Language.Futhark.Syntax

This is an ever-changing syntax representation for Futhark. Some types, such as Exp, are parametrised by type and name representation. See the https://futhark.readthedocs.org for a language reference, or this module may be a little hard to understand.

module Language.Futhark.Core

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 ExpBase f vn

The Futhark expression language.

In a value of type Exp f vn, annotations are wrapped in the functor f, and all names are of type vn.

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.
