New plugin Javascript

A new plugin called "javascript" has been added to WeeChat. You can now load and execute Javascript scripts in WeeChat!

This plugin uses Google's v8 engine.

WeeChat now supports Python, Perl, Ruby, Lua, Tcl, Guile and Javascript!

The support of a new SASL mechanism called "ecdsa-nist256p-challenge" has been added three weeks ago.
This new mechanism uses a challenge with public/private key, so no password is required to connect.

Instructions to configure and use this mechanism are in user's guide: https://weechat.org/doc/devel/user/en/#irc_sasl_authentication.

Important notes:

  • GnuTLS ≥ 3.0.21 is required.
  • This mechanism can only be used on servers supporting it (for example servers using atheme, like freenode).

Exec plugin

A new plugin called "exec" has been added, with command /exec.

The command /exec can execute external commands and display output in WeeChat.

It is similar to /shell (script shell.py), with major improvements:

  • run many commands at once,
  • send signals to commands,
  • send data on stdin of a command,
  • line numbers in output,
  • ANSI color support,
  • command timeout.

Other features coming soon: pipe output to WeeChat command or hsignal (to use in a trigger).

Trigger plugin

A new plugin called "trigger" has been added.

This plugin can hook many things:

  • signal
  • hsignal
  • modifier
  • print
  • command
  • command_run
  • timer
  • config
  • focus

When the callback is called, trigger can:

  • check some conditions (to execute the trigger or not), which are evaluated (see /help eval)
  • replace some text using regular expression(s)
  • execute command(s)
  • have a custom return code.

Example of things you can do with trigger:

  • notification, for example beep on highlight/private message (it can replace script beep.pl or other scripts)
  • hide passwords in commands/messages (it will replace rmodifier plugin)
  • change content of messages displayed
  • change things displayed (nicklist, ...) when terminal becomes small
  • regularly save config files (with a timer)
  • ...

Help is available with /help trigger.

Some examples of triggers can be found on GitHub WeeChat wiki.

CRC32 and IPv6 in xfer plugin

CRC32 and IPv6 are now supported in xfer plugin!

For CRC32, a new option has been added:

  • xfer.file.auto_check_crc32 (boolean, off by default): when enabled, if the filename has a CRC32 (8 hexadecimal chars with delimiters around), the CRC32 of file content is checked and the result is displayed in xfer buffer (with error in core buffer if the CRC32 is wrong).

For IPv6, everything is automatic; it works for DCC file and chat.

Note for C plugin developers: the function "weechat_network_connect_to" has been modified to be used with IPv6. See the plugin API reference for more info.

A big thanks to Andrew Potter for the patches!

The IRC smart filter... even smarter!

A new option has been added for the IRC smart filter: irc.look.smart_filter_join_unmask, with default value 30 (in minutes).

IRC plugin will automatically unmask a filtered join of a nick, if he spoke within N minutes after the join (N being the value of new option irc.look.smart_filter_join_unmask). Moreover, nick changes are tracked, and will be unmasked with the join.

Events triggering the unmask of join are: a message (can be CTCP), a notice or an update of topic.

WebSocket in relay plugin

Websocket has been added in relay plugin, for IRC and WeeChat protocols.

It is an experimental and partial implementation of RFC 6455: fragmentation and control frames are not yet supported.

The relay plugin automatically detects WebSocket handshake and if everything is OK (origin allowed and required headers received), an answer to handshake is sent and then socket is ready to send/receive WebSocket frames.

Text and binary data are supported, so IRC (text/text) and WeeChat (text/binary) protocols are supported.

Backlog for irc protocol in relay

Backlog has been added for irc protocol in relay plugin.

The relay plugin now supports server capability "server-time", to include the messages time as tag (not in the message itself).

5 new options have been added:

  • relay.irc.backlog_max_minutes
  • relay.irc.backlog_max_number
  • relay.irc.backlog_since_last_disconnect
  • relay.irc.backlog_tags
  • relay.irc.backlog_time_format

Enjoy, and merry Christmas!

Tags in IRC messages

Tags in IRC messages are now supported (in development version, planned for version 0.4.0), following this specification: http://ircv3.atheme.org/specification/message-tags-3.2.

The tag "time" is now read and is used to set the time for the message displayed.

The "znc" IRC bouncer is using this tag with the capability "znc.in/server-time-iso" (name should change in the next release). For example if you are using a server called "znc" in WeeChat, you can do:

/set irc.server.znc.capabilities "znc.in/server-time-iso"

Note: with znc 1.0, the server capability was "znc.in/server-time". With znc git > 1.0, the capability is "znc.in/server-time-iso".

