ff59d266 6* Changes in ERC 5.2
83dc6995
MB
7
8** M-x erc RET now starts ERC.
9`erc-select' has been changed to `erc'. `erc-select' still remains as
10an alias of `erc'. Likewise, `erc-select-ssl' has been renamed to
11`erc-ssl' with `erc-select-ssl' as its alias. The function that was
12known as `erc' is now `erc-open'.
13
ff59d266
MB
14** Open query buffers by default when private messages are received.
15The default value of `erc-auto-query' has been changed to 'bury.
16
10dc9f9e
MB
17** New command: /RECONNECT
18This command tries to reconnect to the current IRC server exactly
19once. It does not work in server buffers (throws an error before the
20command is run), but works in query and channel buffers.
21
ff59d266
MB
22** In MS-DOS environments, look for _ercrc.el rather than .ercrc.el.
23
24** Fix buggy interaction with multi-tty Emacs.
25
26** After running /QUIT, make sure that the IRC process is killed within
274 seconds. Freenode, in particular, needs this at times.
28
29** If the IRC process has not responded to our PINGs within a certain
30time, kill it and restart the connection. See
31`erc-server-auto-reconnect', `erc-server-reconnect-attempts',
32`erc-server-reconnect-timeout', `erc-server-send-ping-interval', and
33`erc-server-send-ping-timeout' to fine-tune ERC's behavior.
34
35** Avoid getting into an infinite connection loop.
36Previously, this could happen if your nick was banned, you were using
37Tor, incorrect information was entered, or the connection was bad.
38
39** Make ban messages less confusing.
40
41** Restore the point correctly when reconnecting to an IRC server.
42
43** Make /IGNORE and /UNIGNORE prompt to determine whether their
44argument is a user or a regexp. This results in less-confusing
45behavior when trying to ignore someone who has a bracket in their
46nick.
47
48** Make the default port "6667" rather than "ircd", because some
49operating systems don't know what port "ircd" maps to.
50
51** Fix several bugs in erc-iswitchb (C-c C-b).
52
53** Clean up internal documentation.
54Special thanks go to Juanma Barranquero for the thorough vetting of
55ERC's internal documentation.
56
57** Display a more informative message when a module is not found.
58
59** Fix a bug where paths were being colored like IRC commands.
60
61** In the customize interface for `erc-modules', add the name of the module.
62This makes it easier to find modules by name.
63
64** erc-server-send-ping-interval: Change to use a default of 30 seconds.
65
66** Some files which are included with the release of ERC 5.2 will not
67appear in the version of ERC that is bundled with Emacs 22. These
68extras files may be found at:
69
70 o http://ftp.gnu.org/gnu/erc/erc-5.2-extras.tar.gz, or
71 o http://ftp.gnu.org/gnu/erc/erc-5.2-extras.zip.
72
73** Renamed files
74
75Several files were renamed so as to make them distinct to users of the
76MS-DOS operating system.
77
78 o erc-autojoin.el -> erc-join.el
79 o erc-complete.el -> erc-hecomplete.el
80 o erc-nickserv.el -> erc-services.el
81 o ChangeLog.NNNN -> ChangeLog.NN
82
83** Header line changes
84
85*** Remove "[IRC]" from the header line.
86
87*** Add the %l format character to `erc-header-line-format',
88
89*** Document how to remove the header line.
90Namely: (setq erc-header-line-format nil).
91
10dc9f9e
MB
92** New options
93
94*** erc-server-reconnect-attempts: Determines the number of
95reconnection attempts that ERC will make per server.
96
ff59d266
MB
97*** erc-server-reconnect-timeout: Determines the amount of time,
98in seconds, that ERC will wait between successive reconnect attempts.
99
100*** erc-server-send-ping-timeout: Determines when to consider a connection
101stalled and restart it. The default is after 120 seconds.
102
103*** erc-system-name: Determines the system name to use when logging in.
104The default is to figure this out by calling `system-name'.
10dc9f9e 105
6904f7fe
MB
106** New face: `erc-my-nick-face'
107This helps make it easier to distinguish messages sent by yourself
108from messages sent by other users when the value of the variable
109`erc-show-my-nick' is non-nil.
110
ff59d266
MB
111** Namespace changes
112
113*** New macro: `erc-with-server-buffer'
114Switches to the current ERC server buffer and runs some code. If no
115server buffer is available, return nil. This is a useful way to
116access variables in the server buffer.
