nix-index VS nixos-config

nix-index can be used to provide this functionality, and to automate this process you can use nix-index-database (setup instructions are in the README).

Are you using flakes? AFAIK `command-not-found` does not work with them. See https://github.com/NixOS/nixpkgs/issues/171054 and https://discourse.nixos.org/t/why-isnt-there-an-official-bui...

I think `nix-index` works as a replacement: https://github.com/bennofs/nix-index

If you are on another distro or mac os there is also nix-index

nix-index is another option for searching for pkgs. You can search by name, or by specific files within a pkg.

You can use nix-locate from https://github.com/bennofs/nix-index to find files on NixOS:

nix-index makes it trivial to find which package contains a given file.

There are two ways I know of: - If you use old-school channels, there's an index in the channel. In particular, the command-not-found hook is able to use that. In this particular case, you would have to guess that git will look for the git-clang-tools, and command-not-found that. This looks like it only works for programs, not arbitrary files. - In any case, you can use the more general nix-index. That's what I did because I use flakes.

I use nix-index a lot to find which derivation a file belongs to, but building the index takes a while and so I end up not updating it very frequently.

Look at the library missing say X Use nix-locate to find the derivation that includes libX.dylib file (if it can’t find the macOS dylib version of the file try using the same name for linux by changing dylib for so) Add the derivation to you environmental and try again It will find the next missing library on the next compile.

I’ve been using Nix directly on MacOS with minimal issues for a few years now. Works great.

I hate using docker on Mac and have since replaced it with flakes and devenv.

I tried to make Nix as easy to adopt as possible by creating Nix commands and a step by step guide: https://github.com/dustinlyons/nixos-config

I love Nix. I use it every day to manage multiple local dev environments. And I use devenv instead of docker for sharing project-specific environments with others.

Felt (still am, actually) this problem too. Started with the same approach (Vanilla Emacs) a few years back in order to really learn the ins-and-outs after giving DOOM and others a shot and feeling like I didn't have the faintest what was really going on with all the magic. I somehow did end up falling in love with Emacs again[^1].

Won't lie... there was a fair amount of cursing involved and, despite the love, I wouldn't recommend many to venture down this road[^2].

Now I have gone the literate config way in my dotfiles https://github.com/vidbina/dotfiles/tree/main/emacs and I jump between Cursor (vscode-based), Neovim and Emacs for different tasks on a daily. I also found dustinlyons/nixos-config (https://github.com/dustinlyons/nixos-config/blob/main/module...) just a few days ago and figured that could be a fun resource when you're building yours up.

Take it as a hobby. There are a bunch of nice things that I picked up from Emacs (a. literate configs, b. comfort around working with LISPs, c. bigger appreciation for parts of the GNU ecosystem, d. more in-depth understanding of how my editor works which helps me debug issues in Neovim or vscode when I see them) but I still think that I'm cursed by wanting to go down this road so badly. Wish I could just vscode my way through live and build dope stuff, unencumbered.

1: Used Emacs heavily in college over 12 years ago when I would boot the Windows + Novell groupware school computers into my own Ubuntu config with my Emacs and embedded dev toolchain from my pendrive.

2: The single-threaded-ness and related ocassional unresponsiveness/hangups still grind my gears.

Here is my flake using home manager on Mac: https://github.com/dustinlyons/nixos-config

What do I need to do to switch from an official Nix install to using nix-installer on macOS? Just uninstall the current nix and install using nix-installer?

My config is loosely based off https://github.com/dustinlyons/nixos-config if this matters. Using nix-darwin.

My configuration uses Nix.

Not my personal notes, but how I do my writing and organize my thoughts. This is my Nix configuration that powers my Macbook, Linux PC, and home lab server. Emacs + org-roam to capture everything. https://github.com/dustinlyons/nixos-config
