curHieVersion :: Word8

Current version of .hie files

data HieFile

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.

Value binding

Fields

• BindType

  whether or not the binding is in an instance

• Scope

  scope over which the value is bound

• (Maybe Span)

Pattern binding

This case is tricky because the bound identifier can be used in two distinct scopes. Consider the following example (with -XViewPatterns)

do (b, a, (a -> True)) <- bar
   foo a

The identifier a has two scopes: in the view pattern (a -> True) and in the rest of the do-block in foo a.

Fields

  scope in the pattern (the variable bound can be used further in the pattern)

• Scope

  rest of the scope outside the pattern

• (Maybe Span)

  span of entire binding

data TyVarScope

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] Nothing which later gets resolved into a ResolvedScopes.

Constructors

ResolvedScopes [Scope]

UnresolvedScope

Unresolved scopes should never show up in the final .hie file

Fields

• [Name]

  names of the definitions over which the scope spans

• (Maybe Span)

  the location of the instance/class declaration for the case where the type variable is declared in a method type signature
