----------------------------------------

[[compile_with_autotools]]
Compile with autotools
^^^^^^^^^^^^^^^^^^^^^^

[WARNING]
Only cmake is officially supported to build WeeChat. You should use autotools
only if you are not able to use cmake. +
Build with autotools requires more dependencies and is slower than with cmake.

* Installation in system directories (requires 'root' privileges):

----------------------------------------
$ ./autogen.sh
$ ./configure
$ make
% make install    (as root)
----------------------------------------

* Installation in custom directory:

----------------------------------------
$ ./autogen.sh
$ ./configure --prefix=/path/to/directory
$ make
$ make install
----------------------------------------

Options can be used for 'configure' script, they can be displayed with this
command:

----------------------------------------
$ ./configure --help
----------------------------------------

[[git_sources]]
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
----------------------------------------

Then follow instructions for source package (see
<<source_package,source package>>).

[[report_crashes]]
Report crashes
~~~~~~~~~~~~~~

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

* compile it with debug info (or install binary package with debug info)
* enable 'core' files on your system
* install gdb

[[debug_info]]
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'.

[[core_files]]
Core files
^^^^^^^^^^

To enable 'core' files, you can use option
<<option_weechat.startup.sys_rlimit,weechat.startup.sys_rlimit>>:

----------------------------------------
/set weechat.startup.sys_rlimit "core:-1"
----------------------------------------

For WeeChat ≤ 0.3.8 or if you want to enable core files even before WeeChat
starts, you can 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
----------------------------------------

[[gdb_backtrace]]
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' is installed in '/usr/bin/' and 'core' file is
in '/home/xxx/', then run gdb with this command:

----------------------------------------
gdb /usr/bin/weechat /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'

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

----------------------------------------
(gdb) set logging file /tmp/crash.txt
(gdb) set logging on
Copying output to /tmp/crash.txt.
(gdb) bt full
#0  0x00007f9dfb04a465 in raise () from /lib/libc.so.6

        hook_process = 0x254eb90
        status = <value optimized out>
#5  0x000000000044cc7d in hook_timer_exec () at /some_path/src/core/wee-hook.c:1025
        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!

[[debug_running_weechat]]
Debug a running WeeChat
^^^^^^^^^^^^^^^^^^^^^^^

To debug a running WeeChat (for example if WeeChat seems blocked), you can use
gdb with process id (replace '12345' with PID of weechat process):

----------------------------------------
gdb /usr/bin/weechat 12345
----------------------------------------

Then like for a crash, use command `bt full`:

----------------------------------------
(gdb) bt full
----------------------------------------

[[usage]]
Usage
-----

[[running_weechat]]
Running WeeChat
~~~~~~~~~~~~~~~

Command line arguments:

include::cmdline_options.en.txt[]

To start WeeChat, issue this command:

----------------------------------------
$ weechat
----------------------------------------

When you run WeeChat for the first time, a default configuration file is
created, with default options. The default configuration file is:
'~/.weechat/weechat.conf'.

You can edit this file at your convenience to configure WeeChat or you can set
parameters with `/set` command in WeeChat (see
<<weechat_commands,WeeChat commands>>).

A 'buffer' is composed by a number, a name, lines displayed (and some other
data).

Examples of buffers:

* core buffer (created by WeeChat on startup, can not be closed)
* irc server (displays messages from server)
* irc channel
* irc private

A 'window' is a screen area which displays a buffer. It is possible to split
your screen into many windows.

Each window displays one buffer. A buffer can be hidden (not displayed by a
window) or displayed by one or more windows.

Example of horizontal split (`/window splith`):

