Control Web Applications

Simple web apps to demonstrate basic control theory. Try it here.

Development

The app is written in Rust using egui and eframe. It is based on the eframe_template.

Compilation - WASM

Trunk is used to compile the rust code to Wasm and then package the necessary HTML and JavaScript wrappers into a complete webpage. Trunk can be intalled via cargo, i.e., cargo install --locked trunk. Make sure the wasm32-unknown-unknown target for rustc is installed, if you are using rustup this can be done with rustup target add wasm32-unknown-unknown.

  • trunk serve will serve the webpage on 127.0.0.1:8080 and automatically rebuild if any files are changed.
  • trunk build --release will build a release version of the webpage into the dist directory.

Note, the JS wrapper is set up to cache the Wasm app which cause problem when developing. The caching can be bypassed by requesting the index.html#dev page.

Compilation - Local

The eframe framework also supports being compiled down to an ordinary desktop app. This can be done via normal cargo commands, e.g., cargo run, cargo build --release etc.

However, on Linux you need to first run:

sudo apt-get install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev libspeechd-dev libxkbcommon-dev libssl-dev

On Fedora Rawhide you need to run:

dnf install clang clang-devel clang-tools-extra speech-dispatcher-devel libxkbcommon-devel pkg-config openssl-devel libxcb-devel fontconfig-devel
