#### 2.2.3. Compile with autotools

| 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
    $ mkdir build
    $ cd build
    $ ../configure
    $ make
    $ sudo make install

- Installation in custom directory (for example your home):

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

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

    $ ./configure --help

#### 2.2.4. Run tests

Following packages are required to compile tests:

- libcpputest-dev

- C++ compiler

Tests must be enabled when compiling WeeChat (with CMake):

    $ cmake .. -DENABLE_TESTS=ON

They can be launched after compilation from the build directory (with CMake):

    $ ctest -V

### 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 https://github.com/weechat/weechat.git

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:

- Compile it with debug info (or install binary package with debug info).

- Enable core files on your system.

- Install gdb.

#### 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 can use option 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

#### 2.4.3. Get backtrace with gdb

When WeeChat crashes, your system will create a file core or core.12345 (12345 is process id) if the option is enabled. 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

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
    #1  0x00007f9dfb04b8e6 in abort () from /lib/libc.so.6
    #2  0x0000000000437f66 in weechat_shutdown (return_code=1, crash=1)
        at /some_path/src/core/weechat.c:351
    #3  <signal handler called>
    #4  0x000000000044cb24 in hook_process_timer_cb (arg_hook_process=0x254eb90,
        remaining_calls=<value optimized out>) at /some_path/src/core/wee-hook.c:1364
            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!

#### 2.4.4. 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

## 3. Usage

### 3.1. Running WeeChat

To start WeeChat, issue this command:

    $ weechat

When you run WeeChat for the first time, the default configuration files are created in ~/.weechat with default options and values (see Files and directories).

#### 3.1.1. Command line options

-a, --no-connect

  Disable auto-connect to servers when WeeChat is starting.

-c, --colors

  Display default colors in terminal.

--daemon

  Run WeeChat in background, as a daemon (works only with the command weechat-headless).

-d, --dir <path>

  Set path as home for WeeChat (used for configuration files, logs, user plugins and scripts), default value is "~/.weechat" (note: directory is created if not found by WeeChat). If this option is not given, the environment variable WEECHAT_HOME is used (if not empty).

-t, --temp-dir

  Create a temporary WeeChat home directory and delete it on exit (incompatible with option "-d").
  The name of the directory is automatically built by WeeChat, with this template: "weechat_temp_XXXXXX" (where "XXXXXX" is random). It it created in the first available directory in this list: environment variable "TMPDIR", "/tmp" (may be different according to the operating system), environment variable "HOME", current directory.
  The temporary home directory has permissions 0700 (only owner can read, write and execute).

-h, --help

  Display help.

-l, --license

  Display WeeChat license.

-p, --no-plugin

  Disable plugins auto-load.

-P, --plugins <plugins>

  Load only these plugins at startup (see /help weechat.plugin.autoload). If this option is given, the option weechat.plugin.autoload is not used.

-r, --run-command <command>

  Run command(s) after startup; many commands can be separated by semicolons, this option can be given multiple times.

-s, --no-script

  Disable scripts auto-load.

--upgrade

  Upgrade WeeChat using session files generated with command `/upgrade -quit`.

-v, --version

  Display WeeChat version.

plugin:option

  Option for a plugin.

#### 3.1.2. Extra debug options

| These options are for debug purposes only, DO NOT USE IN PRODUCTION!

--no-dlclose

  Do not call the function dlclose after plugins are unloaded. This is useful with tools like Valgrind to display stack for unloaded plugins.

--no-gnutls

  Do not call the init and deinit functions of GnuTLS library. This is useful with tools like Valgrind and electric-fence, to prevent GnuTLS memory errors.

--no-gcrypt

  Do not call the init and deinit functions of Gcrypt library. This is useful with tools like Valgrind, to prevent Gcrypt memory errors.

