Upgrade to Halogen 6

[simonolander]

Hi!

It would be much appreciated if this project was bumped to Halogen 6. It seems like all the necessary dependencies are at 0.14.0 since a little while back. I gave it a shot, but I know too little about the library to translate the bus event source things.

I have a quick update: I'm going to release a small state management library for Halogen to replace the bus / event source implementation used in Real World Halogen. Once it's out I can start on the proper migration of this repository to Halogen 6. Hold tight -- it won't be too long!

I have a quick update: I'm going to release a small state management library for Halogen to replace the bus / event source implementation used in Real World Halogen.

I recently bumped a project of my own to Halogen V6 and as it was based around this RWH project I figured I'd do that too in tandem.

Other than the busEventSource replacement, here is what seems to be needed to make the compiler happy:

• Bumping the package set in packages.dhall to be compatible with the 0.14.1 compiler
  • Spago (0.20.1) suggested adding many more dependencies to the spago.dhall (and dropping two of them)
• Removing each 'Just' from each of the HE.onXXXXX event handlers
• Replacing the SProxy and F.FormProxy with the new Proxy (from Type.Proxy)
• Removal of HH.HTML surface type from H.Component signatures
• Each use of CA.prismaticCodec has an new extra 'name' field as its first parameter, which needs adding
• Replacing the one use of H.tell in Main with the new H.mkTell
• Adding the new timeout field that Affjax has added to its request type into the defaultRequest function (in Conduit.Api.Request)

The above was enough to build, but the following was just a new compiler suggestion in the modules with Formless forms:

• Adding the compiler's suggested top-level (edit): inline Row kind signatures for Formless newtypes

If anyone waiting on V6 would like to see those changes above compared to the main branch here, I've pushed a branch of RWH that builds at the moment over here. There should be 1 commit that corresponds to each of the points above if you'd like to see (or use!) the differences.

That branch uses a temporary fix for busEventSource that I'm currently using in my own project that uses halogen-subscriptions (based on something kritzcreek linked on Slack). But I'll change to the new state management library that Thomas mentions above once it's available.

Happy to send a PR upstream to here for part or all of the points listed above above too, if you'd like. 🙃 I'm sure there are things that you'd want in a proper release that I've missed also. I didn't touch the CI file, for example. And the only documentation I edited was the example given for how to use busEventSource.

Thanks, @and-pete! I'll ping here when I've made an update for the busEventSource replacement, and then I'd be happy to use your work as the basis for a v6 update. I will also want to update some documentation and make a few other improvements and bugfixes to the project -- but that can come later! It will be fantastic to be on Halogen 6 regardless.

The busEventSource replacement is available here: https://github.com/thomashoneyman/purescript-halogen-store

I've got to add docs and publish it, but the code seems to be working well and hopefully it's a smooth replacement over here!

Closed in #82 -- thanks, @and-pete!
