ufo

I first got introduced to the concept by his talk, and this implementation here - http://sol.gfxile.net/imgui/ch01.html (latest archive I could find - https://web.archive.org/web/20200428143845/http://sol.gfxile...) I've did some translations of the above C/C++ code to lua longtime here (actually luajit, as it requires the FFI) - https://github.com/malkia/ufo/blob/master/samples/SDL/imgui/... (simplest example) through https://github.com/malkia/ufo/blob/master/samples/SDL/imgui/... though my hack for C/C++'s __LINE__ macro was local function GEN_ID() return CURRENT_LINE() end e.g. you basically tie the state to the... ahem.. source code line (you need really something unique). Obviously Dear ImGUI has better approaches there (use the widget's contents, like text/label contents, or add your own with ##).

Ironically, your username is one of the neatest Lua[JIT] projects I've seen. https://github.com/malkia/ufo

That bouncing ball, is from GLBoing.c (can be found in glfw), like here: https://github.com/g-truc/ogl-samples/blob/master/external/g... or luajit version: https://github.com/malkia/ufo/blob/master/samples/glfw/boing... git clone https://github.com/malkia/ufo cd ufo luajit samples/glfw/boing.lua (should work on Windows, may still work on Linux/OSX)

I've collected few rounded square (squircles :)) codes using cairo (through luajit): http://cairographics.org/cookbook/roundedrectangles/ http://graphics.stanford.edu/courses/cs248-98-fall/Final/q1.... and two more here (but I forgot to put the links where I got the code from, and I don't recall being my original code): https://github.com/malkia/ufo/blob/master/samples/cairo/ui.l... gfx:round_rect_a() gfx:round_rect_b() gfx:round_rect_c() gfx:round_rect_d()

Almost straight port here to luajit - http://github.com/malkia/ufo/blob/master/samples/notch.lua

I have this excellent tutorial translated to luajit+sdl ffi bindings http://github.com/malkia/ufo/tree/master/samples/SDL/imgui

I've started bindings for certain LuaJIT FFI libs, and have put some small samples - but pretty much unorganized. http://github.com/malkia/ufo Just try this one, it shows some raw speed of luajit: ./luajit samples/intro.lua Should work on Windows, OSX, Linux (x86 and arm (EfikaMX)) As long as things are kept in lua much of the time, and rarely call "C" for the better. And if "C" is to be called, it better be called through the FFI - pure awesomeness...

I've made LuaJIT FFI bindings to some "C" precompiled libraries for these platforms: OSX, iOS, Windows, Linux (x86+arm) There libraries are: GLFW, SDL, ZeroMQ, AntTweakBar, and planning on few more. There is also OpenCL and OpenGL and glu. Please visit: http://github.com/malkia/ufo You should not need to recompile, as I've packaged the binaries.

I'm back to lua (actually luajit) after not using it for few years, and this time using C only through luajit's FFI. So far onlly one issue (not a small one) - no callbacks from C -> lua - so you have to be careful what libraries you would choose. And connecting "C" and "LuaJIT" through FFI - that's quite easy. I've started a little project with such bindings http://github.com/malkia/ufo - OpenGL, OpenCL, AntTweakBar (OpenGL "property" dialog), ZeroMQ, GLFW (GLUT like library that can be used without callbacks), and few others.