[[bars]]
Bars
~~~~

A 'bar' is an area beside the chat that can contain any type of text.

The bar options can be set with options `weechat.bar.name.option` where `name`
is the name of the bar and `option` the option for this bar.

List of bar options:

[width="100%",cols="2m,2,10",options="header"]
|========================================
| Option | Values | Description

| type | `root`, `window` |
  A bar with type `root` is displayed exactly one time on screen, outside all
  windows. There is no root bar by default, but an example is the bar 'buffers'
  created by script 'buffers.pl' (sidebar with list of buffers). +
  A bar with type `window` is displayed in each window, for example if you
  split one time the screen (with `/window splith` or `/window splitv`), you
  will have one bar in each window. The four default bars ('title', 'status',
  'input', 'nicklist') have type `window`.

| position | `top`, `bottom`, `left`, `right` |
  Position of the bar: above/below chat, on the left/right.

| priority | integer ≥ 0 |
  Priority for display of bar: this is used for ordering the bars on screen when
  many bars have same type and position. +
  The bars are displayed from the edge of the screen to the center. A higher
  priority will display bar at the beginning, so closer to the edge. +
  Example: 'input' bar has priority 1000, so it is displayed before the 'status'
  bar, which has priority 500.

| size | integer ≥ 0 |
  The size of the bar: number of columns for position left/right, number
  of lines for position top/bottom. A size of `0` means automatic, so the size
  will be computed according to content displayed in bar.

| size_max | integer ≥ 0 |
  The maximum size for a bar, `0` = no limit (this option is used only if
  `size` = `0`).

| color_bg | color |
  The default background color for the bar.

| color_fg | color |
  The default text color for the bar.

| color_delim | color |
  The color for delimiters in bar.

| hidden | `on`, `off` |
  When option is `on`, the bar is hidden. +
  Note: instead of changing this option, the command `/bar` is preferred, for
  example: `/bar toggle nicklist` (see command <<command_weechat_bar,/bar>>).

| separator | `on`, `off` |
  When option is `on`, a separator (line) is displayed between this bar and
  other bars (or chat).

| items | string |
  A list of 'items' (see <<bar_items,items>> for more info).

| filling_left_right | `horizontal`, `vertical`, `columns_horizontal`, `columns_vertical` |
  Type of filling for a bar which has position `left` or `right` (see
  <<bar_filling,filling>> for more info).

| filling_top_bottom | `horizontal`, `vertical`, `columns_horizontal`, `columns_vertical` |
  Type of filling for a bar which has position `top` or `bottom` (see
  <<bar_filling,filling>> for more info).

| conditions | string |
  The conditions to display the bar (see <<bar_conditions,conditions>> for more
  info).
|========================================

[[bar_items]]
Items
^^^^^

The option 'items' is a string with a list of bar items, separated by a comma
(space between items on screen) or "+" (glued items).

The list of bar items is displayed with command `/bar listitems`.

Before or after item name, you can use chars (that are not alphanumeric, "-" or
"_"). They will be displayed before/after item with the delimiters color
defined in bar (option 'color_delim').

Example of bar with items "[time],buffer_number+:+buffer_plugin+.+buffer_name":

........................................
┌─────────────────────────────────────────────────────────────────────────────────────────┐
│[12:55] 3:irc/freenode.#weechat                                                          │
└─────────────────────────────────────────────────────────────────────────────────────────┘
........................................

A special syntax can be used to force the buffer used when displaying the bar
item: "@buffer:item" (where "buffer" is the full name of buffer and "item" is
the name of a bar item).

This is useful in root bars, to display item for a specific buffer which is
not displayed in the current window (or even not displayed at all).

Example: nicklist of bitlbee in a root bar (if the bar is called
'bitlist' and if bitlbee server is called 'bitlbee'):

----------------------------------------
/set weechat.bar.bitlist.items "@irc.bitlbee.&bitlbee:buffer_nicklist"
----------------------------------------

[[bar_filling]]
Filling
^^^^^^^

There are four types of filling:

* `horizontal`: the items are displayed horizontally, from left to right. If
  there are new lines in items, a space is used to separate lines.
* `vertical`: the items are displayed from top to bottom. If there are new
  lines in items, a new line is used to separate lines.
* `columns_horizontal`: items are displayed using columns, where text is
  aligned on the left. The first item is on top left, the second is on same
  line, on the right.
* `columns_vertical`: items are displayed using columns, where text is aligned
  on the left. The first item is on top left, the second is one line below.

Default bars 'title', 'status' and 'input' have 'horizontal' filling, and
default bar 'nicklist' has 'vertical' filling.

Some examples of filling for bar 'nicklist':

[[bar_conditions]]
Conditions
^^^^^^^^^^

The option 'conditions' is a string evaluated to know if the bar is displayed
or not in the window (it is used only for bars with type 'window').

The string can be:

* 'active': the window must be active
* 'inactive': the window must be inactive
* 'nicklist': the buffer displayed in window must have a nicklist
* an expression: it is evaluated as boolean (see command
  <<command_weechat_eval,/eval>>)

For the expression, following variables are available:

* `${active}`: true if window is active
* `${inactive}`: true if window is inactive
* `${nicklist}`: true if buffer displayed in window has a nicklist

Following pointers are available:

* `${window}`: the window where condition is evaluated
* `${buffer}`: the buffer of window where condition is evaluated

Example to display nicklist bar in all buffers with a nicklist, and only if
width of window is > 100 :

----------------------------------------
/set weechat.bar.nicklist.conditions "${nicklist} && ${window.win_width} > 100"
----------------------------------------

Same condition, but always display nicklist on buffer '&bitlbee' (even if window
is small):

----------------------------------------
/set weechat.bar.nicklist.conditions "${nicklist} && (${window.win_width} > 100 || ${buffer.full_name} == irc.bitlbee.&bitlbee)"
----------------------------------------

[[notify_levels]]
Notify levels
~~~~~~~~~~~~~

