The dat2c utility




======================================
============ Introduction ============
======================================


The utility dat2c can be used in much the same way as dat2s, above, except
that it writes C code rather than assembler. This has the advantage that it
is portable - you can compile it anywhere you can use Allegro.



=============================================
============ Commandline Options ============
=============================================


Each option may appear only once. To specify which datafile to convert,
give the filename without a preceding option.

--cfile, -o
    Arguments: filename
    
    Gives the name of the C source file to output. Won't add a .c 
    extension, even if you don't specify one. By default, dat2c will
    write to stdout.
    
--hfile, -h
    Arguments: filename
    
    Gives the name of the C header file to output. Won't add a .h
    extension, even if you don't specify one.
    
--prefix, -p
    Arguments: prefix (must be a valid macro name)
    
    If you specify a prefix, then this will be used when constructing a
    macro name for each object in the datafile. This is the same as the
    grabber; if you don't specify a prefix, the macro name is simply
    <obj_name>, but if you do, then the macro name becomes
    <prefix>_<obj_name> .

--crlf, -C
    Arguments: none
    
    Forces the file to be output in CRLF (DOS) format. This is the
    default on DOS/Windows platforms.
    
--unix, -U
    Arguments: none
    
    Sets the output to be in Unix (LF only) text format. This is the
    default on non-DOS non-Mac platforms.
    
--mac, -M
    Arguments: none
    
    Sets the output to be in Macintosh (CR only) text format. This is
    the default on Mac platforms.

--global, -g
    Arguments: none
    
    Specifies that the objects should be globally visible (default is
    for objects to be local to the compilation unit). If they are
    globally visible, then you can refer to them in your code.

--convert-compiled-sprites, -S
    Arguments: none
    
    (See note below for more info on compiled sprites). Tells dat2c to
    convert any compiled sprite objects it finds into bitmap objects.
    More a convenience feature for lazy people :-)

--datafile-name, -n
    Arguments: C identifier
    
    By default, the datafile is exported as:
        PREFIX_data
    or  data
    But with this option, you can change 'data' to be something else.



===============================
============ Notes ============
===============================

 - If your datafile contains truecolor images, be sure to call 
   fixup_datafile() after you have set the graphics mode. You must
   also call fixup_datafile() if your platform does not support
   constructors (currently any non GCC-based platform).
   
 - Compiled sprites are *not* supported (but see the commandline option
   --convert-compiled-sprites , above). This is because Allegro silently
   switches to an RLE_SPRITE implementation on platforms which don't 
   support compiled sprites, and to get dat2c to implement that behaviour
   would be more effort than it is worth (especially since you can just
   call get_compiled_sprite() anyway!).
