Note
(1) Name comes from the Debian GNU/Linux distribution, versions and package names may be different in different distributions and versions.
(2) WeeChat can compile with libncurses5-dev, but it is NOT recommended (you will have display bugs with wide chars).

2.2.2. Compile with cmake

$ mkdir build
$ cd build
$ cmake ..
$ make
% make install    (as root)
$ mkdir build
$ cd build
$ cmake .. -DPREFIX=/path/to/directory
$ make
$ make install

2.2.3. Compile with autotools

$ ./configure
$ make
% make install    (as root)
$ ./configure --prefix=/path/to/directory
$ make
$ make install

2.3. Git sources

Warning: GIT sources are for advanced users: it may not compile or not be stable. You’re warned!

To get GIT sources, issue this command:

$ git clone git://git.sv.gnu.org/weechat.git

If you’re using autotools (and not cmake), execute this script:

$ ./autogen.sh

Then follow instructions for source package (see source package).

2.4. Report crashes

If you experienced crashes, or if you want to report any future WeeChat crash, you have to:

2.4.1. Debug info

If you’re compiling with cmake:

$ cmake .. -DCMAKE_BUILD_TYPE=Debug

If you’re compiling with autotools, debug is default (--with-debug=1).

If you installed a binary package, then install package weechat-dbg.

2.4.2. Core files

To enable core files, you have to use ulimit command.

For example under Linux with bash shell, add this line to your ~/.bashrc:

ulimit -c unlimited

Or max size:

ulimit -c 200000

2.4.3. Get backtrace with gdb

When WeeChat crashes, your system will create a file core or core.12345 (12345 is process id). This file is created in directory where you have run WeeChat (this is not directory where WeeChat is installed!).

For example if weechat-curses is installed in /usr/bin/ and core file is in /home/xxx/, then run gdb with this command:

gdb /usr/bin/weechat-curses /home/xxx/core
Note
If you installed binary package weechat-dbg (for example under Debian), then you can use this path for WeeChat binary: /usr/lib/debug/usr/bin/weechat-curses

Then under gdb, use command bt full to display backtrace. You will see something like that:

(gdb) bt full
#0  0x00007f9dfb04a465 in raise () from /lib/libc.so.6
#1  0x00007f9dfb04b8e6 in abort () from /lib/libc.so.6

        tv_time = {tv_sec = 1272693881, tv_usec = 212665}
        ptr_hook = 0x2811f40
        next_hook = 0x0
#6  0x000000000041b5b0 in gui_main_loop () at /some_path/src/gui/curses/gui-curses-main.c:319
        hook_fd_keyboard = 0x173b600
        tv_timeout = {tv_sec = 0, tv_usec = 0}
        read_fds = {fds_bits = {0 <repeats 16 times>}}
        write_fds = {fds_bits = {0 <repeats 16 times>}}
        except_fds = {fds_bits = {0 <repeats 16 times>}}
        max_fd = <value optimized out>

You must report this trace to developers, and tell them what action caused this crash.

Thank you for your help!

4. Plugins

To learn more about plugin or script development (through API), please read WeeChat Plugin API Reference or WeeChat Scripting Guide.

4.1. Plugins in WeeChat

A plugin is dynamic library, written in C and compiled, which is loaded by WeeChat. Under GNU/Linux, the file has ".so" extension, ".dll" under Windows.

Plugins found are automatically loaded when WeeChat is starting, and it is possible to load or unload plugins while WeeChat is running.

It’s important to make difference between a plugin and a script: a plugin is a binary file compiled and loaded with command /plugin, whereas a script is a text file loaded with a plugin like perl with command /perl.

You can use command /plugin to load/unload a plugin, or list all loaded plugins. When a plugin is unloaded, all buffers created by this plugin are automatically closed.

Examples to load, unload or list plugins:

/plugin load irc
/plugin unload irc
/plugin list

Default plugins are:

Plugin Description

alias

Define alias for commands

aspell

Spell checking for command line

charset

Charset decoding/encoding for buffers

demo

Demo plugin (not compiled by default)

fifo

FIFO pipe used to remotely send commands to WeeChat

irc

IRC chat protocol

logger

Log buffers to files

perl

Perl scripting API

python

Python scripting API

ruby

Ruby scripting API

lua

Lua scripting API

tcl

Tcl scripting API

xfer

File transfer and direct chat

4.2. Alias plugin

Alias plugin lets you create alias for commands (from WeeChat or other plugins).

4.2.1. Commands

/alias [[-completion completion] alias_name [command [arguments]]]
  create an alias for a command

  completion: completion for alias (optional, by default completion is done with target command)
  alias_name: name of alias (can start or end with "*" for alias listing)
     command: command name (many commands can be separated by semicolons)
   arguments: arguments for command

  Without argument, this command lists all defined alias.

