How do I get the path from which init.el was loaded?

Question

I am looking to create a custom config for emacs to use for Erlang work and I want to refer to my custom EDTS repo as being under the directory from which init.el was loaded. Right now I have this:

(add-to-list 'load-path "~/.emacs-edts/edts/")

But I would rather not hardcode it and refer to it by variable.

Suggestions?

Answer 1

Strictly speaking the answer is (file-name-directory user-init-file), but instead see C-hv user-emacs-directory

Answer 2

I have the following snippet in my init.el:

(setq my-init-dir
    (file-name-directory
        (or load-file-name (buffer-file-name))))

This has the advantage of working whether init.el is in your emacs.d directory or not.
