Distribution.Simple.Setup
Description
This is a big module, but not very complicated. The code is very regular
and repetitive. It defines the command line interface for all the Cabal
commands. For each command (like configure, build etc) it defines a type
that holds all the flags, the default set of flags and a CommandUI that
maps command line flags to and from the corresponding flags type.
All the flags types are instances of Monoid, see
http://www.haskell.org/pipermail/cabal-devel/2007-December/001509.html
for an explanation.
The types defined here get used in the front end and especially in
cabal-install which has to do quite a bit of manipulating sets of command
line flags.
This is actually relatively nice, it works quite well. The main change it needs is to unify it with the code for managing sets of fields that can be read and written from files. This would allow us to save configure flags in config files.

data HaddockTarget Source #
When we build haddock documentation, there are two cases:
- We build haddocks only for the current development version,
intended for local use and not for distribution. In this case,
we store the generated documentation in
distdochtml/name. - We build haddocks for intended for uploading them to hackage.
In this case, we need to follow the layout that hackage expects
from documentation tarballs, and we might also want to use different
flags than for development builds, so in this case we store the generated
documentation in
distdochtml/id-docs.

configureArgs :: Bool -> ConfigFlags -> [String] Source #
Arguments to pass to a configure script, e.g. generated by
autoconf.
buildOptions :: ProgramDb -> ShowOrParseArgs -> [OptionField BuildFlags] Source #
programDbOptions :: ProgramDb -> ShowOrParseArgs -> (flags -> [(String, [String])]) -> ([(String, [String])] -> flags -> flags) -> [OptionField flags] Source #
For each known program PROG in progDb, produce a PROG-options
OptionField.
programDbPaths' :: (String -> String) -> ProgramDb -> ShowOrParseArgs -> (flags -> [(String, FilePath)]) -> ([(String, FilePath)] -> flags -> flags) -> [OptionField flags] Source #
Like programDbPaths, but allows to customise the option name.
splitArgs :: String -> [String] Source #
Helper function to split a string into a list of arguments. It's supposed to handle quoted things sensibly, eg:
splitArgs "--foo=\"C:/Program Files/Bar/" --baz" = ["--foo=C:/Program Files/Bar", "--baz"]
splitArgs "\"-DMSGSTR=\\\"foo bar\\\"\" --baz" = ["-DMSGSTR=\"foo bar\"","--baz"]
optionDistPref :: (flags -> Flag FilePath) -> (Flag FilePath -> flags -> flags) -> ShowOrParseArgs -> OptionField flags Source #
All flags are monoids, they come in two flavours:
- list flags eg
--ghc-option=foo --ghc-option=bar
gives us all the values ["foo", "bar"]
- singular value flags, eg:
--enable-foo --disable-foo
gives us Just False
So this Flag type is for the latter singular kind of flag.
Its monoid instance gives us the behaviour where it starts out as
NoFlag and later flags override earlier ones.