117
118*** New function: `erc-open-server-buffer-p'
119Returns non-nil if the given buffer is an ERC server buffer that has
120an open IRC process.
121
122*** New function: `erc-format-lag-time'
123Returns the estimated lag time to server, `erc-server-lag'.
124
125*** Renamed items
126
127 o `erc-server-setup-periodical-server-ping' is now
128 `erc-server-setup-periodical-ping'
129
130 o `erc-away-p' is now `erc-away-time'
131
132** Changes to the ERC manual
133
134*** New section: Sample Session.
135Describes a sample ERC session for connecting to the #emacs channel on
136Freenode. Also mention the #erc channel.
137
138*** New section: Special Features.
139Describes some of the special features of ERC.
140
141*** Getting Started: Mention ~/.emacs.d/.ercrc.el and the Customize
142interface.
143
144*** Development: Mention ErcDevelopment page on emacswiki.org.
145
146*** Tips and Tricks: Remove empty section for now.
147
148*** Options: Mention how to see available ERC options.
149
150*** Sample Configuration: Add an example of how to configure ERC.
151
6904f7fe
MB
152** New modules
153
ff59d266
MB
154*** Autoaway (erc-autoaway.el)
155
156**** Make this much more reliable.
157
158**** Avoid duplicate messages when coming back from being away.
159
160**** Fix bug where autoaway was enabled just by loading the file.
161
162*** BBDB (erc-bbdb.el)
163
164**** Display information on how to cancel merging of info or how to
165create a new John Doe record.
166
167**** Make it so that information from /whois continues to come in, even
168while prompting for a record to merge.
169
170**** Make hitting C-g correctly abort merging the record.
171
6904f7fe
MB
172*** Capab identify (erc-capab.el)
173Mark users who haven't identified to NickServ on servers supporting
174CAPAB IDENTIFY-MSG.
175
83dc6995
MB
176** Changes and additions to modules
177
ff59d266 178*** Button (erc-button.el)
cb0a26d3 179
ff59d266 180**** Make <backtab> go to the previous button.
cb0a26d3 181
83dc6995
MB
182*** Channel tracking (erc-track.el)
183
184**** Use mouse-face and help-echo for channel names in the mode-line.
185This helps people using a mouse know that they are buttons and can be
186clicked on.
187
ff59d266
MB
188**** Fix issue where C-c C-SPC could conflict with user-defined keybindings.
189This is accomplished by moving these bindings to their own global
190minor mode. Now the default is to check whether the user has bound
191something to C-c C-SPC or C-c C-@. If they have, prompt them about
192whether to really override that binding. This also has the effect of
193preventing ERC from clobbering rcirc's keybinding, unless this is
194desired. See `erc-track-enable-keybindings' for more details.
195
196**** New option: erc-track-enable-keybindings.
197Determine whether or not to enable the C-c C-SPC and C-c C-@
198keybindings. The default is to ask whether to do this if a binding to
199these keys already exists. It can also be set to t or nil to always
200bind or never bind, respectively.
201
202**** Remove `track-when-inactive' module.
203See `erc-track-when-inactive' for further details.
204
205**** New option: erc-track-when-inactive.
206This option replaces the track-when-inactive module. Set it to
207non-nil to track activity even in visible buffers when inactive. The
208default is nil.
209
210**** Remove the `track-modified-channels' alias for the `track' module.
211
212*** DCC support (erc-dcc.el)
213
214**** Add Usage section to Commentary.
215
216**** Fix a bug in the server message output.
217
218*** Filling (erc-fill.el)
219
220**** Fix bug involving messages that start with one or more blank lines.
221
222*** Identd (erc-identd.el)
223
224**** New option `erc-identd-port'
225Specifies the port to use if none is given as an argument to
226`erc-identd-start'. This is placed in the new customization group
227`erc-identd'.
228
229**** New function: `erc-identd-quickstart'
230Ignores any arguments and calls `erc-identd-start'.
231
232*** Channel lists (erc-list.el)
233
234**** Enable by default, except in the version of ERC bundled with Emacs 22.
235
236*** Logging (erc-log.el)
237
238**** Make sure filenames are safe to use before writing to them.
239
240**** Save all log buffers when exiting Emacs.
241
242**** erc-generate-log-file-name-function: Add option for
243`erc-generate-log-file-name-network', which is a new function that
244uses the network name rather than the server name when possible.
245
246*** Menu (erc-menu.el)
247
248**** Name the menu "ERC" instead of "IRC" to avoid confusion with rcirc
249and other clients.
