Quaff

=====

Quaff is a set of tools for integrating Elixir into erlang applications (or vice versa).

Quaff.Constants

---------------

This module parses erlang header files, and imports any constants as `@` attributes. A constant means a `-define` macro which evaluates to a constant term, and takes no arguments (though it may use macros which accept arguments).  Constants whose names start with a capital letter will have an underscore prepended, for compatibility with Elixir syntax.

app/include/app_header.hrl:

    -define(CONSTANT_FROM_APP,5)

lib/mymodule.ex:

    defmodule MyModule

       require Quaff.Constants

       Quaff.Constants.include_lib("app/include/app_header.hrl")

       def myfunc() do

         @_CONSTANT_FROM_APP + 10

       end

    end

Quaff.Debug

-----------

The Debug module provides a simple helper interface for running Elixir code in the erlang graphical debugger, using the technique I described in [this posting](http://qhool.github.io/elixir/2014/02/06/elixir-debug.html).

    Interactive Elixir (0.12.2) - press Ctrl+C to exit (type h() ENTER for help)

    iex(1)>  Quaff.Debug.start() #start the graphical debugger

    {:ok, #PID<0.59.0>}

    iex(2)>  Quaff.Debug.load("./lib/mymodule.ex") #load all modules in source file

    lib/mymodule.ex:1: redefining module My.Module

    lib/mymodule.ex:212: redefining module My.OtherModule

    [module: My.Module, module: My.OtherModule]

    iex(3)>  Quaff.Debug.load(Yet.AnotherModule) #load a module by name

    {:module, Yet.AnotherModule}

Also provided is `nload(module)` (equivalent to `load(module, all_nodes: true)`), which debugs the module[s] on all known nodes.
