Build instructions

Mac OS X

make

Emscripten

emmake make emscripten

Note that mousewheel support requires a hacked emscripten:

In src/library_glfw.js, replace the first part of the mousewheel function with

      GLFW.wheelPos = (event.detail || -event.deltaY);

In system/include/GL/glfw.h, replace the wheel callback typedef with

typedef void (GLFWCALL * GLFWmousewheelfun)(float);

Style protobuf

We're encoding the styling information as a protocol buffer, according to proto/style.proto. The reason for doing so is that we don't have to ship with a JSON/yaml parser. To test the conversion script, run

bin/convert-style.js | protoc --decode=style proto/style.proto

You should see a nicely formatted hierarchical output of the converted style.
