Make Direnv Less Noisy

I've been using direnv to manage project and folder specific environment variables for a bit now. I've found it to be pretty seamless. It can feel like it is littering my shell with too much output when I change directories though.

There are two levers to control its output.

First, the direnv logs (e.g. direnv: loading ~/.../.envrc) can be controlled with the DIRENV_LOG_FORMAT env var. Add this to the ~/.config/direnv/direnvrc file (add that directory and file if necessary). You can leave it blank to altogether hide log messages or you can gray-out the log messages like this:

export DIRENV_LOG_FORMAT=$'\033[2mdirenv: %s\033[0m'

Second, you can hide the env var diff with a separate config. This diff is not covered under the umbrella of logs controlled by the above setting. Set hide_env_diff in the ~/.config/direnv/direnv.toml file:

[global]
hide_env_diff = true

This second config was only added as of v2.34.0.
