A collaborative editing framework for Emacs

* INTRODUCTION Rudel is a collaborative editing environment for GNU Emacs. Its purpose is to share buffers with other users in order to edit the contents of those buffers collaboratively. Rudel supports multiple backends to enable communication with other collaborative editors using different protocols, though currently Obby (for use with the Gobby editor) is the only fully-functional one. Since Rudel is not an application, but an extension to Emacs, it is not started and used like most applications (not even Emacs applications like Gnus). Rudel mostly works in the background to change the behavior of the set of Emacs buffers for which it has been activated. The user interface consists of a set of key bindings, a menu entry and some visual status indicators, which are added to the text, header line and/or mode line of buffers for which Rudel has been activated. * GETTING STARTED Assuming Rudel has already been installed (see file:INSTALL) and auto loading has been set up, a global Rudel mode can be enabled as follows: : M-x global-rudel-minor-mode This will enable Rudel's key bindings and add a menu entry. To enable this mode permanently, the following fragment can be added to the Emacs initialization file (usually file:~/.emacs): #+BEGIN_SRC emacs-lisp (global-rudel-minor-mode 1) #+END_SRC ** JOINING A SESSION : M-x rudel-join-session [ C-c c j ] Depending on the installed Rudel backends, system environment and configuration, a number of questions will be asked, followed by an attempt to join session described by your answers. A typical example of the questions asked when joining a session may look like this: #+BEGIN_EXAMPLE Server: localhost RET Port (default 6522): RET Username: jan RET Color: light sky blue RET Use Encryption (y or n): n RET Global Password: RET User Password: RET #+END_EXAMPLE *IMPORTANT*: For sessions using the obby backend (like in the example above), the following restriction has to be taken into account: + When the server is Rudel inside an Emacs process: Encryption cannot be used currently in this case. Consequently the answer to the `Use Encryption (y or n):' prompt above has to be `n RET'. + When the server is a Gobby process: Gobby only supports encrypted connections. So the answer has to be `y RET' is this case. It is possible to configure frequently used sessions using the customization options `rudel-configured-sessions'. When one or more sessions are configured, `rudel-join-session' will provide choices like "my-configured-session", ... and "ask-protocol". Selecting "ask-protocol" invokes the behavior described above. Selecting one of the configured sessions connects to that session without asking for all the data. ** HOSTING A SESSION : M-x rudel-host-session [ C-c c h ] Note that the session starts out without any participating users (This is sometimes referred to as being a dedicated server). If you want to participate in the session you host, you have to join it as described above. * REPORTING BUGS AND GETTING HELP ** EmacsWiki The EmacsWiki page about Rudel has [[http://www.emacswiki.org/emacs/Rudel#toc8][a section for feedback and questions]]. Feel free leave feedback or ask questions there. If a reply does not occur promptly, try writing to the mailing list of visiting the IRC channel. ** Issue Tracker Bugs can be reported using the issue tracker on the sourceforge project page: http://sourceforge.net/tracker/?group_id=249139 ** Mailing List Another possibility for getting help and reporting problems is writing to the Rudel mailing list: http://sourceforge.net/mail/?group_id=249139 ** IRC Channel Rudel users and developers can also be reached on the #rudel IRC channel on the freenode network: irc:/irc.freenode.net:6667/#rudel * KNOWN ISSUES + Publishing eshell buffers will cause your session to be disconnected since eshell disables the hooks that Rudel uses to catch changes to the buffer. As a workaround, you can use M-x ansi-term or another terminal emulator. * LICENSE This file is part of Rudel.
