Building exa from source
exa is open-source, and you can build your own version if you want.
If you’re interested in contributing to exa’s development or adding features, then the Vagrant development environment might make things easier for you.
exa is written in Rust, so before you do anything else, you’ll need to get a Rust compiler installed.
The easiest way to get started with Rust is to install Rustup, which can download and install Rust, the Cargo package manager and build tool, and manage updates to both components. There’s a shell command to install it, as well as other installation methods.
Installing other dependencies
Your OS’s package manager will almost certainly provide packages for both of these.
If you can’t install them, though, you can opt out of exa’s Git functionality by passing
--no-default-features to the Cargo commands below.
Once you’ve got the code and set up your environment, you can use Cargo to build exa:
And a runnable binary will appear in the
You can “install” exa permanently by copying this binary to a directory inside your
--release flag tells Rust to build the binary with more optimisations and less debugging information, which is usually what you want if you’re not trying to develop exa.
