226 @chapter Installation
228 ERC may be compiled and installed on your machine.
230 This section may be skipped if you are using the version of ERC that
233 @subsubheading Compilation
235 This is an optional step, since Emacs Lisp source code does not
236 necessarily have to be byte-compiled. It will yield a speed increase,
239 A working copy of Emacs or XEmacs is needed in order to compile ERC. By
240 default, the program that is installed with the name @command{emacs}
243 If you want to use the @command{xemacs} binary to perform the
244 compilation, you would need to edit @file{Makefile} in the top-level
245 directory as follows. You can put either a full path to an Emacs or
246 XEmacs binary or just the command name, as long as it is in the
251 SITEFLAG = -no-site-file
254 Running @code{make} should compile the ERC source files in the
255 @file{lisp} directory.
257 @subsubheading Installation
259 ERC may be installed into your file hierarchy by doing the following.
261 Edit the @file{Makefile} file so that @env{ELISPDIR} points to where you
262 want the source and compiled ERC files to be installed and
263 @env{INFODIR} indicates where to put the ERC manual. Of course, you
264 will want to edit @env{EMACS} and @env{SITEFLAG} as shown in the
265 Compilation section if you are using XEmacs.
267 If you are installing ERC on a Debian system, you might want to change
268 the value of @env{INSTALLINFO} as specified in @file{Makefile}.
270 Run @code{make} as a normal user.
272 Run @code{make install} as the root user if you have chosen installation
273 locations that require this.
276 @node Getting Started, Keystroke Summary, Installation, Top
277 @comment node-name, next, previous, up
278 @chapter Getting Started
281 To use ERC, add the directory containing its files to your
282 @code{load-path} variable, in your @file{.emacs} file. Then, load ERC
283 itself. An example follows.
289 Once ERC is loaded, the command @kbd{M-x erc} will start ERC and
290 prompt for the server to connect to.
292 If you want to place ERC settings in their own file, you can place them
293 in @file{~/.emacs.d/.ercrc.el}, creating it if necessary.
295 If you would rather use the Customize interface to change how ERC works,
296 do @kbd{M-x customize-group RET erc RET}. In particular, ERC comes with
297 lots of modules that may be enabled or disabled; to select which ones
298 you want, do @kbd{M-x customize-variable RET erc-modules RET}.

305 @node Sample Session, Special Features, Getting Started, Getting Started
306 @comment node-name, next, previous, up
307 @section Sample Session
309 This is an example ERC session which shows how to connect to the #emacs
310 channel on Freenode. Another IRC channel on Freenode that may be of
311 interest is #erc, which is a channel where ERC users and developers hang
316 @item Connect to Freenode
318 Run @kbd{M-x erc}. Use ``irc.freenode.net'' as the IRC server, ``6667''
319 as the port, and choose a nickname.
321 @item Get used to the interface
323 Switch to the ``irc.freenode.net:6667'' buffer, if you're not already
324 there. You will see first some messages about checking for ident, and
325 then a bunch of other messages that describe the current IRC server.
327 @item Join the #emacs channel
329 In that buffer, type ``/join SPC #emacs'' and hit @kbd{RET}. Depending
330 on how you've set up ERC, either a new buffer for ``#emacs'' will be
331 displayed, or a new buffer called ``#emacs'' will be created in the
332 background. If the latter, switch to the ``#emacs'' buffer. You will
333 see the channel topic and a list of the people who are currently on the
336 @item Register your nickname with Freenode
338 If you would like to be able to talk with people privately on the
339 Freenode network, you will have to ``register'' your nickname. To do
340 so, switch to the ``irc.freenode.net:6667'' buffer and type ``/msg
341 NickServ register <password>'', replacing ``<password>'' with your
342 desired password. It should tell you that the operation was successful.
344 @item Talk to people in the channel
346 If you switch back to the ``#emacs'' buffer, you can type a message, and
347 everyone on the channel will see it.
349 @item Open a query buffer to talk to someone
351 If you want to talk with someone in private (this should usually not be
352 done for technical help, only for personal questions), type ``/query
353 <nick>'', replacing ``<nick>'' with the nickname of the person you would
354 like to talk to. Depending on how ERC is set up, you will either see a
355 new buffer with the name of the person, or such a buffer will be created
356 in the background and you will have to switch to it. Begin typing
357 messages, and you will be able to have a conversation.
359 Note that if the other person is not registered, you will not be able to

366 @section Special Features
368 ERC has some features that distinguish it from some IRC clients.
372 @item multiple channels and multiple servers
374 Every channel is put in a separate buffer. Several IRC servers may be
375 connected to at the same time.
377 @cindex query buffers
378 @item private message separation
380 Private conversations are treated as channels, and are put into separate
381 buffers in Emacs. We call these ``query buffers''.
385 Some occurences of words can be highlighted, which makes it easier to
386 track different kinds of conversations.
390 ERC can notify you that certain users are online.
392 @item channel tracking
394 Channels can be hidden and conversation continue in the background. You
395 are notified when something is said in such a channel that is not
396 currently visible. This makes it easy to get Real Work done while still
397 maintaining an IRC presence.
399 @item nick completion
401 ERC can complete words upon hitting @kbd{TAB}, which eases the writing
402 of nicknames in messages.
407 Past actions are kept in history rings for future use. To navigate a
408 history ring, hit @kbd{M-p} to go backwards and @kbd{M-n} to go
411 @item multiple languages
413 Different channels and servers may have different language encodings.
415 In addition, it is possible to translate the messages that ERC uses into
416 multiple languages. Please contact the developers of ERC at
417 @email{erc-discuss@@gnu.org} if you are interested in helping with the
422 Users can load scripts (e.g. auto greeting scripts) when ERC starts up.
424 It is also possible to make custom IRC commands, if you know a little
425 Emacs Lisp. Just make an Emacs Lisp function and call it
426 @code{erc-cmd-NEWCOMMAND}, where @code{NEWCOMMAND} is the name of the
427 new command in capital letters.
431 If the connection goes away at some point, ERC will try to reconnect
432 automatically. If it fails to reconnect, and you want to try to
433 manually reestablish the connection at some later point, switch to an
434 ERC buffer and run the @code{/RECONNECT} command.

