Re: [Haskell-cafe] Cabal and cabal-install minor release (1.22.2.0)

I already do regular binary builds: every time I do a Stackage Nightly or LTS Haskell build. If it would be useful to share those binaries somewhere, let me know. Of course, sharing the entire binary package database for each nightly build would become a pretty hefty storage burden, but we can probably figure something out around the LTSs.

I’d like to add Windows support, eventually (https://github.com/mietek/ halcyon/issues/42).

My main focus right now is enabling the distribution of Haskell applications in binary form, without requiring the cooperation of application authors. To be specific, I’d like the user to be able to say `halcyon install idris`, and get the latest version of Idris installed on their system in 5-10 seconds.

Preposterous? This is how Halcyon already works: https://halcyon.sh/tutorial/#install-the-app

Of course, this requires the application to be built ahead of time, which in turn requires version constraints to be declared for the application.

Now, application authors don’t seem eager to declare version constraints. However, declaring a particular version of Stackage LTS is equivalent to declaring a full set of version constraints (https://github.com/mietek/ halcyon/issues/41, https://github.com/mietek/halcyon/issues/40).

It seems to me that adopting Stackage LTS should reduce the binary distribution problem to automating the process of performing regular builds across many platforms.

Looking forward to your comments.

Thanks, Ryan.

Binaries of cabal-install 1.22.2.0 are now available in Halcyon on the following platforms:

That's quite impressive! Have you considered adding Windows support? Our release process could use some automation in this area.
