Notes on header files

Notes on header files

After over 20 years working with C/C++ I finally got clear idea how header files need to be organized. Most of the projects in C++ world simply dump everything in .h file, and most of my C++ code was organized this way. Lately I started to separate function declaration from implementation as it was done in C. Now .h headers are exclusevely intended for function and class declaration with doxygen documentation style comments. Inline implementation of functions, class method implementation, etc. goes into .inl headers or .cpp files.

For example .h file would contain only declaration and doxygen style documentation comment:

	/// Convert size in bytes to human readable string.
	void prettify(char* _out, int32_t _max, uint64_t _value)

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

Going from Lua 5.2 to PICO-8's Lua

This information applies to the PICO-8 0.1.6 release.

This document is here to help folks with a proficiency in Lua understand the limitations and discrepencies between Lua and PICO-8's Lua.

You can always view the manual or yellowafterlife's extended 0.1.1 manual.

General

  • anything written in uppercase the PICO-8 editor or .p8 is made lowercase by the editor. → editing the .p8 file directly can work
  • print(function() end) outputs the string function instead of the string function: 0x0000000.

GLSL Noise Algorithms

Please consider using http://lygia.xyz instead of copy/pasting this functions. It expand suport for voronoi, voronoise, fbm, noise, worley, noise, derivatives and much more, through simple file dependencies. Take a look to https://github.com/patriciogonzalezvivo/lygia/tree/main/generative

Generic 1,2,3 Noise

float rand(float n){return fract(sin(n) * 43758.5453123);}

float noise(float p){
	float fl = floor(p);
  float fc = fract(p);

OpenGL function loader for LuaJIT. This is a fixed up version of slime73's original code. See demo.lua for usage.
local glfw = require("glfw3") --Let's say we have a magic GLFW3 binding there!
local openGL = require("opengl")
openGL.loader = glfw.GetProcAddress
openGL:import()
--and somewhere else
local vbo = ffi.new("GLuint[1]")
gl.GenBuffers(1, vbo)
gl.BindBuffer(GL.ARRAY_BUFFER, vbo[0])
gl.BufferData(GL.ARRAY_BUFFER, ffi.sizeof(vertices), vertices, GL.STATIC_DRAW)
