I started to learn it back then via ruby-gtk2. It was not
the best experience but I learned several key things
pertaining to widgets and the UI. Then came gtk3; it was
in some ways worse than GTK2, but it also brought a few
improvements such as the partial CSS support. I always
miss that when I use e. g. wxwidget.
Then came GTK4 though and things changed. Tons of old
things broke or no longer worked. Simple things such as
main_window_widget.move(0, 0) for top-left positioning
(I added an alias to this, .top_left in ruby and that
worked nicely); there are work-arounds to get the old
behaviour, but this is just one example of so many more
things that were eliminated. GTK4 is a GNOMEy-toolkit
and GTK5 will be even worse since it will be wayland-only.
"Interacting" with the GNOMEy-GTK devs is a total waste
of time and I am hardly the only one who had that
experience. For GNOMEys it may be a useful platform,
but GTK no longer is a general toolkit really, despite
claims by the current GTK devs otherwise. Why would
we non-GNOMEys want to keep GTK on life support? There
really needs to be a toolkit that can work in a much
more de-centralized way. Sadly I also don't have a good
idea here, since funding is an issue and GUIs seem to
have taken a huge hit ever since the world wide web
became dominating.
Well, it is what was always considered to be a default toolkit. Sure, I like Qt and prefer such apps but you got a have the GTK installed anyway. It was always difficult to have general toolkit with it when you depend on dozens of dependencies, collection of libraries, not big fat libraries like in Qt, that you can deploy.
GTK4 changed a lot though, like they do not even try anymore, deprecated font dialog because that is better done with XDG portals, but such thing does not even exist. How will that work on macOS and Windows, it cannot? Or what they did with the menus. Toolkits should be user oriented and should not have vision, it just needs to work and provide controls, events, etc., you cannot even position windows in macOS and Windows with GTK4, that is not toolkit that works for users.
I am working on the IUP fork here https://github.com/gen2brain/iup-go , one toolkit to handle them all, and I did my best for GTK4 backend, but from 14 drivers/backends I worked on, it was the worst experience and I had to fight battles with it.
GTK3 has nice, conventional looking interfaces. Developing for it always felt insane, but the advent of AI has completely removed the friction so I've had Claude build me quite a few apps using it because I like the look and it's easy to navigate.
i've been writing Haskell GUIs for a few years and mostly stick to react-banana or reflex because wiring up gtk-gi signals manually gets messy fast. The Elm architecture pattern here looks clean on paper but I'm curious how you handle async events from the widget tree without ending up in callback hell. Did you end up wrapping all GI callbacks in a channel that feeds into your update loop?
I think it depends on your district. On some distros (looking at you arch!) I think GHCup and keeping things in /home and out of your system package manager is the better approach.
That said, I never had issues with Pandoc on any distribution. But I have struggled with Pandoc extensions, before I got NixOS (and flakes).
Haskell packages in arch are dynamically, rather than statically, linked, which pulls in a large amount of transitive dependencies (reportedly in the neighborhood of a gigabyte). The maintainer has a pretty reasonable (to my eyes) explanation[1] as to why this is the case, but admittedly if I were an arch user I'd probably find it a bit annoying.
Is a widget a monad? Anyway, the examples in this tutorial are another proof that Haskell is the best imperative language!
It really is a great imperative langue! The IO monad is basically a better C, if you know how to wield the FFI.
Widget is not quite a Monad, in this instance it's a newtype around a pointer and classes that mimic GTK's own class hierarchy.
Replace `backdrop-filter` on `.backdrop::after` with `filter` on `.backdrop picture` for a free scrolling performance boost.
Indeed the scrolling performance is awful, makes reading it less enjoyable, especially when the topic is GUIs!

Are people still using gtk?

> Are people still using gtk?
Manifestly yes. There's even a list of GTK4/Adwaita apps available here: https://arewelibadwaitayet.com/
McCLIM is better

> import GI.Awd qualified as Adw
please tell me that's a typo
possibly enabled by lsp (Adw.foo -> "foo found in GI.Awd, import it with the name you used?")
yeah seems to be a typo, it is "Adw" and not "Awd", phew

Is Haskell in this case just binding a local HTTP port that users then hit with the browser? Or is it like a Tauri/Electron type of thing?
bro takes 2 years to make a todo list
Just keep in mind that some people like me avoid Haskell and the huge package mess it causes on Linux. Pandoc is infamous for that. Just stick to C++.
My Haskell experience on NixOS is wonderful!

Does your distro not statically link Haskell libraries the way it’s meant to? Installing pandoc only requires libgmp.
That is entirely your distribution's fault. ArchLinux has a user-hostile packaging approach which I do not experience in Fedora.
What does Arch do in particular to cause a mess? It's been a hot minute since I last used it and surely didn't use pandoc back then.

They build and link all Haskell libraries dynamically.
Arch Linux approach to python/haskell packaging is a great case study of what not to do...
Quite right, indeed
I completely avoid any haskell package in Arch and just build it with Stack, it's usually simple.
