Choose to install a release if you want to minimize risk.

Errors are corrected in development first.  User-visible changes will be
announced on the @email{erc-discuss@@gnu.org} mailing list.
@pxref{Getting Help and Reporting Bugs}.

@cindex releases, Debian package
@cindex Debian package for ERC
Debian users can get ERC via apt-get.  The @file{erc} package is
available in the official Debian repository.

@cindex releases, from source
Alternatively, you can download the latest release from
@uref{http://ftp.gnu.org/gnu/erc}, or your local GNU mirror.

@node Development,  , Releases, Obtaining ERC
@comment  node-name,  next,  previous,  up
@section Development
@cindex development

Choose the development version if you want to live on the bleeding edge
of ERC development or try out new features before release.

@cindex git version control system, using
The git version control system allows you to keep up-to-date with the
latest changes to the development version of ERC.  It also allows you
to contribute changes (via commits, if you are have developer access to
the repository, or via patches, otherwise).  If you would like to
contribute to ERC development, it is highly recommended that you use
git.

If you are new to git, you might find this tutorial helpful:
@uref{http://www.kernel.org/pub/software/scm/git/docs/tutorial.html}.

Downloading ERC with git and staying up-to-date involves the following
steps.

@enumerate
@item Install git.

@itemize @bullet
@item Debian and Ubuntu: @kbd{apt-get install git-core}.
@item Windows: @uref{http://git.or.cz/gitwiki/WindowsInstall}.
@item Other operating systems: download, compile, and install the source
from @uref{http://www.kernel.org/pub/software/scm/git/}, or find a git
package for your operating system.
@end itemize

@item Download the ERC development branch.

If you have developer access to ERC, do:

@example
git clone ssh://loginname@@git.sv.gnu.org/srv/git/erc.git
@end example

otherwise, do:

@example
git clone git://git.sv.gnu.org/erc.git
@end example

If you are behind a restrictive firewall, and do not have developer
access, then do the following instead:

@example
git clone http://git.sv.gnu.org/r/erc.git
@end example

@item List upstream changes that are missing from your local copy.
Do this whenever you want to see whether new changes have been committed
to ERC.  If you wish, you may skip this step and proceed directly to
the ``update'' step.

@example
# Change to the source directory you are interested in.
cd erc

# Fetch new changes from the repository, but don't apply them yet
git fetch origin

# Display log messages for the new changes
git log HEAD..origin
@end example

``origin'' is git's name for the location where you originally got ERC
from.  You can change this location at any time by editing the
@file{.git/config} file in the directory where the ERC source was
placed.

@cindex updating ERC with git
@item Update to the latest version by pulling in any missing changes.

@example
cd erc
git pull origin
@end example

git will show how many files changed, and will provide a visual display
for how many lines were changed in each file.

@end enumerate

There are other ways to interact with the ERC repository.

@itemize
@item Browse git repo: @uref{http://git.sv.gnu.org/gitweb/?p=erc.git}
@item Latest development snapshot: @uref{http://mwolson.org/static/dist/erc-latest.tar.gz}
@item Latest development snapshot (zip file): @uref{http://mwolson.org/static/dist/erc-latest.zip}
@end itemize

The latest development snapshot can lag behind the git repo by as much
as 20 minutes, but never more than that.

For further information on committing changes to ERC and performing
development, please consult
@uref{http://emacswiki.org/cgi-bin/wiki/ErcDevelopment}.


@node Installation, Getting Started, Obtaining ERC, Top
@comment  node-name,  next,  previous,  up
@chapter Installation

ERC may be compiled and installed on your machine.

This section may be skipped if you are using the version of ERC that
comes with Emacs.

@subsubheading Compilation

This is an optional step, since Emacs Lisp source code does not
necessarily have to be byte-compiled.  It will yield a speed increase,
though.

A working copy of Emacs or XEmacs is needed in order to compile ERC.  By
default, the program that is installed with the name @command{emacs}
will be used.

If you want to use the @command{xemacs} binary to perform the
compilation, you would need to edit @file{Makefile} in the top-level
directory as follows.  You can put either a full path to an Emacs or
XEmacs binary or just the command name, as long as it is in the
@env{PATH}.

@example
EMACS    = xemacs
SITEFLAG = -no-site-file
@end example

Running @code{make} should compile the ERC source files in the
@file{lisp} directory.

@subsubheading Installation

ERC may be installed into your file hierarchy by doing the following.

Edit the @file{Makefile} file so that @env{ELISPDIR} points to where you
want the source and compiled ERC files to be installed and
@env{INFODIR} indicates where to put the ERC manual.  Of course, you
will want to edit @env{EMACS} and @env{SITEFLAG} as shown in the
Compilation section if you are using XEmacs.

If you are installing ERC on a Debian system, you might want to change
the value of @env{INSTALLINFO} as specified in @file{Makefile}.