250
251**** Make this into a proper module and load it by default.
252
253**** Add "Current channel" submenu.
254
255*** Networks (erc-networks.el)
256
257**** Add support for Ars OpenIRC, LinuxChix, and OFTC networks.
258
259**** Escape periods in Konfido.Net and Kewl.Org.
260
261*** Internet services / Nickserv (erc-nickserv.el)
262
263**** Add new 'both method for the `erc-nickserv-identify-mode' option
264and make it the default. This tries to do the right thing both when a
265known nickserv message exists for an IRC network, and when it does
266not.
267
268**** Support nickserv authentication on OFTC, Azzurra, Ars, and QuakeNet.
269
270**** Support authentication on BitlBee.
271
272**** Make source code easier to understand by using accessor functions.
273
274*** Sound support (erc-sound.el)
275
276**** Make this work with both Emacs 21 and Emacs 22.
277
278*** Timestamps (erc-stamp.el)
279
280**** Exclude the newline from the erc-timestamp field.
281
282**** New function: `erc-toggle-timestamps'.
283Toggles display of timestamps.
284
2e3ef421
MB
285* Changes in ERC 5.1.4
286
287** Make find-function and find-variable work in Emacs 22 for
288names that are constructed by `define-erc-module'.
289
290** Fix bug introduced in ERC 5.1.3 that caused messages to go the
291wrong buffer.
292
293** Changes and additions to modules
294
295*** Highlighting (erc-match.el)
296
297**** Don't activate view-mode.
298
299*** Logging (erc-log.el)
300
301**** When this module is activated, make sure logging is enabled on
302already-opened buffers. Ditto for disabling logging when the module
303is deactivated.
304
305**** Fix some errors that occur when exiting Emacs without first
306quitting open IRC servers.
d8bd1ad4 307
0b6bb130
MB
308* Changes in ERC 5.1.3
309
310** Fix use of /quote command with no initial whitespace.
311
312** Make it possible to customize the colorization of the header line.
313The `erc-header-line' face is used to color the header line.
314The `erc-header-line-face-method' determines the method to use when
315colorizing the header line.
316
317** Add the new function `erc-handle-irc-url', which is a suitable
318candidate to use for `url-irc-function'. This permits some
319integration of url.el and ERC.
320
321** Fix several errors that occur when server or channel buffers are killed
322prematurely.
323
324** Fix toggling of flood control.
325
326** Match the patterns in `erc-encoding-coding-alist' as regexps,
327instead of verbatim text. Also, match case-insensitively.
328
329** The /SMV command has been removed, since we no longer have
330meaningful module-specific version information.
331
332** Fix a "(stringp nil)" error that can happen when doing /PART.
333
334** Use a better example in the `erc-part-reason-various-alist'
335documentation.
336
337** When using `erc-quit-reason-various' and `erc-part-reason-various'
338and no matches are found, default to using the ERC version string
339rather than "nil".
340
341** Add the `list' and `page' modules to the `erc-modules' customize
342interface.
343
344** Changes to the ERC manual
345
346*** Update the list of available modules.
347
348*** Revise information about releases and development.
349
350*** Provide a simpler example in the "Getting Started" chapter.
351
352*** Fully document how to connect to an IRC server in the new
353"Connecting" chapter.
354
355** Changes and additions to modules
356
357*** Autoaway (erc-autoaway.el)
358
359**** Rename the `erc-autoaway-use-emacs-idle' option to
360`erc-autoaway-idle-method'.
361
362**** Add support for autoaway based on user idle time.
363This is now the default.
364
365**** If you set the AWAY status yourself, erc-autoaway will not
366interfere by un-setting AWAY prematurely.
367
368**** If you are set away while visiting a non-ERC buffer,
369erc-autoaway used to fail in bringing the user back. This is now
370fixed.
371
372*** BBDB (erc-bbdb.el)
373
374**** Add new option `erc-bbdb-electric-p', which determines whether
375to make the BBDB buffer electric. This defaults to not electric.
376
377*** Button (erc-button.el)
378
379**** Use <backtab> instead of <C-tab> for `erc-button-previous'.
380
381*** Identd (erc-identd.el)
382
383**** Fix a bug that involves starting the identd server.
384
385**** Make this work with Emacs 22.
386
387**** Provide a real ERC module named `identd'.
388
389**** Don't create an extra buffer for the identd process.
