1 2006-08-31 Giuseppe Bilotta <giuseppe.bilotta@gmail.com>
3 * Nickserv plugin: bot will now try to inform nickserv when password
4 is changed. Moreover it's not necessary to specify the nick anymore if
5 you want to change the password for the current bot nick. Also do some
6 internal cleanups while we're at it.
8 2006-08-29 Giuseppe Bilotta <giuseppe.bilotta@gmail.com>
10 * Script plugin: new (UNSAFE!) echo functions. Just like eval, but
11 m.replies the result of the evaluation.
12 * New Auth Framework: config keys now have their own permissions. So
13 you can allow people to view or edit only some of the config values.
14 auth.password defaults to false. Still needs some work.
16 2006-08-26 Giuseppe Bilotta <giuseppe.bilotta@gmail.com>
18 * Plugin message mapper: new implementation. Multi-word parameters now
19 need not be the last, and it is possible to retrieve the entire
20 substring with preserved whitespace by using to_s. Also, parts of the
21 map string can be bracketed to make them optional. Examples:
22 remind :user [about] *stuff
24 remind me about washing my teeth
26 remind me washing my teeth
27 It is possible to have parameters in brackets, in which case they will
28 be optional too, and default to nil or [] (resp. single- and
29 multi-word parameters) unless an alternative is provided in the
30 :defaults hash for the message map options.
31 * Script plugin: new (UNSAFE!) eval function. Not documented in help.
32 Not permitted by default.
34 2006-08-25 Mark Kretschmann <markey@web.de>
36 * Added quiz plugin, a multiplayer trivia quiz game.
38 2006-08-20 Giuseppe Bilotta <giuseppe.bilotta@gmail.com>
40 * Topic plugin: fix a bug that prevented it from loading
42 * New IRC Framework: make sure that NOTICEs and PRIVMSGs do not
43 raise an exception when the target is in one of the special forms
44 #<mask> or $<mask>. Needs some work, though, since this case should be
47 2006-08-17 Giuseppe Bilotta <giuseppe.bilotta@gmail.com>
49 * Fix help: It got broken while rearranging the plugin stuff, now it's
51 * New Auth Framework: forgot to create the InvalidPassword exception.
52 It's a RuntimeError now.
53 * Fix help: this time for real (or so I hope).
54 * New IRC Framework: topic plugin now works correctly.
55 * New Auth Framework: nickserv plugin now defaults to false for its
56 auth, so that only owner can do stuff with it
57 * New Auth Framework: fix horrible typo, assignment instead of
58 equality test when checking for the username during login.
59 * Keywords plugin: tell and forget work again without 'keyword' before
62 2006-08-12 Giuseppe Bilotta <giuseppe.bilotta@gmail.com>
64 * Subregistry: force prefix to be a String with to_s
66 2006-08-11 Giuseppe Bilotta <giuseppe.bilotta@gmail.com>
68 * AutoOp plugin: adapted to the new IRC framework.
69 * AutoOp plugin: trigger autoop on nick change too.
70 * New Auth Framework: allow? method now informs a user when they don't
71 have permission to do what they asked for.
72 * New nickreply and nickokay methods: they act like the old reply
73 method, but include the nick of the user the bot is replying to when
74 talking in public. The usual reply method can be configured to act
77 2006-08-10 Giuseppe Bilotta <giuseppe.bilotta@gmail.com>
79 * Fix a bug in new IRC Framework: the list of channels a quitting user was
80 on was not built correctly, causing an exception when the user was not
81 in the first channel in the list of channels.
82 * Fix a bug in new Auth Framework: BotUser's name is changed via
84 * New HalfLife 2 plugin from ocr: queries online servers for online
85 status and number of users.
87 2006-08-07 Giuseppe Bilotta <giuseppe.bilotta@gmail.com>
89 * Add kick method to kernel: plugins can now use
90 @bot.kick channel, user, reason
91 to kick a user from a channel
92 * RSS plugin: fix rewatch_rss method
93 * RSS plugin: the different ways to represent channels before and
94 after the New IRC Framework was causing strange problems such as
95 watched feed not being listed as such, undeletable watches, double
96 watches etc. Fix this by checking both for the Channel objects and
97 their to_s form when checking for watches or deleting them.