Run @code{make} as a normal user.

Run @code{make install} as the root user if you have chosen installation
locations that require this.


@node Getting Started, Keystroke Summary, Installation, Top
@comment  node-name,  next,  previous,  up
@chapter Getting Started
@cindex settings

To use ERC, add the directory containing its files to your
@code{load-path} variable, in your @file{.emacs} file.  Then, load ERC
itself.  An example follows.

@lisp
(require 'erc)
@end lisp

Once ERC is loaded, the command @kbd{M-x erc} will start ERC and
prompt for the server to connect to.

If you want to place ERC settings in their own file, you can place them
in @file{~/.emacs.d/.ercrc.el}, creating it if necessary.

If you would rather use the Customize interface to change how ERC works,
do @kbd{M-x customize-group RET erc RET}.  In particular, ERC comes with
lots of modules that may be enabled or disabled; to select which ones
you want, do @kbd{M-x customize-variable RET erc-modules RET}.

@end menu

@node Sample Session, Special Features, Getting Started, Getting Started
@comment  node-name,  next,  previous,  up
@section Sample Session

This is an example ERC session which shows how to connect to the #emacs
channel on Freenode.  Another IRC channel on Freenode that may be of
interest is #erc, which is a channel where ERC users and developers hang
out.

@itemize @bullet

@item Connect to Freenode

Run @kbd{M-x erc}.  Use ``irc.freenode.net'' as the IRC server, ``6667''
as the port, and choose a nickname.

@item Get used to the interface

Switch to the ``irc.freenode.net:6667'' buffer, if you're not already
there.  You will see first some messages about checking for ident, and
then a bunch of other messages that describe the current IRC server.

@item Join the #emacs channel

In that buffer, type ``/join SPC #emacs'' and hit @kbd{RET}.  Depending
on how you've set up ERC, either a new buffer for ``#emacs'' will be
displayed, or a new buffer called ``#emacs'' will be created in the
background.  If the latter, switch to the ``#emacs'' buffer.  You will
see the channel topic and a list of the people who are currently on the
channel.

@item Register your nickname with Freenode

If you would like to be able to talk with people privately on the
Freenode network, you will have to ``register'' your nickname.  To do
so, switch to the ``irc.freenode.net:6667'' buffer and type ``/msg
NickServ register <password>'', replacing ``<password>'' with your
desired password.  It should tell you that the operation was successful.

@item Talk to people in the channel

If you switch back to the ``#emacs'' buffer, you can type a message, and
everyone on the channel will see it.

@item Open a query buffer to talk to someone

If you want to talk with someone in private (this should usually not be
done for technical help, only for personal questions), type ``/query
<nick>'', replacing ``<nick>'' with the nickname of the person you would
like to talk to.  Depending on how ERC is set up, you will either see a
new buffer with the name of the person, or such a buffer will be created
in the background and you will have to switch to it.  Begin typing
messages, and you will be able to have a conversation.

Note that if the other person is not registered, you will not be able to
talk with them.

@end itemize

@node Special Features, , Sample Session, Getting Started
@comment  node-name,  next,  previous,  up
@section Special Features

ERC has some features that distinguish it from some IRC clients.

@itemize @bullet

@item multiple channels and multiple servers

Every channel is put in a separate buffer.  Several IRC servers may be
connected to at the same time.

@cindex query buffers
@item private message separation

Private conversations are treated as channels, and are put into separate
buffers in Emacs.  We call these ``query buffers''.

@item highlighting

Some occurrences of words can be highlighted, which makes it easier to
track different kinds of conversations.

@item notification

ERC can notify you that certain users are online.

@item channel tracking

Channels can be hidden and conversation continue in the background.  You
are notified when something is said in such a channel that is not
currently visible.  This makes it easy to get Real Work done while still
maintaining an IRC presence.

@item nick completion

ERC can complete words upon hitting @kbd{TAB}, which eases the writing
of nicknames in messages.

@cindex history ring
@item history

Past actions are kept in history rings for future use.  To navigate a
history ring, hit @kbd{M-p} to go backwards and @kbd{M-n} to go
forwards.

@item multiple languages

Different channels and servers may have different language encodings.

In addition, it is possible to translate the messages that ERC uses into
multiple languages.  Please contact the developers of ERC at
@email{erc-discuss@@gnu.org} if you are interested in helping with the
translation effort.

@item user scripting

Users can load scripts (e.g. auto greeting scripts) when ERC starts up.

It is also possible to make custom IRC commands, if you know a little
Emacs Lisp.  Just make an Emacs Lisp function and call it
@code{erc-cmd-NEWCOMMAND}, where @code{NEWCOMMAND} is the name of the
new command in capital letters.

@item auto reconnect

If the connection goes away at some point, ERC will try to reconnect
automatically.  If it fails to reconnect, and you want to try to
manually reestablish the connection at some later point, switch to an
ERC  buffer and run the @code{/RECONNECT} command.

