GHC.Iface.Load

Load interface directly for a fully qualified Module. (This is a fairly rare operation, but in particular it is used to load orphan modules in order to pull their instances into the global package table and to handle some operations in GHCi).

Load interfaces for a collection of modules.

Load the interface corresponding to an import directive in source code. On a failure, fail in the monad with an error message.

Like loadSrcInterface, but returns a MaybeErr.

Loads the interface for a given Name. Should only be called for an imported name; otherwise loadSysInterface may not find the interface

Loads the interface for a given Module.

Loads a system interface and throws an exception if it fails

Loads a user interface and throws an exception if it fails. The first parameter indicates whether we should import the boot variant of the module

readIface tries just the one file.

Failed err = file not found, or unreadable, or illegible Succeeded iface = successfully found and parsed

Write interface file

Compute the signatures which must be compiled in order to load the interface for a Module. The output of this function is always a subset of moduleFreeHoles; it is more precise because in signature p[A=<A>,B=<B>]:B, although the free holes are A and B, B might not depend on A at all!

If this is invoked on a signature, this does NOT include the signature itself; e.g. precise free module holes of p[A=<A>,B=<B>]:B never includes B.

An IfM function to load the home interface for a wired-in thing, so that we're sure that we see its instance declarations and rules See Note [Loading instances for wired-in things]

Reason for loading an interface file

Used to figure out whether we want to consider loading hi-boot files or not.

Show a ModIface but don't display details; suitable for ModIfaces stored in the EPT.

The UnitState is used to pretty-print units

Read binary interface, and print it out
