style system variables

[kaigou]

Is it possible to set a variable to be another variable?

That is, instead of:

set color_thing = "#333366";

doing:

set color_thing = $*some_other_thing;

such that the default value of $*color_thing is equal to the value of $*some_other_thing, but with option for user to override?

Right inside your print_stylesheet function, you should be able to require that variable x equal variable y. But that would screw with the ability of the user to select something totally different if that's what floats their boat. So I guess either you want to frame your x=y statement in such a way that if the values are changed they decouple, or else just set both variables to the same thing up in the settables list. *rueful* I usually go with the latter, despite it being longhand, as it were.

Hmm. Unless it's something like:

if $x = "" { $x = $y } else { $x = $z }

...or something like that. I'm thinking back to the "leave blank for default" discussion elsewhere (per the wizard), and that if the user left the entry blank, then the default would prevail. In which case, the input -- $x -- would be = "" instead of = "user-input".