Four levels are possible in messages displayed in buffers, from lower to higher:

* 'low': message with low importance (for example irc join/part/quit)
* 'message': message from a user
* 'private': message in a private buffer
* 'highlight': message with highlight

Each buffer has a notify level, which is used to decide what messages will add
buffer in hotlist.

The default notify level can be set using option
<<option_weechat.look.buffer_notify_default,weechat.look.buffer_notify_default>>,
default is 'all'.

[width="50%",cols="3m,10",options="header"]
|========================================
| Notify level | Level of messages added to hotlist
| none         | (none)
| highlight    | 'highlight' + 'private'
| message      | 'highlight' + 'private' + 'message'
| all          | 'highlight' + 'private' + 'message' + 'low'
|========================================

Notify level can be defined for a set of buffers, for example all buffers of
irc server "freenode":

----------------------------------------
/set weechat.notify.irc.freenode message
----------------------------------------

Set notify level 'highlight' on channel "#weechat" only:

----------------------------------------
/set weechat.notify.irc.freenode.#weechat highlight
----------------------------------------

The notify level for a buffer can be set with command `/buffer`:

----------------------------------------
/buffer notify highlight
----------------------------------------

|========================================

[NOTE]
^(1)^ "⇑" and "⇓" are wheel up and down.

[[mouse]]
Mouse support
~~~~~~~~~~~~~

WeeChat supports mouse clicks and gestures. It is working with local terminal,
and remotely via ssh connection with or without screen/tmux.

[[mouse_enable]]
Enable mouse
^^^^^^^^^^^^

To enable mouse at startup:

----------------------------------------
/set weechat.look.mouse on
----------------------------------------

To enable mouse now, press @k(A-)@k(m) or do following command:

----------------------------------------
/mouse enable
----------------------------------------

It is possible to temporarily disable mouse, and bind that on a key. For example
key @k(A-)@k(x) to disable mouse for 10 seconds:

----------------------------------------
/key bind meta-x /mouse toggle 10
----------------------------------------

When mouse is enabled in WeeChat, you can use @k(-S-) modifier to select or
click in terminal, as if the mouse was disabled (on some terminals like iTerm,
you have to use @k(-A-) instead of @k(-S-)).

[NOTE]
For any problem with mouse, please look at 'WeeChat FAQ'.

[[mouse_bind_events]]
Bind mouse events to commands
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Many default mouse events are already defined by WeeChat (see
<<key_bindings_mouse_context,keys for "mouse" context>>).

You can change or add bindings with the command `/key` using context "mouse"
(for syntax, see <<command_weechat_key,command /key>>).

Event name consists of a modifier (optional), a button/wheel name and a gesture
(optional). Different elements are separated by "-".

List of modifiers:

[width="50%",cols="3m,4",options="header"]
|========================================
| Modifier | Description
| ctrl     | Key @k(-C-)
| alt      | Key @k(-A-)
| ctrl-alt | Keys @k(-C-) and @k(-A-)
|========================================

List of buttons/wheel:

[width="50%",cols="3m,4",options="header"]
|========================================
| Button/wheel        | Description
| button1             | Click on left button
| button2             | Click on right button
| button3             | Click on middle button (often click on wheel)
| button4 ... button9 | Click on extra buttons
| wheelup             | Wheel (up)
| wheeldown           | Wheel (down)
|========================================

List of gestures (only for buttons, not wheel):

[width="50%",cols="3m,4",options="header"]
|========================================
| Gesture            | Distance
| gesture-up         | 3 ... 19
| gesture-up-long    | ≥ 20
| gesture-down       | 3 ... 19
| gesture-down-long  | ≥ 20
| gesture-left       | 3 ... 39
| gesture-left-long  | ≥ 40
| gesture-right      | 3 ... 39
| gesture-right-long | ≥ 40
|========================================

List of incomplete events (only for buttons, useful for plugins/scripts):

[width="50%",cols="3m,4",options="header"]
|========================================
| Event      | Description
| event-down | Button was pressed but not released yet
| event-drag | Mouse was moved with button pressed down
|========================================

Example of events:

* `button1`
* `ctrl-button1`
* `button1-gesture-right`
* `button1-event-down`
* `button1-event-drag`
* `alt-button2-gesture-down-long`
* `wheelup`
* `ctrl-alt-wheeldown`
* ...

[TIP]
When binding a key in context "mouse", it's possible to match many events using
`*` at beginning or end of name, for example `button1-gesture-*` will match any
gesture made using left button.

[TIP]
You can find an event name with command `/input grab_mouse` then doing event
with mouse. This will insert event name on command line.

[[command_line]]
Command line
~~~~~~~~~~~~

