Proposal:
1. Define a standard resolver module
module Resolve where
type Resolver = Args -> ModuleName -> IO HaskellSource resolve::Resolver
2. Require that Haskell compilers allow users to supply resolvers e.g.
ghci -r ../../Resolve.hs
That requires compile-time code generation and execution (i.e. template haskell), so I can't see all compilers implementing it. Instead, let me point you at the place in GHC to insert your resolver. In the module Finder, we have: findModule :: HscEnv -> Module -> Bool -> IO FindResult data FindResult = Found ModLocation PackageIdH -- the module was found | PackageHidden PackageId -- for an explicit source import: the package containing the module is -- not exposed. | ModuleHidden PackageId -- for an explicit source import: the package containing the module is -- exposed, but the module itself is hidden. | NotFound [FilePath] -- the module was not found, the specified places were searched. You can almost replace findModule with your own resolver. However, the question is what do you do for modules like "Prelude": it sounds like you'll need to have pre-compiled code for all the standard libraries around (I assume you want to avoid using packages).