The files in the WeeChat home directory are:

File | Description | Sensitive data
--- | --- | ---
`weechat.conf` | Main WeeChat configuration file | Possible (example: list of channels in a saved buffers layout).
`sec.conf` | Configuration file with secured data | Yes, highly sensitive: this file must never be shared with anyone.
`plugins.conf` | Plugins configuration file | Possible, depends on plugins/scripts.
`alias.conf` | Configuration file for alias plugin | Possible, depends on aliases.
`buflist.conf` | Configuration file for buflist plugin | No.
`charset.conf` | Configuration file for charset plugin | No.
`exec.conf` | Configuration file for exec plugin | No.
`fifo.conf` | Configuration file for fifo plugin | No.
`fset.conf` | Configuration file for fset plugin | No.
`guile.conf` | Configuration file for guile plugin | No.
`irc.conf` | Configuration file for irc plugin | Yes: it can contain passwords for servers, nickserv and channels (if not stored in `sec.conf`).
`javascript.conf` | Configuration file for javascript plugin | No.

### 3.5. Command line

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

#### 3.5.1. 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

#### 3.5.2. Color codes

For some plugins like IRC, you can use color codes and attributes, as follow (press `Ctrl`+`c` then following letter, with optional value):

Key | Description
--- | ---
`Ctrl`+`c`, `b` | Bold text.
`Ctrl`+`c`, `c`, `xx` | Text color `xx` (see list of colors below).
`Ctrl`+`c`, `c`, `xx`, `,`, `yy` | Text color `xx` and background `yy` (see list of colors below).
`Ctrl`+`c`, `i` | Italic text.
`Ctrl`+`c`, `o` | Disable color and attributes.
`Ctrl`+`c`, `v` | Reverse video (revert text color with background).
`Ctrl`+`c`, `_` | Underlined text.

| The same code (without number for `Ctrl`+`c`, `c`) can be used to stop the attribute.

Color codes for `Ctrl`+`c`, `c` are:

| To show all available colors in your terminal, you can do `/color` then `Alt`+`c` in WeeChat or run this command in terminal: `weechat --colors`.

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

    ^Cc12^Cbhello ^Cb^Cc04^C_everybody^C_^Cc!

| In irc plugin, you can remap these colors using option irc.color.mirc_remap.

### 3.6. Colors

WeeChat can use up to 32767 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:

$TERM | Colors | Pairs
--- | --- | ---
"rxvt-unicode", "xterm", …​ | 88 | 32767
"rxvt-256color", "xterm-256color", …​ | 256 | 32767
"screen" | 8 | 64
"screen-256color" | 256 | 32767
"tmux" | 8 | 64
"tmux-256color" | 256 | 32767

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

- under tmux: screen-256color or tmux-256color

- outside screen/tmux: xterm-256color, rxvt-256color, putty-256color, …​

| 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, you can change it with these two commands:

    /set env TERM screen-256color
    /upgrade

#### 3.6.1. Basic colors

Basic colors in WeeChat are:

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

#### 3.6.2. 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 `Alt`+`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

#### 3.6.3. 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

#### 3.6.4. 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

- `/`: italic

- `_`: underlined text

- `|`: keep attributes: do not reset bold/reverse/italic/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

### 3.7. Buffers and windows

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 messages

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`):

                                   ▼ window #2 (buffer #4)

### 3.8. Buffers lines

#### 3.8.1. Format of lines

Lines displayed in formatted buffers have following fields:

Field | Displayed | Description
--- | --- | ---
date/time (message) | Yes | Date/time of message (may be past).
date/time (print) | No | Date/time when WeeChat prints the message.
prefix | Yes | Prefix of message, commonly a nick.
message | Yes | The message itself.
displayed | No | Boolean: true if line is displayed, false if line is filtered with command /filter.
highlight | No | Boolean: true if line has a highlight, false otherwise.
tags | With `/debug tags` | Tags associated with the line (see lines tags).

The display of lines can be customized with many look options (weechat.look.*) and color options (weechat.color.chat_*).

#### 3.8.2. Lines tags

WeeChat uses tags in lines for different purposes:

- highlight

- notify level

- logging

- use of command /filter

Tags can be displayed with the command `/debug tags` (same command to hide them).

