Hello list!
Is there any possibility to convert a FD var to a string in order to
display it e.g. in a GUI? Say I have a list of values (containing
integers and constraint variables) and want to show their values in a
GUI, e.g.
[1 1#9 5 2#3 4]
I alos tried to check the type of the variable, but Int.is does not seem
to work on fd vars.
Use Value.toVirtualString, then convert the virtual string into a string
or an atom. See:
declare X in
X :: [1#10 20#30]
{Show {VirtualString.toAtom {Value.toVirtualString X 0 0}}}
Cheers,
raph
