Summary: I would like to define a variable only if certain conditions,
determined at run-time, are true. But this doesn't seem possible. Have I
missed something?
Detail:
I'm setting up the data for an array, ultimately for a "key=value" formatted
file, going via the recommended standard library and its "edit_line
set_variable_values(v)". The intuitive way would be:
============
class:
"runtime_condition" and => { ...foo ; bar ... };
vars:
v string => "always1";
v string => "always2";
v string => "sometimes1"
ifvarclass => "runtime_condition";
============
That "ifvarclass" would be very nice, very intuitive and very clean. But it
doesn't work.
Calls where the run-time condition is true would get a three-element array
corresponding to "index1", "index2" and "conditional1" and the file would get
three "key=value" lines controlled by this. Calls where it is false would get
the two-element array corresponding just to "index1" and "index2" and the file
would get just two "key=value" lines controlled by this.
For my current problem: have I missed something?
For the developers: if this isn't currently possible in the intuitive way
given above, could this enhancement be made in future versions?
