GHC.SourceGen.Module

This module provides combinators for constructing Haskell modules, including import and export statements.

HsModule'

type HsModule' = HsModule GhcPs

module'

Arguments

:: Maybe ModuleNameStr

-> Maybe [IE']

Exports

-> [ImportDecl']

-> [HsDecl']

-> HsModule'

Import declarations

type ImportDecl' = ImportDecl GhcPs

qualified' :: ImportDecl' -> ImportDecl'

as' :: ImportDecl' -> ModuleNameStr -> ImportDecl'

import' :: ModuleNameStr -> ImportDecl'

exposing :: ImportDecl' -> [IE'] -> ImportDecl'

hiding :: ImportDecl' -> [IE'] -> ImportDecl'

source :: ImportDecl' -> ImportDecl'

Adds the {--} pragma to an import.

Imported/exported things

type IE' = IE GhcPs

An imported or exported entity, as it is represented after the parsing step.

Instances:

• BVar
• Var

thingAll :: RdrNameStr -> IE'

Exports all methods and/or constructors.

A(..)
=====
thingAll "A"

thingWith :: RdrNameStr -> [OccNameStr] -> IE'

Exports specific methods and/or constructors.

A(b, C)
=====
thingWith "A" ["b", "C"]

moduleContents :: ModuleNameStr -> IE'

Exports an entire module.

Note: this is not valid inside of an import list.

module M
=====
moduleContents "M"