390
ff59d266
MB
391*** Channel lists (erc-list.el)
392
393**** Enable by default, except in the version of ERC bundled with Emacs 22.
394
0b6bb130
MB
395*** Logging (erc-log.el)
396
397**** By default, don't insert old logs when opening an ERC buffer.
398This may be changed by customizing `erc-log-insert-log-on-open'.
399
400**** New option `erc-log-write-after-send' determines whether the
401log file will be written to after every sent message. The default is
402not to do this.
403
404**** New option `erc-log-write-after-insert' determines whether the
405log file will be written to when new text is added to a logged ERC
406buffer. The default is not to do this. With this option and the
407previous option, logging should no longer slow down ERC as much.
408
409**** Default to saving buffers and queries on quit.
410This may be changed by customizing the `erc-save-buffer-on-quit' and
411`erc-save-queries-on-quit' options, respectively.
412
413**** Only perform logging when the `logging' module is added to
414`erc-modules'. This prevents logging from being activated just by
415loading the erc-log.el file, and makes logging act like other ERC
416modules.
417
418*** Programmable completion (erc-pcomplete.el)
419
420**** Don't complete the user's current nickname.
421
d8bd1ad4 422* Changes in ERC 5.1.2
e7559e30
MB
423
424** Fix compiler errors in erc-autojoin.el and erc-dcc.el.
425
426** Move to end of prompt when ERC reconnects to a server.
427
428** Changes and additions to modules
429
430*** Spell-checking (erc-spelling.el)
431
432**** Don't spell-check nicks or words that are prefixed with '/'.
433
434**** Remove flyspell properties from words we shouldn't spell-check.
435
436**** Fix an issue that caused the ispell process to reload every time
437we switch to an ERC buffer.
438
439*** Timestamps (erc-stamp.el)
440
441**** Fix an inconsistency in calculating width of right timestamps.
442
443**** Rename option `erc-timestamp-right-align-by-pixel' to
444`erc-timestamp-use-align-to'. This controls whether to use the more
445fail-proof method of aligning right timestamps, as mentioned below.
446
447**** Fix a right timestamp spacing problem that used to occur when
448erc-stamp.el was byte-compiled. Now that this is fixed, it is safe to
449use the method that aligns right timestamps perfectly in Emacs22 with
450X. If the current version of Emacs doesn't support this method, use
451the simpler method, which is prone to alignment issues for math
452symbols and other variable-width text.
453
454A side effect of using this new method is that there will only be one
455space before a right timestamp in any saved logs. If this is
456unacceptable, set `erc-timestamp-use-align-to' to nil.
457
8508e990
MB
458* Changes in ERC 5.1.1
459
460** Fix a requirement on cl.el.
461
462** Use tls.el for SSL connections, rather than ssl.el.
463
464** Changes and additions to modules
465
466*** ibuffer integration (erc-ibuffer.el)
467
468**** Update this to work with the version of ibuffer.el that comes with
469recent Emacs variants.
470
471*** Old completion (erc-complete.el)
472
473**** Fix a few errors.
474
475*** Speedbar (erc-speedbar.el)
476
477**** Make this work with the version of speedbar.el that comes with
478recent Emacs variants.
479
480*** Timestamps (erc-stamp.el)
481
482**** By default, use a more failsafe method of displaying right timestamps.
483To get right timestamps to align perfectly in Emacs22 using X, set the
484new `erc-timestamp-right-align-by-pixel' option to non-nil.
485
486*** Viper compatibility (erc-viper.el)
487
488**** Since most of these changes are now merged into Emacs22, detect
489whether we need these changes and install them only if necessary.
490
491* Changes in ERC 5.1
597993cf
MB
492
493** Improve XEmacs compatibility.
494
495** Namespace changes

515
516** Bugfixes
517
518*** Don't inadvertently destroy face properties.
519
520*** Load erc scripts in a safer way.
521
522*** Don't insert a timestamp if text at point is invisible.
523
524*** Don't hide messages from those in `erc-fools' by default.
525Color their nicks instead.
526
527*** Use a more foolproof method of encoding and decoding strings
528before sending to a channel.
529
530** Backend changes

557
558*** Renamed some functions
559

575 o erc-server-flood-margin, erc-server-flood-penalty: New options
576 that allow tweaking of flood control.
577
578 o erc-split-line-length: The maximum line length of a single
579 message.
580
581*** New variables
582
583 o erc-server-flood-last-message, erc-server-flood-queue,
584 erc-server-flood-timer: Flood control.
