direnv: Edit the `.envrc` file in the default text editor and reload the environment on exit.

direnv

$ direnv edit ${-}

try on your machine

The command direnv edit ${-} is used to open the .envrc file in the current directory using the default text editor specified in the $EDITOR environment variable.

Here is how the command works:

direnv is a command-line tool that helps to automatically load and unload environment variables based on the current directory. It is often used in development environments to manage project-specific configurations.
edit is a subcommand of direnv that instructs it to open the .envrc file for editing.
${-} is a special variable in Unix-like systems that expands to the flags used to start the current shell. It is commonly used as a way to pass the same flags to another command or script.

By using ${-} in the command, it ensures that the same flags used to start the current shell are passed to the command responsible for opening the .envrc file. This allows for consistent behavior, such as preserving any shell options or environment variables set at the shell level.