WeeChat command line (at the bottom of window) lets you execute commands or
send text to buffer.

[[command_line_syntax]]
Syntax
^^^^^^

Commands begin with "/" char, followed by name of command. For example, to see
list of all options:

----------------------------------------
/set
----------------------------------------

Text sent to a buffer is any text that does not begin with "/" char.
For example, to send text 'hello' on current buffer:

----------------------------------------
hello
----------------------------------------

However, it is possible to start with "/" char, by adding another.
For example, to send text '/set' on current buffer:

----------------------------------------
//set
----------------------------------------

[[command_line_colors]]
Color codes
^^^^^^^^^^^

For some plugins like IRC, you can use color codes and attributes, as
follow (press @k(C-)@k(c) then following letter, with optional value):

@k(C-)@k(c) , @k(b)::
    bold text

@k(C-)@k(c) , @k(c) , @k(xx)::
    text color `xx` (see list of colors below)

@k(C-)@k(c) , @k(c) , @k(xx,yy)::
    text color `xx` and background `yy` (see list of colors below)

@k(C-)@k(c) , @k(o)::
    disable color and attributes

@k(C-)@k(c) , @k(r)::
    reverse video (revert text color with background)

@k(C-)@k(c) , @k(u)::
    underlined text

[NOTE]
The same code (without number for @k(C-)@k(c) , @k(c)) may be used to stop the
attribute.

Color codes for @k(C-)@k(c) , @k(c) are:

[width="50%",cols="^1m,3,3",options="header"]
|========================================
| Code | IRC           | WeeChat (curses)
| 00   | white         | white
| 01   | black         | black
| 02   | dark blue     | blue
| 03   | dark green    | green
| 04   | light red     | lightred
| 05   | dark red      | red
| 06   | magenta       | magenta
| 07   | orange        | brown
| 08   | yellow        | yellow
| 09   | light green   | lightgreen
| 10   | cyan          | cyan
| 11   | light cyan    | lightcyan
| 12   | light blue    | lightblue
| 13   | light magenta | lightmagenta
| 14   | gray          | gray
| 15   | light gray    | white
|========================================

Example: display of "hello everybody!" with "hello" in light blue bold and
"everybody" in light red underlined:

----------------------------------------
^Cc12^Cbhello ^Cb^Cc04^Cueverybody^Cu^Cc!
----------------------------------------

[NOTE]
In irc plugin, you can remap these colors using option
<<option_irc.color.mirc_remap,irc.color.mirc_remap>>.