  Note: in command, special variables are replaced:
          $n: argument 'n' (between 1 and 9)
         $-m: arguments from 1 to 'm'
         $n-: arguments from 'n' to last
        $n-m: arguments from 'n' to 'm'
          $*: all arguments
          $~: last argument
       $nick: current nick
    $channel: current channel
     $server: current server

  To remove an alias, use command /unalias.

  Examples:
    alias /split to split window horizontally:
      /alias split /window splith
    alias /hello to say "hello" on all channels but not on #weechat:
      /alias hello /allchan -exclude=#weechat msg * hello
    alias /forcejoin to send IRC command "forcejoin" with completion of /sajoin:
      /alias -completion %%sajoin forcejoin /quote forcejoin

4.3. Aspell plugin

Aspell plugin lets you check spelling in command line. It is possible to use many languages by buffer.

4.3.1. Options (aspell.conf)

4.3.2. Commands

/aspell dictlist | enable lang | disable | addword [lang] word
  aspell plugin configuration

  dictlist: show installed dictionaries
    enable: enable aspell on current buffer
   disable: disable aspell on current buffer
   addword: add a word in your personal aspell dictionary

  Input line beginning with a '/' is not checked, except for some commands.

4.4. Charset plugin

Charset plugin lets you decode or encode data using charsets.

There is default charset for decode/encode, and specific charsets for buffers (or group of buffers).

This plugin is optional, but recommended: if it’s not loaded, WeeChat can only read/write UTF-8 data.

Charset plugin should be autoloaded by WeeChat. To be sure plugin is loaded, try:

/charset

If command is not found, then load plugin with command:

/plugin load charset

If plugin is not found, then you should compile again WeeChat with plugins and Charset support.

When Charset plugin starts, it displays terminal and internal charsets. Terminal charset depends on your locale, and internal is UTF-8.

For example:

charset: terminal: ISO-8859-15, internal: UTF-8

4.4.1. Options (charset.conf)

4.4.2. Commands

/charset [[decode | encode] charset] | [reset]
  change charset for current buffer

   decode: change decoding charset
   encode: change encoding charset
  charset: new charset for current buffer
    reset: reset charsets for current buffer

4.4.3. Set charset

To set global decode and encode charsets, use command /set.

For example:

/set charset.default.decode ISO-8859-15
/set charset.default.encode ISO-8859-15

If global decode charset is not set (for example during first load of Charset plugin), it will be automatically set to terminal charset (if it’s different from UTF-8), or by default to ISO-8859-1.

Default encode value is empty, so it sends by default with internal charset (UTF-8).

To set IRC server charset, use command /charset on server buffer. If you give only charset, then it will set decoding and encoding values.

For example:

/charset ISO-8859-15

It’s equivalent to:

/charset decode ISO-8859-15
/charset encode ISO-8859-15

To set IRC channel (or private) charset, use same commands as server, but on channel (or private) buffer.

To see all charsets used, use following command:

/set charset.*

4.4.4. Troubleshooting

For any problem with charsets, please look at WeeChat FAQ.

4.5. Fifo plugin

You can remote control WeeChat, by sending commands or text to a FIFO pipe (if option "plugins.var.fifo.fifo" is enabled, it is by default).

The FIFO pipe is located in ~/.weechat/ and is called weechat_fifo_xxxx (where xxxx is the process ID (PID) of running WeeChat).

Syntax for the FIFO pipe commands/text is one of following:

  plugin.buffer *text or command here
  *text or command here

Some examples:

$ echo 'irc.server.freenode */nick newnick' >~/.weechat/weechat_fifo_12345
$ echo 'irc.freenode.#weechat *hello!' >~/.weechat/weechat_fifo_12345
$ echo '*hello!' >~/.weechat/weechat_fifo_12345
$ echo -e '*/perl unload\n*/perl autoload' >~/.weechat/weechat_fifo_12345

You can write a script to send command to all running WeeChat at same time, for example:

#!/bin/sh
if [ $# -eq 1 ]; then
    for fifo in ~/.weechat/weechat_fifo_*
    do
        echo -e "$1" >$fifo
    done
fi

If the script is called "auto_weechat_command", you can run it with:

$ ./auto_weechat_command 'irc.freenode.#weechat *hello'

4.6. IRC plugin

The IRC plugin is designed to chat through IRC protocol with other people.

It is multi-servers, and offers all supported IRC commands including DCC chat and file transfer (via xfer plugin, see Xfer plugin).

