Sample App won't build because of ghcjs-base and github timeout about miso HOT 15 OPEN

@caryoscelus it does seem like foreign imports are supported, but not exports. This should be okay, I will get back to you as to how long it would take to update.

It is an issue yea, but nixpkgs might not have the old GHCJS (which just happens to be the most stable). So upgrading isn't an option it seems until the latest GHC supports FFI for its new JS / WASM backends.

Just tried it, and it built!

Not sure if you want to keep this open or not since its solved for me, but it might save someone else some time who decides to try it during this weird interim state.

@dmjio for my purposes i want to be able to build everything myself so different cache doesn't make much difference. right now i'm still evaluating whether to use Haskell&Miso or PureScript, though, since latter seems to have easier support for 'advanced' browser features (WebRTC, IndexedDB)

from miso.

Are you using cachix as described in README.md ? Using the cached deps. is usually a better experience.

from miso.

Ah, no, I don't think so. This was a new machine and I haven't set up cachix on it.

I'll try that and report back, hopefully that will unblock me. Though this still seems like an issue?

from miso.

@joelmccracken definitely let me know if cachix does / doesn't work for you. Cheers 🍻

Let’s just hope Google indexes it for others ;)

Can I get an invitation? It seems that to create an account I need to have a @haskell-miso.com email address

i've just run into this issue and honestly i don't find using binary cache can be considered a solution. is there any other possible workaround? (i'm fairly new to nix inner workings, but i'm sure it should be possible to extract required ghcjs package and update it to not use git://)

if there's no workaround, what is the estimate of new ghcjs with necessary features being available?

from miso.

Using the binary cache is the fix for now. Regarding when miso will be updated to use the new JS / wasm backend I think it depends on when FFI is supported, among other things (template Haskell).

unfortunately that sounds like the whole setup is effectively not fully open source :(

There’s no corporate pay wall, but if you build at the old hash with the old version of nix it should be reproducible.

from miso.

@caryoscelus If you'd prefer we can use our own binary cache, with our own s3 bucket and sign our own packages - cachix just makes this more convenient and our closure fits in the free tier. Furthermore, there are plans to upgrade, it's just that the JS backend has no binary distributions yet, so users would need to build / maintain their own GHC.