[[colors]]
Colors
~~~~~~

WeeChat can use up to 256 color pairs to display text in bars and chat area
(your terminal must support 256 colors to use them in WeeChat).

According to value of 'TERM' environment variable, you may have following limits
for colors in WeeChat:

[width="50%",cols="8,>2,>2",options="header"]
|========================================
| $TERM                                 | Colors | Pairs ^(1)^
| "rxvt-unicode", "xterm",...           |     88 |         256
| "rxvt-256color", "xterm-256color",... |    256 |       32767
| "screen"                              |      8 |          64
| "screen-256color"                     |    256 |       32767
|========================================

[NOTE]
^(1)^ Even if your terminal supports more than 256 pairs, only 256 pairs can be
used in WeeChat, because of a ncurses limitation.

You can run `weechat --colors` or use command `/color` in WeeChat to
display limits for your environment.

Some recommended values for 'TERM' if you want 256 colors:

* under screen: 'screen-256color'
* outside screen: 'xterm-256color', 'rxvt-256color', 'putty-256color',...

[NOTE]
You may have to install package "ncurses-term" to use these values in 'TERM'
variable.

If you are using screen, you can add this line to your '~/.screenrc':

----------------------------------------
term screen-256color
----------------------------------------

If your 'TERM' variable has wrong value and that WeeChat is already running,
don't panic! You can change it without restarting, thanks to script 'shell.py':

----------------------------------------
/shell setenv TERM=screen-256color
/upgrade
----------------------------------------

[[colors_basic]]
Basic colors
^^^^^^^^^^^^

Basic colors in WeeChat are:

[width="50%",cols="^3m,8",options="header"]
|========================================
| Name         | Color
| default      | Default terminal color (transparent for background)
| black        | Black
| darkgray     | Dark gray
| red          | Dark red
| lightred     | Light red
| green        | Dark green
| lightgreen   | Light green
| brown        | Brown
| yellow       | Yellow
| blue         | Dark blue
| lightblue    | Light blue
| magenta      | Dark magenta
| lightmagenta | Light magenta
| cyan         | Dark cyan
| lightcyan    | Light cyan
| gray         | Gray
| white        | White
|========================================

[[colors_extended]]
Extended colors
^^^^^^^^^^^^^^^

WeeChat dynamically allocates color pairs when colors are used on screen (to
display buffers and bars).

In addition to basic colors, you can use a color number between 1 and the limit
of your terminal.

Use command `/color` to see current colors and limits. With @k(A-)@k(c) you can
temporarily switch to terminal colors to choose a color.

For example if you want to display time in orange in buffer, do:

----------------------------------------
/set weechat.color.chat_time 214
----------------------------------------

Or if you want a very dark green background for status bar:

----------------------------------------
/set weechat.bar.status.color_bg 22
----------------------------------------

[[colors_aliases]]
Aliases
^^^^^^^

You can add color aliases with command `/color alias` and then use this alias
in any color option.

For example:

----------------------------------------
/color alias 214 orange
/set weechat.color.chat_delimiters orange
----------------------------------------

[[colors_attributes]]
Attributes
^^^^^^^^^^

It is possible to use some attributes for colors. One or more attributes can be
added before color name or number:

* `*` : bold text
* `!` : reverse video
* `_` : underlined text
* `|` : keep attributes: do not reset bold/reverse/underlined when changing
  color

For example if you want self nick as white underlined, do:

----------------------------------------
/set weechat.color.chat_nick_self _white
----------------------------------------

Or if you want time in status bar as orange underlined with bold:

----------------------------------------
/set weechat.color.status_time *_214
----------------------------------------

To use an attribute with default terminal color (-1), you must use a number
greater than last terminal color, for example max color in WeeChat: 99999.

Example of bold with terminal foreground color:

----------------------------------------
/set weechat.color.status_time *99999
----------------------------------------

[[plugins]]
Plugins
-------

A plugin is a 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 'python' with command
`/python`.

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:

[width="50%",cols="^1,5",options="header"]

| Plugin    | Description
| alias     | Define alias for commands
| aspell    | Spell checking for command line

For example, to enable option "ignore-case":

