Nirum is an [IDL][1] compiler and [RPC][2]/[distributed object][3] framework
for [microservices][4], built on top of the modern Web server technologies
such as RESTful HTTP and JSON.

You can find how its IDL looks like from source codes in the `examples/`
directory.

**Note that its design is highly unstable and could be changed.**
Also the feature set is incomplete yet.

Nightly builds
--------------

The easiest way to give a try to use Nirum is downloading a nightly build.
We currently provides the prebuilt binaries of the following platforms:

- [Linux (x86_64)](https://nightly-builds.nirum.org/travis-builds/nirum-linux-x86_64)
- [Mac (x86_64)](https://nightly-builds.nirum.org/travis-builds/nirum-darwin-x86_64)
- [Windows (x64)](https://ci.appveyor.com/api/projects/dahlia/nirum-k5n5y/artifacts/nirum-win-x64.exe?job=Platform%3A%20x64&branch=master)
- [Windows (x86)](https://ci.appveyor.com/api/projects/dahlia/nirum-k5n5y/artifacts/nirum-win-x86.exe?job=Platform%3A%20x86&branch=master)
- [Docker (`spoqa/nirum:latest`)][docker]


Getting started
---------------

In order to compile a Nirum package (`examples/`) to a Python package:

    $ mkdir out/  # directory to place generated Python files
    $ nirum -o out/ examples/

For more infomration, use `--help` option:

    $ nirum --help
    Nirum Compiler 0.1.0

    nirum [OPTIONS] DIR

    Common flags:
      -o --output-dir=DIR   The directory to place object files
      -? --help             Display help message
      -V --version          Print version information
         --numeric-version  Print just the version number


Building
--------

If you already installed [Haskell Platform][5] or [Haskell Stack][6],
you can build the project in the same way to build other Haskell projects.

Using Stack:

    $ stack build

Using vanilla Cabal:

    $ cabal sandbox init
    $ cabal install --only-dependencies
    $ cabal configure
    $ cabal build
