Software devs: what's the good GUI library or framework or language with excellent 2D support? I have multiple visual programming ideas, and I want to be able to build or prototype them quickly. Think: software for building diagrams or flowcharts, essentially.
Requirements:
* FOSS
* 2D graphics
* cross platform native desktop applicationNice to have:
* fast, efficient language
* web and/or mobile supportNo, thanks:
* Electron
* React@thezerobit I personally enjoy Qt (with C++) -- but I think you knew about this option without my reply. Pros: decent OOP abstractions, cons: Qt is a framework, it is nudging you to program in a specific style.
More relevant: @aeva are working on a visual programing thingy and have a very long thread (tm) about their experience. I think they used SDL for graphics and audio; I will link to the thread in a reply once I look it up -- it has good ideas even if you choose a different route.

@anton @thezerobit I'm SDL3 for graphics. Specifically I am currently using their basic "renderer" module, not their "GPU" module. I am also planning on switching to using OpenGL ES2 to do the drawing (while retaining SDL3 for window and rendering context creation, input event management, and eventually using their audio API as a fallback audio backend).
I'm not presently using SDL3 for any audio or MIDI functionality, I'm just calling the relevant platform APIs directly at the moment.

@anton @thezerobit I highly recommend using a generic 2D graphics API (SDL3, Cairo, etc) instead of an opinionated toolkit like QT, as visual programming languages tend to follow eccentric interaction and presentation conventions and you don't want to be fighting with your tools every step of the way.

@anton @thezerobit the thread starts with me hashing out ideas and planning out the semantics I want before diving into prototyping. I went into it with some very specific ideas for using 2D procgen to solve things I find irritating about conventional visual programming languages like wire placement. I still intend to implement some of these ideas, but I've found early on that doing things simplest way possible was quite tolerable, and so my attention has mostly been on the synth pipeline.

@anton @thezerobit in general, I've prioritized ease of development over long term correctness, and through the benefit of experience I've mostly avoided painting myself into a corner architecturally. This has allowed me to build out all of this in about 7 months. I hired a friend to help out for about four weeks, and in that time he set up a build system and replaced pygame with SDL3 for me.

@anton @thezerobit and by far the biggest time sink by a long shot has been fighting with Linux's utterly slapdash support for multitouch screens.

@anton @thezerobit it also helps that the language runtime itself under the visual representation was something I already knew how to build, as this project follows many prototypes, and other language experiments before it

@anton @thezerobit my recommendation is to find a 2D drawing API that you like, and experiment with drawing the basic primitives of your language, and seeing if it scales up acceptably. Once you have that, you can work out how to make those experiments parametric, and how to connect them to the underlying runtime of your language. Pick interaction semantics that are easy to implement. Every button in mollytime triggers on mouse down instead of up for example.

@anton @thezerobit this project has taken up the majority of my free time and spare thought this year. I have no regrets. It is magic. It has been very rewarding and I highly recommend making visual programming languages.

@aeva
Wow, thanks for sharing your experience and thoughts. I've spent some time working in the game industry, too, albeit nearly 20 years ago (Wii, PS2). A lot of what you said makes sense, I do think I need to probably build the elements from primitive graphical elements to get an interface that isn't jank. I'll have more to say when I've had some free time to look into what you've been working on a bit deeper. Cheers! -

Cheers!@thezerobit I am happy to elaborate on anything or chat more on the subject if you want someone to bounce ideas off of and so on. What games did you work on?

That's kind of you to say, @evan . I'm still somewhat concerned people will think I'm spamming the timeline.
@pluralistic does it and people don't mind; but I'm not the same kind of writer.
Really, this ought to be a blog post, not a thread; I should really reactivate my blog.

Vi ho mai mostrato il porta PC portatile da parete che feci qualche anno fa? Stasera ho smontato tutto per sfilare e ripulire la PS4 accanto.
Quello bianco è un pannello in PVC di recupero dalla galvanica, lo buttavano via, poi c'è un profilo ad angolo in alluminio e pellicola lucida effetto carbonio del negozio di cinesi.
Si nota la presa d'aria che ho fatto di sotto verso il centro?

@mpjgregoire this is a great thread. Thank you!

@mcc@mastodon.social absolutely — they just look nicer that way.

That said, about 13% of delegates voted non-confidence, so support is
not unanimous. I ran into delegates who lamented that people they knew who'd
always supported the Conservatives wouldn't vote for the party with
Mr. Poilievre as leader.12/12

5. Pierre Poilievre. Members of the CPC like him personally, like where he
stands on issues, like the way he's a fighter, like the way he's brought new
support into the party. I ran into one guy who said that he'd be another
Robert Stanfield, someone who'd be an excellent PM but who would never win.
But I didn't run into anyone who'd admit to opposing Mr. Poilievre; there was
no one organising against him; there were not even anti-Poilievre buttons
around.11/n

I did bring up Pres. Trump a few times,
and when I did so, the response I received was that he was doing crazy things
and that he was bad for our electoral chances. But people weren't really
talking about Pres. Trump one way or another, so I can't claim to know that
that was the general feeling.10/n
-
4. Trumpiness. The party struck me as essentially the same as it was twenty-five
years ago: same sort of spirit, same sort of issues, even many of the same
individuals (I ran into people who fought in the Clark-Mulroney struggle). I
have to say that there wasn't much discussion of Canada-US issues; mostly I
talked about domestic policy (the CBC! Zoning!) or current regional/national
politics (John Rustad was terrible!).9/n