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

[[aspell_suggestions]]
Suggestions
^^^^^^^^^^^

Suggestions are displayed in a bar item called "aspell_suggest". The number of
suggestions is set in option 'aspell.check.suggestions'.

To enable suggestions you must set option 'aspell.check.suggestions' to an
integer ≥ 0 and add the bar item "aspell_suggest" to a bar, like 'status'.

Example of suggestions with English dictionary (`en`):

[[charset_plugin]]
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
........................................

[[charset_commands]]
Commands
^^^^^^^^

include::autogen/user/charset_commands.txt[]

[[charset_set]]
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.*
----------------------------------------

[[charset_troubleshooting]]
Troubleshooting
^^^^^^^^^^^^^^^

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

[[fifo_plugin]]
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:

* nick change on IRC server freenode to "newnick":

----------------------------------------
$ echo 'irc.server.freenode */nick newnick' >~/.weechat/weechat_fifo_12345
----------------------------------------

* display text on IRC #weechat channel:

----------------------------------------
$ echo 'irc.freenode.#weechat *hello!' >~/.weechat/weechat_fifo_12345
----------------------------------------

* display text on current buffer:

----------------------------------------
$ echo '*hello!' >~/.weechat/weechat_fifo_12345
----------------------------------------

* send two commands to unload/reload Python scripts (you have to separate them
  with "\n"):

----------------------------------------
$ echo -e '*/python unload\n*/python autoload' >~/.weechat/weechat_fifo_12345
----------------------------------------

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

[source,shell]
----------------------------------------
#!/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'
----------------------------------------

[[irc_plugin]]
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,Xfer plugin>>).

[[irc_ssl_certificates]]
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.

[[irc_connect_oftc_with_certificate]]
First example: connect to oftc and check certificate
++++++++++++++++++++++++++++++++++++++++++++++++++++

* Import certificate in shell:

----------------------------------------
$ mkdir -p ~/.weechat/ssl
$ wget -O ~/.weechat/ssl/CAs.pem http://www.spi-inc.org/ca/spi-cacert.crt
----------------------------------------

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

* In WeeChat, with "oftc" server already created:

----------------------------------------
/connect oftc
----------------------------------------

[[irc_connect_oftc_with_certfp]]
Second example: connect to oftc using CertFP
++++++++++++++++++++++++++++++++++++++++++++

* Create certificate in shell:

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

* In WeeChat, with "oftc" server already created:

----------------------------------------
/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

[[irc_sasl_authentication]]
SASL authentication
^^^^^^^^^^^^^^^^^^^

WeeChat supports SASL authentication, using different mechanisms:

* 'plain': plain text password
* 'dh-blowfish': blowfish encrypted password
* 'dh-aes': AES encrypted password
* 'external': client side SSL cert

Options in servers are:

* 'sasl_mechanism': mechanism to use (see above)
* 'sasl_timeout': timeout (in seconds) for authentication
* 'sasl_username': username (nick)
* 'sasl_password': password

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

----------------------------------------
/set irc.server_default.sasl_mechanism dh-blowfish
----------------------------------------

[NOTE]
The "gcrypt" library is required when compiling WeeChat in order to use
"dh-blowfish" and "dh-aes" mechanisms (see <<dependencies,dependencies>>).

[[irc_tor_freenode]]
Connect to Freenode with TOR/SASL
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

In addition to SSL, Freenode servers support connections with TOR
(https://www.torproject.org/), a network of virtual tunnels that allows people
and groups to improve their privacy and security on the Internet.

First, make sure to have WeeChat compiled with <<dependencies,libgcrypt11-dev>>
(if built from sources); it's not mandatory, but "dh-blowfish" ensures stronger
security compared to "plain" authentication system with SASL.

In first place, install TOR. For Debian (and derived):

----------------------------------------
$ sudo apt-get install tor
----------------------------------------

In WeeChat you need to create a socks5 proxy for TOR service (hostname/IP and
port depend on your TOR configuration):

----------------------------------------
/proxy add tor socks5 127.0.0.1 9050
----------------------------------------

