ghcjs-examples's Issues

"goog is not defined" error

Steps to reproduce:

cd ./ghcjs-examples/weblog/race
ghcjs -o race race.js
cp race.html ./race.jsexe
cd race.jsexe
open race.html

The example works fine (as expected), however my firefox's console shows ReferenceError: goog is not defined error for this line in lib.js: https://i.imgur.com/AslTLFK.png

webkit-sodium build fail

Trying to test ghcjs-hello package, when installing webkit-sodium:

Note: installing in sandbox.

src/Language/Javascript/JSaddle/Value.hs:116:29:
    Overlapping instances for Eq JSObjectRef
      arising from the first field of ‘ValObject’ (type ‘JSObjectRef’)
    Matching instances:
      instance Eq (JSRef a) -- Defined in ‘ghcjs-prim-0.1.0.0:GHCJS.Prim’
      instance Eq (JSRef Language.Javascript.JSaddle.Types.ValueOrObject)
        -- Defined at src/Language/Javascript/JSaddle/Types.hs:50:10
    When deriving the instance for (Eq JSValue)
Failed to install jsaddle-0.2.0.5
cabal: Error: some packages failed to install:
jsaddle-0.2.0.5 failed during the building phase. The exception was:

webkit-sodium-0.0.1 depends on jsaddle-0.2.0.5 which failed to install.

Environment:
GHCJS 0.1.0 (GHC 7.8.3)

System: 4.0.6-200.fc21.x86_64

Is this repo abandoned?

Guys, is it?

At the moment it does not build on travis.

As a newbie I cannot fix it myself, and indeed it was (for a newbie) an interesting challenge to get it working "somehow" - but it took half a day.

So the question is - could someone please fix travis builds so that it was a reproducible way to build all the demos?

Thanks.

Does ghcjs-hello have to be so complicated?

I was hoping for a simple Hello World that runs inside Webkit when natively compiled, or compiles to a simple JS application. But it seems to rely on stuff like Sodium even.

Heap visualization example?

In the New York talk about ghcjs Luite shows an example if a program showing the heap as it executes (or at least, I think it does -- the slides are very hard to see). Is that available anywhere? I'd love to play with that, would be awesome for writing explanatory Haskell blog posts!

Promise example

A lot (if not all) APIs these days are promise-based. Is there a nice way to interface with these? An example would be great.