Tags commonly used (non-exhaustive list):

Tag | Description
--- | ---
`no_filter` | Line can not be filtered.
`no_highlight` | No highlight is possible on line.
`no_log` | Line is not written in log file.
`log0 …​ log9` | Level of log for line (see `/help logger`).
`notify_none` | Buffer with line is not added to hotlist.
`notify_message` | Buffer with line is added to hotlist with level "message".
`notify_private` | Buffer with line is added to hotlist with level "private".
`notify_highlight` | Buffer with line is added to hotlist with level "highlight".
`self_msg` | Self message.
`nick_xxx` | Message is from nick "xxx".
`prefix_nick_ccc` | Prefix is a nick with color "ccc".
`host_xxx` | Username and host in message.
`irc_xxx` | IRC message "xxx" (can be a command or a 3-digits number).
`irc_numeric` | IRC numeric message.
`irc_error` | Error from IRC server.
`irc_action` | Action from a nick (command `/me`).
`irc_ctcp` | CTCP message.
`irc_ctcp_reply` | Reply to CTCP message.
`irc_smart_filter` | IRC message that can be filtered with the "smart filter".
`away_info` | Message with away info.

### 3.9. 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:

Option | Values | Description
--- | --- | ---
`type` | `root`, `window` | A bar with type `root` is displayed exactly one time on screen, outside all windows. The default bar buflist has type `root`. 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 default bars title, status, input and 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 /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 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 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 filling for more info).
`conditions` | string | The conditions to display the bar (see conditions for more info).

#### 3.9.1. 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"

#### 3.9.2. 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:

#### 3.9.3. Conditions

The option conditions is a string which is evaluated to know if the bar must be displayed or not.

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 /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)"

### 3.10. Bare display

A special display, called "bare display" can be used for easy click on long URLs and selection of text (using the mouse).

The bare display has following features:

- It displays only the content of current buffer: no window split neither bars (no title, nicklist, status, input, …​).

- The WeeChat mouse support is disabled (if it was enabled): you can use your mouse like you do in the terminal to click on URLs and select text.

- Ncurses is not used, therefore URLs are not cut at the end of lines.

The default key to enable bare display is `Alt`+`l` (`L`), and same key to exit (or by default anything changing the input will exit the bare display, see option weechat.look.bare_display_exit_on_input).

The time format can be customized with the option weechat.look.bare_display_time_format.

The bare display can be enabled for a specific delay using the command /window.

If WeeChat looks like that:

So you can click the URL from joe without any problem in your terminal (of course this supposes that your terminal supports click on URLs).

### 3.11. Notify levels

#### 3.11.1. Setup 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 weechat.look.buffer_notify_default, default is all.

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

#### 3.11.2. Max hotlist level for nicks

It is possible to set max hotlist level for some nicks, per buffer, or per group of buffers (like IRC servers).

The buffer property "hotlist_max_level_nicks" can be set with a list of nicks and for each nick the max hotlist level to trigger, possible levels are:

- -1: no hotlist changes for nick

- 0: low priority (like join/part messages)

- 1: message

- 2: private message

- 3: highlight (in fact useless, since it’s already the default max for all messages)

For example to disable highlights from "joe" and "mike" on current buffer:

    /buffer set hotlist_max_level_nicks_add joe:2,mike:2

| The buffer property "hotlist_max_level_nicks" is not saved in configuration. You can easily save it with the script buffer_autoset.py: you can install it with `/script install buffer_autoset.py` and get help with `/help buffer_autoset`.

### 3.12. Highlights

#### 3.12.1. Add words to highlight

By default, WeeChat highlights messages from other users containing your nick, therefore the highlight depends on the buffer (the nick can be different from one buffer to another).

You can add other words to highlight with the option weechat.look.highlight, for example to highlight your nick and "word1", "word2" and all words beginning with "test":

    /set weechat.look.highlight word1,word2,test*

If you need a more specific rule for the word, you can use regular expressions with the option weechat.look.highlight_regex, for example to highlight words "flashcode", "flashcöde" and "flashy":

    /set weechat.look.highlight_regex flashc[oö]de|flashy

The delimiters around words to highlight can be customized with the option weechat.look.word_chars_highlight.

#### 3.12.2. Add tags to highlight

Lines displayed can contain "tags", which give some info about the origin of message or the message itself.
You can display tags with the command `/debug tags` (same command to hide them).

You can add specific tags to highlight with the option weechat.look.highlight_tags. Tags are separated by commas, and multiple tags can be separated by `+` to do a logical "and" between them.

