binop[A, R](c: Context)(rhs: scala.reflect.macros.whitebox.Context.Expr[A]): scala.reflect.macros.whitebox.Context.Expr[R]
Given context and an expression, this method rewrites the tree to call the "desired" method with the lhs and rhs parameters.
Given context and an expression, this method rewrites the tree to call the "desired" method with the lhs and rhs parameters. We find the symbol which is applying the macro and use its name to determine what method to call.
If we see code like:
lhs + rhs
After typing and implicit resolution, we get trees like:
conversion(lhs)(ev).$plus(rhs: A): R
The macro should produce trees like:
ev.method(lhs: A, rhs: A): R

Like binop, but with ev provided to the method instead of to the implicit constructor.

Combine an implicit enrichment with a lifting method.
Combine an implicit enrichment with a lifting method.
If we see code like:
lhs + 1
After typing and implicit resolution, we get trees like:
conversion(lhs)(ev0).$plus(1)(ev1): R
The macro should produce trees like:
ev0.plus(lhs, ev1.fromInt(1))
In Spire, this lets us use
Ring
's fromInt method andConvertableTo
'sfromDouble
(etc.) before applying an op. Eventually, we should generalize the way we choose the lifting method.- Definition Classes

This is like binopWithLift, but we use the same evidence parameter to make the method call and do the lifting.

Provide a canonical mapping between "operator names" used in

Ops
classes and the actual method names used for type classes.It's worth noting that a particular instance of
Ops
must always map a given symbol a single method name. If you want to be able to map the same symbol to different names in different contexts, you'll need to create multipleOps
instances and configure them appropriately.In general "textual" method names should just pass through to the typeclass--it is probably not wise to provide mappings for them here.
