Conway's Game of Life in Go, cross-platform
Uses Gio by @EliasNaur.

For the desktop app, Go 1.12 is fine.

To build the web version (which you don't have to do if you only want to run it), you'll need 1.13 / go tip. (Explaining "go tip" is beyond the scope of this readme, sorry.)

Again: the www/ directory in the repo is ready to run, no need to (re)build it. So if you just want to try it, you don't need "go tip".

% export GO111MODULE=on
% go run life.go

% go get github.com/shurcooL/goexec
% goexec 'http.ListenAndServe(":8080", http.FileServer(http.Dir("www")))'

Browse to http://localhost:8080.

Browse to http://theclapp.github.io/go-life/www/.
May take a few moments to download on your first visit; ~4 mb download (~1 mb on the wire).

(May not work in Chrome (see #1) though it does for me. If not, try a different browser.)

These work in the desktop app and in the browser.

• q to quit (in the browser this just halts execution)
• r to restart the universe with random cells
• - (minus key) to reduce the scale (zoom out)
• + to increase the scale (zoom in) (= also works)
• < or , to slow down the generations
• > or . to speed them up
• p pause
• c continue

You can also click-and-drag or scroll around.

You can't enter or save patterns yet.