Now, create a new server, for example:

----------------------------------------
/server add freenode-tor p4fsi4ockecnea7l.onion
----------------------------------------

Set proxy for TOR:

----------------------------------------
/set irc.server.freenode-tor.proxy "tor"
----------------------------------------

Set SASL authentication:

----------------------------------------
/set irc.server.freenode-tor.sasl_mechanism dh-blowfish
/set irc.server.freenode-tor.sasl_username "your_nickname"
/set irc.server.freenode-tor.sasl_password "your_password"
----------------------------------------

And finally, connection to server:

----------------------------------------
/connect freenode-tor
----------------------------------------

For more info about Freenode and TOR: http://freenode.net/irc_servers.shtml#tor

[[irc_smart_filter_join_part_quit]]
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.

[[irc_ctcp_replies]]
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:

[[irc_target_buffer]]
Target buffer for IRC messages
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

It is possible to customize target buffer for IRC messages (buffer used to
display message) with options `irc.msgbuffer.*`.

For some IRC messages (see list below), you can use value:

current::
    current buffer (if it's IRC buffer, or on server buffer by default)

private::
    private buffer for nick, or current/server buffer if not found (according
    to option 'irc.look.msgbuffer_fallback')

server::
    server buffer

weechat::
    WeeChat "core" buffer

When option is not set (default), WeeChat chooses appropriate buffer, commonly
server or channel buffer.

Other numeric commands can be customized as well.

Message can be prefixed by server name to be specific to an irc server
(for example: `freenode.whois`).

Some examples:

* display result of `/whois` on private buffer:

----------------------------------------
/set irc.msgbuffer.whois private
----------------------------------------

* restore default buffer for whois (server buffer):

----------------------------------------
/unset irc.msgbuffer.whois
----------------------------------------

* display invitation on current buffer, only for "freenode" server:

----------------------------------------
/set irc.msgbuffer.freenode.invite current
----------------------------------------

* display message "303" (ison) on WeeChat "core" buffer:

----------------------------------------
/set irc.msgbuffer.303 weechat
----------------------------------------

[[logger_log_levels]]
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:

* level 1: message from user (on channel or private)
* level 2: nick change (you or someone else)
* level 3: any server message (except join/part/quit)
* level 4: server message join/part/quit

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

Some examples:

* set level 3 for IRC channel #weechat:

----------------------------------------
/set logger.level.irc.freenode.#weechat 3
----------------------------------------

* set level 3 for freenode server buffer:

----------------------------------------
/set logger.level.irc.server.freenode 3
----------------------------------------

* set level 3 for all channels on server freenode:

----------------------------------------
/set logger.level.irc.freenode 3
----------------------------------------

* set level 2 for all IRC buffers:

----------------------------------------
/set logger.level.irc 2
----------------------------------------

[[logger_filenames_masks]]
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, on buffer "irc.freenode.#weechat", WeeChat will search a mask with
option name, in this order:

----------------------------------------
logger.mask.irc.freenode.#weechat
logger.mask.irc.freenode
logger.mask.irc
logger.file.mask
----------------------------------------

That means you can have masks specific for some IRC servers
("logger.mask.irc.freenode") or for a plugin ("logger.mask.irc").

[[logger_files_by_date]]
Log files by date
+++++++++++++++++

To have log files by date, you can use date/time specifiers in mask (see
`man strftime` for formats), for example:

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

You'll have following files:

........................................
~/.weechat/
    |--- logs/
        |--- 2010/
            |--- 11/
            |       irc.server.freenode.weechatlog
            |       irc.freenode.#weechat.weechatlog
        |--- 2010/
            |--- 12/
            |       irc.server.freenode.weechatlog
            |       irc.freenode.#weechat.weechatlog
........................................

[[logger_irc_files_by_server_channel]]
IRC log files by server and channel
+++++++++++++++++++++++++++++++++++

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

[[relay_plugin]]
Relay plugin
~~~~~~~~~~~~

