* INTRODUCTION Rudel is 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 and mode line of buffers for which Rudel has been activated. * GETTING STARTED Assuming Rudel has already been installed and auto loading has been set up, a global Rudel mode can be enabled as follows: : M-x global-rudel-minor-mode This will enabled Rudel's key bindings and menu entry. ** 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: 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 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. * 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 Rudel is licensed under the same terms as GNU Emacs. Local variables: mode: org end:
