Re: [Bug-gnubg] Web version of GNU Backgammon

[Theodore Hwa]

Thanks for the pointer to Broadway, I'll have to look into it. For the 
initial project, I didn't look into running GTK in the browser, since I 
figured that would be the easiest part to do in Javascript directly.

It is currently done in pure JS without any special libraries.  An HTML5 
canvas is used to draw the board, checkers, dice, etc. directly 
(fortunately backgammon needs only simple geometric shapes that can be 
drawn easily, unlike (say) chess). I set gnubg to output the FIBS 
rawboard, which the JS intercepts and then updates the board.  You can see 
the source code in the github project link in the original message.  The 
board drawing logic is in the graphics.js file.
