eframe_template's Introduction

Hi there 👋 😊

I'm Emil Ernerfeldt, and I like Rust!

I'm the creator of egui, the friendly GUI library.

I am also the co-founder of Rerun, a company making visualization tooling for computer vision and robotics.

Follow me on twitter @ernerfeldt for news about egui and Rerun :)

eframe_template's Issues

clarification on how to deactivate the cache in development

In the ReadMe you have mentioned

assets/sw.js script will try to cache our app, and loads the cached version when it cannot connect to server allowing your app to work offline (like PWA). appending #dev to index.html will skip this caching, allowing us to load the latest builds during development.

Please could you indicate where to add the #dev. Should I add it to the filesToCache variable inside the sw.js, should i rename the index.html at the root folder or should I append it to the content of index.html at the root folder.

Sorry if my question seems dumb

Progressive Web App Support

Would be cool if this template could include the files to act as a progressive web app, i.e. be installable from the web to an offline capable version.
There is this example for another web frontend framework we could use as a template:

No function "load" in trait epi::App

Hi, when the template is compiled with the "persistence" feature, it fails to compile it, because there is no "load" function in the trait epi::App, only a "setup" function.

Steps to reproduce:

Create Template
Clone the repo I just made via Create Template
cd egui_test
cargo run --release

OS: Windows 10

Let me know if you need any more info about my system/rust setup.

How can the grey margins on the web version be removed?

The start page for my app looks like this natively:

and like this on the web (I am using Firefox):

It has the same grey margins as the demo:

How may one remove these?

*.bat files dont work for directorie names with spaces

The file build_web.bat from #46
does not work if run from within a directory with Spaces.

I just tried it in a directory OneDrive - CreateCtrl AG and the script tried to find the wasm file in a directory OneDrive.

PS C:\Users\Simon\OneDrive - CreateCtrl AG\programms\test_eframe> .\build_web.bat

PS C:\Users\Simon\OneDrive - CreateCtrl AG\programms\test_eframe>

from a directory without spaces e.g. C:\Users\Simon\Downloads\eframe_template it works flawlessly.

I dont know how common paths with spaces are (in windows) -- I guess if someone (e.g. @Jimskapt) has some time this could be fixed. But it's probaly not a huge problem.

crash when resizing window (exit code: 0xc0000005, STATUS_ACCESS_VIOLATION)

The default app crashes when resizing the window in both directions ( using the corner ). Resizing vertically only or horizontally only doesn't crash at all.
I am very new to Rust and Eframe/Egui. Is there a way to remedy this issue ?
I am on Win10.

Demo app text box fails to bring up iOS keyboard

Attempting to use demo app at

https://emilk.github.io/egui_template/

and edit the text box results in no virtual keyboard being displayed, even though text box has focus and cursor within the text.

Using iOS 14.3 on iPhone XR, but also verified same results on iPhone 12 with iOS 14.4

Web build fails in workspace

While the wasm build works just fine if the crate is compiled in a standalone manner, it fails when the crate is in a workspace. To reproduce, create a workspace folder with the following Cargo.toml.

[workspace]

members = [
    "eframe_template",
]

Cloning the repo inside the workspace and running build_web.sh results in the following error.

Suggest users to use the `dev` profile while in development

For reasons discussed in this guide of another random Rust project, it could be considered bad practice to use release mode during development of Rust projects (especially ones with high complexity, e.g. GUIs). I'd suggest changing the Cargo.toml and README.md files to reflect this ideology.

Segmentation fault on WSL + VcXsrv

When running the template via cargo run --release, the example runs correctly:

But pressing the X to close the window or pressing File>Quit causes a segmentation fault:

LLDB Output:

Incremental compilation fails because of Rust analyzer invalidating build cache

The problem is tracked at rust-lang/rust-analyzer#12688

This finally explains why we didn't have this issue when we added trunk. The issue only started popping up after #81 where we added unstable web apis flag

[build]
rustflags = ["--cfg=web_sys_unstable_apis"]

The workaround mentioned is to use

[build]
target = "wasm32-unknown-unknown"

[target.wasm32-unknown-unknown]
rustflags = ["--cfg=web_sys_unstable_apis"]

you can remove the [build] section if you use rust analyzer vscode settings like me and comment out wasm when you need to work on a wasm project.

