SDL_tty

=======

SDL_tty is a simple library that tries to simulate a primitive

terminal that allows you to print to the screen in much the same way

that you would print to stdout. The usage is like this:

    // Create the fixed width font

    SDL_Surface* temp = IMG_Load("fontfile.png");

    TTY_Font* font = TTY_CreateFont(temp, 16, 16,

                                    "\x7f !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ"

                                    "[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~");

    // Create the terminal

    TTY* tty = TTY_Create(40, 30, font);

    // Your mainloop

    while(1)

    {

       // print text via

       TTY_printf(tty, "Hello World\n");

       // renderer the terminal to the screen

       TTY_Blit(tty, screen, 80, 60);

       SDL_Flip(screen);

    }

    TTY_Free(tty);

    TTY_FreeFont(font);

`fontdump`

----------

The `fontdump` utility can be used to generate header files that can

be included straight into the source code so that there are no

external dependencies:

	Usage: fontdump FONTNAME IMAGEFILE GLYPHWIDTH GLYPHHEIGHT GLYPHS

Example:

    fontdump font8x8 font8x8.png 8 8 \

      "\x7f !\\"#$$%&\'()*+,-./0123456789:;<=>?@\

      ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_\`abcdefghijklmnopqrstuvwxyz{|}~" \

      > font8x8.h

`c64lookalike`

--------------

The `c64lookalike` programm demonstrates some more advanced usage of

the library.

Features

--------

* can create a primitive terminal for text output

* some primitve support for scrolling

* support for fixed-width fonts

* support for loading fonts from file as well as directly from code, a

  image to .h converter is provided

* small and meant to be included in your source, not meant to be compiled as

  a real .so/dll library
