libcaca-style - Libcaca coding style

General guidelines

A pretty safe rule of thumb is: look at what has already been done and try to do the same.

• Tabulations should be avoided and replaced with eight spaces.
• Indentation is generally 4 spaces.
• Lines should wrap at most at 79 characters.
• Do not leave whitespace at the end of lines.
• Do not use multiple spaces for anything else than indentation.
• Code qui fait des warnings == code de porc == deux baffes dans ta gueule

C coding style

Try to use short names whenever possible (i for indices, w for width, cv for canvas...). Macros are always uppercase, variable and function names are always lowercase. Use the underscore to separate words within names:

#define BROKEN 0
#define MAX(x, y) ((x > y) ? (x) : (y))
unsigned int x, y, w, h;
char *font_name;
void frobulate_every_three_seconds(void);

const is a suffix. It's char const *foo, not const char *foo.

Use spaces after commas and between operators. Do not use spaces after an opening parenthesis or before a closing one:

a += 2;
b = (a * (c + d));
x = min(x1, x2, x3);

Do not put a space between functions and the corresponding opening parenthesis:

int function(int);

A space can be inserted after keywords such as for, while or if, but consistency with the rest of the page is encouraged:

if(a == b)


    return;
if (p == NULL)

Do not put parentheses around return values:

return a + (b & x) + d[10];

Opening braces should be on a line of their own, aligned with the current block. Braces are optional for one-liners:

int function(int a)
{


    if(a & 0x84)


        return a;


    if(a < 0)


    {


        return -a;


    }


    else


    {


        a /= 2;


        switch(a)


        {


            case 0:


            case 1:


                return -1;


                break;


            default:


                return a;


        }


    }
}
