# eframe template
## egui file browser (using poll-promise)

[![dependency status](https://deps.rs/repo/github/emilk/eframe_template/status.svg)](https://deps.rs/repo/github/emilk/eframe_template)
[![Build Status](https://github.com/emilk/eframe_template/workflows/CI/badge.svg)](https://github.com/emilk/eframe_template/actions?workflow=CI)
This example is based on the [original egui file browser](https://github.com/woelper/egui_pick_file) by [woelper](https://github.com/woelper) but modified to use poll-promise instead.
It makes the app a bit more complex but closer to what I personally prefer to use as it prevents the user from clicking load or save while the picker is still open.

This is a template repo for [eframe](https://github.com/emilk/egui/tree/master/crates/eframe), a framework for writing apps using [egui](https://github.com/emilk/egui/).
> Example app showing how to pick a file on both web and desktop.
The goal is for this to be the simplest way to get started writing a GUI app in Rust.
The web application can be accessed here:

You can compile your app natively or for the web, and share it using Github Pages.
https://c-git.github.io/egui_file_picker_poll_promise/

## Getting started
The web application for the original can be found at:

Start by clicking "Use this template" at https://github.com/emilk/eframe_template/ or follow [these instructions](https://docs.github.com/en/free-pro-team@latest/github/creating-cloning-and-archiving-repositories/creating-a-repository-from-a-template).
https://woelper.github.io/egui_pick_file/

Change the name of the crate: Chose a good name for your project, and change the name to it in:
* `Cargo.toml`
* Change the `package.name` from `eframe_template` to `your_crate`.
* Change the `package.authors`
* `main.rs`
* Change `eframe_template::TemplateApp` to `your_crate::TemplateApp`
* `index.html`
* Change the `<title>eframe template</title>` to `<title>your_crate</title>`. optional.
* `assets/sw.js`
* Change the `'./eframe_template.js'` to `./your_crate.js` (in `filesToCache` array)
* Change the `'./eframe_template_bg.wasm'` to `./your_crate_bg.wasm` (in `filesToCache` array)
For native:

### Learning about egui
`cargo run`

`src/app.rs` contains a simple example app. This is just to give some inspiration - most of it can be removed if you like.
For web:

The official egui docs are at <https://docs.rs/egui>. If you prefer watching a video introduction, check out <https://www.youtube.com/watch?v=NtUkr_z7l84>. For inspiration, check out the [the egui web demo](https://emilk.github.io/egui/index.html) and follow the links in it to its source code.
`rustup target add wasm32-unknown-unknown`

### Testing locally
`cargo install --locked trunk`

Make sure you are using the latest version of stable rust by running `rustup update`.
`trunk serve --open`

`cargo run --release`
## License

On Linux you need to first run:
All code in this repository is dual-licensed under either:

`sudo apt-get install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libxkbcommon-dev libssl-dev`
- Apache License, Version 2.0
- MIT license

On Fedora Rawhide you need to run:
at your option.
This means you can select the license you prefer!
This dual-licensing approach is the de-facto standard in the Rust ecosystem and there are very good reasons to include both as noted in
this [issue](https://github.com/bevyengine/bevy/issues/2373) on [Bevy](https://bevyengine.org)'s repo.

`dnf install clang clang-devel clang-tools-extra libxkbcommon-devel pkg-config openssl-devel libxcb-devel gtk3-devel atk fontconfig-devel`
### Contribution

### Web Locally

You can compile your app to [WASM](https://en.wikipedia.org/wiki/WebAssembly) and publish it as a web page.

We use [Trunk](https://trunkrs.dev/) to build for web target.
1. Install the required target with `rustup target add wasm32-unknown-unknown`.
2. Install Trunk with `cargo install --locked trunk`.
3. Run `trunk serve` to build and serve on `http://127.0.0.1:8080`. Trunk will rebuild automatically if you edit the project.
4. Open `http://127.0.0.1:8080/index.html#dev` in a browser. See the warning below.

> `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.
### Web Deploy
1. Just run `trunk build --release`.
2. It will generate a `dist` directory as a "static html" website
3. Upload the `dist` directory to any of the numerous free hosting websites including [GitHub Pages](https://docs.github.com/en/free-pro-team@latest/github/working-with-github-pages/configuring-a-publishing-source-for-your-github-pages-site).
4. we already provide a workflow that auto-deploys our app to GitHub pages if you enable it.
> To enable Github Pages, you need to go to Repository -> Settings -> Pages -> Source -> set to `gh-pages` branch and `/` (root).
>
> If `gh-pages` is not available in `Source`, just create and push a branch called `gh-pages` and it should be available.
You can test the template app at <https://emilk.github.io/eframe_template/>.

## Updating egui

As of 2023, egui is in active development with frequent releases with breaking changes. [eframe_template](https://github.com/emilk/eframe_template/) will be updated in lock-step to always use the latest version of egui.

When updating `egui` and `eframe` it is recommended you do so one version at the time, and read about the changes in [the egui changelog](https://github.com/emilk/egui/blob/master/CHANGELOG.md) and [eframe changelog](https://github.com/emilk/egui/blob/master/crates/eframe/CHANGELOG.md).
Unless you explicitly state otherwise, any contribution intentionally submitted
for inclusion in the work by you, as defined in the Apache-2.0 license, shall
be dual licensed as above, without any additional terms or conditions.