585
586 o erc-server-processing-p: Indicate when we're currently processing
587 a message.
588
589*** Remove some options
590
591 o `erc-flood-limit'
592 o `erc-flood-limit2'
593
594** New customization group `erc-server' for dealing with IRC servers.
595
596** ERC can now be installed by doing `make install' from the command line.
597
598** ERC now has a manual in erc.texi.
599Type `make doc' to generate HTML and Info versions of it.
600
601** ERC no longer depends on cl.el.
602Only the macros in cl-macs.el are used.
603
604** Fix an edge case when quitting as new messages come in.
605
606** Make flood protection toggle-able as on/off, removing the 'strict option.
607
608** If possible, re-use channel buffers when reconnecting to a server.
609
610** Text in ERC buffers is now read-only by default.
611To get the previous behavior,
612
613** Changes and additions to modules
614
615*** Auto-join (erc-autojoin.el)
616
617**** Recognize the Azzurra server.
618
619*** BBDB (erc-bbdb.el)
620
621**** When the user types /WHOIS, ask for a record to merge to.
622
623**** Store the displayed name of a BitlBee contact.
624The new `erc-bbdb-bitlbee-name-field' option specifies the field to use
625to store this information.
626
627**** Don't prompt for a name on /JOIN or /NICK.
628
629*** Button (erc-button.el)
630
631**** Fix customization of `erc-button-alist'
632
633**** New option `erc-button-nickname-face' determines the face to use
634when coloring ERC nicknames.
635
636*** Channel tracking (erc-track.el)
637
638**** Remove channels from the modified channels list if not currently
639connected. This should remove residue from the mode line after
640quitting ERC.
641
642**** Recognize buttonized text
643
644*** Highlighting (erc-match.el)
645
646**** Highlight current nickname by default.
647
648**** Added the option of beeping when certain matches occur.
649Add `erc-beep-on-match' to `erc-text-matched-hook' to enable
650beeping. Set the new variable `erc-beep-match-types' which match
651types that make beeps.
652
653*** Nicklist (erc-nicklist.el)
654
655**** Fix a couple of errors.
656
657**** Make sure a stray mouse click doesn't trigger an error.
658
659**** Insert icons from the /images directory next to nicks.
660This indicates their away status. The location is customizable via
661the new `erc-nicklist-icons-directory' option.
662
663If you do not want these icons, set `erc-nicklist-use-icons' to nil.
664
665*** Nickserv identification (erc-nickserv.el)
666
667**** Recognize Azzurra and OFTC networks.
668
669*** Old completion (erc-complete.el)
670
671**** Disable by default.
672
673*** Programmable completion (erc-pcomplete.el)
674
675**** Enable by default.
676
677*** Timestamps (erc-stamp.el)
678
679**** On Emacs22, align right timestamps perfectly, even if variable-width
680characters are used. If we aren't using Emacs22, move text farther
681away from the right margin when variable-width characters are used.
682It is considered better to misalign the stamp by a bit than to go past
683the right margin.
684
685**** Enable by default
686
687** New modules
688
689*** Spell-checking (erc-spelling.el)
690
691**** Use flyspell in ERC.
692
693*** Viper compatibility (erc-viper.el)
694
695**** Helps ERC work correctly in viper-mode.
696

698
699** Fix a problem with undo in channels.
700
8508e990 701* Changes in ERC 5.0.3
597993cf
MB
702
703** Fix typo in the `ctcp-request-to' entry of the English catalog.
704
705** Debugging with edegug has been made easier in all of the
706erc-with-* and with-erc* macros.
707
708** Non-ASCII character sets should be better supported when sending
709and processing messages.
710
711** A load failure with erc-autoaway.el and Emacs21 has been fixed.
712
713** A few XEmacs warnings were fixed.
714
715** Changes and additions to modules
716
717*** Backend (erc-backend.el)
718
719**** Move the check for hidden messages into `erc-display-message'
720so there isn't so much replicated code.
721
722**** Add `definition-name' property to constructed symbols so that
723`find-function' and `find-variable' will be able to locate them.
724
725**** Make sure logs are inserted info the correct channel buffers.
726There was previously an error when using `erc-insert-log-on-open' in
727combination with autojoin to multiple channels.
728
729*** Button (erc-button.el)
730
731**** The layering of `erc-button-face' on other faces in ERC buffers
732has been improved.
