/** \page tutorial A libcucul and libcaca tutorial
Super short example:
Before writing your first libcaca application, you need to know the difference between libcucul and libcaca :
- libcucul is the text rendering library. It will do all the work you actually need. From imports (text, ANSI, caca internal format, all of this supporting n-bytes unicode), to exports (sames formats, adding SVG, PostScript, TGA, HTML (both 3 and 4), IRC), it'll cover all your needs.
- libcaca handle everything that can be hardware related. It includes display (RAW, X11, OpenGL, Windows (GDI), conio (DOS), ncurses, slang, text VGA (IMB-Compatible)), keyboard (same drivers but RAW), mouse (same drivers but RAW and VGA), time and resize events (on windowed drivers).
So, you can write a libcucul only program, but you <b>can't</b> write a libcaca only program, it'll be nonsense. Period.
First, a working program, very simple, to check you can compile and run it :
What does it do ? (we skip variable definitions, guessing you have a brain) :
- Create a cucul canvas. A canvas is where everything happens. Writing characters, sprites, strings, images, everything. It is mandatory and is the reason for libcuculs' beeing. Size is there a width of 0 pixels, and a height of 0 pixels. It'll be resized according to contents you put in it.
- Create a caca display. This is basically the window. Physically it can be a window (most of the displays), a console (ncurses, slang) or a real display (VGA).
- Set the window name of our display (only available in windowed displays, does nothing otherwise). (so this is libcaca related)
- Set current colors to black background, and white foreground of our canvas (so this is libcucul related)
- Put a string "This is a message" with current colors in our libcucul canvas.
- Refresh our caca display, whish was firstly attached to our canvas
- Wait for an event of type "CACA_EVENT_KEY_PRESS", which seems obvious.
- Free display (release memory)
- Free canvas (release memory and close window if any)
