One of these things that feels natural after 1 minute. I never want to go back to the rest of Internet now :-(

I really enjoy making coding notes in org mode because you can do stuff like this. Be nice to see it come to the web.

I typed -1 in factorial demo and script ended responding :)

  Fix it then run the code again ;)

  Thanks. I fixed it by returning 1 for negative numbers. With clojure snippets, Klipse protects itself from infinite loops - but not with lua snippets.

My browser doesn't (yet) support web assembly. Is there a reason you picked wasm_lua over (e.g.) lua.vm.js?
- viebel 10y ago
  I was not aware of lua.vm.js Thanks for the pointer

    See my comment from yesterday: https://news.ycombinator.com/item?id=13900372 https://news.ycombinator.com/item?id=13900372 as a quick comparison of the various lua-in-js implementations.

Interesting. It does work on Firefox 52 Edit: working on Chrome 57.0.2987.110 on Mac OSX (just check for the latest version) The funny thing is that <= gets converted to the actual symbol (less than or equal to) automatically when typing.

Also works on current Chrome (v57.0.2987.110) on Mac. Nice.

"--the evaluation will appear here (soon)..." Does this mean my browser doesn't support web assembly?
- viebel 10y ago
  Yes :(

    Then use ASM.js, at least it's JS and works with all browsers. Then it would work on mobile browsers too.

Works with Firefox on Android. Nice!

Amazing. klipse gets better and better.

The other place "live" coding snippets has taken off is in webgl, the other language your browser probably supports. The Book Of Shaders uses this to good effect: https://thebookofshaders.com https://thebookofshaders.com

Does not work on iPad and safari or Chrome.

This obviously doesn't work everywhere, but I just want to say it's really awesome that it's possible altogether. Great work!
