Today, let's have a look at the Nix programming language.
|
|

|

Yesterday, I wrote about [Nix the package manager][0].
|
|
|
|
To use it, you need to write code in the Nix language in .nix files.
|
|
|
|
To see an example, you can see [my dotfiles on GitHub][1] as well as lots of other people's that they've published.
|
|
|
|
It's a functional language so some of the concepts were new to me, but I picked it up fairly quickly and learned some of the paradigms and conventions.
|
|
|
|
This is the code that installs Nginx on my server:
|
|
|
|
```nix
|
|
services.nginx = {
|
|
enable = true;
|
|
serverNamesHashBucketSize = 256;
|
|
};
|
|
```
|
|
|
|
These are some of the packages I have installed on my laptop:
|
|
|
|
```nix
|
|
environment.systemPackages = with pkgs: {
|
|
devenv
|
|
dog
|
|
git
|
|
go
|
|
jq
|
|
php
|
|
phpPackages.composer
|
|
pv
|
|
tldr
|
|
}
|
|
```
|
|
|
|
And this is how to configure processes [in a devenv configuration][2], which is built with Nix:
|
|
|
|
```nix
|
|
processes = {
|
|
tailwind.exec = ''
|
|
cd ${drupal.theme.path}
|
|
watchexec --exts css,twig tailwindcss --config assets/tailwind.config.ts \
|
|
--output dist/tailwind.css
|
|
'';
|
|
};
|
|
```
|
|
|
|
Once you have written the configuration, you can run it and install what you've specified, and it will do it the same way every time.
|
|
|
|
For a crash course in the Nix language, take a look at <https://zero-to-nix.com/concepts/nix-language> or one of the many open-sourced configurations on GitHub.
