-- This defines a 'PreProcessor' abstraction which represents a pre-processor
-- that can transform one kind of file into another. There is also a
-- 'PPSuffixHandler' which is a combination of a file extension and a function
-- for configuring a 'PreProcessor'. It defines a bunch of known built-in
-- preprocessors like @cpp@, @cpphs@, @c2hs@, @hsc2hs@, @happy@, @alex@ etc and
-- lists them in 'knownSuffixHandlers'. On top of this it provides a function
-- for actually preprocessing some sources given a bunch of known suffix
-- handlers. This module is not as good as it could be, it could really do with
-- a rewrite to address some of the problems we have with pre-processors.

-- |The interface to a preprocessor, which may be implemented using an
-- external program, but need not be.  The arguments are the name of
-- the input file, the name of the output file and a verbosity level.
-- Here is a simple example that merely prepends a comment to the given
-- source file:
--
-- > ppTestHandler :: PreProcessor
-- > ppTestHandler =
-- >   PreProcessor {
-- >     platformIndependent = True,
-- >     runPreProcessor = mkSimplePreProcessor $ \inFile outFile verbosity ->
-- >       do info verbosity (inFile++" has been preprocessed to "++outFile)
-- >          stuff <- readFile inFile
-- >          writeFile outFile ("-- preprocessed as a test\n\n" ++ stuff)
-- >          return ExitSuccess
--
-- We split the input and output file names into a base directory and the
-- rest of the file name. The input base dir is the path in the list of search
-- dirs that this file was found in. The output base dir is the build dir where
-- all the generated source files are put.
--
-- The reason for splitting it up this way is that some pre-processors don't
-- simply generate one output .hs file from one input file but have
-- dependencies on other generated files (notably c2hs, where building one
-- .hs file may require reading other .chi files, and then compiling the .hs
-- file may require reading a generated .h file). In these cases the generated
-- files need to embed relative path names to each other (eg the generated .hs
-- file mentions the .h file in the FFI imports). This path must be relative to
-- the base directory where the generated files are located, it cannot be
-- relative to the top level of the build tree because the compilers do not
-- look for .h files relative to there, ie we do not use \"-I .\", instead we
-- use \"-I dist\/build\" (or whatever dist dir has been set by the user)
--
-- Most pre-processors do not care of course, so mkSimplePreProcessor and
-- runSimplePreProcessor functions handle the simple case.
--
data PreProcessor = PreProcessor {

  -- Is the output of the pre-processor platform independent? eg happy output
  -- is portable haskell but c2hs's output is platform dependent.
  -- This matters since only platform independent generated code can be
  -- included into a source tarball.
  PreProcessor -> Bool
platformIndependent :: Bool,

  -- TODO: deal with pre-processors that have implementation dependent output
  --       eg alex and happy have --ghc flags. However we can't really include
  --       ghc-specific code into supposedly portable source tarballs.