For example to highlight all messages from nick "FlashCode" and all notices from nicks beginning with "toto":

    /set weechat.look.highlight_tags "nick_flashcode,irc_notice+nick_toto*"

#### 3.12.3. Set extra highlights on buffer

You can force highlight using a regular expression with the buffer property "highlight_regex".

For example to force the highlight on all messages in the current buffer:

    /buffer set highlight_regex .*

| The buffer property "highlight_regex" is not saved in configuration. You can easily save it with the script buffer_autoset.py: you can install it with `/script install buffer_autoset.py` and get help with `/help buffer_autoset`.

To enable mouse now, press `Alt`+`m` or do following command:

    /mouse enable

It is possible to temporarily disable mouse, and bind that on a key. For example key `Alt`+`%` to disable mouse for 10 seconds:

    /key bind meta-% /mouse toggle 10

| When mouse is enabled in WeeChat, all mouse events are caught by WeeChat, so actions such as copy/paste or clicks on URLs are not sent to the terminal. Using `Shift` key causes the events to be sent directly to the terminal, as if the mouse was disabled (on some terminals like iTerm, you have to use `Alt` instead of `Shift`).

| For any problem with mouse, please look at WeeChat FAQ / Mouse.

#### 3.14.2. Bind mouse events to commands

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

You can change or add bindings with the command `/key` using context "mouse" (for syntax, see 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:

Modifier | Description
--- | ---
`ctrl` | Key `Ctrl`
`alt` | Key `Alt`
`ctrl-alt` | Keys `Ctrl` + `Alt`

List of buttons/wheel:

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):

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):

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`

- …​

| 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.

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

### 3.15. Secured data

#### 3.15.1. Storage

WeeChat can encrypt passwords or private data using secured data, stored in file sec.conf.

This configuration file is read before any other file, and the values stored inside can be used in various WeeChat or plugins/scripts options.

You can set a passphrase to encrypt data in sec.conf. This is not mandatory but highly recommended, otherwise data is stored as plain text in file.

    /secure passphrase this is my passphrase

When a passphrase is set, WeeChat will ask you to enter it on startup (but not on `/upgrade`).

You can change this behavior and use a file with the passphrase (see option sec.crypt.passphrase_file).

##### Encryption

The encryption of data is made in 3 steps:

1. Derive a key from the passphrase (with optional salt).

2. Compute hash of data to encrypt.

3. Encrypt the hash + data (output is: salt + encrypted hash/data).

| The cipher block mode is CFB.

The result is put as hexadecimal string in file sec.conf, for example:

    [data]
    __passphrase__ = on
    freenode = "53B1C86FCDA28FC122A95B0456ABD79B5AB74654F21C3D099A6CCA8173239EEA59533A1D83011251F96778AC3F5166A394"

##### Decryption

The decryption of data is made in 3 steps:

1. Derive a key using salt and passphrase.

2. Decrypt hash + data.

3. Check that decrypted hash == hash of data.

#### 3.15.2. Manage secured data

To add secured data, use `/secure set`, for example a password for freenode IRC server:

    /secure set freenode mypassword

For comfort, secured data can be displayed in a dedicated buffer (`Alt`+`v` on buffer to see values), just do:

    /secure

Secured data can be used in some options that can contain private data like password, using this format: "${sec.data.xxx}" where "xxx" is the name of secured data (used with `/secure set xxx …​`).
For a complete list of supported options, see `/help secure`.

To use the freenode password, for example with SASL authentication:

    /set irc.server.freenode.sasl_password "${sec.data.freenode}"

            -n: display result without sending it to buffer (debug mode)
            -s: split expression before evaluating it (many commands can be separated by semicolons)
            -c: evaluate as condition: use operators and parentheses, return a boolean value ("0" or "1")
    expression: expression to evaluate, variables with format ${variable} are replaced (see below); many commands can be separated by semicolons
      operator: a logical or comparison operator:
                - logical operators:
                    &&  boolean "and"
                    ||  boolean "or"

                    !=  not equal
                    <=  less or equal
                    <   less
                    >=  greater or equal
                    >   greater
                    =~  is matching POSIX extended regex
                    !~  is NOT matching POSIX extended regex
                    =*  is matching mask (wildcard "*" is allowed)
                    !*  is NOT matching mask (wildcard "*" is allowed)

