envrc VS dotemacs

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.

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.

Also take a look at the envrc package. I think it handles multiple projects better.

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.

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

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.

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

As an alternative to emacs-direnv, I’d recommend the “envrc” package.

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.

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.

You can read my dotemacs here if you'd like I have isolated the packages with use-package deferred to when they're needed, added a couple useful functions, etc.

You can check it out here. I'll gladly take advice on improving it!

I have a setup with LSP-mode which you can check out. I've also written a snippet for a python config some time ago.

If you check out my dotemacs I have stuff I use for web development, I mostly use tide for JS and jQuery.

You can take a look at my dotemacson gitlab I have a LaTeX folder with custom latex classes. which are quite simple.

I've upgraded my config from elpy to lsp-mode but you can find a gist here, I hope it'll help you.
