Amulet is no longer under development. If you're interested in other languages which compile to Lua, do check out this list.
Amulet
Amulet is a simple functional programming language in the ML tradition, with support for higher-rank parametric polymorphic types and row-polymorphic records, pattern matching with algebraic data types, and tail recursion elimination.
Installation
For your convenience, we provide pre-built tarballs for x86_64 Linux
that are compiled every night from the master branch (as part of the
nightly build job, linked above). Install them with the magic install
script:
curl https://amulet.works/install.sh | env CHANNEL=nightly sh -
Building from Source
Make sure you have a functional Haskell toolchain including Stack. Since
Amulet has a lot of object files (around 125 for the amc executable,
not counting all of the Haskell dependencies that are shipped as .a
static libraries), we use the LLVM lld linker in the Cabal file.
If you do not wish to use lld, remove all the ghc-options: stanzas
from the amuletml.cabal file; This sed command should do the trick,
too.
sed -re 's;-optl-fuse-ld=lld;;g' -i amuletml.cabal
Amulet ships with its own set of libraries. Make sure they are
installed. amc will look for its libraries in one of the following
directories:
${AMC_LIBRARY_PATH}
$(dirname $(which amc))/lib
$(dirname $(which amc))/../lib
The script tools/quickinstall.sh will take care of building and
installing the libraries, using Stack.
