ihp VS penrose

I found IHP straightforward:

https://ihp.digitallyinduced.com/

despite not remembering much haskell!

This assumes you can get past nix for the install.

I find IHP well-designed. I just wish the licensing scheme were more transparent.

You can find the docs at https://ihp.digitallyinduced.com/ and some getting started videos at https://www.youtube.com/watch?v=PLl9Sjq6Nzc&list=PLenFm8BWuKlS0IaE31DmKB_PbkMLmwWmG

In case this got you interested in Haskell, and you want a good way to start your Haskell journey (and have something to apply the optimization handbook to), check out IHP. It's the Rails/Laravel of the Haskell world. You can start here https://ihp.digitallyinduced.com/Guide/index.html or check it out on GitHub here https://github.com/digitallyinduced/ihp

At IHP we've been using Algora for a while now and it works really great. Here's e.g. one PR that was merged last week with a bounty attached https://github.com/digitallyinduced/ihp/issues/1621 Everything was set up in less than 15 minutes and ioannis and zafer have been super helpful with any questions we had.

In general I think this is a good direction and an interesting take on the open question around sustainable open source. Congrats on the launch and keep up the great work! :)

You could contribute to IHP! We have some great docs to get started here https://github.com/digitallyinduced/ihp/blob/master/CONTRIBUTING.md And we have some low hanging fruits in GitHub issues for you to get started with, e.g. https://github.com/digitallyinduced/ihp/issues/1601 (also there's always lots of activity in the IHP Slack, in case you have any questions/need help)

There is a fork that compiles to js https://github.com/ghcjs/ghcjs compiler, and I believe the official glasgow compiler is working towards also supporting js/wasm (although I don't think they are supported as of yet).

I don't know anything about Haste, but you can get GHCJS 8.6 (or 8.10 with a bloated executable) via nix fairly easily or alternatively wait until the JS target recently merged into mainline ghc gets production ready: https://engineering.iog.io/2023-01-26-ghc-update.

Ah GHCJS does have this header: https://github.com/ghcjs/ghcjs/blob/ghc-8.10/lib/boot/data/include/stg/DLL.h

It seems like https://github.com/ghcjs/ghcjs/issues/821 is a rigid dealbreaker for any sizable project.

About the FFI: GHCJS extended the FFI to support inlined JS, named arguments, etc. See https://github.com/ghcjs/ghcjs/blob/master/doc/foreign-function-interface.md For now the JS backend only implements FFI calls similarly to native FFI. The rest will be open to discussion later (e.g. in a ghc-proposal) and should take into account the Wasm backend so that the same user code compiles with both backends as much as possible.

Other than that, I ran into a GHCJS and Miso bug, but they weren't too hard to solve.

There are a bunch of open branches. And yes, there is ghcjs support in haskell.nix, see this comment.

When I compile the ghc-8.8 branch locally, I get a number of test failures from the test suite. I'm not sure exactly how to fix them and they aren't currently my highest hobby priority.
