type Span = RealSrcSpan Source #
hieVersion :: Integer Source #
Current version of .hie files
GHC builds up a wealth of information about Haskell source as it compiles it.
.hie files are a way of persisting some of this information to disk so that
external tools that need to work with haskell source don't need to parse,
typecheck, and rename all over again. These files contain:
a simplified AST
- nodes are annotated with source positions and types
- identifiers are annotated with scope information
- the raw bytes of the initial Haskell source
Besides saving compilation cycles, .hie files also offer a more stable
interface than the GHC API.

data TyVarScope Source #
Scope of a type variable.
This warrants a data type apart from Scope because of complexities
introduced by features like -XScopedTypeVariables and -XInstanceSigs. For
example, consider:
foo, bar, baz :: forall a. a -> a
Here a is in scope in all the definitions of foo, bar, and baz, so we
need a list of scopes to keep track of this. Furthermore, this list cannot be
computed until we resolve the binding sites of foo, bar, and baz.
Consequently, a starts with an UnresolvedScope [foo, bar, baz] NothingResolvedScopes.
