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 Flag a Source

All flags are monoids, they come in two flavours:

  1. list flags eg
--ghc-option=foo --ghc-option=bar

gives us all the values ["foo", "bar"]

  1. 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.