Some info about capability "server-time": https://github.com/atheme/ircv3-specifications/blob/master/extensions/server-time-3.2.

Scripts manager

A new scripts manager has been added, the plugin is called "script" and provides the /script command.

This plugin will replace two scripts: weeget.py (the current scripts manager) and script.pl (providing a /script command to load/unload/reload scripts for any language).

The new /script command is similar to command /weeget with some minor differences (see /help script for more info).

The plugin provides a buffer with list of scripts in repository, which makes installation or removal of scripts very fast: just press alt+i on this buffer, and the script is installed! Not satisfied with the script? Key alt+r and the script is gone!

The buffer allows you to search string in scripts (description, tags, ...) and to sort scripts with many keys. Columns displayed can be fully customized (order, columns displayed), as well as colors.

For list of options, just do: /set script.*

SSL in Relay plugin

SSL support has been added in Relay plugin, for irc and weechat protocols.

A new option has been added to set the certificate and private key to use:

  • relay.network.ssl_cert_key: path to file with certificate and private key (default: ~/.weechat/ssl/relay.pem)

The file can be created with following commands:

$ mkdir -p ~/.weechat/ssl
$ cd ~/.weechat/ssl
$ openssl req -nodes -newkey rsa:2048 -keyout relay.pem -x509 -days 365 -out relay.pem

In WeeChat :

/relay sslcertkey

And add relays with SSL, for example:

/relay add ssl.irc.freenode 8001
/relay add ssl.weechat 9001

And now WeeChat will serve clients on these ports using SSL, enjoy!

Support of Python 3

WeeChat can now compile with Python 3.x (successfully tested with Python 3.1 and 3.2).
This is still experimental and recommended Python for WeeChat remains version 2.7.

Some scripts (including weeget.py) have been updated for Python 3.x, they have tag "py3k-ok" on the scripts page: https://weechat.org/scripts/stable/tag/py3k-ok/

Python versions supported by WeeChat:

  • 2.5: many scripts require at least 2.6 - NOT recommended
  • 2.6: all scripts should work fine
  • 2.7: recommended version (all scripts are guaranteed to work with this version)
  • 3.x: experimental, should be used only for tests

Note that "python" plugin in WeeChat can support only one version, so it can be a 2.x or 3.x, not both at same time.

Thursday, October 27 2011

New plugin Guile

A new plugin called "guile" has been added to WeeChat. You can now load and execute Scheme scripts in WeeChat!

WeeChat now supports Python, Perl, Ruby, Lua, Tcl and Guile!

To load/unload scheme scripts, command is /guile with same syntax as other script languages:

/guile load /path/to/example.scm
/guile reload example
/guile unload example

An example of script:

;; example.scm
(weechat:register "example" "FlashCode" "0.1" "GPL3" "Scheme script" "" "")
(weechat:print "" "Hey, I'm a scheme script for WeeChat!")

Options for aspell spellers

An "option" section has been added to aspell.conf file, to set options for aspell speller.

A commonly used option is "ignore-case" to ignore case in speller. To enable it, just do:

/set aspell.option.ignore-case "true"

For a list of aspell options, do in your shell:

aspell config

Redirection of IRC commands

It is now possible to redirect IRC commands to a callback, in plugins/scripts.

First you have to add a hsignal with callback, to receive command output. Then, add redirection by sending a hsignal, and send your command to IRC server. It will automatically use your redirection.

Each redirection uses a pattern, which defines start/stop/extra commands. Default patterns are: ison, list, mode_channel, mode_channel_ban, mode_channel_ban_exception, mode_channel_invite, mode_user, names, ping, time, topic, userhost, who, whois, whowas.

You can create your own pattern with signal "irc_redirect_pattern".

Examples of redirection and pattern creation are available in WeeChat devel doc.

New plugin rmodifier

A new plugin called "rmodifier" (for "Regex modifier") has been added.

It's designed to change some strings using regex, for example to hide passwords in commands (input displayed on screen) or in history. By default, password in following commands are hidden by this plugin:

  • /msg nickserv identify ****** (input and history)
  • /msg nickserv ghost ****** (input and history)
  • /oper nick ****** (input and history)
  • /set file.section.password ****** (history only)

Of course you can add your own regex, just look at /help rmodifier.

Custom completion for aliases

It is now possible to have custom completion for aliases, for example to complete with another command completion, or with your own completion.


  • create alias /forcejoin with completion of /sajoin: /alias -completion %%sajoin forcejoin /quote forcejoin
  • create alias /mybuf with custom completion: /alias -completion #weechat|#weechat-fr mybuf /buffer

You can change completion if alias is already created:

/set alias.completion.forcejoin "%%sajoin"

You can use empty string to prevent any completion for command (default is to complete using target command):

/set alias.completion.forcejoin ""

And you can remove a completion:

/unset alias.completion.forcejoin

Completion is automatically removed when you remove an alias with /unalias.