    An expression is considered as "true" if it is not NULL, not empty, and different from "0".
    The comparison is made using floating point numbers if the two expressions are valid numbers, with one of the following formats:
      - integer (examples: 5, -7)
      - floating point number (examples: 5.2, -7.5, 2.83e-2)
      - hexadecimal number (examples: 0xA3, -0xA3)
    To force a string comparison, you can add double quotes around each expression, for example:
      50 > 100      ==> 0
      "50" > "100"  ==> 1

    Some variables are replaced in expression, using the format ${variable}, variable can be, by order of priority:
      1. an evaluated sub-string (format: "eval:xxx")
      2. a string with escaped chars (format: "esc:xxx" or "\xxx")
      3. a string with chars to hide (format: "hide:char,string")
      4. a string with max chars (format: "cut:max,suffix,string" or "cut:+max,suffix,string")
         or max chars displayed on screen (format: "cutscr:max,suffix,string" or "cutscr:+max,suffix,string")
      5. a reversed string (format: "rev:xxx")
      6. a repeated string (format: "repeat:count,string")
      7. a color (format: "color:xxx", see "Plugin API reference", function "color")
      8. an info (format: "info:name,arguments", arguments are optional)
      9. current date/time (format: "date" or "date:format")
      10. an environment variable (format: "env:XXX")
      11. a ternary operator (format: "if:condition?value_if_true:value_if_false")
      12. an option (format: "file.section.option")
      13. a local variable in buffer
      14. a hdata name/variable (the value is automatically converted to string), by default "window" and "buffer" point to current window/buffer.
    Format for hdata can be one of following:
      hdata.var1.var2...: start with a hdata (pointer must be known), and ask variables one after one (other hdata can be followed)
      hdata[list].var1.var2...: start with a hdata using a list, for example:
        ${buffer[gui_buffers].full_name}: full name of first buffer in linked list of buffers
        ${plugin[weechat_plugins].name}: name of first plugin in linked list of plugins
      hdata[pointer].var1.var2...: start with a hdata using a pointer, for example:
        ${buffer[0x1234abcd].full_name}: full name of the buffer with this pointer (can be used in triggers)
    For name of hdata and variables, please look at "Plugin API reference", function "weechat_hdata_get".

    Examples (simple strings):
      /eval -n ${info:version}                       ==> 0.4.3

        rename: rename a filter
           del: delete a filter
          -all: delete all filters
        buffer: comma separated list of buffers where filter is active:
                - this is full name including plugin (example: "irc.freenode.#weechat" or "irc.server.freenode")
                - "*" means all buffers
                - a name starting with '!' is excluded
                - wildcard "*" is allowed
       tags: comma separated list of tags, for example "irc_join,irc_part,irc_quit"
                - logical "and": use "+" between tags (for example: "nick_toto+irc_action")
                - wildcard "*" is allowed
                - if tag starts with '!', then it is excluded and must NOT be in message
      regex: POSIX extended regular expression to search in line
                - use '\t' to separate prefix from message, special chars like '|' must be escaped: '\|'
                - if regex starts with '!', then matching result is reversed (use '\!' to start with '!')
                - two regular expressions are created: one for prefix and one for message
                - regex are case insensitive, they can start by "(?-i)" to become case sensitive

    The default key alt+'=' toggles filtering on/off globally and alt+'-' toggles filtering on/off in the current buffer.

    Tags most commonly used:
      no_filter, no_highlight, no_log, log0..log9 (log level),
      notify_none, notify_message, notify_private, notify_highlight,
      self_msg, nick_xxx (xxx is nick in message), prefix_nick_ccc (ccc is color of nick),
      host_xxx (xxx is username + host in message),
      irc_xxx (xxx is command name or number, see /server raw or /debug tags),
      irc_numeric, irc_error, irc_action, irc_ctcp, irc_ctcp_reply, irc_smart_filter, away_info.
    To see tags for lines in buffers: /debug tags

