areweguiyet VS egui

The organization behind QT (QT Group) has pretty onerous licensing terms.

My understanding is that it's $3,950 per year just to develop using their libraries on your own computer if you ever in the future intend to commercialize a product using QT. Transitioning from the open source license to the commercial license is something you can do but it's not the happy path and their FAQ seems to indicate that it comes with some sort of penalty.

Something like Slint (Rust based but includes CPP and JS bindings) is not as comprehensive (yet) but it's more modern and the licensing terms are significantly more in line with software industry norms.

GPUI from Zed is also something to monitor: https://www.gpui.rs/

Also, in general you can find an extensive list of Rust-based native UI libraries here: https://areweguiyet.com/

I would suggest that nearly every person on this website is a developer. Both C and C++ let you shoot yourself in the foot quite easily, but at least C++ has RAII.

If you're referring to Rust, it's just not there yet for anything serious: https://areweguiyet.com/

I normally use python to do some quick data analysis, with pandas/polars/pyspark/...

But I've started to use rust more and more in the last few weeks and really start to like it.

Does anyone have experience doing data analysis with rust, and would you recommend it over python?

And are there any resources like https://areweguiyet.com/ but for data analysis?

You still haven't said anything about why those existing frameworks don't count. Again, they are used in production and do exactly what a gui framework is supposed to do. Sure they may not have all the features of the frameworks that have existed a decade before rust even existed but the issue is time not rust itself. They very clearly can be used to build complex UI without inheritance. Since you mentioned it, you should probably actually look at it https://areweguiyet.com/ the page clearly says that GUI frameworks do exist in rust.

The web site https://areweguiyet.com/ has a list of GUI libraries for Rust.

I haven’t tried any yet as I lack the time, but it can be a good starting point.

Iced and Slint where interesting when I looked at that, and Slint may be done by former Qt developers.

I also hope that it is consistent with the goals mentioned at https://areweguiyet.com/

Thanks for the feedback!

It is definitely fixable. Take a look at https://github.com/emilk/egui/issues/996 for some examples of how others have styled egui, or try out https://app.rerun.io/

Styling is done with `ctx.set_style`, but creating a nice style isn't very easy at the moment (basically you'll have to tweak constants in code, and then recompile). I'm working on making it easier as we speak though!

Nothing is wrong with that, it’s rather a workaround, ultimately I am trying to have one language only including the UI too (been playing with egui),so I don’t have to use JavaScript.

FWIW, I opened an issue: https://github.com/emilk/egui/issues/4046

That's fair. I don't have experience with other immediate mode libraries. It's good to hear that it's not an intrinsic limitation

https://github.com/emilk/egui?tab=readme-ov-file#layout Here the author discusses the issue directly. They note that there are solutions to the issue, but that they all come with (in their opinion) significant drawbacks.

For my use case, if I have to do a lot of manual work to achieve what I consider behavior that should be handled by the framework, then I don't find that compelling and am inclined to use a retained mode implementation.

It totally depends on what IoT and what purpose, for example:

IIoT/PLC/industrial automation: most likely you will have to use vendors software, most if the time it’s crap, and a mix of several tech stacks like MSSQL/C#/C++

Sensors and such: depends on what are you building or using the sensors: the protocol mostly is MQTT, and if you would store it in a db postrrsql, elasticsearch, surreldb, influxdb among the most I used.

Robots/drones: on what I build, I use protobuf/grpc for performance and cross-language and direct linux socket io, and where needed websocket but mostly for any web interaction rather than the protocol itself. The tech stack for those, the embedded side is up to you or sometimes based on the sdk you are dealing with, the backend/frontend however, I used to use go/nodejs and for frontend svelte or a simple js library/framework, but recently I’m shifting and redoing everything in rust, embedded, backend and frontend (using something like egui https://github.com/emilk/egui).

When it comes to IoT, I try as much as possible to stay away from python unless you are scripting something else done in go/c++/rust, look at python as a glorified bash script, it’s useful for that or other data science work, but not in IoT.

Same goes with other tech you mentioned, it might suit one case but not another, for example, MQTT is good for sensor IoT type, but good luck controlling a drone with it, mongodb might be great to store a fleet of robots with its access credentials and such, but if you try to use it to store realtime data, it might not perform as expected, and so on.

AFAIK the Rust equivalent to C++'s Dear ImGui is egui.

The creator of Rerun (Emil Ernerfeldt) also created egui [1], an immediate GUI library for Rust. The library is similar to Dear ImGui but it is written in Rust and can be used for desktop and web apps (compiles to WASM and uses WebGL, demo [2]). Desktop apps can target OpenGL (does not display correct colors on macOS, does not work in VirtualBox on Windows) or WGPU (uses native APIs for each platform, works without any problems, but the binary is a big larger).

> [...] you can build UIs that are snappy and keyboard driven.

That's not an advantage that is exclusive to TUIs; after all, you're running your TUI inside a graphical application that emulates a terminal. (Unless you're rocking an actual VT102, in which case I bow down to you.)

In fact there's an entire class of applications that are extremely snappy and keyboard driven, by their very nature: games.

Some people have taken to writing GUI apps like you'd write a game, and the effects range from OK to fantastic. Check out Lagrange (https://gmi.skyjake.fi/lagrange/), AppManager (https://tildegit.org/solene/AppManager), Dear ImGUI (https://github.com/ocornut/imgui), egui (https://github.com/emilk/egui), and many others.

Honestly, frontend development especially with all these crowded frameworks and libraries always confused me so pardon my ignorance, which is why in a project I’m working on right now I’m trying not to use js, instead I’m using egui [1]

Zola is a static site generator and it’s crazy fast, using one binary only [2], also there’s Blades [3], same concept but supposedly faster, never tried it though.
