# @BLURB: for packages that make use of the Haskell Common Architecture for Building Applications and Libraries (cabal) |
23 |
# @DESCRIPTION: |
24 |
# Basic instructions: |
25 |
# |
26 |
# Before inheriting the eclass, set CABAL_FEATURES to |
27 |
# reflect the tools and features that the package makes |
28 |
# use of. |
29 |
# |
30 |
# Currently supported features: |
31 |
# haddock -- for documentation generation |
32 |
# hscolour -- generation of colourised sources |
33 |
# hoogle -- generation of documentation search index |
34 |
# profile -- if package supports to build profiling-enabled libraries |
35 |
# bootstrap -- only used for the cabal package itself |
36 |
# lib -- the package installs libraries |
37 |
# nocabaldep -- don't add dependency on cabal. |
38 |
# only used for packages that _must_ not pull the dependency |
39 |
# on cabal, but still use this eclass (e.g. haskell-updater). |
40 |
# ghcdeps -- constraint dependency on package to ghc onces |
41 |
# only used for packages that use libghc internally and _must_ |
42 |
# not pull upper versions |
43 |
# test-suite -- add support for cabal test-suites (introduced in Cabal-1.8) |
44 |
# rebuild-after-doc-workaround -- enable doctest test failue workaround. |
45 |
# Symptom: when `./setup haddock` is run in a `build-type: Custom` |
46 |
# package it might cause cause the test-suite to fail with |
47 |
# errors like: |
48 |
# > <command line>: cannot satisfy -package-id singletons-2.7-3Z7pnljD8tU1NrslJodXmr |
49 |
# Workaround re-reginsters the package to avoid the failure |
50 |
# (and rebuilds changes). |
51 |
# FEATURE can be removed once https://github.com/haskell/cabal/issues/7213 |
52 |
# is fixed. |
