devenv VS doomemacs

I gave devenv multiple tries, and I am sorry to say there are multiple annoying issues that forced me to give up every time.

Some of these 200+ issues are unsolved for a fairly long time.

Software developers often want to customize:

1. their home environments: for packages (some reach for brew on MacOS) and configurations (dotfiles, and some reach for stow).

2. their development shells: for build dependencies (compilers, SDKs, libraries), tools (LSP, linters, formatters, debuggers), and services (runtime, database). Some reach for devcontainers here.

3. or even their operating systems: for development, for CI, for deployment, or for personal use.

Nix provision all of the above in the same language, with Nixpkgs, NixOS, home-manager, and devShells such as https://devenv.sh/. What's more, Nix is (https://nixos.org/):

- reproducible: what works on your dev machine also works in CI in prod,

- declarative: you version control and review your configurations and infrastructure as code, at a reasonable level of abstraction,

- reliable: all changes are atomic with easy roll back.

https://devenv.sh/ and nix in general are great for setting up dev environments.

> but worried that the development is not moving forward

There is an open v1.0 PR: https://github.com/cachix/devenv/pull/1005

2) A way to run services apps depend on (databases, job runners, cache etc).

I am going to suggest one of the Nix based tools that do those things:

  - https://devenv.sh/ (I use this at work)

Yup, I haven’t tried it but there is https://devenv.sh which is built on top of nix and makes it simple.

Although Guix reads better than Nix (after all, it's Lisp), I found the support and resources available for learning severely lacking.

Plus, you have to jump through hoops to install non-free software, which goes against the ethos of Guix anyway.

IMHO, Nix is clearly "the winner" here and we'll see more and more adoption as it improves. Lots of folks are doing exciting work (see https://determinate.systems/, https://devenv.sh/, https://flakehub.com/). And the scale and organization around nixpkgs is damn impressive.

I don't think you can ever get Nix as simple as PNPM, simply because native libraries are sometimes annoying, need to be configured at build time to a greater degree and because the problem space it attacks is so much larger than PNPM, which only deals with the JS/Node.js ecosystem.

However, I do think that there exist reasonable levels of abstraction that sacrifice some expressive power for simplicity and such systems could maybe expose a PNPM-like CLI. One example that comes to mind is devenv.nix [1]. While it doesn't yet have a CLI, its configuration file is YAML and relatively simple. I think there's more to be done in this space and I hope for tools that are easier to grasp in the future.

> Nix package files evaluate down to configuration for the Nix package manager, but I haven’t ever seen a good explanation for the basic essentials underneath all the abstraction. Every guide I’ve learned from and all the package defs I’ve read seem to cargo cult many layers of mysterious config composing config. Without easy to learn essentials it’s difficult to grok the system as a whole.

To me it sounds like the essential that you're referring to is the 'derivation' primitive, which is almost always hidden behind the mkDerivation abstraction from nixpkgs. This [2] blog post is an exploration of what exactly that means.

I'd also love for the documentation situation to be much better, in particular in terms of official, curated resources. But I'm not convinced that you actually need to know the difference between derivation and mkDerivation to make effective use of Nix, because in practice you would always use the latter. That said, mkDerivation and the whole of nixpkgs is essentially a huge DSL (I believe this is what you meant when you said 'config composing config') that you do need to know and is woefully underdocumented.

> I would love to adopt Nix for developer tooling for Notion’s engineers, but today it’s about infinity times easier to work around the limitations mentioned of Docker+Ubuntu+NPM than to work around the limitations of Nix.

One approach I have taken to is to specify the environment in Nix, but then generate Docker devcontainers from it, so most people don't come into contact with Nix if they don't want to.

This though, through the use of devenv.sh, which uses nix, as when I got into nix I though it was going to be easier to just make a development environment, not the case. Until I found devenv.sh, I could actually finally make good environments... It also has other features like containers and services, which also help me know that I can get the most of it if the time comes.

Yes, you need to install Emacs. It is probably available from whatever package manager your system uses.

I prefer Doom (https://github.com/doomemacs/doomemacs) to Spacemacs. However I haven't looked at Spacemacs for many years; perhaps it's now on par with Doom.

Ever since I've started my Emacs journey it seemed like the wholy grail to have your own (vanilla!) configuration without any hard dependencies on frameworks like Doom or Spacemacs. There are plenty of dotemacs configurations ouf there which can serve as a great source of inspiration.

Use doomemacs for a start. It really optimizes startup time and offers vast included modules as well as great package management. https://github.com/doomemacs/doomemacs/blob/master/docs/gett...

I installed Corfu using this PR in doom https://github.com/doomemacs/doomemacs/pull/7002

The doom documentation does a pretty good job of walking you through this: - https://github.com/doomemacs/doomemacs/blob/master/docs/getting_started.org - https://noelwelsh.com/posts/doom-emacs/

I was poking around and opened up the README.org file in the Doom Emac's faust module and i saw these nifty nagivation things that weren't coming form within the file. I didn't see anything in the directory that hinted at it (to me) either.

I tried this code: $ git clone --depth 1 https://github.com/doomemacs/doomemacs ~/.config/emacs ~/.config/emacs/bin/doom install

I am a long-time Emacs user and used to maintain my own config, but I switched to Doom Emacs [1] a year ago. Doom Emacs is like a pre-packaged/pre-configured emacs distro. You still need to configure the features that you want to use, but it's a lot easier (and faster) than having to do everything from scratch, and definitely if you already have some emacs background anyway. For me, it makes the newer, more advanced, features more accessible. Since switching, I started to use Emacs more again.
