NAME

       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.

       o Tabulations should be avoided and replaced with eight spaces.

       o Indentation is generally 4 spaces.

       o Lines should wrap at most at 79 characters.

       o Do not leave whitespace at the end of lines.

       o Do not use multiple spaces for anything else than indentation.

       o 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;
	       }
	   }
       }

       Nothing here yet.
