Change what's allowed in extern mod directives #6407
Description
Sub-bug of #5677
Currently, extern mod directives take an identifier, like: extern mod foo;. We need to instead allow two different forms of extern mod:
First, extern mod foo = "github.com/catamorphism/an-awesome-package-called-foo";
Second, extern mod "github.com/catamorphism/a_valid_identifier";
In the first case, you specify that foo is the short name for the package at the URL (or URL-fragment) on the right-hand side of the =. This allows remote paths to contain any Unicode characters while also associating the package with a valid Rust identifier.
In the second case, rustpkg guesses that a_valid_identifier is the short name. Omitting the foo = in the first case would be a usage error, since the stem of the URL fragment is not a valid identifier (it contains hyphens).

rustc/rusti/rustpkg: Infer packages from `extern mod` directives
catamorphism commentedon May 29, 2013
For now we're going to say
extern mod foo (id = "github.com/catamorphism/an-awesome-package-called-foo");, since that syntax is already supported. Leaving this bug open but not blocking on it.rustc/rusti/rustpkg: Infer packages from `extern mod` directives

@catamorphism can this be removed from 0.7 if the syntax isn't an issue?
catamorphism commentedon Jun 25, 2013
@cmr Right, forgot about that. Cleared milestone.

Note: 'foo' is not the short name of the package you compile; it's just the local in-crate binding.
