ihaskell VS haddock

Are you referring to IHaskell: https://github.com/IHaskell/IHaskell?

Note that we do have the IHaskell kernel for Jupyter, so we don't have to be that jealous.

More info: https://github.com/gibiansky/IHaskell/issues/1251

I'm stymied trying to import a package. It's Graphics.Matplotlib. (See here.) I'm wanting it for my IHaskell, but when I add it to the IHaskell stack.yaml

That looks like a generic front-end error for when the back-end is unavailable, the back-end error should be more informative, but I don't know where exactly you can find it. At this point it might make sense to open an issue on the issue tracker of IHaskell, they will be able to give you more useful answers.

​ curl -sSL https://get.haskellstack.org/ | sh git clone https://github.com/gibiansky/IHaskell cd IHaskell pip3 install -r requirements.txt stack install --fast ihaskell install --stack ​ jupyter labextension install jupyterlab-ihaskell # did not work ​ stack exec jupyter -- notebook

I haven't actually used IHaskell, however, the png file is presumably created in whatever the working directory is when the script is running. The IHaskell wiki says:

Happily, at Well-Typed we've got a client funding improvements to Haddock performance, so this should get better in the future. The work isn't yet finished but there are some good improvements already: https://github.com/haskell/haddock/pull/1594

The link in the synopsis not working is also fixed in Haddock but hasnt made it in to the version bundled by GHC yet: https://github.com/haskell/haddock/pull/1458

The synopsis opening when searching has actually been fixed in https://github.com/haskell/haddock/pull/1486 for haddock, but don't think it has landed in hackage yet. I created https://github.com/mrbech/hackage-synopsis-search-hider to apply the fix via a chrome plugin until hackage gets updated.

/* ==UserStyle== @name Hackage Synopsis Search Hider @namespace github.com/openstyles/stylus @version 1 @description A userstyle that applies the fix in https://github.com/haskell/haddock/pull/1486/files to hackage.haskell.org @author https://github.com/mrbech/ ==/UserStyle== */ @-moz-document domain("hackage.haskell.org") { #synopsis details:not([open]) > ul { visibility: hidden; } }

This proposal is based on an idea by Haddock maintainers.

I've opened a feature request to add a visible search bar exposing the quick jump functionality in haddock.
