haskell-mode VS ivy-rich

You can use GHCI's debugger through Emacs's haskell-debug-mode (part of the haskell-mode package), and probably through other editor/IDEs as well, a programming editor like Emacs or Vim simply needs to be able to run a GHCI session and send commands to it.

No, I was only using haskell-mode. So I guess this is LSP's fault, then. Not Emacs's fault and not haskell-mode's fault.

If I made it sound like there's something like IntelliSense today, apologies! We've got <https://github.com/haskell/haskell-mode/blob/master/haskell-...>, but it's type-a-command-and-do-a-search: it's not linked in with completion directly in the setups I've seen.

(In practice, I'm usually starting from a slightly different place: I know I want a Frob and I've got a This and a That, so I do :hoogle This -> That -> Frob and get some options. The thought-process is working backwards from the goal more than forwards from one key object in focus. A different way of working, but I'm not convinced it's less effective.)

My point though was that it's an engineering issue, not a fundamental language limitation. ie not a reason all future languages should shun haskell features. The building blocks to do better at completion than haskell curently does are there.

check if you have any similar config to what caused this issue: https://github.com/haskell/haskell-mode/issues/1777 for me

Package-lint has been on my list, but the maintainer, MELPA's Steve Purcell, has been hesitant about NonGNU ELPA in the past (see this discussion), so I have skipped his packages for now, and also because most of the packages he maintains have a "broken" version tag, most of the time -- the reason here is that MELPA adds these manually, and since he understandably is targetting MELPA, there is little interest from his side to fix that.

You can see the expected output in this PR description.

I use haskell-mode. It has a shortcut for loading a module into REPL, and it also runs hasktags for me. That's literally all I use.

Just as a note from my poking around, this is the "official" way to use a nix-shell with haskell-mode: https://github.com/haskell/haskell-mode/blob/3a019e65b504861d7ea23afbfecd14e5ef63e846/haskell-customize.el#L77

The screenshot might picture marginalia as another user already mentioned. What package you want to use depends on the completion framework you are using. For built in completion framework together with vertico, icomplete or selectrum marginalia is the package you want. If you are using ivy instead, then ivy-rich provides this functionality. Surely helm has some similar functionality.

Some examples of what I am talking about: https://github.com/Yevgnen/ivy-rich/blob/master/screenshots.org

From looking at these examples, no. This is what the shortdocs look like: https://imgur.com/5pIu9A6.png. A brief summary, grouped by kinds of operations with examples. Built into Emacs, linked to from the *Help* buffer no external documentation is required.

Having been a longtime user of ido and smex, I decided to give ivy/counsel a try. Overall, I like it very much. I like that the key-bindings are more consistent with Emacs conventions, and I like how it can be extended with packages like ivy-rich and all-the-icons-ivy-rich to add useful auxiliary information and give it a more modern looking interface. But there are still a few things that I can't wrap my head around, and for which I couldn't find a satisfactory answer online:

fyi, opened an issue on this: https://github.com/Yevgnen/ivy-rich/issues/102
