174 | to contribute changes (via commits, if you are have developer access to | |
175 | the repository, or via patches, otherwise). If you would like to | |
176 | contribute to ERC development, it is highly recommended that you use | |
177 | git. | |

15db4a13 MO |
196 | @item Download the ERC development branch. |
197 | ||
198 | If you have developer access to ERC, do: | |
199 | ||
200 | @example | |
201 | git clone ssh://loginname@@git.sv.gnu.org/srv/git/erc.git | |
202 | @end example | |
203 | ||
204 | otherwise, do: | |
205 | ||
4009494e | 206 | @example |
15db4a13 | 207 | git clone git://git.sv.gnu.org/erc.git |
4009494e GM |
208 | @end example |
209 | ||
15db4a13 MO |
210 | If you are behind a restrictive firewall, and do not have developer |
211 | access, then do the following instead: | |
212 | ||
4009494e | 213 | @example |
15db4a13 | 214 | git clone http://git.sv.gnu.org/r/erc.git |
4009494e GM |
215 | @end example |
216 | ||
217 | @item List upstream changes that are missing from your local copy. | |
218 | Do this whenever you want to see whether new changes have been committed | |
15db4a13 MO |
219 | to ERC. If you wish, you may skip this step and proceed directly to |
220 | the ``update'' step. | |
4009494e GM |
221 | |
222 | @example | |
223 | # Change to the source directory you are interested in. | |
15db4a13 MO |
224 | cd erc |
225 | ||
226 | # Fetch new changes from the repository, but don't apply them yet | |
227 | git fetch origin | |
4009494e | 228 | |
15db4a13 MO |
229 | # Display log messages for the new changes |
230 | git log HEAD..origin | |
4009494e GM |
231 | @end example |
232 | ||
15db4a13 MO |
233 | ``origin'' is git's name for the location where you originally got ERC |
234 | from. You can change this location at any time by editing the | |
235 | @file{.git/config} file in the directory where the ERC source was | |
236 | placed. | |

269 | @chapter Installation | |
270 | ||
271 | ERC may be compiled and installed on your machine. | |
272 | ||
273 | This section may be skipped if you are using the version of ERC that | |
274 | comes with Emacs. | |
275 | ||
276 | @subsubheading Compilation | |
277 | ||
278 | This is an optional step, since Emacs Lisp source code does not | |
279 | necessarily have to be byte-compiled. It will yield a speed increase, | |
280 | though. | |
281 | ||
282 | A working copy of Emacs or XEmacs is needed in order to compile ERC. By | |
283 | default, the program that is installed with the name @command{emacs} | |
284 | will be used. | |
285 | ||
286 | If you want to use the @command{xemacs} binary to perform the | |
287 | compilation, you would need to edit @file{Makefile} in the top-level | |
288 | directory as follows. You can put either a full path to an Emacs or | |
289 | XEmacs binary or just the command name, as long as it is in the | |
290 | @env{PATH}. | |
291 | ||
292 | @example | |
293 | EMACS = xemacs | |
294 | SITEFLAG = -no-site-file | |
295 | @end example | |
296 | ||
297 | Running @code{make} should compile the ERC source files in the | |
298 | @file{lisp} directory. | |
299 | ||
300 | @subsubheading Installation | |
301 | ||
302 | ERC may be installed into your file hierarchy by doing the following. | |
303 | ||
304 | Edit the @file{Makefile} file so that @env{ELISPDIR} points to where you | |
305 | want the source and compiled ERC files to be installed and | |
306 | @env{INFODIR} indicates where to put the ERC manual. Of course, you | |
307 | will want to edit @env{EMACS} and @env{SITEFLAG} as shown in the | |
308 | Compilation section if you are using XEmacs. | |
309 | ||
310 | If you are installing ERC on a Debian system, you might want to change | |
311 | the value of @env{INSTALLINFO} as specified in @file{Makefile}. | |
312 | ||
313 | Run @code{make} as a normal user. | |
314 | ||
315 | Run @code{make install} as the root user if you have chosen installation | |
316 | locations that require this. | |

322 | @cindex settings | |
323 | ||
324 | To use ERC, add the directory containing its files to your | |
325 | @code{load-path} variable, in your @file{.emacs} file. Then, load ERC | |
326 | itself. An example follows. | |
327 | ||
328 | @lisp | |
329 | (require 'erc) | |
330 | @end lisp | |
331 | ||
332 | Once ERC is loaded, the command @kbd{M-x erc} will start ERC and | |
333 | prompt for the server to connect to. | |
334 | ||
335 | If you want to place ERC settings in their own file, you can place them | |
336 | in @file{~/.emacs.d/.ercrc.el}, creating it if necessary. | |
337 | ||
338 | If you would rather use the Customize interface to change how ERC works, | |
339 | do @kbd{M-x customize-group RET erc RET}. In particular, ERC comes with | |
340 | lots of modules that may be enabled or disabled; to select which ones | |
341 | you want, do @kbd{M-x customize-variable RET erc-modules RET}. | |

