# @DESCRIPTION: |

1.1 |
# Basic instructions: |
| 14 |
|
|
# |
| 15 |
|
|
# Before inheriting the eclass, set CABAL_FEATURES to |
| 16 |
|
|
# reflect the tools and features that the package makes |
| 17 |
|
|
# use of. |
| 18 |
|
|
# |
| 19 |
|
|
# Currently supported features: |
| 20 |
|
|
# haddock -- for documentation generation |
| 21 |
kolmodin |
1.21 |
# hscolour -- generation of colourised sources |
| 22 |
slyfox |
1.35 |
# hoogle -- generation of documentation search index |
| 23 |
kosmikus |
1.1 |
# alex -- lexer/scanner generator |
| 24 |
|
|
# happy -- parser generator |
| 25 |
|
|
# c2hs -- C interface generator |
| 26 |
|
|
# cpphs -- C preprocessor clone written in Haskell |
| 27 |
|
|
# profile -- if package supports to build profiling-enabled libraries |
| 28 |
|
|
# bootstrap -- only used for the cabal package itself |
| 29 |
dcoutts |
1.3 |
# bin -- the package installs binaries |
| 30 |
|
|
# lib -- the package installs libraries |
| 31 |
kolmodin |
1.16 |
# nocabaldep -- don't add dependency on cabal. |
| 32 |
slyfox |
1.23 |
# only used for packages that _must_ not pull the dependency |
| 33 |
|
|
# on cabal, but still use this eclass (e.g. haskell-updater). |
| 34 |
slyfox |
1.32 |
# test-suite -- add support for cabal test-suites (introduced in Cabal-1.8) |
