work within the if statement but not outside the if statement..... Temp variables arn't supposed to expire after going through an if statement are they? |

It's not a bug, it's to do with the scope of the local variable. You defined it within the #if statement, so it's removed when it ends. By the time the #say command runs, the variable's out of scope. If you want the variable to stay in scope for the whole alias, you need to define the variable with #local from outside the #if statement.
Also, your %concat syntax seems a bit weird. Unless you literally mean for the value of @item.minlevel to be displayed surrounded by {}, you don't need them, and you might need to quote the L to ensure it's parsed properly as a string. |
