devdocs.el VS envrc

emacs integration: https://github.com/astoff/devdocs.el

devdocs.el: Documentation reader with quick and handy lookup commands. It is similar to the built-in Info reader, but has a different (likely larger) document coverage.

I use this (https://github.com/astoff/devdocs.el) emacs package to download devdocs locally and access them from emacs, which is pretty great.

Support for other languages is a good point. Most don't ship info documentation. :P If you want something inside a normal Emacs buffer rather than a separate browser-like application, maybe you'd enjoy devdocs.io and astoff's devdocs.el package.

+1. I'm using an amazing Emacs package that treats DevDocs kinda like Dash: https://github.com/astoff/devdocs.el

info-like: https://github.com/astoff/devdocs.el

devdocs.el to read documentation

Wow, so many devdocs packages! Of the two I mentioned, devdocs-browser is the one in the emacs-devdocs-browser repo you found. But the other one I was thinking of didn't turn up in your search: devdocs. I wasn't aware of the others you found, probably because they aren't on GNU ELPA or on MELPA.

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.