350 | @section Sample Session | |
351 | ||
352 | This is an example ERC session which shows how to connect to the #emacs | |
353 | channel on Freenode. Another IRC channel on Freenode that may be of | |
354 | interest is #erc, which is a channel where ERC users and developers hang | |
355 | out. | |
356 | ||
357 | @itemize @bullet | |
358 | ||
359 | @item Connect to Freenode | |
360 | ||
361 | Run @kbd{M-x erc}. Use ``irc.freenode.net'' as the IRC server, ``6667'' | |
362 | as the port, and choose a nickname. | |
363 | ||
364 | @item Get used to the interface | |
365 | ||
366 | Switch to the ``irc.freenode.net:6667'' buffer, if you're not already | |
367 | there. You will see first some messages about checking for ident, and | |
368 | then a bunch of other messages that describe the current IRC server. | |
369 | ||
370 | @item Join the #emacs channel | |
371 | ||
372 | In that buffer, type ``/join SPC #emacs'' and hit @kbd{RET}. Depending | |
373 | on how you've set up ERC, either a new buffer for ``#emacs'' will be | |
374 | displayed, or a new buffer called ``#emacs'' will be created in the | |
375 | background. If the latter, switch to the ``#emacs'' buffer. You will | |
376 | see the channel topic and a list of the people who are currently on the | |
377 | channel. | |
378 | ||
379 | @item Register your nickname with Freenode | |
380 | ||
381 | If you would like to be able to talk with people privately on the | |
382 | Freenode network, you will have to ``register'' your nickname. To do | |
383 | so, switch to the ``irc.freenode.net:6667'' buffer and type ``/msg | |
384 | NickServ register <password>'', replacing ``<password>'' with your | |
385 | desired password. It should tell you that the operation was successful. | |
386 | ||
387 | @item Talk to people in the channel | |
388 | ||
389 | If you switch back to the ``#emacs'' buffer, you can type a message, and | |
390 | everyone on the channel will see it. | |
391 | ||
392 | @item Open a query buffer to talk to someone | |
393 | ||
394 | If you want to talk with someone in private (this should usually not be | |
395 | done for technical help, only for personal questions), type ``/query | |
396 | <nick>'', replacing ``<nick>'' with the nickname of the person you would | |
397 | like to talk to. Depending on how ERC is set up, you will either see a | |
398 | new buffer with the name of the person, or such a buffer will be created | |
399 | in the background and you will have to switch to it. Begin typing | |
400 | messages, and you will be able to have a conversation. | |
401 | ||
402 | Note that if the other person is not registered, you will not be able to | |
403 | talk with them. | |

409 | @section Special Features | |
410 | ||
411 | ERC has some features that distinguish it from some IRC clients. | |
412 | ||
413 | @itemize @bullet | |
414 | ||
415 | @item multiple channels and multiple servers | |
416 | ||
417 | Every channel is put in a separate buffer. Several IRC servers may be | |
418 | connected to at the same time. | |
419 | ||
420 | @cindex query buffers | |
421 | @item private message separation | |
422 | ||
423 | Private conversations are treated as channels, and are put into separate | |
424 | buffers in Emacs. We call these ``query buffers''. | |
425 | ||
426 | @item highlighting | |
427 | ||
d20cf916 | 428 | Some occurrences of words can be highlighted, which makes it easier to |
4009494e GM |
429 | track different kinds of conversations. |
430 | ||
431 | @item notification | |
432 | ||
433 | ERC can notify you that certain users are online. | |
434 | ||
435 | @item channel tracking | |
436 | ||
437 | Channels can be hidden and conversation continue in the background. You | |
438 | are notified when something is said in such a channel that is not | |
439 | currently visible. This makes it easy to get Real Work done while still | |
440 | maintaining an IRC presence. | |
441 | ||
442 | @item nick completion | |
443 | ||
444 | ERC can complete words upon hitting @kbd{TAB}, which eases the writing | |
445 | of nicknames in messages. | |
446 | ||
447 | @cindex history ring | |
448 | @item history | |
449 | ||
450 | Past actions are kept in history rings for future use. To navigate a | |
451 | history ring, hit @kbd{M-p} to go backwards and @kbd{M-n} to go | |
452 | forwards. | |
453 | ||
454 | @item multiple languages | |
455 | ||
456 | Different channels and servers may have different language encodings. | |
457 | ||
458 | In addition, it is possible to translate the messages that ERC uses into | |
459 | multiple languages. Please contact the developers of ERC at | |
460 | @email{erc-discuss@@gnu.org} if you are interested in helping with the | |
461 | translation effort. | |
462 | ||
463 | @item user scripting | |
464 | ||
465 | Users can load scripts (e.g. auto greeting scripts) when ERC starts up. | |
466 | ||
467 | It is also possible to make custom IRC commands, if you know a little | |
468 | Emacs Lisp. Just make an Emacs Lisp function and call it | |
469 | @code{erc-cmd-NEWCOMMAND}, where @code{NEWCOMMAND} is the name of the | |
470 | new command in capital letters. | |
471 | ||
472 | @item auto reconnect | |
473 | ||
474 | If the connection goes away at some point, ERC will try to reconnect | |
475 | automatically. If it fails to reconnect, and you want to try to | |
476 | manually reestablish the connection at some later point, switch to an | |
477 | ERC buffer and run the @code{/RECONNECT} command. | |

