## 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. Further
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` or `create`.
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.
### Custom VMs
To easily create a custom VM without modifying the Ghostty source, create a new
directory, then create a file called `flake.nix` with the following text in the
new directory.
```
{
inputs = {
nixpkgs.url = "nixpkgs/nixpkgs-unstable";
ghostty.url = "github:ghostty-org/ghostty";
};
outputs = {
nixpkgs,
ghostty,
...
}: {
nixosConfigurations.custom-vm = ghostty.create-gnome-vm {
nixpkgs = nixpkgs;
system = "x86_64-linux";
overlay = ghostty.overlays.releasefast;
# module = ./configuration.nix # also works
module = {pkgs, ...}: {
environment.systemPackages = [
pkgs.btop
];
};
};
};
}
```
The custom VM can then be run with a command like this:
```
nix run .#nixosConfigurations.custom-vm.config.system.build.vm
```
A file named `ghostty.qcow2` will be created that is used to persist any changes
made in the VM. To "reset" the VM to default delete the file and it will be
recreated the next time you run the VM.
### Contributing new VM definitions
#### VM 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.
Additional 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 daemons, VNC or RDP.
3. VMs should auto-login using the "ghostty" user.

# Subcommand Actions
This is the cli specific code. It contains cli actions and tui definitions and
argument parsing.
This README is meant as developer documentation and not as user documentation.
For user documentation, see the main README or [ghostty.org](https://ghostty.org/docs).
## Updating documentation
Each cli action is defined in it's own file. Documentation for each action is defined
in the doc comment associated with the `run` function. For example the `run` function
in `list_keybinds.zig` contains the help text for `ghostty +list-keybinds`.