99 2006-08-06 Giuseppe Bilotta <giuseppe.bilotta@gmail.com>
101 * Updating the ChangeLog again: describe the new stuff in trunk which
102 will be made available in the next release. Use Gnu style for new
103 changelog entries (yyyy-mm-dd name <email address>\n<tab> ...):
104 there's a macro for this since at least Vim 6.x and higher, called by
105 <Leader>o (default leader: slash (\))
106 * New IRC Framework: Server, Channels, User, Netmasks etc are all
107 proper Ruby objects. The better organization will allow multi-server
108 connections to be implemented more easily
109 * Modularize core: split the internal functionality from what can be
110 implemented as botmodules (which work just the same as plugins). Move
111 Configuration, Basics and Auth out of the 'kernel' into core
113 * New Auth Framework: BotUsers are now Ruby objects with attached
114 PermissionSets which define what the BotUser can do, by channel if
115 necessary. The new framework allows very fine-grained control while
116 still being very easy to manage for elementary usage. BotUser data can
117 be exported and imported, but no backwards compatibility has been
118 implemented yet. Most plugins still have to be updated to the new
119 command-path-based mechanism.
121 Sun Aug 06 17:33:55 BST 2006 Tom Gilbert <tom@linuxbrit.co.uk>
124 * Changes: Lots of new and updated plugins, including one to poll RSS feeds.
125 A first step towards a better auth system (total revamp due in 0.9.11).
126 Improvements to network and server code which should provide greater
127 stability. A new message queueing mechanism with bitrate throttling. A new
128 logging framework for debugging and tracing the activities of the bot. A
129 new split-db registry system for better performance and transactional
130 usage of bdb for resilience. More integration with Nickserv where
131 available including optional automatic ghost-killing.
133 Wed Sep 07 20:16:46 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
135 * Fixed quit, broke it last commit
136 * Fixed trap() for win32
138 Sun Aug 21 13:29:55 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
140 * fix for bug in quakenet plugin (trac #14)
141 * multiple fixes for unescaped bot nick in regexp's (trac #13)
143 Fri Aug 12 20:51:38 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
145 * fix up autoop plugin a bit
147 Thu Aug 11 00:13:11 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
149 * Added two plugins from Robin Kearney <robin@riviera.org.uk>
150 * Threat (US threat level :P)
151 * bash (bash.org quotes)
153 Thu Aug 11 00:04:31 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
155 * Patches from "Alexey I. Froloff" <raorn@altlinux.ru>
156 * Do not use "/home/#{Etc.getlogin}/" for default home directory, use
157 "#{Etc.getpwnam(Etc.getlogin).dir}/" instead.
158 * Do not try to load same plugin from different locations. Added ability
159 to disable system-wide plugins - create PLUGIN.rb.disabled in user's
161 * For example, to disable freshmeat plugin installed in /usr/share/rbot/plugins/freshmeat.rb one can create empty file ~/.rbot/plugins/freshmeat.rb.disabled
163 Mon Aug 08 23:08:01 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
165 * new markov plugin for random inane chat
167 Sun Aug 07 18:20:24 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
169 * stop insult plugin being used to insult the bot
171 Sun Aug 07 17:53:06 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
173 * workaround for people without YAML::load_file
174 * quit message for restart
176 Sun Aug 07 15:11:07 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
178 * fix address_prefix, broken in 0.9.9, reported by ruskie.
180 Sat Aug 06 00:54:34 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
184 Fri Aug 05 23:55:20 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
186 * few more tweaks preparing to release 0.9.9
188 Thu Aug 04 23:03:30 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
190 * Improved ircd recognition of rfc2812.rb
191 * de-string'd, de-cap'd rfc2812.rb, looks less shouty now
192 * moved the Q auth stuff (for quakenet) into a new qauth plugin (untested!)