  // "rust-analyzer.cargo.target": "x86_64-pc-windows-gnu",
  // "rust-analyzer.cargo.target": "wasm32-unknown-unknown",

License

If the idea is to take this template, make modifications, and then build on that, shouldn't it have a license?

SW/Cache not loading due to wrong paths

If the template is hosted under a path, e.g. https://emilk.github.io/**eframe_template/**, the following elements will show 404 errors:

manifest.json
sw.js
icon_ios_touch_192.png

As a result, the service worker fails to load, and the PWA loses its offline/caching capabilities.

Console output for https://emilk.github.io/eframe_template/:

Uncaught (in promise) TypeError: Failed to register a ServiceWorker for scope ('https://emilk.github.io/') with script ('https://emilk.github.io/sw.js'): A bad HTTP response code (404) was received when fetching the script.

Cargo warning on build

I used Github to create a repo from this template. Without any modifications to the template, I noticed that running gave me a warning:

$ cargo run --release
warning: unused manifest key: dependencies.eframe.default-dependencies

Maybe this was intended to be default-features?

I'm on Rust 1.65.0 on macOS.

mind your cache

Hi, I'm trying to learn Leptos right now, but when I tried to run it's examples on a local machine I've seen just the leftovers from some eframe stuff I was doing before. When I refreshed the page that stuff was still there despite active Trunk with a Leptos app. Only force update helped (Ctrl+Shift+R).

I'm not saying that there is anything wrong with this template, but I encountered some confusion so I decided to share it. Also I know that there is code in this repo that is responsible for making cache work, maybe it's not 100% correct? is it possible to only ship it in release builds?

Text input is broken on web

Text input has really weird behavior using the eframe template in web. ~~For instance, copying/cutting text is not allowed (This also happens in https://emilk.github.io/eframe_template/).~~ Some other times, text input doesn't work at all except for the tab or enter keys. Surprisingly, this issue doesn't happen in the egui demo (https://egui.rs)

I'm guessing there's a problem with the index.html wrapper.

Cargo Subcommand?

TLDR

Would it be desirable to have a cargo subcommand to create a new project instead of only this template?

Explanation

I'm about to start a new egui project and was about to copy the template again. Then manually make the required changes again and realized this is probably something that should get automated. I'm considering building a cargo subcommand that would:

Ask the user for a project name and run cargo init to create the new project
Download the files from the master branch of this template
Prompt the user for answers and make the changes specified in the getting started
Prompt the user if caching should be disabled
Prompt if "presentation only" files should be deleted, like the readme. (Actually this is the only one I can think of right now but I'd go through the files and check)

This would provide a quick way to spin up a new project and allow users and easy way to opt out of caching at it appears some ppl would prefer not use it. It would also make it easier for ppl who are only testing and do not want caching at all like in this issue.

How can we remove all the DEBUG and TRACE tags in the console?

Trunk build only works at root directory

I'm not sure what component this applies to, so please let me know if I should submit this elsewhere.

The dist/ directory generated by trunk build only works if you place it at the root of the domain. What this means is that I can serve my app from https://example.com/ but not from https://example.com/asdf. Many free hosts do not give you root domain access, so this limits the place you can deploy to. (In particular, shared machines like https://example.com/~user/... will not work.)

You can replicate the issue with this template and a local webserver. The main thing to watch out for is that you must clear your browser cache each time because some aggressive caching will make it work when it is not (or vice versa).

git clone https://github.com/emilk/eframe_template.git
cd eframe_template
trunk build --release
cd dist
# clear browser cache
python3 -m http.server
# go to: http://localhost:8000/
# works
cd ..
# clear browser cache
python3 -m http.server
# go to: http://localhost:8000/dist
# breaks

I use python3 -m http.server as a local webserver, but any software should work, including putting it on a public host with user-level access (https://example.com/~user/).

Would it be possible to generate the build with relative paths so that my application can be located anywhere, even when it's not the root directory of the server?

Ubuntu: native build failed to run with "libEGL warning: DRI2: failed to authenticate"

Add `trunk` template alongside current template for web

trunk (https://trunkrs.dev/) is a complete build driver for wasm / web. It is very easy to use and has good defaults, and can easily be configured. I believe instead of using bash scripts and whatnot, it would be better to use trunk so that it's simpler to deploy and work with.