569 | @cindex modules | |
570 | ||
571 | One way to add functionality to ERC is to customize which of its many | |
572 | modules are loaded. | |
573 | ||
574 | There is a spiffy customize interface, which may be reached by typing | |
575 | @kbd{M-x customize-option erc-modules RET}. Alternatively, set | |
576 | @code{erc-modules} manually and then call @code{erc-update-modules}. | |
577 | ||

719 | @cindex connecting | |
720 | ||
721 | The easiest way to connect to an IRC server is to call @kbd{M-x erc}. | |
722 | If you want to assign this function to a keystroke, the following will | |
723 | help you figure out its parameters. | |
724 | ||
725 | @defun erc | |
726 | Select connection parameters and run ERC. | |
727 | Non-interactively, it takes the following keyword arguments. | |
728 | ||
729 | @itemize @bullet | |
730 | @item @var{server} | |
731 | @item @var{port} | |
732 | @item @var{nick} | |
733 | @item @var{password} | |
734 | @item @var{full-name} | |
735 | @end itemize | |
736 | ||
737 | That is, if called with the following arguments, @var{server} and | |
738 | @var{full-name} will be set to those values, whereas | |
739 | @code{erc-compute-port}, @code{erc-compute-nick} and | |
740 | @code{erc-compute-full-name} will be invoked for the values of the other | |
741 | parameters. | |

807 | ||
808 | @defopt erc-nick | |
809 | Nickname to use if one is not provided. | |
810 | ||
811 | This can be either a string, or a list of strings. | |
812 | In the latter case, if the first nick in the list is already in use, | |
813 | other nicks are tried in the list order. | |

991 | @email{sergey.berezin@@cs.cmu.edu}. They stopped development around | |
992 | December 1999. Their last released version was ERC 2.0. | |
993 | ||
994 | P.S.: If one of the original developers of ERC reads this, we'd like to | |
995 | receive additional information for this file and hear comments in | |
996 | general. | |

1001 | In June 2001, Mario Lang @email{mlang@@delysid.org} and Alex Schroeder | |
1002 | @email{alex@@gnu.org} took over development and created a ERC Project at | |
1003 | @uref{http://sourceforge.net/projects/erc}. | |
1004 | ||
1005 | In reaction to a mail about the new ERC development effort, Sergey | |
1006 | Berezin said, ``First of all, I'm glad that my version of ERC is being | |
1007 | used out there. The thing is, I do not have free time and enough | |
1008 | incentive anymore to work on ERC, so I would be happy if you guys take | |
1009 | over the project entirely.'' | |
1010 | ||
1011 | So we happily hacked away on ERC, and soon after (September 2001) | |
1012 | released the next "stable" version, 2.1. | |
1013 | ||
1014 | Most of the development of the new ERC happened on #emacs on | |
1015 | irc.openprojects.net. Over time, many people contributed code, ideas, | |
1016 | bugfixes, and a lot of alpha/beta/gamma testing. | |

1031 | the release manager and eventually the maintainer. | |
1032 | ||
1033 | After some discussion between him and the Emacs developers, it was | |
1034 | decided to include ERC in Emacs. | |
1035 | ||

1037 | ||
1038 | ERC 5.1 was released. It was subsequently included in Emacs 22. | |
1039 | ||
1040 | ERC became an official GNU project, and development moved to | |
1041 | @uref{http://sv.gnu.org/projects/erc}. We switched to using GNU Arch as | |
1042 | our revision control system. Our mailing list address changed as well. | |