SASL authentication with IRC server

It is now possible to use SASL authentication with IRC server, using two mechanisms: "plain" (default) or "dh-blowfish" (crypted password).

New options have been added to servers:

  • sasl_mechanism: mechanism to use ("plain" or "dh-blowfish")
  • sasl_timeout: timeout (in seconds) for authentication
  • sasl_username: username
  • sasl_password: password

You just have to setup username (your nick) and password (password of nick) and then connect to server, you'll be identified with SASL if all is ok.

If you want to set "dh-blowfish" by default for all servers:

/set irc.server_default.sasl_mechanism dh-blowfish

Monday, February 1 2010

Date in log filenames

It is now possible to use date formaters in log filenames (in mask options).

For example to have log by year and month in separate directories, you can do :

/set logger.file.mask "%Y/%m/$plugin.$name.weechatlog"

You'll have a tree like that:

    |- logs/
        |- 2009/
            |- 12/
                |  irc.server.freenode.weechatlog
                |  irc.freenode.#weechat.weechatlog
        |- 2010/
            |- 01/
                |  irc.server.freenode.weechatlog
                |  irc.freenode.#weechat.weechatlog

New IRC output queue with high priority

A new IRC output queue has been added in irc plugin, with high priority. There are now two queues for messages sent to IRC server:

  • queue for user messages or commands, with high priority
  • queue for other messages, with low priority.

Low priority queue is used to send automatic messages, like replies to CTCP messages. So if you are spamed with CTCP messages, WeeChat will first send your messages (queue with high priority), and then CTCP replies (queue with low priority).

Accordingly, anti-flood option has been split into two options:

  • irc.network.anti_flood_prio_high: delay between two user messages/commands
  • irc.network.anti_flood_prio_low: delay between two other messages

Friday, January 8 2010

New IRC commands allchan and allserv

New commands have been added to IRC plugin: /allchan and /allserv.
These commands can execute a command on all buffer of all channels or all servers, with optional exclusion of some channels/servers.

Old commands /amsg and /ame are now replaced by aliases. If you're upgrading from recent version (>= 0.3.0), you have to manually create alias, see page with release notes.

Friday, January 1 2010

Target buffer for IRC messages

New options have been added to choose target buffer for IRC messages.

More info and examples in documentation: https://weechat.org/doc/devel/user#irc_target_buffer

SSL certificates

New options have been added to check SSL certificates when connecting to IRC servers, thanks to kolter's patch:

  • weechat.network.gnutls_ca_file: path to file with certificate authorities (by default: "%h/ssl/CAs.pem")
  • irc.server.xxx.ssl_cert: ssl certificate file used to automatically identify your nick (CertFP on oftc for example, see below)
  • irc.server.xxx.ssl_dhkey_size: replaces old option weechat.network.gnutls_dh_prime_bitsmax_lines, new default value is 2048 (safer than old default value which was 512)
  • irc.server.xxx.ssl_verify: check that the ssl connection is fully trusted (on by default)

Please note that ssl_verify is on by default, so verification is now stricter, and may fail even if it was ok with previous versions of WeeChat.

First example: connect to oftc and check certificate:

  • import certificate:
    • mkdir ~/.weechat/ssl
    • wget -O ~/.weechat/ssl/CAs.pem http://www.spi-inc.org/ca/spi-cacert.crt
  • in weechat:
    • /connect oftc

Note: it is possible to concatenate many CAs in file CAs.pem.

Second example: connect to oftc using CertFP (certificate to auto identify your nick):

  • create certificate:
    • openssl req -nodes -newkey rsa:2048 -keyout nick.key -x509 -days 365 -out nick.cer
    • cat nick.cer nick.key > ~/.weechat/ssl/nick.pem
  • in weechat:
    • /set irc.server.oftc.ssl_cert "%h/ssl/nick.pem"
    • /connect oftc
    • /msg nickserv cert add

For more information, please look at https://www.oftc.net/NickServ/CertFP.

IRC CTCP replies

It is now possible to customize CTCP replies, or block some CTCP queries (do not reply).

For example, to customize reply to CTCP "VERSION", use following command:

/set irc.ctcp.version "I'm running WeeChat $version, it rocks!"

