In this article I'll explain how I use nix.
|
||||
I don't use NixOS nor any Linux as my main desktop environment[fn:desktop].
|
||||
Still I use [[https://nixos.org/nix][nix]] on a few mac computers.
|
||||
It has multiple usages.
|
||||
Have you ever written a small script and you update your system and this
|
||||
stop working?
|
||||
Have you copied your tool/script to another machine it doesn't work because
|
||||
some dependency is missing?
|
||||
Have you tried to sync your dotfiles to another env and there are a few
|
||||
details not working? Some missing dependency?
|
||||
If the answer is yes, then [[https://nixos.org/nix][nix]] can help.
|
||||
|
||||
First, let's start by the bad news.
|
||||
Recent macOS security policy made nix a bit harder to install on a mac.
|
||||
See [[https://hydra.nixos.org/build/119559243/download/1/manual/#sect-macos-installation][macOS Installation instructions]].
|
||||
** Scripts
|
||||
:PROPERTIES:
|
||||
:CUSTOM_ID: scripts
|
||||
:END:
|
||||
|
||||
Once you have nix installed you should update the nix-channel.
|
||||
Mainly a nix-channels is where are the definitions of all the packages.
|
||||
See [[https://hydra.nixos.org/build/119559243/download/1/manual/#sec-channels][nixOS documentation]].
|
||||
Suppose you want to write a portable script.
|
||||
For example, the script I use to minify my CSS.
|
||||
Here it is:
|
||||
|
||||
#+begin_src shell
|
||||
#!/usr/bin/env nix-shell
|
||||
#!nix-shell --pure
|
||||
#!nix-shell -i bash
|
||||
#!nix-shell -I nixpkgs="https://github.com/NixOS/nixpkgs/archive/19.09.tar.gz"
|
||||
#!nix-shell -p bash minify
|
||||
|
||||
minify "$1" > "$2"
|
||||
#+end_src
|
||||
|
||||
So let's analyze each line of the header block:
|
||||
|
||||
- ~#!/usr/bin/env nix-shell~ :: basic, use ~nix-shell~ to run the script.
|
||||
- ~#!nix-shell --pure~ :: only use dependencies installed in this nix shell
|
||||
environment. A bit as if the PATH environment variable was emptied.
|
||||
- ~#!nix-shell -i bash~ :: tell ~nix-shell~ to run ~bash~
|
||||
- ~#!nix-shell -I nixpkgs="https://github.com/NixOS/nixpkgs/archive/19.09.tar.gz"~ ::
|
||||
pin the nixpkgs using this archive.
|
||||
- ~#!nix-shell -p bash minify~ :: install ~bash~ and ~minify~ in the nix shell.
|
||||
|
||||
Now if the script is run on a machine with ~nix~ installed you can be
|
||||
pretty sure it will work as expected.
|
||||
Even if I update my OS and I forget about this script for a few years.
|
||||
As long as I can install nix on the new system and I could download the tar
|
||||
file the script will be run the same way as the day I wrote it.
|
||||
|
||||
** Temporary working env
|
||||
:PROPERTIES:
|
||||
:CUSTOM_ID: temporary-working-env
|
||||
:END:
|
||||
|
||||
Quite often, I need to do something, and run a specific command that need
|
||||
me to install a very specific command.
|
||||
And I'm pretty sure I will not use this tool ever again.
|
||||
|
||||
For those cases, what I do, is generally run my command directly with a
|
||||
fresh ~nix-shell~.
|
||||
|
||||
#+begin_src shell
|
||||
> nix-shell -p httpie
|
||||
[nix-shell:~]$ ... here I can use httpie ...
|
||||
#+end_src
|
||||
|
||||
** Home Manager
|
||||
:PROPERTIES:
|
||||
:CUSTOM_ID: home-manager
|
||||
:END:
|
||||
|
||||
First, I use [[https://github.com/rycee/home-manager][home-manager]], it's first usage it to list a reproductible list
|
||||
of application I need on all my desktop environments.
|
||||
So i edit the file =~/.config/nixpkgs/home.nix=.
|
||||
I provide a list of packages I want to have when I start a new shell.
|
||||
A few years ago I used =brew= to install the tools I need.
|
||||
With =nix= you can install a new tool with ~nix-env -i~ instead of ~brew install~.
|
||||
Still recently I prefer to use [[https://github.com/rycee/home-manager][home-manager]].
|
||||
|
||||
The main advantage is that it is even more reproductible and can easily be
|
||||
shared accross different machines.
|
||||
|
||||
Mainly when I need a new binary I add it in a description list in the file
|
||||
=~/.config/nixpkgs/home.nix=.
|
||||
It looks like this:
|
||||
|
||||
#+begin_src nix
|
||||
home.packages = with pkgs; [
|
||||

First ~rel20~ pin a nixpkgs some specific commit of nix packages.
|
||||
Second, I overriden the default packages of the =weechat= package.

Another interresting one is this block:

I use macOS so even though I'm using a darwin focused nixpkgs

sometimes a few package can be broken and can't be installed.
|

|
||||
|
||||
That occurred with [[https://hackage.haskell.org/package/sws][=sws=]] during the upgrade to 20.03 on darwin.
|

This is a simple tool that need haskell to be compiled locally and

So it means I want to install =ghc= the main Haskell compiler.
|
||||
But also with some specific haskell packages.
|
||||
The interresting part, is that in most classical OS environment if you want
|
||||
a package from a specific language platform.
|
||||
You need to install the package manager for this language (npm, pip,
|
||||
etc...).
|
||||
And in =nixpkgs= there are formulae for most of these language specific
|
||||
packages.
|
||||
So instead of just installing =cabal-install= and then installing the
|
||||
packages I need.
|
||||
Which could also go bad, because they might be upgraded and not be
|
||||
compatible all at the same time.
|
||||
|
||||
I used nix to install the packages I needed.
|
||||
And one interresting detail.
|
||||
One package [[https://hackage.haskell.org/package/sws][=sws=]] is broken in 20.03 on darwin.
|
||||
So I used the older version from 19.09.
|
||||
|
||||
[fn:desktop]: I'm using macOS, and I have multiple macs.
|
||||
A laptop and two desktop machines.
|
||||
Using the 27" iMac is my ultimate work station.

Using the 27″ iMac is my ultimate work station.
|
||||
It really enhance my productivity.
|
||||
Still the laptop is a superior work environment for more casual tasks.
|
||||
I guess I might write someday about my full work environment.

|

First, let's start by the bad news.
|
||||
Recent macOS security policy made nix a bit harder to install on a mac.
|
||||
See [[https://hydra.nixos.org/build/119559243/download/1/manual/#sect-macos-installation][macOS Installation instructions]].
|
||||
|
||||
Once you have nix installed you should update the nix-channel.
|
||||
Mainly a nix-channels is where are the definitions of all the packages.
|
||||
See [[https://hydra.nixos.org/build/119559243/download/1/manual/#sec-channels][nixOS documentation]].