674 @section Connecting to an IRC Server
677 The easiest way to connect to an IRC server is to call @kbd{M-x erc}.
678 If you want to assign this function to a keystroke, the following will
679 help you figure out its parameters.
682 Select connection parameters and run ERC.
683 Non-interactively, it takes the following keyword arguments.
690 @item @var{full-name}
693 That is, if called with the following arguments, @var{server} and
694 @var{full-name} will be set to those values, whereas
695 @code{erc-compute-port}, @code{erc-compute-nick} and
696 @code{erc-compute-full-name} will be invoked for the values of the other

714 @item The @code{erc-server} option
715 @item The value of the IRCSERVER environment variable
716 @item The @code{erc-default-server} variable
721 @defopt erc-server nil
722 IRC server to use if one is not provided.
727 @defun erc-compute-port &optional port
728 Return a port for an IRC server.
730 This tries a number of increasingly more default methods until a non-nil
734 @item @var{port} (the argument passed to this function)
735 @item The @code{erc-port} option
736 @item The @code{erc-default-port} variable
742 IRC port to use if not specified.
744 This can be either a string or a number.
749 @defun erc-compute-nick &optional nick
750 Return user's IRC nick.
752 This tries a number of increasingly more default methods until a
753 non-nil value is found.
756 @item @var{nick} (the argument passed to this function)
757 @item The @code{erc-nick} option
758 @item The value of the IRCNICK environment variable
759 @item The result from the @code{user-login-name} function
765 Nickname to use if one is not provided.
767 This can be either a string, or a list of strings.
768 In the latter case, if the first nick in the list is already in use,
769 other nicks are tried in the list order.
772 @defopt erc-nick-uniquifier
773 The string to append to the nick if it is already in use.
776 @defopt erc-try-new-nick-p
777 If the nickname you chose isn't available, and this option is non-nil,
778 ERC should automatically attempt to connect with another nickname.
780 You can manually set another nickname with the /NICK command.
783 @subheading Full name
785 @defun erc-compute-full-name &optional full-name
786 Return user's full name.

794 @item The value of the IRCNAME environment variable
795 @item The result from the @code{user-full-name} function

905 After you have read this guide, if you still have questions about ERC,
906 or if you have bugs to report, there are several places you can go.
911 @uref{http://www.emacswiki.org/cgi-bin/wiki/EmacsIRCClient} is the
912 emacswiki.org page for ERC. Anyone may add tips, hints, or bug
916 There are several mailing lists for ERC. To subscribe, visit
917 @uref{http://savannah.gnu.org/mail/?group=erc}.
919 The mailing lists are also available on Gmane.
920 (@url{http://gmane.org/}). Gmane provides additional methods for
921 accessing the mailing lists, adding content to them, and searching them.

946 @cindex history, of ERC
948 ERC was originally written by Alexander L. Belikoff
949 @email{abel@@bfr.co.il} and Sergey Berezin
950 @email{sergey.berezin@@cs.cmu.edu}. They stopped development around
951 December 1999. Their last released version was ERC 2.0.
953 P.S.: If one of the original developers of ERC reads this, we'd like to
954 receive additional information for this file and hear comments in
960 In June 2001, Mario Lang @email{mlang@@delysid.org} and Alex Schroeder
961 @email{alex@@gnu.org} took over development and created a ERC Project at
962 @uref{http://sourceforge.net/projects/erc}.
964 In reaction to a mail about the new ERC development effort, Sergey
965 Berezin said, ``First of all, I'm glad that my version of ERC is being
966 used out there. The thing is, I do not have free time and enough
967 incentive anymore to work on ERC, so I would be happy if you guys take
968 over the project entirely.''
970 So we happily hacked away on ERC, and soon after (September 2001)
971 released the next "stable" version, 2.1.
973 Most of the development of the new ERC happened on #emacs on
974 irc.openprojects.net. Over time, many people contributed code, ideas,
975 bugfixes, and a lot of alpha/beta/gamma testing.
977 See the @file{CREDITS} file for a list of contributors.
981 ERC 3.0 was released.
985 ERC 4.0 was released.
989 ERC 5.0 was released. Michael Olson @email{mwolson@@gnu.org} became
990 the release manager and eventually the maintainer.
992 After some discussion between him and the Emacs developers, it was
993 decided to include ERC in Emacs.
997 ERC 5.1 was released. It was subsequently included in Emacs 22.
999 ERC became an official GNU project, and development moved to
1000 @uref{http://sv.gnu.org/projects/erc}. We switched to using GNU Arch as
1001 our revision control system. Our mailing list address changed as well.