193 * finish fixing the httputil
195 Thu Aug 04 00:11:52 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
197 * Tweaked the debug() stuff a bit. Need to do this more cleanly really
198 * Added a fair bit of documentation for some of the new features
200 Wed Aug 03 15:25:07 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
202 * Added french language file (TODO most of the plugins just talk english)
203 * The way the Enum configs were set up, it wasn't possible to add language
204 files to rbot at runtime (the directory was only scanned at startup). Now
205 you can set a values Proc, which is called to return a list of allowed
206 values whenever it's queried.
207 * Added Config module for determining where we were installed.
208 Unfortunately rubygems is a total whore in this regard, and I hope the
209 current hackery I have to do to support it becomes redundant in the
212 Wed Aug 03 00:31:41 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
214 * Added Rakefile, tweaked gemspec
216 Tue Aug 02 16:27:36 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
218 * Fixed the new http.proxy* settings, they work!
219 * Fixed a bug with auth-checking for the config module
222 Sun Jul 31 02:20:08 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
224 * Updated docgen to generate rdoc again with the new repo structure
225 * added new restart command to the core bot, quits irc and reexecs the
226 bot, to pick up new code/libraries etc.
228 Sat Jul 30 22:33:36 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
230 * Config items are now objects, various types are available.
231 * The config wizard will now use registered config items if :wizard is set
232 to true for those items. It will ask questions in the order they were
234 * The config module now works for doing runtime configuration.
237 Sat Jul 30 01:19:32 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
239 * config module for configuring the running bot via IRC
240 * BotConfig.register method for various modules and any plugin to register
241 bot configuration which the new config module will expose for them.
242 * various other tweaks as I continue to refactor..
244 Fri Jul 29 13:07:56 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
246 * Moved some stuff out of util.rb into the plugins that actually need
247 them. Those methods didn't belong in util as they were plugin-specific.
248 * moved a few more plugins to use map() where appropriate
249 * made the url plugin only store unique urls
251 Thu Jul 28 23:45:26 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
253 * Reworked the Timer module. The Timer now has a smart thread manager to
254 start/stop the tick() thread. This means the timer isn't called every 0.1
255 seconds to see what needs doing, which is much more efficient
256 * reworked the ircsocket queue mechanism to use a Timer
257 * reworked the nickserv plugin to use maps
258 * made server.reconnect_wait configurable
259 * added Class tracing mechanism to bin/rbot, use --trace Classname for
262 Tue Jul 26 14:41:34 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
264 * Prevent multiple plugin registrations of the same name
265 * reworking the config system to use yaml for persistence
266 * reworking the config system key names
267 * on first startup, the bot will prompt for the essential startup config
268 * new config module for configuring the bot at runtime
269 * new config module includes new configurables, for example changing the
270 bot's language at runtime.
271 * various other fixes
272 * New way of mapping plugins to strings, using maps. These may be
273 familiar to rails users. This is to reduce the amount of regexps plugins
274 currently need to do to parse arguments. The old method (privmsg) is still
275 supported, of course. Example plugin now:
276 def MyPlugin < Plugin
281 def complexfoo(m, params)
282 m.reply "qux! (#{params[:bar]} #{params[:baz]})"
285 plugin = MyPlugin.new
289 # this will match "rbot: foo somestring otherstring" and pass the
290 # parameters as a hash using the names in the map.
291 plugin.map 'foo :bar :baz', :action => 'complexfoo'
292 # this means :foo is an optional parameter
293 plugin.map 'foo :foo', :defaults => {:foo => 'bar'}
294 # you can also gobble up into an array
295 plugin.map 'foo *bar' # params[:bar] will be an array of string elements
296 # and you can validate, here the first param must be a number
297 plugin.map 'foo :bar', :requirements => {:foo => /^\d+$/}
300 Sat Jul 23 01:39:08 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
302 * Changed BotConfig to use yaml storage, method syntax instead of hash for
303 get/set, to allow more flexibility and encapsulation
304 * Added convenience method Message.okay (m.okay is the same as the
305 old-style @bot.okay m.replyto)
307 Wed Jul 20 23:30:01 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
309 * Move some core plugins to use the new httputil
310 * fix wserver's redirection handling for relative (i.e. broken) redirects
311 * fix tube plugin's html parsing
313 Wed Jul 20 01:18:06 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
315 * Add new httputil object to the bot object, to be used by plugins etc
316 that wish to make http requests. It sets up all the proxies etc for them
317 according to bot config.
