Macros and Functions
c2hs_toolchain
Declare a Haskell c2hs toolchain.
You need at least one of these declared somewhere in your BUILD
files for the chs_library
rule to work. Once declared, you then
need to register the toolchain using register_toolchains
in
your WORKSPACE
file (see example below).
Examples
In a BUILD
file:
c2hs_toolchain(
name = "c2hs",
c2hs = "@c2hs//:bin",
)
where @c2hs
is an external repository defined in the
WORKSPACE
, e.g. using:
nixpkgs_package(
name = "c2hs",
attribute_path = "haskell.packages.ghc822.c2hs",
)
register_toolchains("//:c2hs")