The Relay plugin is used to relay data via network, using different protocols:

* 'irc': IRC proxy: used to share connections to IRC servers with one or many
  other IRC clients
* 'weechat': protocol used by remote interfaces to display and interact with
  WeeChat (for example QWeeChat or weechat-android)

Password
^^^^^^^^

It is highly recommended to set a password for relay, with command:

----------------------------------------
/set relay.network.password "mypass"
----------------------------------------

This password is used for 'irc' and 'weechat' protocols.

[[relay_ssl]]
SSL
^^^

You can use SSL by creating a certificate and private key, and by using prefix
"ssl." in the name of protocol.

The default file for certificate/key is '~/.weechat/ssl/relay.pem'
(option <<option_relay.network.ssl_cert_key,relay.network.ssl_cert_key>>).

You can create a certificate and private key 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
----------------------------------------

If WeeChat is already running, you can reload the certificate and private key
with command:

----------------------------------------
/relay sslcertkey
----------------------------------------

[[relay_irc_proxy]]
IRC proxy
^^^^^^^^^

The Relay plugin can act as an IRC proxy: it will simulate an IRC server, and
you can connect to WeeChat with any other IRC client (including WeeChat itself).

You can define one port by IRC server, or one generic port for all servers.

When using one port for all servers, the client must send the internal name of
server in the IRC "PASS" command, with this format:

----------------------------------------
PASS server:password
----------------------------------------

Example: IRC proxy with SSL for any server (client will choose):

----------------------------------------
/relay add ssl.irc 8000
----------------------------------------

Example: IRC proxy without SSL only for server "freenode":

----------------------------------------
/relay add irc.freenode 8000
----------------------------------------

Now you can connect on port 8000 with any IRC client using server password
"mypass" (or "freenode:mypass" if no server was specified in the relay).

[[relay_weechat_protocol]]
WeeChat protocol
^^^^^^^^^^^^^^^^

The Relay plugin can send data to remote interface using WeeChat protocol.

For example:

----------------------------------------
/relay add weechat 9000
----------------------------------------

Now you can connect on port 9000 with a remote interface using password
"mypass".

[[relay_websocket]]
WebSocket
^^^^^^^^^

WebSocket protocol (http://tools.ietf.org/html/rfc6455[RFC 6455]) is supported
in Relay plugin for all protocols.

The WebSocket handshake is automatically detected and socket becomes ready for
WebSocket if required headers are found in handshake and if origin is allowed
(see option
<<option_relay.network.websocket_allowed_origins,relay.network.websocket_allowed_origins>>).

A WebSocket can be opened in a HTML5 with a single line of JavaScript:

[source,js]
----------------------------------------
websocket = new WebSocket("ws://server.com:9000/weechat");
----------------------------------------

The port (9000 in example) is the port defined in Relay plugin.
The URI must always end with "/weechat" (for 'irc' and 'weechat' protocols).

[[rmodifier_plugin]]
Rmodifier plugin
~~~~~~~~~~~~~~~~

The Rmodifier plugin lets you alter modifier strings using regular expressions.
Typical use is to hide password when you type them, or when WeeChat saves
them in command history. For example, it is possible to replace each char in
these passwords by `*`.

[[rmodifier_creation]]
Rmodifier creation
^^^^^^^^^^^^^^^^^^

A rmodifier consists of three elements:

. one or more "modifiers"
. a regular expression, to capture "groups"
. a string that describes output using number of "groups" captured in regular
  expression

For list of modifiers used by WeeChat or plugins, see
'WeeChat Plugin API Reference', function 'weechat_hook_modifier'.

For each captured group, following actions are possible:

* keep group as-is (by using group number)
* replace all chars in group to hide content (group number + `*`)
* remove group (if group is not used in string)

Example of default rmodifier for command `/oper`:

* modifiers: `history_add,input_text_display`
** `history_add`: called when WeeChat stores command in history
** `input_text_display`: called when command line has changed
   (applies only on display, not content of command line)
* regular expression: `^(/oper +\S+ +)(.*)`
* groups: `1,2*`

Each time modifiers "history_add" or "input_text_display" are called, regular
expression is checked. If string matches, then it is replaced by captured groups,
as defined in string with groups.

In this example, we keep number 1 as-is, and we replace all chars of group 2 by
replacement char defined in configuration (option 'rmodifier.look.hide_char').

If command line contains: `/oper nick password` then display becomes:
`/oper nick ********`.

[[scripts_plugins]]
Scripts plugins
~~~~~~~~~~~~~~~

WeeChat provides 6 scripting plugins: Python, Perl, Ruby, Lua, Tcl and Guile
(scheme).
These plugins can load, execute and unload scripts for these languages.

Another plugin called "script" is a scripts manager and is used to load/unload
scripts of any language, and install/remove scripts of WeeChat scripts
repository, which are visible at this URL: http://weechat.org/scripts

For more information about how to write scripts, or WeeChat API for
scripts, please read 'WeeChat Scripting Guide'.
