Description

Explanation: Simple build system; basically the interface for Distribution.Simple.* modules. When given the parsed command-line args and package information, is able to perform basic commands like configure, build, install, register, etc.

This module isn't called "Simple" because it's simple. Far from it. It's called "Simple" because it does complicated things to simple software.

Simple interface
defaultMain :: IO ()
A simple implementation of main for a Cabal setup script. It reads the package description file using IO, and performs the action specified on the command line.
defaultMainNoRead :: PackageDescription -> IO ()
Like defaultMain, but accepts the package description as input rather than using IO to read it.
Customization
data UserHooks
Hooks allow authors to add specific functionality before and after a command is run, and also to specify additional preprocessors.
Constructors
UserHooks
runTests :: (Args -> Bool -> LocalBuildInfo -> IO ExitCode)Used for ./setup test
readDesc :: (IO (Maybe PackageDescription))Read the description file
hookedPreProcessors :: [PPSuffixHandler]Custom preprocessors in addition to and overriding knownSuffixHandlers.
preConf :: (Args -> ConfigFlags -> IO HookedBuildInfo)
postConf :: (Args -> ConfigFlags -> LocalBuildInfo -> IO ExitCode)
preBuild :: (Args -> Int -> IO HookedBuildInfo)
postBuild :: (Args -> Int -> LocalBuildInfo -> IO ExitCode)

postCopy :: (Args -> CopyFlags -> LocalBuildInfo -> IO ExitCode)
preInst :: (Args -> InstallFlags -> IO HookedBuildInfo)
postInst :: (Args -> InstallFlags -> LocalBuildInfo -> IO ExitCode)guaranteed to be run on target

type Args = [String]
defaultMainWithHooks :: UserHooks -> IO ()
A customizable version of defaultMain.
defaultUserHooks :: UserHooks

Basic default UserHooks:

  • on non-Windows systems, postConf runs ./configure, if present.
  • all pre-hooks except preConf read additional build information from package.buildinfo, if present.

Thus configure can use local system information to generate package.buildinfo and possibly other files.

emptyUserHooks :: UserHooks
Empty UserHooks which do nothing.
defaultHookedPackageDesc :: IO (Maybe FilePath)
Optional auxiliary package information file (pkgname.buildinfo)
