bitlash

[GoogleCodeExporter]

Add binding to http://bitlash.net/
probably needs something like
u8g line 1 2 3 4
ug8 text x y "text"
--> not sure if bitslash supports strings for user defined functions

Bitlash user defined functions are able to accept string constant arguments.  
In your user function, cast the result of getarg(n) to char* and off you go.  
So ug8_text(22,33,"foo") would work just fine for text placement.

Hi Bill
Thanks for clarification!

If you like, it is pretty easy to get printf-formatted output using the 
built-in bitlash printf() formatter via the func_printf_handler hook, something 
like this:

//////////
//
//  Send one byte of generated output to the text display system
//  Used in func_xyprintf() below.
//
void display_put_char(byte) {
    // call your function to display one byte of generated output
    // do bookkeeping for the position of the next char here too
    ...
}

//////////
//
// xyprintf(): print formatted output at [x,y]
//
//  Examples: 
//      xyprintf(0, 0, "Hello, world!");
//      xyprintf(22, 5, "Time: %5d", millis);
//
numvar func_xyprintf(void) {

    // call your function to save the text rendering position
    // set_xy(getarg(0), getarg(1));
    ...

    // generate formatted output
    setOutputHandler(&display_put_char);    // redirect output to handler above
    func_printf_handler(3,4);       // format=arg(3), optional args start at 4
    resetOutputHandler();           // restore normal serial output
    return 0;
}
