The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Emacs Advent Calendar 9: devdocs, code-cells, dREPL, etc.
buffer-env: A pure-Elisp version of the direnv utility. Useful to make Emacs aware of Python virtualenvs (which, judging by the questions posted here, is unfortunately still a complication for a lot of people). Similar to (and inspired by) envrc, but doesn't require the direnv program.

Nix Survival Mode: macOS upgrades won't break Nix anymore
Yes, most Nix users employ https://direnv.net or the equivalent for your IDE of choice. Emacs for instance has https://github.com/purcell/envrc which set per-buffer variables.

Beginner question: how do I set up virtual environments in my Python buffer?
Also take a look at the envrc package. I think it handles multiple projects better.

How do YOU use your PKMS?
I further make my software projects so that when I click a link I go into an environment pre-loaded with their dependencies so dropping in/out of projects is always frictionless. I do this with the reproducibility guarantees of nix, along with glue like nix-direnv and envrc-mode to direnv.

Minimal approach for python devel environment with flake
In conjunction with installing direnv on your favorite text editor, it's a very hassle free experience. Everything happens automatically. If you use Emacs, i higly recommend envrc.el

Nix and envrc
Direnv is installed using the nix-direnv installation instructions under "Via configuration.nix in NixOS". I read some recommendations that envrc.el is a better alternative then direnv.el, and after some testing I have to agree. (envrc-global-mode) is enabled in my config. This works perfectly with a normal emacs instance.

Emacs + emacs-direnv + Nix + vterm does not just work
I don't use flake.nix, only shell.nix, though check if the envrc package works any better for you. https://github.com/purcell/envrc
-
Wrapping gcc with libraries
As an alternative to emacs-direnv, I’d recommend the “envrc” package.
-
Eglot appreciation post
btw, my main issue regarding tramp was the fact that I didn't have my environment generated by direnv, via the https://github.com/purcell/envrc package. I use direnv almost exclusively to activate my nix-shell, so I can access the exact software dependencies required by that directory of a project.
-
Is it possible to let overlay Emacs use locally configured Agda libraries inside nix-shell?
I'm not familiar with these tools too but I highly recommend to look at https://github.com/purcell/envrc. If you are not familiar with direnv I suggest to try it with nix-shell/flakes before.

flox – Harness the Power of Nix
(I'm on the flox team) we'd love to support that and it's something we've talked about! We already support auto-generation for some languages like Rust because they have a lockfile (e.g. Cargo.lock), but it's a bit trickier for a requirements.txt. We hope at some point to contribute to/integrate with upstream efforts like dream2nix which have auto-generation as their goal

How about dream2nix? I like to use the nix way, but there are many third nix ways

yarnpnp2nix: More efficient way of packaging NodeJS applications
I'm not 100% sure, but looking at the docs [here](https://nix-community.github.io/dream2nix/subsystems/node.html#granular-pure-default) and the implementation [here](https://github.com/nix-community/dream2nix/tree/main/src/subsystems/nodejs/builders/granular-nodejs) it seems as it builds dependencies separately and symlinks (see `install-deps.py` those into a `node_modules` tree. I don't know much about Yarn's PNP (was doing more backend/devex last few years), but it sounds vaguely similar in that each package should be built once as a separate derivation and then symlinked to a big `node_modules`-as-a-symlink-tree derivation?

How do you build NodeJS project in Nix? 2022
How are you building your NodeJS project with Nix right now? Recently I spot a new abstraction, it looks good but I havn't tried it yet: https://github.com/nix-community/dream2nix

dream2nix - include a test run? (node project)
dream2nix is a great package, that makes a nix-derivation out of node project with the minimal flake

Why aren't systems like NixOS and GNU Guix more popular?
The DavHau/dream2nix project aims to be a generic solution for this issue by splitting the problem into specific stages, each of which can be configured individually (e.g., changing the level of purity)
