data CombType Source #

Data type for classifying combinations (i.e., a function/constructor applied to some arguments).

Constructors

FuncCall

a call to a function where all arguments are provided

ConsCall

a call with a constructor at the top, all arguments are provided

FuncPartCall Int

a partial call to a function (i.e., not all arguments are provided) where the parameter is the number of missing arguments

ConsPartCall Int

a partial call to a constructor along with number of missing arguments

data Literal Source #

Data type for representing literals.

A literal is either an integer, a float, or a character constant.

Note: The constructor definition of Intc differs from the original PAKCS definition. It uses Haskell type Integer instead of Int to provide an unlimited range of integer numbers. Furthermore, float values are represented with Haskell type Double instead of Float.

Instances
Eq Literal Source #

Methods

(/=) :: Literal -> Literal -> Bool #

data Fixity Source #

Fixity of an operator.

Constructors

InfixOp

non-associative infix operator

InfixlOp

left-associative infix operator

InfixrOp

right-associative infix operator

Instances
Eq Fixity Source #

Defined in Curry.FlatCurry.Type

Methods

data OpDecl Source #

Operator declarations.

An operator declaration fix p n in Curry corresponds to the FlatCurry term (Op n fix p).

Note: the constructor definition of Op differs from the original PAKCS definition using Haskell type Integer instead of Int for representing the precedence.

Constructors

Op QName Fixity Integer 
Instances
Eq OpDecl Source # 
Instance details

Defined in Curry.FlatCurry.Type

Methods

(==) :: OpDecl -> OpDecl -> Bool #

(/=) :: OpDecl -> OpDecl -> Bool #

Show OpDecl Source # 
Instance details

Defined in Curry.FlatCurry.Type

data TypeExpr Source #

Type expressions.

A type expression is either a type variable, a function type, or a type constructor application.

Note: the names of the predefined type constructors are Int, Float, Bool, Char, IO, Success, () (unit type), (,...,) (tuple types), [] (list type)

Constructors

TVar TVarIndex

type variable

FuncType TypeExpr TypeExpr

function type t1 -> t2

TCons QName [TypeExpr]

type constructor application

ForallType [TVarIndex] TypeExpr

forall type

data ConsDecl Source #

A constructor declaration consists of the name and arity of the constructor and a list of the argument types of the constructor.

Constructors

type TVarIndex = Int Source #

Type variables are represented by (TVar i) where i is a type variable index.

data TypeDecl Source #

Declaration of algebraic data type or type synonym.

A data type declaration of the form

data t x1...xn = ...| c t1....tkc |...

is represented by the FlatCurry term

Type t [i1,...,in] [...(Cons c kc [t1,...,tkc])...]

where each ij is the index of the type variable xj

Note: The type variable indices are unique inside each type declaration and are usually numbered from 0.

Thus, a data type declaration consists of the name of the data type, a list of type parameters and a list of constructor declarations.

data Visibility Source #

Visibility of various entities.

Constructors

Public

public (exported) entity

Private

private entity

type VarIndex = Int Source #

Representation of variables.

type QName = (String, String) Source #

Qualified names.

In FlatCurry all names are qualified to avoid name clashes. The first component is the module name and the second component the unqualified name as it occurs in the source program.