733
734*** Channel tracking (erc-track.el)
735
736**** Use optimal amount of whitespace around modified channels
737indicator. Previously, there was an additional unnecessary space.
738
739**** Fix an error that occurred when unchecked buffers existed when
740invoking /QUIT.
741
8508e990 742* Changes in ERC 5.0.2
597993cf
MB
743
744** If a channel key is required for a certain channel, ERC will prompt
745for one if `erc-prompt-for-channel-key' is non-nil.
746
747** ERC doesn't try to reconnect if the network connection is refused
748when using `open-network-stream-nowait' as the `erc-connect-function'.
749
750** Messages from multiple servers will not go to the currently active
751buffer. The messages from each server will be contained in the most
752recently active channel/server buffer that corresponds with the
753server.
754
755** Some text messages were cleaned up slightly.
756
757** Button faces should no longer "cover" other faces.
758
759** Made some XEmacs compatibility fixes.
760
761** Nicknames containing a backslash are now correctly highlighted as
762current-nick and buttonized as nicks.
763
764** `erc-server-select' doesn't offer networks without servers as a
765choice anymore.
766
767** Non-ASCII character support has been improved.
768
769** Changes and additions to modules
770
771*** Menu (erc-menu.el)
772
773**** You can now save logs and truncate buffers from the menu-bar.
774
8508e990 775* Changes in ERC 5.0.1
597993cf
MB
776
777** Narrowing in ERC buffers no longer causes formatting errors.
778
779** The BBDB module now loads correctly when customizing `erc-modules'.
780
781** The value of `erc-button-face' is now respected.
782
783** Fixed a bug which caused a read-only error during connection.
784
785** Server buffers are now tracked correctly.
786This means that `erc-track-priority-faces-only', `erc-track-exclude',
787and `erc-track-exclude-types' now work with server buffers.
788
8508e990 789* Changes in ERC 5.0
597993cf
MB
790
791** Channel members are now stored as a hash-table.
792`erc-server-users' and `erc-channel-users' are now hash-tables, rather
793than alists. This significantly increases performance, especially in
794large channels. Each channel member is stored as an `erc-server-user'
795struct, with additional information about the channels they are on
796stored in an `erc-channel-user' struct. Code using old alist-style
797channel members needs to be updated to work with hash-tables.
798This new code also removes the need for erc-members.el, which has been
799removed.
800
801** The way ERC deals with input from the server has changed.
802All server response code is now in a new file, erc-backend.el. There
803should be no real user visible changes. There are, however, a few
804major changes for implementers, and module writers:
805
806*** The PARSED response that all handlers get called with is
807 no longer a vector, but an `erc-response' struct.
808
809 This means LESS MAGIC NUMBERS in the ERC source code, but a few
810 changes in how you get at parsed responses.
811
812 The sender is accessed via `erc-response.sender'.
813
814 The command is accessed via `erc-response.command'.
815
816 The arguments to the command (everything after the command and
817 before the colon) are accessed via `erc-response.command-args'.
818 This is a /list/ of arguments in the order they appear in the
819 unparsed response.
820
821 The contents of the response is accessed via
822 `erc-response.contents'.
823
824 Should, for some reason, you want to do something with the
825 /unparsed/ response, you can get it via `erc-response.unparsed'.
826
827*** The `erc-server-hook-list' mechanism is gone.
828
829 All server response handlers should be defined with
830 `define-erc-response-handler'. This defines functions and
831 corresponding hook variables.
832
833 The mapping of server commands to hook variables is no longer
834 done via `erc-event-to-hook', but through an #'equal hashtable,
835 `erc-server-responses'. In order to find a hook you do:
836
837 (erc-get-hook command)
838
839 See the docstring of `define-erc-response-handler' for more
840 information.
841
842*** ALL hook variables have been renamed.
843
844 In accordance with recommendations in the Emacs Lisp manual,
845 the hook variables are no longer called `erc-server-FOO-hook',
846 but rather `erc-server-FOO-functions'. This is to indicate
847 that the functions they call take arguments.
848
849 All the modules in ERC have been updated to reflect this change,
850 but external module authors should beware.
851
852** The values of `erc-mode-line-format' and `erc-header-line-format'
853are now defined as strings to be formatted using `format-spec'.
854`erc-mode-line-format' does not replace the whole mode-line anymore,
855only `mode-line-buffer-identification' is set. This way, personal
856mode-line configurations are not modified and all key bindings work as
857expected. The process status (connecting, closed) is now shown in
858`mode-line-process'.
