This knob allows pulling in a revised .cabal file for a Haskell package being ported. This allows us to drop local patches that were serving the same purpose.

# Provide support for building Haskell packages using Cabal.
|
|
#
|
|
# Feature: cabal
|
|
# Usage: USES=cabal or USES=cabal:ARGS
|
|
# Valid ARGS: hpack, nodefault
|
|
#
|
|
# hpack: The port doesn't have a .cabal file and needs devel/hs-hpack to
|
|
# generate it from package.yaml file
|
|
# nodefault: Do not fetch the default distribution file from Hackage. If
|
|
# USE_GITHUB or USE_GITLAB is specified in the port, this argument
|
|
# is implied.
|
|
#
|
|
# Variables, which can be set by the port:
|
|
#
|
|
# USE_CABAL List of Haskell packages required to build a port.
|
|
# Should be listed along with version, like profunctors-5.3
|
|
# Package revision can be specified too with
|
|
# usual "_" syntax: invariant-0.5.1_1
|
|
# When creating a new port, the initial list can be built
|
|
# using make-use-cabal auxiliary target.
|
|
#
|
|
# CABAL_REVISION Specifies a Haskell package revision. Set this to an
|
|
# integer to pull in revised .cabal file from Hackage.
|
|
#
|
|
# CABAL_FLAGS List of Cabal flags to be passed verbatim into --flags
|
|
# argument of cabal-install utility. Used for both
|
|
# cabal configure and cabal build.
|
|
#
|
|
# CABAL_EXECUTABLES List of executable Cabal targets to be built and installed.
|
|
# Consult the .cabal file of the project being ported to find
|
|
# out possible values for this variable.
|
|
# default: ${PORTNAME}
|
|
#
|
|
# opt_USE_CABAL Variant of USE_CABAL to be used with options framework.
|
|
# opt_CABAL_FLAGS Variant of CABAL_FLAGS to be used with options framework.
|
|
# Note that it works a bit differently from CABAL_FLAGS:
|
|
# it appends "${opt_CABAL_FLAGS}" when the option is enabled
|
|
# and "-${opt_CABAL_FLAGS}" otherwise.
|
|
# opt_CABAL_EXECUTABLES Variant of CABAL_EXECUTABLES to be used with
|
|
# options framework.
|
|
#
|
|
# CABAL_WRAPPER_SCRIPTS A subset of ${CABAL_EXECUTABLES} containing Haskell
|
|
# programs to be wrapped into a shell script that sets
|
|
# *_datadir environment variables before running the program.
|
|
# This is needed for Haskell programs that install their
|
|
# data files under share/ directory.
|
|
#
|
|
# FOO_DATADIR_VARS Additional environment vars to add to FOO executable's
|
|
# wrapper script.
|
|
#
|
|
# CABAL_PROJECT Sets how to treat existing cabal.project file. Possible
|
|
# values are "remove" and "append".
|
|
#
|
|
# SKIP_CABAL_PLIST Set to "yes" to prevent Haskell executables from being
|
|
# added to the pkg-plist automatically.
