/*
Example to get you started :
linux : gcc main.c -lX11 -lXrandr -lGL
windows : gcc main.c -lopengl32 -lgdi32
macos : gcc main.c -framework Cocoa -framework OpenGL -framework IOKit
#define RGFW_IMPLEMENTATION
#include "RGFW.h"
u8 icon[4 * 3 * 3] = {0xFF, 0x00, 0x00, 0xFF, 0xFF, 0x00, 0x00, 0xFF, 0xFF, 0x00, 0x00, 0xFF, 0xFF, 0x00, 0x00, 0x00, 0xFF, 0xFF, 0x00, 0xFF, 0xFF, 0xFF, 0x00, 0xFF, 0xFF, 0x00, 0x00, 0xFF, 0xFF, 0x00, 0x00, 0xFF, 0xFF, 0x00, 0x00, 0xFF};
int main() {
RGFW_window* win = RGFW_createWindow("name", RGFW_RECT(100, 100, 500, 500), (u64)0);
RGFW_window_setIcon(win, icon, RGFW_AREA(3, 3), 4);
for (;;) {
RGFW_window_checkEvent(win); // NOTE: checking events outside of a while loop may cause input lag
if (win->event.type == RGFW_quit || RGFW_isPressed(win, RGFW_escape))
break;
RGFW_window_swapBuffers(win);
glClearColor(1, 1, 1, 1);
glClear(GL_COLOR_BUFFER_BIT);
}
RGFW_window_close(win);
}
compiling :
if you wish to compile the library all you have to do is create a new file with this in it
rgfw.c
#define RGFW_IMPLEMENTATION
#include "RGFW.h"
You may also want to add
`#define RGFW_EXPORT` when compiling and
`#define RGFW_IMPORT`when linking RGFW on it's own:
this reduces inline functions and prevents bloat in the object file
then you can use gcc (or whatever compile you wish to use) to compile the library into object file
ex. gcc -c RGFW.c -fPIC
after you compile the library into an object file, you can also turn the object file into an static or shared library
(commands ar and gcc can be replaced with whatever equivalent your system uses)
static : ar rcs RGFW.a RGFW.o
shared :
windows:
gcc -shared RGFW.o -lopengl32 -lgdi32 -o RGFW.dll
linux:
gcc -shared RGFW.o -lX11 -lGL -lXrandr -o RGFW.so
macos:
gcc -shared RGFW.o -framework Cocoa -framework OpenGL -framework IOKit

Credits :
EimaMei/Sacode : Much of the code for creating windows using winapi, Wrote the Silicon library, helped with MacOS Support, siliapp.h -> referencing
stb - This project is heavily inspired by the stb single header files
GLFW:
certain parts of winapi and X11 are very poorly documented,
GLFW's source code was referenced and used throughout the project.
contributors : (feel free to put yourself here if you contribute)
krisvers -> code review
EimaMei (SaCode) -> code review