859
860** Customization of ERC variables has been made easier. Variables
861have been split into more groups for better organization.
862
863** New variables
864
865 o `erc-send-whitespace-lines' - Set this to send lines even if they
866 are empty.
867
868 o `erc-manual-set-nick-on-bad-nick-p' - If the nickname you chose is
869 already taken or not allowed, your nick is not changed and you can
870 try again manually if this is non-nil.
871
872 o `erc-mode-line-away-status-format' - You can now set what is shown
873 in the mode-line when you are away.
874
875 o `erc-header-line-uses-help-echo-p' - The header-line now uses the
876 help-echo property. You can set this to nil to disable it.
877
878 o `erc-format-query-as-channel-p' - Set this to nil to have messages
879 in the query buffer formatted like private messages.
880
881 o `erc-show-channel-key-p' - The channel key is now shown with the
882 other channel modes in the header line. Set this to nil if you
883 want it hidden.
884
885 o `erc-prompt-for-channel-key' - Set this if you want to be prompted
886 for the channel key (channel's mode is +k) when you call
887 `erc-join-channel' interactively.
888
889 o `erc-kill-server-buffer-on-quit' - If non-nil, kill the server
890 buffer automatically when you quit.
891
892** New hooks
893
894 o `erc-join-hook' - Called when you join a channel.
895
896 o `erc-kick-hook' - Called when you are kicked from a channel. The
897 channel's buffer is sent as an argument to functions called from
898 this hook.
899
900 o `erc-nick-changed-functions' - Whenever your nickname changes
901 successfully, the functions in this hook are run with the
902 arguments NEW-NICK and OLD-NICK.
903
904** New command /WHOAMI - Do a /WHOIS on your current nickname.
905
906** The key binding for changing channel modes is now C-c C-o.
907
908** Removed variables
909
910 o `erc-echo-notices-in-minibuffer-flag' and
911 `erc-echo-notices-in-current-buffer' - You should use
912 `erc-echo-notice-hook' and `erc-echo-notice-always-hook' instead.
913
914 o `erc-prompt-interactive-input' has been removed (commented out)
915 because nickname completion does not work with it.
916
917 o All INFO buffer-related variables and functions have been removed.
918
919** You can now disable modules by setting `erc-modules' with the
920customization interface.
921
922** Changes and additions to modules
923
924*** Autoaway (erc-autoaway.el)
925
926**** New variable `erc-autoaway-no-auto-back-regexp' - Add text which,
927when you type anything matching it, will not automatically discard
928your away status when `erc-auto-discard-away' is non-nil.
929
930*** Filling (erc-fill.el)
931
932**** New variable `erc-fill-variable-maximum-indentation' - Don't
933indent more than this many characters when indenting a message from a
934user with a long nickname.
935
936*** Goodies (erc-goodies.el)
937
938**** Miscellaneous small modules have been moved from erc.el.
939The functions erc-add-scroll-to-bottom, erc-make-read-only,
940erc-send-distinguish-noncommands, erc-interpret-controls, erc-unmorse,
941erc-smiley, and erc-occur, which were defined in the main erc.el file
942have been moved to erc-goodies.el and have mostly been translated to
943the modules scrolltobottom, readonly, noncommands, irccontrols, smiley
944and unmorse.
945
946**** New variables
947
948 o `erc-input-line-position' - The line number to use with
949 `erc-scroll-to-bottom'.
950
951 o `erc-beep-p' - Beep if there is a \C-g control character in a
952 message.
953
954*** Channel lists (erc-list.el)
955
956**** New variable `erc-chanlist-highlight-face' - A face used for
957highlighting the current line.
958
959*** Highlighting (erc-match.el)
960
961**** `erc-current-nick-highlight-type' has new options: 'keyword and
962'nick-or-keyword.
963
964*** Menu (erc-menu.el)
965
966**** The `IRC' menu is now automatically added to `erc-mode' buffers.
967
968*** Networks (erc-nets.el)
969
970**** The functions for determining current network are in this file.
971There were a couple of functions spread about in different files which
972each had a different way of determining the current network. The
973methods have been combined, and the big list of known networks
974(`erc-networks-alist') is being put to use. You can access the
975network's name by calling the new function `erc-network'. This
976returns the name of the current network as a symbol or 'Unknown if it
977could not determine which network it is.
978
979*** Nicklist (erc-nicklist.el)
980
981**** ERC has a new way of displaying nicknames in a channel.
