Luadin Add-on

A wrapper for writing Vaadin applications in Lua

Luadin is a wrapper for the vaadin API that allows for writing Vaadin applications in Lua. Its purpose is to hide any complexities that are caused by Java interop and to present a simpler interface to the programmer

Luadin contains the Luaj interpreter with some fixes. No additional dependencies are required. The Luaj interpreter is released under the Luaj license.

The project is currently in a very early stage, so the API cannot be expected to be stable.

Sample code

 args = ...
    local luadin = require "luadin"
    function init(layout)
        local label = luadin.Label("Just a label")
        local vl = luadin.VerticalLayout()
        vl.addComponent(label)
        local b = luadin.Button("Click this")
        b.addClickListener(function() 
            local l = luadin.Label("Button clicked!")
            vl.addComponent(l)
        end)
        vl.addComponent(b)
        layout:addComponent(vl.getContainerInstance())
    end
    init(args)
