Okay, in markupexprplus.php I changed line 176 to just give back the variable
$expr without doing the eval() stuff.
i.e. from
---
return $expr ? eval("return 0 + ($expr);") : '';
---
to
---
return $expr;
---
In my example:
---
:U:1
:K:0.5
{(add {$:U} {$:K})}:)
---
I now get
---
1)+(0,5
---
without producing an error. As I see it, pmwiki somehow changes the "." to a
",". That might have something to do with my (German) locale. Can I somehow
modify the eval() part to get the correct value(s)?
Any tip would be helpful. Thanks a lot.
