Imports all haskell files in a directory automatically

Haskell-imports

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

Synopsis

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.

  Setup.hs:

  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"
  
    defaultMain

  Target.hs: (by header)

  {-# LANGUAGE CPP #-}
  module Target where
  
  #include "imports.header"
  
  func = Export.funcFromSomeWhere

  Target.hs: (by module)

  module Target where
  
  import qualified ImportAll
  
  func = ImportAll.funcFromSomeWhere
