mtl-style-example VS hackage-server

Re: effects libraries, it's probably worth starting with e.g. https://www.fpcomplete.com/blog/2017/06/readert-design-pattern/ https://www.parsonsmatt.org/2018/03/22/three_layer_haskell_cake.html https://github.com/lexi-lambda/mtl-style-example if you're just getting familiar with the ecosystem. I'll add, anything written by the the people I linked to in this comment is probably worth reading as well.

Personally, it felt to me like, once I really understood monad transformers (https://hackage.haskell.org/package/transformers) and mtl (https://hackage.haskell.org/package/mtl), the reasons they both exist and how they are distinct, how you use them generally and what common patterns are around structuring your app (see e.g. https://github.com/lexi-lambda/mtl-style-example and the 3-layer-cake link someone else provided here for two), a lot of stuff in the ecosystem suddenly became comprehensible and useful to me, in a practical, "real world" way. In fact I'd go so far as to assert that getting comfortable with mtl in particular is the biggest single step you can take to being able to build arbitrarily useful real-world apps that are no longer toys.

Very cool! Is this open-source? It would be cool to add a few sources to this (like https://hackage.haskell.org).

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.
