Wire

Wire is a small reactive wrapping for LÖVE framework, highly inspired in Cycle.js (the web development framework) and it's fractal state management, onionify.

Wire allows you to take advantage of the awesomeness of LÖVE in a fully reactive and delightfull way. No global variables all around, no imperative actions, no mixed concerns (interaction, logic, side-effects, etc).

You just need to wire everything up declarativelly and let the data flow freely throughout your game.

Installation

luarocks install wire

Hello reactive world

local rx = require 'rx'
local wire = require 'wire'

local function game(sources)
  return {
    reducer = rx.Observable.merge(

      -- initial state
      rx.Observable.of(function()
        return {
          text = 'Hello World'
        })
      end),

      -- update state on key press
      sources.events.keypressed
        :filter(
          function(key)
            return key == 'space'
          end
        )
        :map(
          function()
            -- return a reducer function to update state
            return function(prevState)
              -- returned table will be merged to current
              -- state, updating value of text key
              return {
                text = 'Hello Interactive World :)'
              }
            end
          end
        )
    ),

    -- emit render function on state update
    render = sources.state:map(
      function(state)
        return function()
          love.graphics.print(state.text, 8, 8)
        end
      end
    )
  }