@section Connecting to an IRC Server
@cindex connecting

The easiest way to connect to an IRC server is to call @kbd{M-x erc}.
If you want to assign this function to a keystroke, the following will
help you figure out its parameters.

@defun erc
Select connection parameters and run ERC.
Non-interactively, it takes the following keyword arguments.

@itemize @bullet
@item @var{server}
@item @var{port}
@item @var{nick}
@item @var{password}
@item @var{full-name}
@end itemize

That is, if called with the following arguments, @var{server} and
@var{full-name} will be set to those values, whereas
@code{erc-compute-port}, @code{erc-compute-nick} and
@code{erc-compute-full-name} will be invoked for the values of the other
parameters.

@example
(erc :server "irc.freenode.net" :full-name "Harry S Truman")
@end example
@end defun

@subheading Server

@defun erc-compute-server &optional server
Return an IRC server name.

This tries a number of increasingly more default methods until a non-nil
value is found.

@itemize @bullet
@item @var{server} (the argument passed to this function)
@item The @code{erc-server} option
@item The value of the IRCSERVER environment variable
@item The @code{erc-default-server} variable
@end itemize

@end defun

@defopt erc-server nil
IRC server to use if one is not provided.
@end defopt

@subheading Port

@defun erc-compute-port &optional port
Return a port for an IRC server.

This tries a number of increasingly more default methods until a non-nil
value is found.

@itemize @bullet
@item @var{port} (the argument passed to this function)
@item The @code{erc-port} option
@item The @code{erc-default-port} variable
@end itemize

@end defun

@defopt erc-port
IRC port to use if not specified.

This can be either a string or a number.
@end defopt

@subheading Nick

@defun erc-compute-nick &optional nick
Return user's IRC nick.

This tries a number of increasingly more default methods until a
non-nil value is found.

@itemize
@item @var{nick} (the argument passed to this function)
@item The @code{erc-nick} option
@item The value of the IRCNICK environment variable
@item The result from the @code{user-login-name} function
@end itemize

@end defun

@defopt erc-nick
Nickname to use if one is not provided.

This can be either a string, or a list of strings.
In the latter case, if the first nick in the list is already in use,
other nicks are tried in the list order.
@end defopt

@defopt erc-nick-uniquifier
The string to append to the nick if it is already in use.
@end defopt

@defopt erc-try-new-nick-p
If the nickname you chose isn't available, and this option is non-nil,
ERC should automatically attempt to connect with another nickname.

You can manually set another nickname with the /NICK command.
@end defopt

@subheading Full name

@defun erc-compute-full-name &optional full-name
Return user's full name.

This tries a number of increasingly more default methods until a
non-nil value is found.

@itemize @bullet
@item @var{full-name} (the argument passed to this function)
@item The @code{erc-user-full-name} option
@item The value of the IRCNAME environment variable
@item The result from the @code{user-full-name} function
@end itemize

@end defun

@defopt erc-user-full-name

@chapter History
@cindex history, of ERC

ERC was originally written by Alexander L. Belikoff
@email{abel@@bfr.co.il} and Sergey Berezin
@email{sergey.berezin@@cs.cmu.edu}.  They stopped development around
December 1999.  Their last released version was ERC 2.0.

P.S.: If one of the original developers of ERC reads this, we'd like to
receive additional information for this file and hear comments in
general.

@itemize
@item 2001

In June 2001, Mario Lang @email{mlang@@delysid.org} and Alex Schroeder
@email{alex@@gnu.org} took over development and created a ERC Project at
@uref{http://sourceforge.net/projects/erc}.

In reaction to a mail about the new ERC development effort, Sergey
Berezin said, ``First of all, I'm glad that my version of ERC is being
used out there.  The thing is, I do not have free time and enough
incentive anymore to work on ERC, so I would be happy if you guys take
over the project entirely.''

So we happily hacked away on ERC, and soon after (September 2001)
released the next "stable" version, 2.1.

Most of the development of the new ERC happened on #emacs on
irc.openprojects.net.  Over time, many people contributed code, ideas,
bugfixes, and a lot of alpha/beta/gamma testing.

See the @file{CREDITS} file for a list of contributors.

@item 2003

ERC 3.0 was released.

@item 2004

ERC 4.0 was released.

@item 2005

ERC 5.0 was released.  Michael Olson @email{mwolson@@gnu.org} became
the release manager and eventually the maintainer.

After some discussion between him and the Emacs developers, it was
decided to include ERC in Emacs.

@item 2006

ERC 5.1 was released.  It was subsequently included in Emacs 22.

ERC became an official GNU project, and development moved to
@uref{http://sv.gnu.org/projects/erc}.  We switched to using GNU Arch as
our revision control system.  Our mailing list address changed as well.

@item 2007

We switched to using git for our version control system.