    Examples:
      use IRC smart filter on all buffers:
        /filter add irc_smart * irc_smart_filter *
      use IRC smart filter on all buffers except those with "#weechat" in name:
        /filter add irc_smart *,!*#weechat* irc_smart_filter *
      filter all IRC join/part/quit messages:
        /filter add joinquit * irc_join,irc_part,irc_quit *

      filter IRC join/action messages from nick "toto":
        /filter add toto * nick_toto+irc_join,nick_toto+irc_action *
      filter lines containing "weechat sucks" on IRC channel #weechat:
        /filter add sucks irc.freenode.#weechat * weechat sucks
      filter lines that are strictly equal to "WeeChat sucks" on all buffers:

          bind <key> [<command> [<args>]]
          bindctxt <context> <key> [<command> [<args>]]
          unbind <key>
          unbindctxt <context> <key>
          reset <key>
          resetctxt <context> <key>
          resetall -yes [<context>]
          missing [<context>]

           list: list all current keys (without argument, this list is displayed)
    listdefault: list default keys
       listdiff: list differences between current and default keys (keys added, redefined or deleted)
        context: name of context ("default" or "search")
           bind: bind a command to a key or display command bound to key (for context "default")
       bindctxt: bind a command to a key or display command bound to key, for given context
        command: command (many commands can be separated by semicolons)
         unbind: remove a key binding (for context "default")
     unbindctxt: remove a key binding for given context
          reset: reset a key to default binding (for context "default")
      resetctxt: reset a key to default binding, for given context
       resetall: restore bindings to the default values and delete ALL personal bindings (use carefully!)
        missing: add missing keys (using default bindings), useful after installing new WeeChat version

    When binding a command to a key, it is recommended to use key alt+k (or Esc then k), and then press the key to bind: this will insert key code in command line.

    For context "mouse" (possible in context "cursor" too), key has format: "@area:key" or "@area1>area2:key" where area can be:
              *: any area on screen
           chat: chat area (any buffer)
      chat(xxx): chat area for buffer with name "xxx" (full name including plugin)
         bar(*): any bar
       bar(xxx): bar "xxx"
        item(*): any bar item
      item(xxx): bar item "xxx"
    Wildcard "*" is allowed in key to match many mouse events.
    A special value for command with format "hsignal:name" can be used for context mouse, this will send the hsignal "name" with the focus hashtable as argument.
    Another special value "-" can be used to disable key (it will be ignored when looking for keys).

    Examples:
      key alt-t to toggle nicklist bar:
        /key bind meta-t /bar toggle nicklist
      key alt-r to jump to #weechat IRC channel:
        /key bind meta-r /buffer #weechat
      restore default binding for key alt-r:
        /key reset meta-r
      key "tab" to stop search in buffer:
        /key bindctxt search ctrl-I /input search_stop
      middle button of mouse on a nick to retrieve info on nick:
        /key bindctxt mouse @item(buffer_nicklist):button3 /msg nickserv info ${nick}

       name: name for stored layout (default is "default")
    buffers: store/apply only buffers (order of buffers)
    windows: store/apply only windows (buffer displayed by each window)

    Without argument, this command displays stored layouts.

    The current layout can be saved on /quit command with the option "weechat.look.save_layout_on_exit".

        /mouse enable
      toggle mouse for 5 seconds:
        /mouse toggle 5

         -yes: required if option "weechat.look.confirm_quit" is enabled
    arguments: text sent with signal "quit"
               (for example irc plugin uses this text to send quit message to server)

    By default when quitting the configuration files are saved (see option "weechat.look.save_config_on_exit") and the current layout can be saved (see option "weechat.look.save_layout_on_exit").

- `reload`: reload configuration files from disk

    /reload  [<file> [<file>...]]

    file: configuration file to reload (without extension ".conf")

    Without argument, all files (WeeChat and plugins) are reloaded.

- `repeat`: execute a command several times

    Example:
      scroll 2 pages up:
        /repeat 2 /window page_up

- `save`: save configuration files to disk

    /save  [<file> [<file>...]]

    By default all configuration files are saved to disk on /quit command (see option "weechat.look.save_config_on_exit").

- `secure`: manage secured data (passwords or private data encrypted in file sec.conf)

    /secure  passphrase <passphrase>|-delete
             decrypt <passphrase>|-discard
             set <name> <value>
             del <name>

    passphrase: change the passphrase (without passphrase, data is stored as plain text in file sec.conf)
       -delete: delete passphrase
       decrypt: decrypt data still encrypted (it happens only if passphrase was not given on startup)
      -discard: discard all data still encrypted
           set: add or change secured data
           del: delete secured data

    Without argument, this command displays secured data in a new buffer.