982The new file erc-nicklist.el defines a new command `erc-nicklist'
983which pops up a small Emacs window showing the nicknames of all
984members of the current channel. The implementation is not complete
985and is rather proof-of-concept for now. The result is something a bit
986like erc-speedbar, but not quite as invasive, and doesn't require use
987of a new frame.
988
989*** Internet services / Nickserv (erc-nickserv.el)
990
991**** Network detection is now taken care of by erc-nets.el.
992The function `erc-current-network' is deprecated, use `erc-network'
993instead. The variable `erc-networks' has been removed, use
994`erc-networks-alist'. The network symbols used in
995`erc-nickserv-alist' now match those in `erc-networks-alist'.
996
997**** New variable `erc-nickserv-identify-mode' - Choose which method
998to use for automatic identification: you can wait for Nickserv to ask
999you to identify (the default), or send an identify message
1000automatically after you change your nickname.
1001
1002*** Speedbar (erc-speedbar.el)
1003
1004**** New variable `erc-speedbar-sort-users-type' - Sort users in a
1005channel by activity, alphabetically, or not at all.
1006
1007*** Timestamps (erc-stamp.el)
1008
1009**** `erc-timestamp-only-if-changed-flag' now works when
1010`erc-insert-timestamp-function' is set to 'erc-insert-timestamp-left.
1011
1012**** New variable `erc-timestamp-intangible' - Set this to nil if
1013timestamps should not have the 'intangible property.
1014
1015*** Channel tracking (erc-track.el)
1016
1017**** Using faces to indicate channel activity in the modeline now works
1018in XEmacs.
1019
1020**** New variables
1021
1022 o `erc-track-priority-faces-only' - Ignore changes in a channel
1023 unless there is a face from the `erc-track-faces-priority-list' in
1024 the message.
1025
1026 o `erc-track-exclude-server-buffer' - Ignore changes in the server
1027 buffer.
1028
1029 o `erc-track-position-in-mode-line' - Set the position in the
1030 mode-line where modified channels are shown (only works in GNU
1031 Emacs versions above 21.3).
1032
8508e990 1033* Changes in ERC 4.0
597993cf
MB
1034
1035** The module system has again changed a lot. You can now customize
1036 the variable `erc-modules' and define once and for all which
1037 extension modules you want to use. This unfortunately may require
1038 you to change your current erc initialisation code a bit, if you
1039 have some existing customsations. On the other hand, this change
1040 makes the configuration of extension modules a lot easier for new
1041 users. In theory, you should be able to configure all aspects of
1042 ERC by using the customize interface, you should no longer really
1043 need to write Lisp code for trivial customizations.
1044
1045 By default, the following modules are now loaded: (pcomplete
1046 netsplit fill track ring button autojoin)
1047
1048 Please use M-x customize-variable RET erc-modules RET to change the
1049 default if it does not suite your needs.
1050
1051** THe symbol used in `erc-nickserv-passwords' for debian.org IRC servers
1052 (formerly called OpenProjects, now FreeNode) has changed from
1053 openprojects to freenode. You may need to update your configuration
1054 for a successful automatic nickserv identification.
1055
8508e990 1056* Changes in ERC 3.0.cvs.20030119
597993cf
MB
1057
1058** New module erc-dcc:
1059
1060This finally implements DCC. It requires server sockets to fully work
1061in both directions. This feature is currently only available in Emacs
106221.3.50 (CVS). Here is a short list of what should work though.
1063
1064** Compatibility:
1065 * Emacs 21.2, DCC get, and accepting DCC chat offers.
1066 * XEmacs 21, Only accepting DCC chat offers.
1067
1068** erc is switching to global-minor-modes for activation of submodules.
1069
1070This allows you to customize such a mode and get automatic loading of
1071the module. No longer putting a lot of require statments in .emacs.
1072At least this is the long-term plan, not all modules are converted
1073yet.
1074
1075** The most important user visible change is that you now need to activate
1076erc-completion-mode, to get TAB completion. The new completion code
1077is based on pcomplete. To get the old code, manually load
1078erc-complete and bind TAB to erc-complete in erc-mode-map.
1079
1080To activate completion on startup, put (erc-completion-mode 1) in your
1081.emacs file.
1082
1083Same applies to timestamps. You no longer need to (require
1084'erc-stamp), you can customize the variable `erc-timestamp-mode', and
1085the rest should be automatic.
