* Generalize OverridingPairs to SymbolPairs.Paul Phillips2013-10-051-3/+3
| | | | | | | | | | | | | | | | | Increases your chance of knowing what is going on in OverridingPairs. Introduces some new abstractions which I hope for your own sakes you will put to use in some way: RelativeTo: operations relative to a prefix SymbolPair: two symbols being compared for something, and the enclosing class where the comparison is being performed Fixed a minor bug with access by accident by way of more principled pair analysis. See run/private-override.scala. Upgraded the error message issued on certain conflicts to give the line numbers of both conflicting methods, as opposed to just one and you go hunting.
* Selective dealiasing when printing errors.Paul Phillips2011-10-031-1/+1

It cannot serve both these roles simultaneously, primarily because of package objects but other little things as well. Since in the majority of situations we want the one which corresponds to the idealized scala world, not the grubby bytecode, I went with that for fullName. When you require the path to a class (e.g. you are calling Class.forName) you should use javaClassName. package foo { package object bar { class Bippy } } If sym is Bippy's symbol, then sym.fullName == foo.bar.Bippy sym.javaClassName == foo.bar.package.Bippy *** End important note *** There are many situations where we (until now) forewent revealing everything we knew about a type mismatch. For instance, this isn't very helpful of scalac (at least in those more common cases where you didn't define type X on the previous repl line.) scala> type X = Int defined type alias X scala> def f(x: X): Byte = x <console>:8: error: type mismatch; found : X required: Byte def f(x: X): Byte = x ^ Now it says: found : X (which expands to) Int required: Byte def f(x: X): Byte = x ^ In addition I rearchitected a number of methods involving: - finding a symbol's owner - calculating a symbol's name - determining whether to print a prefix No review.
