Description

Definitions of various semantic objects (*not* the Futhark semantics themselves).

Synopsis

Documentation

data ImportName Source #

Canonical reference to a Futhark code file. Does not include the .fut extension. This is most often a path relative to the current working directory of the compiler.

mkInitialImport :: FilePath -> ImportName Source #

Create an import name immediately from a file path specified by the user.

mkImportFrom :: ImportName -> String -> SrcLoc -> ImportName Source #

We resolve '..' paths here and assume that no shenanigans are going on with symbolic links. If there is, too bad. Don't do that.

includeToFilePath :: ImportName -> FilePath Source #

Create a .fut file corresponding to an ImportName.

includeToString :: ImportName -> String Source #

Produce a human-readable canonicalized string from an ImportName.

data FileModule Source #

The result of type checking some file. Can be passed to further invocations of the type checker.

Constructors

FileModule 

Fields

type Imports = [(String, FileModule)] Source #

A mapping from import names to imports. The ordering is significant.

Modules produces environment with this representation.

type TySet = Map (QualName VName) Liftedness Source #

data BoundV Source #

Type parameters, list of parameter types (optinally named), and return type. The type parameters are in scope in both parameter types and the return type. Non-functional values have only a return type.
