[[https://elpa.nongnu.org/nongnu/mentor.html][https://elpa.nongnu.org/nongnu/mentor.svg]]



mentor is a [[https://www.gnu.org/software/emacs][GNU Emacs]] frontend for the [[https://rakshasa.github.io/rtorrent/][rTorrent]] bittorrent client.



By default, it will start and run rTorrent from within Emacs but can also be

configured to use an external rTorrent instance over XML-RPC.



This project aims to provide a feature complete and highly customizable

interface, that will feel familiar to Emacs users.  Key bindings are chosen to

be as close to the vanilla rTorrent curses interface as possible.



mentor still has some way to go before it can really be considered a complete

interface, so please moderate your expectations.  It works fine for many common

tasks though, and in some cases (dare we say?) much better than the standard

ncurses interface.

integration.  Sort your downloads in a breeze!



** Features



Here is a summary of some of the features:



- Show torrents in a table, with configurable columns.

- Search torrents using ~C-s~ (no more of the manual up/down).

- Mark and perform operations on more than one torrent at once.

- Sort torrents according to one or more criteria.

- Move downloads together with their data in one command.

- Switch between views, create new etc. (like numbers)

- Support for most standard operations.  (Start/stop/rehash/move etc.)

- Use all Emacs features you are used to: macros, Emacs Lisp, etc.



** Installing mentor



*** Installing through NonGNU ELPA (recommended)



You can install mentor from [[https://elpa.nongnu.org/][NonGNU ELPA]].  Find and install Mentor using this

command:



: M-x package-list-packages



NonGNU ELPA is configured by default in Emacs 28.1 or later.  For earlier

versions of Emacs, please see the specific instructions for how to configure

[[https://elpa.nongnu.org/][NonGNU ELPA]].



Mentor should work on Emacs 25 or later.  For the best performance I recommend

using at least Emacs 27.1, built with ~libxml~ support.  (See "Known issues"

below.)  I almost never test Mentor using old versions of Emacs, so please

report any issues you run into.



*** Installing mentor manually



You can also install mentor manually.  First, make sure you have the minimum

version of [[https://github.com/xml-rpc-el/xml-rpc-el][xml-rpc.el]] installed.



Clone this repository using:



: git clone https://github.com/skangas/mentor.git



Add this to your init.el:



: (add-to-list 'load-path "~/src/mentor/")

: (require 'mentor)



Change "~/src/mentor" to the path where you keep the mentor source code.



To byte-compile mentor, go to the source directory and run:



: make



To setup autoloading, you can add this to your Init file:



: (autoload 'mentor "mentor" nil t)



** Quick Start



Make sure that you have rTorrent (0.9.0 or later) installed on your system.



To start mentor, just run:



: M-x mentor



It should work out of the box, but you may want to do some additional

configuration.



** Configuration



*** General



You can find additional Mentor options in customize.



 : M-x customize-group RET mentor RET



Two useful variables to customize are ~mentor-rtorrent-download-directory~ and

~mentor-rtorrent-keep-session~.



*** External rTorrent



If you are already running rTorrent outside of Emacs, it is easy to configure

Mentor to use it.



Add this to your ~~/.rtorrent.rc~ and restart rTorrent:



: scgi_local = ~/.rtorrent-rpc.socket

: encoding.add = utf8



Customize ~mentor-rtorrent-external-rpc~, or add this to your Init file and

restart Emacs.



: (setq mentor-rtorrent-external-rpc "~/.rtorrent-rpc.socket")



You can also specify an absolute path:



: ;; Alternative 2: Absolute path

: (setq mentor-rtorrent-external-rpc "/path/to/rtorrent-rpc.socket")



It is also possible to connect to rtorrent over http.  There are instructions on

configuring this on the [[https://github.com/rakshasa/rtorrent/wiki/RPC-Setup-XMLRPC][rtorrent wiki]].



: ;; Alternative 3: Use a web server

: (setq mentor-rtorrent-external-rpc "https://127.0.0.1:8080/RPC2")



Finally, you can connect directly to rtorrent over scgi.  However, anyone that

can send rtorrent xmlrpc requests can in all likelihood also execute arbitrary

code as the user running rtorrent.  Therefore, this is inadvisable on anything

but the loopback device (e.g. ~127.0.0.1~) on single-user systems.



It is almost always easier and better to use a Unix domain socket (file) as

suggested above.



: ;; Alternative 4: Connect directly to rtorrent over scgi

: (setq mentor-rtorrent-external-rpc "scgi://127.0.0.1:5000")

** Known issues

- There is no view for trackers/peers/extra information.



- Mentor can be slow if Emacs was not built with ~libxml~ support.  This

  typically happens only when there are several hundreds, or even thousands, of

  torrents loaded in rtorrent.  Use an Emacs built with ~libxml~ support to

  avoid this issue.  (Support for ~libxml~ was added in Emacs 27.1.)
