Luna is a developer’s whiteboard on steroids. Design, prototype, develop and refactor any application simply by connecting visual elements together. Collaborate with co-workers, interactively fine tune parameters, inspect the results and visually profile the performance in real-time.

These instructions give the most direct path to a working Luna development environment.

Linux (Ubuntu 14.04-LTS, 15.10), MacOS (...) and Windows (...) are officialy supported host development operating systems.

For MacOS, you need the latest Xcode and the following dependencies:

brew install git python3 pkg-config ghc cabal-install

For Ubuntu, you'll need the following development dependencies:

sudo apt-get install git python3 haskell-platform

Via HTTPS For those checking out sources as read-only, HTTPS works best:

git clone https://github.com/wdanilo/luna.git
git clone https://github.com/wdanilo/workflow.git

Via SSH For those who plan on regularly making direct commits, cloning over SSH may provide a better experience (which requires uploading SSH keys to GitHub):

git clone git@github.com:wdanilo/luna.git
git clone git@github.com:wdanilo/workflow.git

The workflow/build script is a high-level build wrapper for every project from Luna's ecosystem. To learn about the supported options, use the help one:

workflow/build --help

Note: Arguments after -- above are passed directly to Haskell's build system Stack.

To fast start the development use the following command:

workflow/build luna/compiler

If you want to use the newest available libraries that Luna depends on, you can use the newest available versions on GitHub instead of Hackage. It is usefull if you are developing the libraries as well and don't want to wait until Hackage propagates information about new library versions:

workflow/build --nightly luna/compiler

You can also setup fully-flagged local development workspace and use local directories to override the sources of needed libraries. You will need a libs directory next to workflow and luna and use the --develop option:

workflow/build --develop luna/compiler

If you want to release a final Luna compiler version, you can enable the highest possible optimizations and disable some tricks used for compilation fastening using the --release flag instead.
