I'll be doing some SVG graphics work and applied some Lumikki-kind
thinking to making a simple SVG generation tool, in Lua.
Currently available only by svn checkout, from:
svn co svn://slugak.dyndns.org/public/2009/Svg
Here's one of the sample files:
--
-- ELLIPSE1.LUA
--
require "svgcore"
local rgb= assert(svg.rgb)
print( svg.document(
svg.default{ stroke_dasharray={2,2},
--
svg.ellipse{ {80,110}, {75,105}, fill="#538" },
svg.ellipse{ {80,110}, {60,40}, fill="black", stroke="red",
stroke_width=25 },
svg.ellipse{ {80,110}, {35,20}, fill="#538",
stroke="yellow", stroke_width=25 },
svg.ellipse{ {80,50}, {40,30}, fill="red", stroke="black",
stroke_width=25 },
svg.ellipse{ {80,50}, {30,20}, fill="orange", stroke="red",
stroke_width=10 },
svg.ellipse{ {80,170}, {40,30}, fill="yellow",
stroke="orange", stroke_width=25 },
svg.ellipse{ {80,170}, {30,20}, fill="red", stroke="black",
stroke_width=10 }
}
) )
The idea is that Lua syntax is a bit nicer to craft than XML, but
this also allows programmatic creation of macro-like objects
(functions that create graphical objects) that can be turned
around, copied etc.. SVG has a "uses" element for that, but this is
more easy on the eyes (clearer code).
I post this mostly to inform if anyone has a similar need. Be my
guest and use it. Haven't decided the license yet.
Btw, SVG + JavaScript is a perfect blend for making visually good-
looking UI applications. SVG in theory support any scripting
language, so maybe we can at one day have SVG+Lua viewer.