    Keys on secure buffer:
      alt+v  toggle values

    When a passphrase is used (data encrypted), it is asked by WeeChat on startup.
    It is possible to set environment variable "WEECHAT_PASSPHRASE" to prevent the prompt (this same variable is used by WeeChat on /upgrade), or to set option sec.crypt.passphrase_file to read the passphrase from a file (see /help sec.crypt.passphrase_file).

    Secured data with format ${sec.data.xxx} can be used in:
      - command /eval
      - command line argument "--run-command"
      - options weechat.startup.command_{before|after}_plugins
      - other options that may contain a password or sensitive data (for example proxy, irc server and relay); see /help on the options to check if they are evaluated.

    Examples:
      set a passphrase:
        /secure passphrase this is my passphrase
      encrypt freenode SASL password:
        /secure set freenode mypassword
        /set irc.server.freenode.sasl_password "${sec.data.freenode}"
      encrypt oftc password for nickserv:
        /secure set oftc mypassword
        /set irc.server.oftc.command "/msg nickserv identify ${sec.data.oftc}"
      alias to ghost the nick "mynick":
        /alias add ghost /eval /msg -server freenode nickserv ghost mynick ${sec.data.freenode}

- `set`: set config options and environment variables

    /set  [<option> [<value>]]
          diff [<option> [<option>...]]
          env [<variable> [<value>]]

    option: name of an option (wildcard "*" is allowed to list options, if no value is specified)
     value: new value for option, according to type:
              boolean: on, off or toggle
              integer: number, ++number or --number
               string: any string ("" for empty string)
                color: color name, ++number or --number
            Note: for all types, you can use null to remove option value (undefined value). This works only for some special plugin variables.
      diff: display only changed options
       env: display or set an environment variable (use value "" to unset a variable)

    Examples:
      display options about highlight:
        /set *highlight*
      add a word to highlight:
        /set weechat.look.highlight "word"
      display changed options:
        /set diff
      display changed options in irc plugin:
        /set diff irc.*
      display value of environment variable LANG:
        /set env LANG
      set environment variable LANG and use it:
        /set env LANG fr_FR.UTF-8
        /upgrade
      unset environment variable ABC:
        /set env ABC ""

- `unset`: unset/reset config options

    /unset  <option>
            -mask <option>

    option: name of an option
     -mask: use a mask in option (wildcard "*" is allowed to mass-reset options, use carefully!)

    According to option, it's reset (for standard options) or removed (for optional settings, like server values).

    Examples:
      reset one option:
        /unset weechat.look.item_time_format
      reset all color options:
        /unset -mask weechat.color.*

- `upgrade`: reload the WeeChat binary without disconnecting from servers

    /upgrade  [-yes] [<path_to_binary>|-quit]

              -yes: required if option "weechat.look.confirm_upgrade" is enabled
    path_to_binary: path to WeeChat binary (default is current binary)
            -dummy: do nothing (option used to prevent accidental completion with "-quit")
             -quit: close *ALL* connections, save session and quit WeeChat, which makes possible a delayed restoration (see below)

    This command upgrades and reloads a running WeeChat session. The new WeeChat binary must have been compiled or installed with a package manager before running this command.

    Note: SSL connections are lost during upgrade, because reload of SSL sessions is currently not possible with GnuTLS. There is automatic reconnection after upgrade.

    Upgrade process has 4 steps:
      1. save session into files for core and plugins (buffers, history, ..)
      2. unload all plugins (configuration files (*.conf) are written on disk)
      3. save WeeChat configuration (weechat.conf)
      4. execute new WeeChat binary and reload session.

    With option "-quit", the process is slightly different:
      1. close *ALL* connections (irc, xfer, relay, ...)
      2. save session into files (*.upgrade)
      3. unload all plugins
      4. save WeeChat configuration
      5. quit WeeChat
    Then later you can restore session with command: weechat --upgrade
    IMPORTANT: you must restore the session with exactly same configuration (files *.conf).
    It is possible to restore WeeChat session on another machine if you copy the content of directory "~/.weechat".

