    I've recently tried that and gave up (https://github.com/LambdaHack/LambdaHack/issues/248). Perhaps it's possible to statically link SDL2, but I learnt it's impossible to statically link the OpenGL and X11 libraries, so you end up with a partially statically linked binary (I didn't manage to obtain even that).

    I did some plotline sketches on the github wiki of my project, but never used them so far. Not much use from the other musings there, either. Instead I tweak the templates for procedural generation directly in the code (game content part of the code, to be precise) and get a lot of mileage out of that. The only page of the wiki I got lots of benefit from is the derivation of the simplified formula for calculating speed, distance and damage of projectile from their weight: https://github.com/LambdaHack/LambdaHack/wiki/Item-statistics#projectile-velocity-and-distance

    Around a decade. No, one release per 1-2 years. The differences are quite large, both gameplay and, even more, UI, in particular in using ready fornts, then custom fonts, then many fonts at once. See the changelogs (that's only for the egine, but that's where most of the changes are made): https://github.com/LambdaHack/LambdaHack/releases

  • Egui 0.27 – easy-to-use immediate mode GUI for Rust
    3 projects | news.ycombinator.com | 27 Mar 2024
    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.

  • Immediate Mode GUI Programming
    15 projects | news.ycombinator.com | 15 Jan 2024
    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.

  • Ask HN: What software do you use for IoT devices and server
    1 project | news.ycombinator.com | 25 Dec 2023
    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.

  • GUI library for fast prototyping
    3 projects | /r/rust | 6 Dec 2023
    AFAIK the Rust equivalent to C++'s Dear ImGui is egui.
  • Rerun 0.9 – a framework for visualizing streams of multimodal data
    4 projects | news.ycombinator.com | 5 Oct 2023
    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).

  • Textual Web: TUIs for the Web
    9 projects | news.ycombinator.com | 7 Sep 2023
    > [...] 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.

  • My Journey Away from the JAMstack
    3 projects | news.ycombinator.com | 31 Jul 2023
    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.
