Update wiki on various topics This update is too large, I made too many notes on stuff. Nonetheless, it is very nice to see progress. I've made note revisions on the following topics: - Learning - Writing - Various Linux-related stuff I've yet to start learning illustration but I'll be starting tomorrow for an update how do I keep in mind with those writings. There are still a lot of things to be processed from the backlog with yet more notes on learning but I keep having those perspectives whenever I practice so ehhh... Better have those than nothing? Furthermore, I've also updated the timestamp format. It is pretty simple to update all of the notes with a couple of `sed` calls. Aaaand, I've also changed the way how the assets stored with the folders only leaving it up for the generated files instead of enforcing it on every note. I create more visual aids and managing them is a pain for each note. This restructuring frees me of that burden.

A self-contained Nix module that takes inputs (can be from other flakes) and create outputs.
It is comparable to [[https://guix.gnu.org/manual/en/html_node/Channels.html][Guix channels]] (or the NUR) in the way any arbitrary value can be exported, thus extending a Nix module in any direction the author can make it to.
Also, it supercedes Nix channels as a way to manage your system.

- Since it is self-contained, it is easier to compose and develop environments for projects.
- It is more declarative compared to Nix channels.
- Provides a structure for discoverability through exploring the output.
- In case you're using roam:NixOS, it also provides an easier way to extend it with third-party custom modules.

* Exploring a Nix flake
To get started with a flake, you can quickly create one with =nix flake init=.
This will create =flake.nix= which is also required for Nix to recognize the project as a flake.
Here's the skeleton of a flake.
#+begin_src nix
{
description = "A basic flake.";
inputs = {};
outputs = {};
}
#+end_src
It is really just an attribute set that mainly deals with three attributes:
- =description= which is self-descriptive enough to see what's it for. ;p
- =inputs= which contains inputs (that are other flakes) to be used for...
Update the notebook Not all changes are here though.
2022-01-09 04:24:55 +00:00
- ...the =outputs= which is a set or a function that returns an attribute set to be exported.

2021-12-28 13:13:35 +00:00
Here's a real example of a basic flake.
#+begin_src nix
{
description = "A basic flake with some real inputs this time.";
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs";
home-manager.url = "github:nix-community/home-manager";
home-manager.inputs.nixpkgs.follows = "nixpkgs";
};
outputs = attrs@{ self, nixpkgs, home-manager, ... }: {
homeManagerConfiguration = import ./hmUsers;
packages.x86_64-linux = {
hello = nixpkgs.pkgs.hello;
};
};
}

2021-12-28 13:13:35 +00:00
The flake requires other flakes from the nixpkgs and home-manager as indicated from the URL.
This will get the latest revision of both inputs.
This is not ideal as it will get the latest revisions every time it requests the inputs.
While you can pin the version by adding more information (e.g., =nixpkgs.url = "github:NixOS/nixpkgs/nixos-21.11"=, =home-manager.url = "github:nix-community/home-manager/781d25b315def05cd7ede3765226c54216f0b1fe"=), this isn't really necessary for the most part as we have lockfiles to secure our dependencies version.
These lockfiles can be found at =flake.lock= where complete metadata for the flakes are found.
* Selected list of attributes for outputs
While you can export attributes of any type, there are common attributes you'll mostly see.
As an example, here's the flake of my NixOS configuration.
#+begin_src shell :cache yes :results output
nix flake show github:foo-dogsquared/nixos-config | nix run nixpkgs#gnused -- 's/\x1b\[[0-9;]*m//g'

- =defaultPackage.${system}.${package}= (or =packages.${system}.${package}=) is mainly expected for packages.
This allows for easy building — e.g., =nix build nixpkgs#hello= will refer to =defaultPackage.${system}.hello=.
Another command that expects this is =nix run ${PACKAGE}= (e.g., =nix run nixpkgs#hello=).

- =nixosConfigurations.${host}= is a NixOS host configuration.
Each attribute contain a set similar to the traditional set from =/etc/nixos/configuration.nix=.
This is very beneficial for quickly installing only with flakes — e.g., =nixos-install --flake github:foo-dogsquared/nixos-config#zilch= will install with =nixosConfigurations.zilch=.
However, attributes should be created with =lib.nixosSystem= from =nixpkgs= flake.

I create more visual aids and managing them is a pain for each note. This restructuring frees me of that burden.

- =nixosModules.${module}= is a [[roam:NixOS modules]], allowing you to extend NixOS further.
These are expected to be similar NixOS modules from nixpkgs.
- =templates.${name}= is a template that has the attribute =path= and =description=.
See [[Flake templates]] for more details about how it's used.
- =devShell.${system}= is expected to be a derivation (mostly with =mkShell=).
This is the default development environment to be used.
This is mostly expected for projects providing an easy way to bootstrap for development (e.g., with =nix develop ${FLAKE}=).

- =devShells.${system}.${name}= is an attribute set of derivations (mostly from =mkShell=).
This is similar to =devShell= except this is where =nix develop= subcommand finds if an attribute name is given.

* Flake templates
- Flakes can have templates to get started with.
They can be used with =nix flake init ${TEMPLATE}=.
- You can export it in your flakes through the =templates= attribute.
=templates= is expected to be an attribute set with each attribute representing a template.
- By default, we have the =templates= flake from the global registry pointed to [[https://github.com/NixOS/templates][NixOS/templates]] Git repo.
* Nix registry
Per the Nix manual:
#+begin_quote
Flake registries are a convenience feature that allows you to refer to flakes using symbolic identifiers such as =nixpkgs=, rather than full URLs such as =git://github.com/NixOS/nixpkgs=.
#+end_quote
Here's an example of the registry list with some overriden flakes such as the =nixpkgs= flake following from my [[https://github.com/foo-dogsquared/nixos-config][NixOS configuration]].
#+begin_src shell :cache yes

So how does a flake registry work?
- It is managed through =nix registry= subcommand or set =nix.registry= in your system configuration.
- Registries are primarily written as JSON files in certain files (e.g., =$XDG_CONFIG_HOME/nix/registry=, =/etc/nix/registry.json=).
For more information, see the [[https://nixos.org/manual/nix/stable/command-ref/new-cli/nix3-registry.html#registry-format][registry format from the manual]].
Unlike the traditional Nix channels, the inclusion of arbitrary files and their locations doesn't seem to affect the reproducibility since it is mostly used as a convenience feature after all.
- The flakes from default registry are mostly getting the latest revisions of the flake per invocation so it is best practice to pin them (e.g., =nix registry pin=, through =nix.registry= while setting the NixOS systems in =flake.nix=).
- There are primarily three registries to worry about: user, system, and global.
- This is also the reason it downloads something why each time you invoke a Nix-related command (e.g., =nix search=, =nix edit=).
[fn:: I think pinning the flakes from the global registry will simply resolve this issue.]

- We can modify our inputs.
In the above example, we made =home-manager= to use our version of =nixpkgs= which will make it easier to sync.
