# Introduction
|
||||
|
||||
This project is under construction as a rewrite of my [legacy][old]
|
||||
NixOS configuration, using the [experimental][rfc] _flakes_ mechanism.
|
||||
NixOS configuration, using the experimental [flakes][rfc] mechanism.
|
||||
|
||||
|
||||
#### [Flake Talk][video]
|
||||
|
||||
# Usage
|
||||
Enter a nix-shell either manually or automatically using [direnv][direnv]. This
|
||||
will set up the exerimental nix features that need to be available to use
|
||||
[flakes][pr]. A basic `rebuild` command is included in the shell to replace
|
||||
`nixos-rebuild` for now.
|
||||
|
||||
|
||||
|
||||
## [setup][pr]:
|
||||
```nix
|
||||
{
|
||||
|
||||
nix.package = nixFlakes;
|
||||
|
||||
nix.extraOptions = ''
|
||||
experimental-features = nix-command flakes
|
||||
'';
|
||||
|
||||
}
|
||||
```
|
||||
Usage: rebuild [host] {switch|boot|test}
|
||||
```
|
||||
|
||||
### sans [NixOS][nixos]:
|
||||
```
|
||||
# nix-env -f '<nixpkgs>' -iA nixFlakes
|
||||
You can specify one of the host configurations from the [hosts](hosts)
|
||||
directory. If omitted, it will default to your systems current hostname.
|
||||
|
||||
# echo "experimental-features = nix-command flakes" >> /etc/nix/nix.conf
|
||||
In addtion:
|
||||
```
|
||||
rebuild iso
|
||||
```
|
||||
|
||||
Will make a minimal and bootable iso image of the [niximg](hosts/niximg.nix)
|
||||
configuration. You can customize the image by editing this file.
|
||||
|
||||
You can also install the packages declared in [pkgs](pkgs) without needing
|
||||
to install NixOS. For example:
|
||||
```
|
||||
# from top-level
|
||||
nix profile install ".#packages.x86_64-linux.purs"
|
||||
```
|
||||
|
||||
# Contributing
|
||||
|
||||
The purpose of this repository is to allow for simpler modularity and
|
||||
maintainability than was achieved in a previous effort. Flakes, along with a
|
||||
standardized structure, make this simple.
|
||||
|
||||
## Hosts
|
||||
Distributions for particular machines should be stored in the [hosts](hosts)
|
||||
directory. Every file in this directory will be added automatically to the
|
||||
available NixOS configurations available in the `nixosConfigurations` flake
|
||||
output. See the [`default.nix`](hosts/default.nix) for implementation details.
|
||||
|
||||
## Profiles
|
||||
More abstract configurations that can be reused by multiple machines should
|
||||
go in the [profiles](profiles) directory. It's structure is pretty straight
|
||||
forward. Just have a look to get an idea. Every profile should have a
|
||||
`default.nix` to easily import it. You can also stick things in the profile's
|
||||
subdirectory which are not automatically imported by its `default.nix` but are
|
||||
meant to be manually imported from a host (useful for less common, or
|
||||
specialized configurations).
|
||||
|
||||
In addition, profiles can depend on other profiles. For example, The
|
||||
[graphical](profiles/graphical) profile depends on [develop](profiles/develop)
|
||||
simply by importing it in its [`default.nix`](profiles/graphical/default.nix).
|
||||
|
||||
## Users
|
||||
User declaration belongs in the [users](users) directory. Everything related to
|
||||
your user should be declared here. For convenience, [home-manager][home-manager]
|
||||
is available automatically for home directory setup.
|
||||
|
||||
## Modules and Packages
|
||||
All [modules](modules/default.nix) and [pkgs](pkgs/default.nix) are available
|
||||
for every configuration automatically. Simply add a `*.nix` file to one of
|
||||
these directories declaring your module or package, and update the
|
||||
corresponding `default.nix` to point to it. Now you can use your new module or
|
||||
install your new package as usual.
|
||||
|
||||
Doing this will also add them to the flake's `nixosModules` or `overlays`
|
||||
outputs to import them easily into an external NixOS configuration as well.
|
||||
|
||||
## Pull Requests
|
||||
|
||||
If you'd like to add a package, module, profile or host configuration please
|
||||
be sure to format your code with [`nixpkgs-fmt`][nixpkgs-fmt] before
|
||||
opening a pull-request. The commit message follows the same semantics as
|
||||
[nixpkgs][nixpkgs]. You can use a `#` symbol to specify abiguities. For example,
|
||||
`develop#zsh: <rest of commit message>` would tell me that your updating the
|
||||
`zsh` configuration living under the `develop` profile.
