optparse-applicative can't really support "--arg name value", so instead we require "--arg name=value", printing an error message if the user attempts the former. |

hnix
Haskell parser, evaluator and type checker for the Nix language.
Prerequisites
Nix is installed and in your $PATH. This is so that nix-store can be used
for interacting with store paths, until hnix-store is ready.
Getting Started
$ git clone https://github.com/jwiegley/hnix.git
...
$ cd hnix
$ cabal2nix --shell . > default.nix
$ nix-shell
...
$ cabal test
...
$ cabal bench
...
$ ./dist/build/hnix/hnix --help
Building with profiling enabled
To build hnix with profiling enabled:
$ nix-shell --arg doProfiling true
$ cabal configure --enable-tests --enable-profiling
$ ./dist/build/hnix/hnix <args> +RTS -p
How you can help
If you're looking for a way to help out, try taking a look here. When you find an issue that looks interesting to you, comment on the ticket to let others know you're working on it; look for others who might have done the same. You can talk with everyone live on gitter.
When you're ready to submit a pull request, test it with:
git submodule update --init --recursive
nix-shell --run "LANGUAGE_TESTS=yes cabal test"
Make sure that all the tests that were passing prior to your PR are still passing afterwards; it's OK if no new tests are passing.
