Direnv

Many people use direnv to load an environment upon entering a directory as well as unloading it when exiting the directory. Configuring direnv to work with nushell requires nushell version 0.66 or later.

Configuring direnv

To make direnv work with nushell the way it does with other shells, we can use the "hooks" functionality:

$env.config = {
  hooks: {
    pre_prompt: [{ ||
        let direnv = (direnv export json | from json | default {})
        if ($direnv | is-empty) {
            return
        }
        $direnv
        | items {|key, value|
           {
              key: $key
              value: (if $key in $env.ENV_CONVERSIONS {
                do ($env.ENV_CONVERSIONS | get $key | get from_string) $value
              } else {
                  $value
              })
            }
        } | transpose -ird | load-env
    }]
  }
}

With that configuration in place, direnv should now work with nushell.