4.6.1. Command line options

It is possible to give URL for one or many IRC servers, as follow:

irc[6][s]://[pseudo[:mot_passe]@]irc.example.org[:port][/channel][,channel[...]

Example to join #weechat and #toto on server irc.freenode.net server, default port (6667), with nick nono:

$ weechat-curses irc://nono@irc.freenode.net/#weechat,#toto

4.6.4. SSL certificates

When connecting to IRC server with SSL, WeeChat checks by default that the connection is fully trusted.

Some options are used to control SSL connection:

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 (for example CertFP on oftc, see below)

irc.server.xxx.ssl_dhkey_size

size of the key used during the Diffie-Hellman Key Exchange (by default: 2048)

irc.server.xxx.ssl_verify

check that the SSL connection is fully trusted (on by default)

Note
Option "ssl_verify" is on by default, so verification is strict and may fail, even if it was ok with versions prior to 0.3.1.
First example: connect to oftc and check certificate
$ mkdir ~/.weechat/ssl
$ wget -O ~/.weechat/ssl/CAs.pem http://www.spi-inc.org/secretary/spi-cacert.crt

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

/connect oftc
Second example: connect to oftc using CertFP
$ openssl req -nodes -newkey rsa:2048 -keyout nick.key -x509 -days 365 -out nick.cer
$ cat nick.cer nick.key > ~/.weechat/ssl/nick.pem
/set irc.server.oftc.ssl_cert "%h/ssl/nick.pem"
/connect oftc
/msg nickserv cert add

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

4.6.5. Smart filter for join/part/quit messages

A smart filter is available to filter join/part/quit messages when nick did not say something during past X minutes on channel.

Smart filter is enabled by default, but you must add a filter to hide lines on buffers, for example:

/filter add irc_smart * irc_smart_filter *

It is possible to create filter for one channel only or channels beginning with same name (see /help filter):

/filter add irc_smart_weechat irc.freenode.#weechat irc_smart_filter *
/filter add irc_smart_weechats irc.freenode.#weechat* irc_smart_filter *

You can hide only join or part/quit with following options:

/set irc.look.smart_filter_join on
/set irc.look.smart_filter_quit on

You can setup delay (in minutes):

/set irc.look.smart_filter_delay 5

If a nick did not speak during last 5 minutes, its join and/or part/quit will be hidden on channel.

4.6.6. CTCP replies

It is 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

Following codes can be used in strings and are automatically expanded by WeeChat when replying to CTCP:

/set irc.msgbuffer.whois private
/unset irc.msgbuffer.whois
/set irc.msgbuffer.freenode.invite current

4.7. Logger plugin

The Logger plugin lets you save content of buffers to files, with options about what and how it is saved.

4.7.1. Options (logger.conf)

4.7.2. Commands

/logger [list | set level | disable]
  logger plugin configuration

     list: show logging status for opened buffers
      set: set logging level on current buffer
    level: level for messages to be logged (0 = logging disabled, 1 = a few messages (most important) .. 9 = all messages)
  disable: disable logging on current buffer (set level to 0)

  Options "logger.level.*" and "logger.mask.*" can be used to set level or mask for a buffer, or buffers beginning with name.

  Examples:
    set level to 5 for current buffer:
      /logger set 5
    disable logging for current buffer:
      /logger disable
    set level to 3 for all IRC buffers:
      /set logger.level.irc 3
    disable logging for main WeeChat buffer:
      /set logger.level.core.weechat 0
    use a directory per IRC server and a file per channel inside:
      /set logger.mask.irc "$server/$channel.weechatlog"

  Log levels used by IRC plugin:
    1: user message, notice, private
    2: nick change
    3: server message
    4: join/part/quit
    9: all other messages

4.7.3. Log levels

Logging is made with a level for each buffer. Default level is 9 (log all messages displayed on buffer). You can change level for one buffer, or a group of buffers.

Possible levels are 0 to 9. Zero means "do not log anything" and 9 means "log all messages".

Plugins are using different levels for messages displayed. IRC plugin uses following levels:

So if you set level 3 for an IRC channel, WeeChat will log all messages, but not join/part/quit.

Some examples:

/set logger.level.irc.freenode.#weechat 3
/set logger.level.irc.server.freenode 3
/set logger.level.irc.freenode 3
/set logger.level.irc 2

4.7.4. Filenames masks

It is possible to define a filename mask for each buffer, and use local buffer variables to build filename. To see local variables for current buffer:

/buffer localvar

For example if you want one directory by IRC server and one file by channel inside:

/set logger.mask.irc "irc/$server/$channel.weechatlog"

You’ll have following files:

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