Description

This module contains data types used by the compiler.

Synopsis

Data types

data CompOpts Source #

A type to store options passed to compile. Eventually all of this might be able to be integrated into a Compile monad.

Constructors

CompileOptions 

Fields

  • coptsThisFunc :: String

    Immediate name to use when creating a compiled function. Presumably there is other code that is expecting to call into it.

  • coptsThisFuncUseValue :: Bool

    Whether to include the value parameter in the current function

  • coptsThisFuncUseArgs :: Bool

    Whether to include the args parameter in the current function

  • coptsNextFunc :: Maybe String

    The name to use for the next function after the current compiler recursion is finished. For example, after compiling a block of code, the control flow would be expected to go to this function.

data CompLibOpts Source #

Options passed to the compiler library module

Constructors

CompileLibraryOptions 

Fields

defaultCompileOptions :: String -> CompOpts Source #

The default compiler options

data HaskAST Source #

A very basic type to store a Haskell AST.

Constructors

AstAssignM String HaskAST 
AstFunction 

Fields

AstValue String 
AstRef String 
AstContinuation 

Fields
