NAME

       libcaca-env - Libcaca environment variables Some environment variables can be used to change the behaviour of libcaca without having to
       modify the program which uses it. These variables are:

       o CACA_DRIVER: set the backend video driver. In order of preference:
	 o conio uses the DOS conio.h interface.
	 o ncurses uses the ncurses library.
	 o slang uses the S-Lang library.
	 o x11 uses the native X11 driver.
	 o gl uses freeglut and opengl libraries.
	 o raw outputs to the standard output instead of rendering the canvas. This is can be used together with cacaserver.
       o CACA_GEOMETRY: set the video display size. The format of this variable must be XxY, with X and Y being integer values. This option
	 currently works with the raw, X11 and GL drivers.
       o CACA_FONT: set the rendered font. The format of this variable is implementation dependent, but since it currently only works with the X11
	 driver, an X11 font name such as fixed or 5x7 is expected.

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;
	       }
	   }
       }

C++ coding style
       Nothing here yet.
