How can I create a notation for atomic objects? (Assume I have reasons
to not use the Notation package.) Creating a notation for subscripted
objects is easy:
Format[Effort[n__]] := Subscript[\[ScriptE],n];
MakeExpression[SubscriptBox["\[ScriptE]", nd_], StandardForm] :=
MakeExpression[RowBox[{"Effort", "[", nd, "]"}],
StandardForm];
Allows me to use Effort[n] and subscripted \[ScriptE] interchangably.
This also ensures that the FullForm of the subscripted \[ScriptE] is
Effort[] (which is necessary for pattern matching elsewhere in my
package.)
But what if I want to have the same relationship between a symbol Time
and \[DoubleStruckT] ? The subscripted notation above comes wrapped in
a SubscriptBox, but the atomic notation of \[DoubleStruckT] is not
wrapped in any kind of box (that I can tell). Also, if I do get it to
work with single symbols, what happens when that symbol appears within
a RowBox, as in the expression
\[DoubleStruckT] + 1
?
