imports: Generate code for importing directories automatically

[ development, library, mit ] [ Propose Tags ]

This module helps to automatically generate code for importing all the haskell files from directories.


For cabal inited project, we customize Setup.hs file to generate the importing code.

  • Be sure to modify the build-type field in the .cabal file from Simple to Custom.

  • Then modify the main function in Setup.hs to generate importing code by either header file or a module file.


import Distribution.Simple
import System.Imports (writeImportsHeader, writeImportsModule)

main = do
  writeImportsHeader "imports.header" "Export" "Some.Where" "Some/Where"
  -- or
  writeImportsModule "ImportAll.hs" "ImportAll" "Some.Where" "Some/Where"


Target.hs: (by header)

module Target where

#include "imports.header"

func = Export.funcFromSomeWhere

Target.hs: (by module)

module Target where

import qualified ImportAll

func = ImportAll.funcFromSomeWhere
