Tips and Tricks

Use Authinfo.gpg to retrieve the RTorrent URL

This snippet allows you to store your RTorrent RPC URL in a gpg-encrypted file. Make sure you have GPG set up before continuing.

First append to the ~/.authinfo.gpg file like so:

machine <hostname> login <username>^rtorrent password https://<username>:<password>@<hostname>:<port><path>/RPC2

Then add this to your emacs config:

(defun my/fetch-password (&rest params)
  "Fetch password from ~/authinfo.gpg."
  (require 'auth-source)
  (let ((match (car (apply 'auth-source-search params))))
    (if match
        (let ((secret (plist-get match :secret)))
          (if (functionp secret)
              (funcall secret)
            secret))
      (error "Password not found for %S" params))))

(setq mentor-rtorrent-external-rpc
      (my/fetch-password :host "<hostname>" :user "<username>^rtorrent"))
