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!")

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.

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

Examples:

• 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.

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:

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

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.

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 http://www.oftc.net/oftc/NickServ/CertFP.

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.

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:

~/.weechat/
    |- 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

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

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