319 Sat Jul 16 02:23:13 BST 2005 Tom Gilbert <tom@linuxbrit.co.uk>
321 * Apply most of Rene's patch and fix various plugins.
322 * New plugin: autoop (auto ops via hostmask)
323 * New feature: karmastats
325 Wed Oct 13 16:16:31 BST 2004 Tom Gilbert <tom@linuxbrit.co.uk>
327 * Fix bug with quotes plugin where it gets confused and sees both a quote
328 and a keyword, both plugins are triggered by, for example "addquote foo is
330 * fixed this by implementing the "has_responded" flag on a message. When a
331 plugin replied to a message (or it manually sets m.replied to true), the
332 keywords plugin will honour that flag and not examine the message for
333 keywords. This flag can also be checked by listen plugins that don't want to
334 interfere with other plugin commands.
336 Mon Oct 11 00:37:52 BST 2004 Tom Gilbert <tom@linuxbrit.co.uk>
338 * Fixes to the NickServ plugin
340 Sat Oct 09 23:23:24 BST 2004 Tom Gilbert <tom@linuxbrit.co.uk>
344 Fri Oct 08 00:40:07 BST 2004 Tom Gilbert <tom@linuxbrit.co.uk>
346 * fixed insult plugin
347 * fixed excuse plugin
349 Thu Oct 07 23:28:05 BST 2004 Tom Gilbert <tom@linuxbrit.co.uk>
351 * searching for urls in the url plugin
352 * roshambo (rock/paper/scissors) plugin from Hans Fugal <hans@fugal.net>
354 Sat Apr 17 20:56:50 BST 2004 Tom Gilbert <tom@linuxbrit.co.uk>
356 * Oh, found new tv plugin in my inbox from ages ago, but it's still not
357 working so I guess it changed again since then
358 * New eightball plugin from Daniel Free
360 Sat Apr 17 20:44:43 BST 2004 Tom Gilbert <tom@linuxbrit.co.uk>
362 * Fixed the babelfish parser so translate works again.
364 * Note some plugins are broken (excuse,insult) because the server they use
365 went away. I don't know of a replacement right now.
366 * tv plugin seems broken, perhaps the html changed.
368 Thu Jan 15 21:37:38 GMT 2004 Tom Gilbert <tom@linuxbrit.co.uk>
373 * new plugin from Alan Third <alan@idiocy.org>, allows you to search and list
377 * various plugin updates
378 * fix (again) for C to F temp conversion in weather plugin
379 * channel topic patch from Peter Suschlik, gives plugin better access to topic
380 changes and related information
383 * changes to layout of slashdot plugin output
384 * freshmeat plugin, show latest updates or search
385 * fix to C to F temp conversion in weather plugin
386 * status command returns some bot status
388 * using BDB::Btree everywhere now, instead of BDB::Hash, because the Btree api
389 allows me to set my own key comparison function. This is needed to keep
390 supporting case insensitivity (vital for IRC), which was sadly broken in
391 0.9.5 :( All existing dbs will be upgraded automatically.
392 * roulette plugin - play russian roulette :) also keeps game stats.
393 * new config option, NO_KEYWORD_ADDRESS. If set to "true", the bot will always
394 respond to keywords it knows even when not addressed and the message doesn't
395 start with '. Message must end with "?" however.
