Network Support

Scrupp SVN contains version 2.0.2 of the Lua network library LuaSocket written by Diego Nehab.

The website of LuaSocket contains an introduction and a reference.

The doc directory of the Scrupp distribution contains a local snapshot of the LuaSocket documentation.

Everything described in this documentation works exactly the same way in Scrupp.

Example

-- size of the window
local width, height = 600, 400

scrupp.init("LuaSocket Test", width, height, 32, false)

-- loads the HTTP module and any libraries it requires
local http = require("socket.http")

-- download a screenshot from the scrupp website
local img = http.request("http://scrupp.sourceforge.net/screenshots/linux_default_thumb.png")

-- convert the string to a scrupp image
img = scrupp.addImageFromString(img)

-- get the size of the image
local w, h = img:getSize()

-- calculate the coordinates of the image (for center position)
local x, y = (width-w)/2, (height-h)/2

main = {
	render = function(dt)
		-- render the screenshot at the center of the window
		img:render(x,y)	
	end,
	
	keypressed = function(key)
		if key == "ESCAPE" then
			scrupp.exit()
		end
	end
}
