direnv printing environment diff even with `hide_env_diff = true`

I am using direnv 2.35.0 (and nix-direnv 3.0.6, though the behaviour happens even without use nix or use flake) and direnv insists on printing the environment diff even though I have hide_env_diff = true in my .config/direnv/direnv.toml configuration file.

Here's an example transcript in case it's helpful:

shaver on stebe ~ 
❯ cd -
~/tmp
direnv: loading ~/tmp/.envrc
direnv: export +SLAM

shaver on stebe ~/tmp 
❯ cat .envrc             
export SLAM=bam

shaver on stebe ~/tmp 
❯ cat ~/.config/direnv/direnv.toml 
[global]
hide_env_diff = true

How can I properly suppress the printing of the environment diff? When moving into some use flake directories the list is pretty long and annoying.

Solution

  • If you installed nix-direnv by setting

    programs.direnv.enable=true;

    in your configuration.nix, then this changes your DIRENV_CONFIG environment variable to /etc/direnv/, thus never sourcing your direnv.toml file in your local configuration. Changing this environment variable back directly will not work, however, as configuration to start nix-direnv is added inside /etc/direnv/direnvrc.

    I solved the problem by adding

    environment.etc."direnv/direnv.toml".text = ''
  [global]
  hide_env_diff = true
'';

    to my configuration.nix, which adds the direnv.toml file with the specified content to /etc/direnv. You will then have to modify this text if you want to add other options.