396 * hopefully fixed welcome message parsing from certain server types
399 * plugin object registry
400 This provides persistant storage for plugins via a hash interface. The
401 default mode is an object store, so you can store ruby objects and reference
402 them with hash keys. This is because the default store/restore methods of
403 the plugins' RegistryAccessor are calls to Marshal.dump and Marshal.restore,
407 @registry[:blah] = blah
408 then, even after the bot is shut down and disconnected, on the next run you
409 can access the blah object as it was, with:
410 blah = @registry[:blah]
411 The registry can of course be used to store simple strings, fixnums, etc as
412 well, and should be useful to store or cache plugin data or dynamic plugin
415 If you don't need to store objects, and strictly want a persistant hash of
416 strings, you can override the store/restore methods to suit your needs, for
417 example (in your plugin):
428 Your plugins section of the registry is private, it has its own namespace
429 (derived from the plugin's class name, so change it and lose your data).
430 Calls to registry.each etc, will only iterate over your namespace.
432 The nickserv and karma plugins use the new registry and should serve as a
433 useful example. Basic usage of the registry is simple, just treat it as a
434 hash, with values that never die (unless you delete() them).
435 * Change to the nickserv plugin. The old method of putting the nickserv
436 password in rbot.conf was useless for multiple nicks or easy updates. The
437 plugin now uses the plugin registry to store passwords for any nicks it
438 owns. The plugin can be told to register the current nick (supply a password
439 or it'll generate one), identify for the current nick (if the password is
440 known), and can be told the passwords for other nicks. If NickServ asks the
441 bot to identify, it will automatically do so if it knows the appropriate
443 * karma plugin now uses the plugin registry, it should automatically import
444 your existing, stored karma data into the registry.
445 * The babelfish plugin now caches results in the bot registry to speed up
447 * New message types and plugin methods to grab them,
448 quit(QuitMessage): Called when a user (or the bot) quits IRC
449 nick(NickMessage): Called when a user (or the bot) changes Nick
450 topic(TopicMessage): Called when a user (or the bot) changes a channel topic
451 * A plugin's listen() method will now receive any kind of Message, e.g.
452 PrivMessage, NoticeMessage, NickMessage, JoinMessage, etc
454 seen: the usual "seen" stuff:
456 giblet was last seen xxx ago doing xxx
457 cal: calls the unix cal program to display a calendar
458 math: evaluates mathematical expressions:
460 rbot: math 4 to the power of 8
461 rbot: math ((232+432) - 4) / 2
462 (ported from infobot. Thanks to Kevin Lenzo, who wrote the
463 original infobot math module)
464 slashdot: displays latest headlines or searches for articles
465 url: stores urls mentioned in channels for regurgitation later
466 weather: grabs and parses METAR weather data, will remember the last weather
467 code you asked for so you don't have to :)
468 * New utility function, Util.http_get(url) for getting remote data via http,
469 just dumps response.body into a string and returns it, or nil if anything at
470 all goes wrong. Useful for simple plugins.
471 * random quit messages if none specified, messages set in language description
473 * keywords are now stored in bdb databases - your old keywords.rbot will be
474 imported. Static keywords (fact packs) are also stored in bdb databases, and
475 rbot will automatically convert any text .fact file dropped in the confdir's
476 keywords subdirectory, at startup, into a bdb file. If both a db and a text
477 file exist of the same name (except the extension), the text file will be
478 imported and merged into the database.
479 static keywords will be looked up in each factpack db in turn, in
480 alphabetical filename order - so you can prioritise using the filename if
482 * fixed a bug with autsplitting long sent lines, the last line was often being
486 * Massive cleanup of rfc2812.rb, contributed by Lars Christensen
487 <dsl8950@vip.cybercity.dk>, gets rid of a lot of regexps
488 * Fixed bug reading static keyword files - "foo <=is=> bar" may not have
489 worked for a couple of releases, only "foo<=is=>bar" was working - this was
490 not intended and should be fixed now
491 * Experimental send queue, to prevent the bot from flooding out, the delay
492 between sending messages to the server defaults to 2s, but is configurable
493 in conf.rbot, set SENDQ_DELAY (0 to disable queueing). You can also set/get
494 the value from the bot, "rbot: options get sendq_delay", and
495 "rbot: options set sendq_delay 1.5", if you have sufficient auth for "config"
496 This is a bursting sendq, most ircd's allow bursts of up to 5
497 lines, with non-burst limits of 512 bytes/2 seconds. To set the burst limit,
498 configure SENDQ_BURST in conf.rbot, or do the same kind of stuff with
499 "rbot: options set sendq_burst 2", etc.