If you want to block CTCP "VERSION" (do not reply to a query), then set empty string:

/set irc.ctcp.version ""

Even unknown CTCP can be customized, for example you can reply to CTCP "BLABLA":

/set irc.ctcp.blabla "This is my answer to CTCP BLABLA"

It is possible to customize CTCP for one server only, using its internal name before CTCP name:

/set irc.ctcp.freenode.version "WeeChat $version (for freenode)"

If you want to restore standard CTCP reply, then remove option:

/unset irc.ctcp.version

Some codes are automatically expanded by WeeChat when replying to CTCP, please read documentation for more information (User's guide, chapter: Plugins / IRC plugin / CTCP replies).

Friday, March 6 2009

New hook "process"

New hook type "process" has been added to WeeChat. You can use it in C plugins, and all scripts languages (perl, python, ruby, lua and tcl).

It runs a command with fork, and send you result (return code, stdout and stderr) via a callback, when command has ended, or if WeeChat output buffer is full (then it will be partial result of command). There is optional timeout (in milliseconds), to kill process if it's still running after given time.

The script shell.py has been updated to use that new hook.

Wednesday, November 26 2008

New plugin DC

A new plugin has been added: DC. It is used to transfer files using DC file-sharing protocol.

It's available as a separate plugin, and must be compiled and installed with WeeChat development version.
Documentation and screenshots are available on this wiki page: http://wiki.flashtux.org/wiki/WeeChat/dc

New logger features

Logger plugin has been improved with many new features:

  • command /logger (to see log status for open buffers, and set/disable log level on a buffer)
  • custom level by buffer (or group of buffers)
  • custom log filename mask by buffer (or group of buffers).

Set one directory by IRC server and a file by channel inside:

Do that: /set logger.mask.irc irc/$server/$channel.weechatlog

You'll have a tree like that:

    |- logs/
        |- irc/
            |--- freenode/
            |       freenode.weechatlog
            |       #weechat.weechatlog
            |       #mychan.weechatlog
            |--- oftc/
            |       oftc.weechatlog
            |       #chan1.weechatlog
            |       #chan2.weechatlog

Log all messages on IRC buffers but not join/part/quit messages:

  • for all IRC buffers: /set logger.level.irc 3
  • for a server and its channels: /set logger.level.irc.freenode 3
  • for a specific channel: /set logger.level.irc.freenode.#weechat 3

Smart IRC join/part/quit message filter

A new smart filter for IRC join/part/quit message has been added. It is disabled by default (so you'll see all join/part/quit by default).

To enable it, use following commands:

/set irc.look.smart_filter on
/filter add irc_smart * irc_smart_filter *

You can setup delay: /set irc.look.smart_filter_delay 5

How does it work?

When a nick spoke on channel during past X minutes (where X is delay irc.look.smart_filter_delay), its join/part/quit will be displayed by default. Otherwise, if nick did not speak for a long time, all join/part/quit messages will be tagged with "irc_smart_filter". So you have to define a filter on this tag to hide join/part/quit from users that are not speaking on channel (see command above).

Saturday, October 18 2008

Aspell plugin is born again

New aspell plugin is available!

Plugin as now its own configuration file, called aspell.conf. Options can be set with /set command. List of options with default value:

  • aspell.look.color = lightred
  • aspell.check.commands = "ame,amsg,away,command,cycle,kick,kickban,me,msg,notice,part,query,quit,topic"
  • aspell.check.default_dict = ""
  • aspell.check.word_min_length = 2

You can enable aspell for all buffers with default dictionary (or list of dictionaries), with command: /set aspell.check.default_dict "en,fr"

To enable a specific language on a buffer, use: /aspell enable fr
If you speak both english and german (often english, less german), use: /aspell enable en,de

Monday, October 6 2008

New plugin Tcl

A new plugin Tcl has been added (thanks to Dmitry Kobylin). Some minor changes will be done about compiling (with autotools and cmake), but plugin should be ok today as-is.

Script samples using new API, including Tcl language, will be published soon.

Thursday, September 4 2008

Ignore command, reloaded!

The new /ignore command is now available. You can ignore nicks (or hostnames), using regex.

Note: this command will be improved in near future with more options.

Some exemples (you can find them with /help ignore):

  • ignore nick "toto" everywhere: /ignore add toto
  • ignore host "toto@domain.com" on freenode server: /ignore add toto@domain.com freenode
  • ignore host "toto*@*.domain.com" on freenode/#weechat: /ignore add toto*@*.domain.com freenode #weechat

Tuesday, May 6 2008

Xfer plugin

A new "xfer" plugin has been added. It replaces old IRC DCC code.
This plugin is called by IRC plugin to initiate direct chat and file transfer (still by /dcc command). In future, it may be used by other plugins. Moreover, new protocols can be easily added to xfer plugin, if other plugins need that.