My suggestion would be to keep the scripts, but add a separate branch (or folder?) showing how it looks with trunk. Essentially it's just a simple index.html file at the root of the repository (which trunk uses to configure the build with), as seen like here.

First one I found and download, second - I remove from script (-fast arg isn't enough).
Now I can build my app for web. But it didn't work

Cannot compile on Fedora 36

Seems like some something called fontconfig should be installed. So this does not work with the instructions given in the readme.

When running example I get a smithay clipboard error

     Running `target/release/eframe_template_test`
2022-12-14T00:44:05.783911Z ERROR egui_winit::clipboard: Cannot initialize smithay clipboard without a display handle!

The example application runs however.

Only Rust as input? Can't write an WASM/Rust app using JavaScript?

Moving the mouse after expanding the sidebar causes it to go back to original size

Steps to reproduce issue:

Opened the example web app at emilk.github.io/eframe_template
Drag the bar on the right side of the side panel further to the right, release the mouse
Move your mouse

The side bar will shrink back to original size.

EDIT:

This happened on 2 computers in the browser, I also downloaded the source code, ran cargo run --release and the mac native compiled version does this as well. Really don't like this behavior.

Use serde(default) attribute for persistence state structs

Hi!

Currently if I do some things with the app template to have some things that change in the persistant state (e.g. if I click the increment button), then if I add a new field to the state's struct (TemplateApp) all the other fields are reset to their default value. This seems to be because serde doesn't know what to do with the field which isn't in the persistent state, so it kinda refuses to deserialize altogether, yielding None in the load() function, hence resetting all the struct to the default with the unwrap_or_default(). It seems like egui's main demo has this #[serde(default)] line so it seems like someone encountered this issue too at some point :).

It would be useful to add a comment explaining why it's there so that people actually understand what it's for.

Do you want me to create a PR or is it easy enough that you don't mind doing it? :)

Cannot copy text from text edit singleline

I downloaded the template and compiled it. The app has a text-edit-singleline widget with some text. When compiled natively, I can select "Hello World!" and copy it using Ctrl+C , but when compiled for the web, I am able to select the text but not copy it in any way.

Since copying the text was not working for the web, I tried to copy the text programmatically by doing the following:

// If the Copy button is clicked:
if ui.button("Copy").clicked() {
    // Clone the label text into the clipboard.
    ui.output().copied_text = label.clone();
}

Again, copying the code programmatically worked natively but not for the web. I tried this using Firefox in Android, and Firefox in Linux.
Any thoughts on why this is happening? I am writing a small app and I want to copy the text into the clipboard.

Fails with xcb error on startup

Under Linux (X11, Manjaro ARM) the demo app fails with:

[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
egui_template: xcb_io.c:269: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.
Avbruten (SIGABRT) (minnesutskrift skapad)

Edit: Updated rust toolchain from 1.51 ro 1.52. Now trying to run with either release or debug (just "cargo run") gives me:

ibEGL warning: DRI2: failed to authenticate

I have all xcb libraries I can find installed. Any test or further investigation you'd like me to do, just let me know.

Edit 2: I was using software rendering on the machine for some reason. Once I switched to the Panfrost mesa driver it all worked.

Thank you for coming to my monologue, and I hope you've had an enjoyable evening. Feel free to delete this issue if you like.

Cannot compile on Manjaro Linux Ruah 21.3.7

Hello! I've heard that egui is a great UI framework for making a UI on rust, that's why I've been dying to try it out. I'm not very experienced with C++ or C but I've been trying to learn rust doing some applications on the console and it's been great.

Aynway, I've forked this repo on my computer and tried to run it, the only thins I changed on the repo once it downloaded were:

I tried to compile but it gave an error that CMake was missing, so I installed it but maybe I don't have the correct version (currently I have 3.23.3)? I don't know could someone hep me please! Here's the complete error log:

Provide a simpler example using egui?

Hi
I have been trying to use egui for several hours and days and I don't understand how to use egui simply.
I'm not a pro dev but I've already buid UI with python.
I can compile the actual egui_template but can you provide a (the most?) simpler and complete example using egui?
Another option could be a basic tutorial? I didn't found one on the web.
Thanks anyway, the actual egui example is very convincing!
