Cabal VS hackage-server

Also, there's already a cabal RFC to support toml: https://github.com/haskell/cabal/issues/7548

Cabal has a lot of dark corners once you stray from the happy path. Just checked and I'm currently subscribed to 37 threads on the issue tracker, and I'm not a maintainer. A lot of these are related to lesser-used features like cabal scripts, environment files and doctests (though I think all of these things would used more if they were more reliable), but there's also plenty of stupid stuff like: - https://github.com/haskell/cabal/issues/3313 - https://github.com/haskell/cabal/issues/8527 - https://github.com/haskell/cabal/issues/8391 - https://github.com/haskell/cabal/issues/7789 - https://github.com/haskell/cabal/issues/6888 - https://github.com/haskell/cabal/issues/6999 - https://github.com/haskell/cabal/issues/5271

By the way, there are some open issues for the command to add a package in Cabal.

That's interesting. Could you could open a an issue about this? https://github.com/haskell/cabal/issues

At the moment, cabal-install doesn't support hpack natively but if the project can be build with cabal-install, you can run hpack manually to produce the .cabal file and utilise dr-cabal after that :)

Hm thanks for that, could try out some of those ideas. Here's the github issue i opened for this: https://github.com/haskell/cabal/issues/8580

Would really love it if the Cabal documentation had this as its own, highly visible entry. I submitted a pull request to that end.

Sometimes cabal's output is confusing with regards to optimization levels: https://github.com/haskell/cabal/issues/6221

3. https://hackage.haskell.org is the primary place

I used to see pandoc described as a "virus that makes people want to install Haskell", but I think someone must've figured out binary distribution.

The closest analogue to ZIO is probably the RIO monad + Has* type classes from https://hackage.haskell.org . /package/rio . (But ZIO is a bit richer with the typed error channel.)

Not yet, first hackage-server has to be updated to Cabal-3.8.1.0, see this hackage-server ticket

So I was working on this tool pysearch.com for doing deep semantic searches of python docs by program analysis inferred functionality when I noticed that every library's docs seem to be in a different format hosted in a different source. This would be fine if there was also a standard format hub for all the libraries on pypi or something, but it looks like even readthedocs doesn't contain everything. I find this a bit odd given the existence of tools like pydoc for doing something like this locally. Originally, I was hoping to find something like hackage for haskell, as I was hoping to build a natural language version of hoogle. In the meantime I've gotten pysearch to work by setting up custom rules for each doc, but this is kinda unsustainable.

The other source of haskell documentation is hackage, which features both libraries and higher-level GHC modules. Using hoogle (!hoogle or !hgl in DDG), you can search these docs by module name, function name, or even type signature.

Questions re. library support are best found by searching Hackage. A cursory glance indicates ‘yes’ to both, though I’ve never used them. Generally, there is a library to do what you want, though given the Haskell community’s relatively small size and finite time, it might not be as up-to-date as you like. That, of course, is a problem that you can fix and contribute upstream, and the Haskell build tools have good support for using your own fork of a given library.
