Introduction

Ion is a modern system shell that features a simple, yet powerful, syntax. It is written entirely in Rust, which greatly increases the overall quality and security of the shell. It also offers a level of performance that exceeds that of Dash, when taking advantage of Ion's features. While it is developed alongside, and primarily for, RedoxOS, it is a fully capable on other *nix platforms.

Ion Shell

MIT licensed crates.io Documentation

Ion is still a WIP, and both its syntax and rules are subject to change over time. It is still quite a ways from becoming stabilized, but we are getting very close. Changes to the syntax at this time are likely to be minimal.

Ion Specification

Ion has a RFC process for language proposals. Ion's formal specification is located within the rfcs branch. The RFC process is still in the early stages of development, so much of the current and future implementation ideas have yet to be written into the specification.

Ion Manual

The Ion manual online is generated automatically on each commit via mdBook and hosted on Redox OS's website.

Building the manual for local reference

Sources for the manual are located in the manual directory.

  1. Build the documentation file for the builtins
make manual
  1. Then build the rest of the Ion manual via mdbook
mdbook build manual

Or you can build and open it in the your default browser via

mdbook serve manual --open

Or you can build and host the manual on your localhost via

mdbook serve manual 

Ion library example

See the examples folder and the Parallelion project

Packages

Pop!_OS / Ubuntu

The following PPA supports the 18.04 (bionic) and 19.04 (disco) releases. Bionic builds were made using the Pop_OS PPA's rustc 1.39.0 package.

sudo add-apt-repository ppa:mmstick76/ion-shell

Developer set up

Those who are developing software with Rust should install the Rustup toolchain manager. After installing rustup, run rustup override set 1.56.0 to set your Rust toolchain to the version that Ion is targeting at the moment. To build for Redox OS, rustup override set nightly is required to build the Redox dependencies.

Build dependencies

Please ensure that both cargo and rustc 1.56.0 or higher is installed for your system. Release tarballs have not been made yet due to Ion being incomplete in a few remaining areas.

Installation

Installation of Ion shell for one user

git clone https://gitlab.redox-os.org/redox-os/ion/

# Install to path which is included in the $PATH enviromnent variable
DESTDIR=~/.local/bin bash/install.sh

Installation of Ion shell system wide, for all users

git clone https://gitlab.redox-os.org/redox-os/ion/
cd ion
cargo build --release 
sudo DESTDIR=/usr/local/bin bash/install.sh
# Optional: Do this if Ion shell shoulb be login shell on your system
sudo make update-shells prefix=/usr
