direnv not updated on nixos

[mihem]

@b-rodrigues while

use nix
mkdir $TMP

worked fine for me on ubuntu with direnv extension in vscode,on nixos this did not reload the direnv environment
So initially direnv loaded the correct environment and everythings works fine, but after adding a package via rix, this did not work in vscode (while it works fine via terminal). Even if i told direnv extension to reset and restart the environment, the new packages could not be loaded in the env.
LLM told me this has something to do with .envrc and wrong cache invalidation.

using .envrc

watch_file default.nix

export TMP="$PWD/.direnv/tmp"
export TMPDIR="$TMP"
mkdir -p "$TMP"

use nix

fixed it for me. Then direnv automatically asked if i want to reload the env and then new packages can be loaded.
I am not sure

export TMP="$PWD/.direnv/tmp"
export TMPDIR="$TMP"
mkdir -p "$TMP"

these lines are strictly needed?

Ah i think I could also fix this by using

terminal.integrated.inheritEnv = true

in vscode.

I had this false in Ubuntu and in worked fine, but it seems this is required on Nixos?

[b-rodrigues]

this isn't related to rix?

[mihem]

yeah, kind of., we had that discussion like a year ago ;) when you first pointed me to direnv. It is part of: setting your IDE so that it works with the nix-shell env.
But agree this is more vscode-R setting than really rix. But it is realted to https://docs.ropensci.org/rix/articles/configuring-ide.html becuae chaning .envrc fixed things (but also changing vscode-R settings I think as I later realized)

i'll have to try it when I'll get a bit more time, as I don't use vscode. Everything still working as usual on emacs
