nit. empty line before this one

[abarth-chromium, 2013/11/18 15:33:05]

Done.

+#include "gin/runner.h"

+namespace gin {
+
+class FileModuleProvider {
+ public:
+  explicit FileModuleProvider(const base::FilePath& base);
+  virtual ~FileModuleProvider();

[jochen (gone - plz use gerrit), 2013/11/18 12:46:05]

why is this virtual? Did you intend to have a ModuleProvider base class?

[abarth-chromium, 2013/11/18 15:33:05]

Yeah, I had one in an earlier iteration of the CL and forgot to remove the
virtual destructor.  We'll probably have one eventually to generalize better the
local and remote case, but I've removed the virtual destructor for now.

[jochen (gone - plz use gerrit), 2013/11/18 12:46:05]

should this have some kind of callback that is invoked if the module was loaded
successfully or not?

[abarth-chromium, 2013/11/18 15:33:06]

We could certainly add that, but it wouldn't be used currently.
