## Nix Virtual Machines
|
||||
|
||||
Several Nix virtual machine definitions are provided by the project for testing
|
||||
and developing Ghostty against multiple different Linux desktop environments.
|
||||
|
||||
Running these requires a working Nix installation, either Nix on your
|
||||
favorite Linux distribution, NixOS, or macOS with nix-darwin installed. Futher
|
||||
requirements for macOS are detailed below.
|
||||
|
||||
VMs should only be run on your local desktop and then powered off when not in
|
||||
use, which will discard any changes to the VM.
|
||||
|
||||
The VM definitions provide minimal software "out of the box" but additional
|
||||
software can be installed by using standard Nix mechanisms like `nix run nixpkgs#<package>`.
|
||||
|
||||
### Linux
|
||||
|
||||
1. Check out the Ghostty source and change to the directory.
|
||||
2. Run `nix run .#<vmtype>`. `<vmtype>` can be any of the VMs defined in the
|
||||
`nix/vm` directory (without the `.nix` suffix) excluding any file prefixed
|
||||
with `common`.
|
||||
3. The VM will build and then launch. Depending on the speed of your system, this
|
||||
can take a while, but eventually you should get a new VM window.
|
||||
4. The Ghostty source directory should be mounted to `/tmp/shared` in the VM. Depending
|
||||
on what UID and GID of the user that you launched the VM as, `/tmp/shared` _may_ be
|
||||
writable by the VM user, so be careful!
|
||||
|
||||
### macOS
|
||||
|
||||
1. To run the VMs on macOS you will need to enable the Linux builder in your `nix-darwin`
|
||||
config. This _should_ be as simple as adding `nix.linux-builder.enable=true` to your
|
||||
configuration and then rebuilding. See [this](https://nixcademy.com/posts/macos-linux-builder/)
|
||||
blog post for more information about the Linux builder and how to tune the performance.
|
||||
2. Once the Linux builder has been enabled, you should be able to follow the Linux instructions
|
||||
above to launch a VM.
|
||||
|
||||
### Contributing new VM definitions
|
||||
|
||||
#### Acceptance Criteria
|
||||
|
||||
We welcome the contribution of new VM definitions, as long as they meet the following criteria:
|
||||
|
||||
1. The should be different enough from existing VM definitions that they represent a distinct
|
||||
user (and developer) experience.
|
||||
2. There's a significant Ghostty user population that uses a similar environment.
|
||||
3. The VMs can be built using only packages from the current stable NixOS release.
|
||||
|
||||
#### VM Definition Criteria
|
||||
|
||||
1. VMs should be as minimal as possible so that they build and launch quickly.
|
||||
Additonal software can be added at runtime with a command like `nix run nixpkgs#<package name>`.
|
||||
2. VMs should not expose any services to the network, or run any remote access
|
||||
software like SSH, VNC or RDP.
|
||||
3. VMs should auto-login using the "ghostty" user.
