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.

Cool project. You have used emscripten to port the C code to webassembly? Isn't
there a port og GTK done with emscripten?
Another way to port to web would be to display the application itself with a
different GTK backend. I've tried that with the
Broadway backend that can display GTK applications directly in the browser.
I've tried it with GNU Backgammon, however I
think it fails for GNU Backgammon due to the OpenGL stuff.
How did you make the user interface? Is it pure js or do you use any fancy like
React or Angular or Vue?
(I guess JavaScript is the next thin on my *must learn* list)
Thanks!

A wonderful initiative. Perhaps one day we will have a reasonable Android

Hi gnubg users,
I have ported GNU Backgammon to the web, replacing the GTK UI with a
Javascript UI. You can see it hosted here:
http://xenon.stanford.edu/~hwatheod/gnubg_web/gnubg_web.html
As of now, you have to enter moves manually, like "8/5 6/5". You can enter
arbitrary gnubg command line commands, so nearly all the features of the
original are available.
The project repository is here:
https://github.com/hwatheod/gnubg-web
Some technical details: This was done by compiling gnubg's C source code
into Javascript/Webassembly with Emscripten. A browser supporting
Webassembly is required (the latest versions of most modern browsers do).
Any comments, suggestions, contributions are appreciated!
