ghcjs / ghcjs-examples Goto Github PK

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.

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.

The darcs get portion of the build fails.

http://patch-tag.com says this when I visit it in my browser:

Warning! Domain mapping upgrade for this domain not found. Please log in and go to the Domains Upgrades page of your blog to use this domain.

Is there another place I can get gtk2hs ?

It seems webkit-sodium couldn't use the latest ghcjs-dom interface.

Engine.hs in webkit-sodium change its imports for ghcjs-dom in commit 43d63e2.

But I couldn't find such interfaces in older ghcjs-dom version.

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

Note: installing in sandbox.

src/Language/Javascript/JSaddle/Value.hs:116:29:

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:
ExitFailure 1
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)
cabal-install version 1.22.4.0
using version 1.22.3.0 of the Cabal library
System: 4.0.6-200.fc21.x86_64

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

Clicking on the Freecell example to try it in my browser, for example, leads to an unplayably slow game.

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.

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!
