Ion - An Oxidized Electron

Proof of concept for building native html/css/rust apps using servo. Ideally, this would be like electron, but with rust/servo instead of javascript/webkit

Progress

This is one big massive hack, and will probably never be completed.

Structure

See app.rs for the meat of the application. You simply provide a render function that takes a state and produces an immutable dom tree. Everything else is library code that does not need to be duplicated.

To build: Download my fork of servo, https://github.com/justinmichaud/servo to ../servo On Mac, build as normal with cargo:

cargo run --release

On Fedora 27, I needed to use these env flags to get glutin to work. This seems to be some mesa bug, which should be fixed soon. Also, for some reason, on Fedora a release build crashes with SIGILL

RUST_BACKTRACE=full
WAYLAND_DISPLAY=wayland-1

TODO:

  • Find a way to not mutilate servo's encapsulation
  • Support embedding css with an element
  • Add an html template macro
  • Native file menu, open/save file dialog
  • OpenGL support: Allow overlaying opengl content, maybe hook into window.present callback? Canvas integration would be nice.

To upgrade servo: change cargo.toml, then cp -r ../servo/resources . && cp ../servo/Cargo.lock . && cp ../servo/rust-toolchain .
