Language.Futhark.Syntax

The Futhark source language AST definition. Many types, such as ExpBase, are parametrised by type and name representation. E.g. in a value of type ExpBase f vn, annotations are wrapped in the functor f, and all names are of type vn. See https://futhark.readthedocs.org for a language reference, or this module may be a little hard to understand.

The system of primitive types is interesting in itself. See Language.Futhark.Primitive.

module Language.Futhark.Core

prettyString :: Pretty a => a -> String

Prettyprint a value to a String, appropriately wrapped.

prettyText :: Pretty a => a -> Text

Types

data Uniqueness

The uniqueness attribute of a type. This essentially indicates whether or not in-place modifications are acceptable. With respect to ordering, Unique is greater than Nonunique.

Constructors

Nonunique

May have references outside current function.

Unique

No references outside current function.

data Size

The elaborated size of a dimension.

NamedSize (QualName VName)

The size of the dimension is this name, which must be in scope. In a return type, this will give rise to an assertion.

ConstSize Int

The size is a constant.

AnySize (Maybe VName)

No known size. If Nothing, then this is a name distinct from any other. The type checker should _never_ produce these - they are a (hopefully temporary) thing introduced by defunctorisation and monomorphisation.

data AppExpBase f vn

An "application expression" is a semantic (not syntactic) grouping of expressions that have "funcall-like" semantics, mostly meaning that they can return existential sizes. In our type theory, these are all thought to be bound to names (*Administrative Normal Form*), but as this is not practical in a real language, we instead use an annotation (AppRes) that stores the information we need, so we can pretend that an application expression was really bound to a name.

Constructors

Apply (ExpBase f vn) (ExpBase f vn) (f (Diet, Maybe VName)) SrcLoc

The Maybe VName is a possible existential size that is instantiated by this argument. May have duplicates across the program, but they will all produce the same value (the expressions will be identical).

data ExpBase f vn

The Futhark expression language.

This allows us to encode whether or not the expression has been type-checked in the Haskell type of the expression. Specifically, the parser will produce expressions of type Exp NoInfo Name, and the type checker will convert these to Exp Info VName, in which type information is always present and all names are unique.

ValBind

Fields

• valBindEntryPoint :: Maybe (f EntryPoint)

  Just if this function is an entry point. If so, it also contains the externally visible interface. Note that this may not strictly be well-typed after some desugaring operations, as it may refer to abstract types that are no longer in scope.

• valBindName :: vn
• valBindRetDecl :: Maybe (TypeExp vn)
• valBindRetType :: f StructRetType

  If valBindParams is null, then the retDims are brought into scope at this point.

data EntryPoint

Information about the external interface exposed by an entry point. The important thing is that that we remember the original source-language types, without desugaring them at all. The annoying thing is that we do not require type annotations on entry points, so the types can be either ascribed or inferred.
