## C Coding Style Conventions
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 fullscreen = 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");`
Other conventions:
- All defined variables are ALWAYS initialized
- Four spaces are used, instead of TABS
- Trailing spaces are always avoided
- Control flow statements are followed **by a space** :
```c
if (condition) value = 0;
while (!WindowShouldClose())
{
}
for (int i = 0; i < NUM_VALUES ; i + + ) printf ( " % i " , i ) ;
switch (value)
{
case 0:
{
} break;
case 2: break;
default: break;
}
```
- All conditions are always between parenthesis, but not boolean values:
```c
if ((value > 1) & & (value < 50 ) & & valueActive )
{
}
```
- Braces and curly brackets always open-close in aligned mode:
```c
void SomeFunction()
{
// TODO: Do something here!
}
```
## Files and Directories Naming Conventions
- Directories are named using `snake_case` : `resources/models` , `resources/fonts`
- Files are named using `snake_case` : `main_title.png` , `cubicmap.png` , `sound.wav`
_NOTE: Spaces and special characters are always avoided in the files/dir naming!_
## Games/Examples Directories Organization Conventions
- Resource files are organized by context and usage in the game. Loading requirements for data are also considered (grouping data when required).
- Descriptive names are used for the files, just reading the name of the file it should be possible to know what is that file and where fits in the game.

_NOTE: Some resources require to be loaded all at once while other require to be loaded only at initialization (gui, font)._
