nix3-edit: Open the source of the Nix expression of a package from nixpkgs in your `$EDITOR`.

$ nix edit ${nixpkgs#pkg}

try on your machine

The command "nix edit ${nixpkgs#pkg}" is executed in a shell environment. It uses the nix package manager and specifically the "nix edit" subcommand.

Here is an explanation of each part of the command:

"nix edit": This is a subcommand of the nix package manager that opens a specified package or derivation in an editor. It allows you to modify the package's derivation file or associated files.
"${nixpkgs#pkg}": This is a parameter expansion, specifically a substring replacement, used to specify the package to edit. The variable "nixpkgs" likely refers to the nixpkgs repository, which is a collection of packages for the nix package manager. The "#pkg" part removes the prefix "pkg" from the value of the "nixpkgs" variable, essentially stripping the "pkg" part from the package name.

So, when executing "nix edit ${nixpkgs#pkg}", the command will open the specified package in an editor, allowing you to make changes to its derivation/configuration. The specific package that will be opened depends on the value of the "nixpkgs" variable which is set in the environment.
