C Coding Style Conventions

Here it is a list with some of the code conventions used by raylib:

Code element	Convention	Example
Defines	ALL_CAPS	#define PLATFORM_DESKTOP
Macros	ALL_CAPS	#define MIN(a,b) (((a)<(b))?(a):(b))
Variables	lowerCase	int screenWidth = 0;, float targetFrameTime = 0.016f;
Local variables	lowerCase	Vector2 playerPosition = { 0 };
Global variables	lowerCase	bool windowReady = false;
Constants	lowerCase	const int maxValue = 8;
Pointers	MyType *pointer	Texture2D *array = NULL;
float values	always x.xf	float gravity = 10.0f
Operators	value1*value2	int product = value*6;
Operators	value1/value2	int division = value/4;
Operators	value1 + value2	int sum = value + 10;
Operators	value1 - value2	int res = value - 5;
Enum	TitleCase	enum TextureFormat
Enum members	ALL_CAPS	PIXELFORMAT_UNCOMPRESSED_R8G8B8
Struct	TitleCase	struct Texture2D, struct Material
Struct members	lowerCase	texture.width, color.r
Functions	TitleCase	InitWindow(), LoadImageFromMemory()
Functions params	lowerCase	width, height
Ternary Operator	(condition)? result1 : result2	printf("Value is 0: %s", (value == 0)? "yes" : "no");

Some other conventions to follow:

• ALWAYS initialize all defined variables.
• Do not use TABS, use 4 spaces instead.
• Avoid trailing spaces, please, avoid them
• Control flow statements always are followed by a space:

if (condition) value = 0;

while (!WindowShouldClose())
{

}

for (int i = 0; i < NUM_VALUES; i++) printf("%i", i);

// Be careful with the switch formatting!
switch (value)
{
    case 0:
    {

    } break;
    case 2: break;
    default: break;
}

• All conditions checks are always between parenthesis but not boolean values:

if ((value > 1) && (value < 50) && valueActive)
{

}

• When dealing with braces or curly brackets, open-close them in aligned mode:

void SomeFunction()
{
   // TODO: Do something here!
}

If proposing new functions, please try to use a clear naming for function-name and functions-parameters, in case of doubt, open an issue for discussion.

Files and Directories Naming Conventions

• Directories will be named using snake_case: resources/models, resources/fonts

• Files will be named using snake_case: main_title.png, cubicmap.png, sound.wav

NOTE: Avoid any space or special character in the files/dir naming!

Games/Examples Directories Organization Conventions

• Data files should be organized by context and usage in the game, think about the loading requirements for data and put all the resources that need to be loaded at the same time together.
• Use descriptive names for the files, it would be perfect if just reading the name of the file, it was possible to know what is that file and where fits in the game.
• Here it is an example, note that some resources require to be loaded all at once while other require to be loaded only at initialization (gui, font).