500 The defaults are 2s/4 burst, which seem to work okay for me.
501 * support for multiple, customisable, addressing prefixes. Set ADDRESS_PREFIX
502 in conf.rbot to a space separate list of addressing prefixes, e.g
503 ADDRESS_PREFIX = | ! =>
504 Would mean that all of the following in channel messages would cause the bot
510 * bb plugin removed, bb is nearly over and it doesn't work 100% anyway
511 * Two plugins from brailsmt (from #ruby-lang on openprojects), a stats plugin
512 which monitors usage of 1-word sentences, and lart, which allows you to ask
513 rbot to lart people - with an optional reason - larts are user-definable and
514 can be added on the fly.
515 * made google.rb work for people with 1.6 ruby's net/http
520 * new plugin for handling nickserv-protected nicks, use NICKSERV_PASSWORD in
522 * fixes to a few other buglets
523 * new plugin to grab bigbrother headlines, still buggy and only useful for UK
524 folks who love bb :-)
525 * fixes to various plugins
526 * Patch from akira yamada <akira@ruby-lang.org>
527 DNS plugin: Use resolv-replace if found, do lookup in new thread
528 Fix bug joining channels with keys
532 * better "connect failure" error message
533 * better option parsing, and --debug option
534 * access to bot's online help via commandline, eg:
536 ./rbot.rb --help core
537 ./rbot.rb --help "core save"
538 * Fix broken help from last point release
539 * Plugin API modification and cleanup. You no longer need to set @listen to
540 true in order to get all NOTICE and PRIVMSGs, you just need to define the
541 method. The method is now called listen(), renamed from listener(). This
542 should be the last time the plugin api is changed incompatibly.
543 * New plugin method kick(). Use it to see kicks (duh :))
544 * New plugin methods join(), part(). Obvious uses.
545 * Example plugin autorejoin.rb, uses kick event to rejoin channel and insult
547 * fix bug in remind plugins "remind me no more" recognition.
551 * Fix welcome message recognition for certain IRCd's.
555 * Allow keyword definitions which end in '?', like this:
557 * rdoc documentation!
558 * fixed broken address regexp, "rbot: .foo" was being treated as an addressed
559 form of "foo" (lost the .)
560 * fix stupid bug in last release (looking for wrong default conf dir)
564 * Tarball layout change. modules all in rbot/ now, and the rbot/ default
565 configuration moved to rbotconf/. This lets the thing run from an unpacked
566 tarball while also being ready to run with the modules installed somewhere
568 * change hashbang to /usr/bin/env ruby, in order to use PATH looking for ruby,
570 * allow "botnick : foo" style addressing, and even "botnick... foo"
571 * slap plugin (contributed by oct)
572 * renamed bot.send to bot.sendmsg, I didn't really want to override send() ;D
576 * Made sane for packagers. Looks in the right places for plugins and language
577 files now, so extra effort shouldn't be needed there.
581 * Fixed "nick taken on join" bug
582 * Dice plugin patch from David Dorward
583 * fix searchquote regexp
584 * conf.rbot: PASSWORD -> SERVER_PASSWORD, to prevent confusion with PASSWD,
585 which is for master auth.
589 * Fixed addquote (was incrementing quote ID twice)
590 * now strips colour/bold escapes from incoming messages (rbot was ignoring
591 messages addressed using a bolded colon, for example).
593 * more language breadth
594 * Addressing works better now
595 * Can autojoin channels with keys, conf.rbot line is:
596 autojoin_channels #chan1, #chan2, #chan3 key, #chan4 key, #chan5
