# @BLURB: for packages that make use of the Haskell Common Architecture for Building Applications and Libraries (cabal)
|
|
# @DESCRIPTION:
|
|
# Basic instructions:
|
|
#
|
|
# Before inheriting the eclass, set CABAL_FEATURES to
|
|
# reflect the tools and features that the package makes
|
|
# use of.
|
|
#
|
|
# Currently supported features:
|
|
# haddock -- for documentation generation
|
|
# hscolour -- generation of colourised sources
|
|
# hoogle -- generation of documentation search index
|
|
# alex -- lexer/scanner generator
|
|
# happy -- parser generator
|
|
# c2hs -- C interface generator
|
|
# cpphs -- C preprocessor clone written in Haskell
|
|
# profile -- if package supports to build profiling-enabled libraries
|
|
# bootstrap -- only used for the cabal package itself
|
|
# bin -- the package installs binaries
|
|
# lib -- the package installs libraries
|
|
# nocabaldep -- don't add dependency on cabal.
|
|
# only used for packages that _must_ not pull the dependency
|
|
# on cabal, but still use this eclass (e.g. haskell-updater).
|
|
# ghcdeps -- constraint dependency on package to ghc onces
|
|
# only used for packages that use libghc internally and _must_
|
|
# not pull upper versions
|
|
# test-suite -- add support for cabal test-suites (introduced in Cabal-1.8)
|
|
|