- `uptime`: show WeeChat uptime

    /uptime  [-o | -ol]

     -o: send uptime to current buffer as input (English string)
    -ol: send uptime to current buffer as input (translated string)

- `version`: show WeeChat version and compilation date

    /version  [-o | -ol]

     -o: send version to current buffer as input (English string)
    -ol: send version to current buffer as input (translated string)

    The default alias /v can be used to execute this command on all buffers (otherwise the irc command /version is used on irc buffers).

- `wait`: schedule a command execution in future

    /wait  <number>[<unit>] <command>

     number: amount of time to wait (integer number)
       unit: optional, values are:
               ms: milliseconds
                s: seconds (default)
                m: minutes
                h: hours
    command: command to execute (or text to send to buffer if command does not start with '/')

    Note: the command is executed on buffer where /wait was executed (if the buffer does not exist any more, the command is not executed).

    Examples:
      join channel in 10 seconds:
        /wait 10 /join #test
      set away in 15 minutes:
        /wait 15m /away -all I'm away
      say 'hello' in 2 minutes:
        /wait 2m hello

- `window`: manage windows

    /window  list
             -1|+1|b#|up|down|left|right [-window <number>]
             <number>
             splith|splitv [-window <number>] [<pct>]
             resize [-window <number>] [h|v][+|-]<pct>

             merge [-window <number>] [all]
             close [-window <number>]
             page_up|page_down [-window <number>]
             refresh
             scroll [-window <number>] [+|-]<value>[s|m|h|d|M|y]
             scroll_horiz [-window <number>] [+|-]<value>[%]
             scroll_up|scroll_down|scroll_top|scroll_bottom|scroll_beyond_end|scroll_previous_highlight|scroll_next_highlight|scroll_unread [-window <number>]
             swap [-window <number>] [up|down|left|right]
             zoom [-window <number>]
             bare [<delay>]

             list: list opened windows (without argument, this list is displayed)
               -1: jump to previous window
               +1: jump to next window
               b#: jump to next window displaying buffer number #
               up: switch to window above current one
             down: switch to window below current one
             left: switch to window on the left
            right: switch to window on the right
           number: window number (see /window list)
           splith: split current window horizontally (to undo: /window merge)
           splitv: split current window vertically (to undo: /window merge)
           resize: resize window size, new size is <pct> percentage of parent window
                   if "h" or "v" is specified, the resize affects the nearest parent window with a split of this type (horizontal/vertical)
          balance: balance the sizes of all windows
            merge: merge window with another (all = keep only one window)
            close: close window
          page_up: scroll one page up
        page_down: scroll one page down
          refresh: refresh screen
           scroll: scroll a number of lines (+/-N) or with time: s=seconds, m=minutes, h=hours, d=days, M=months, y=years
     scroll_horiz: scroll horizontally a number of columns (+/-N) or percentage of window size (this scrolling is possible only on buffers with free content)
        scroll_up: scroll a few lines up
      scroll_down: scroll a few lines down
       scroll_top: scroll to top of buffer
    scroll_bottom: scroll to bottom of buffer
    scroll_beyond_end: scroll beyond the end of buffer
    scroll_previous_highlight: scroll to previous highlight
    scroll_next_highlight: scroll to next highlight
    scroll_unread: scroll to unread marker
             swap: swap buffers of two windows (with optional direction for target window)
             zoom: zoom on window
             bare: toggle bare display (with optional delay in seconds for automatic return to standard display mode)

    For splith and splitv, pct is a percentage which represents size of new window, computed with current window as size reference. For example 25 means create a new window with size = current_size / 4

    Examples:
      jump to window displaying buffer #1:
        /window b1
      scroll 2 lines up:
        /window scroll -2
      scroll 2 days up:
        /window scroll -2d
      scroll to beginning of current day:
        /window scroll -d
      zoom on window #2:
        /window zoom -window 2
      split window horizontally using 30% of space for the window on top:
        /window splith 30
      resize window to 75% of the parent window size:
        /window resize 75
      resize vertical split, add 10% in size:
        /window resize v+10
      remove the split, keep the current window:
        /window merge
      close the current window:
        /window close
      enable bare display for 2 seconds:
        /window bare 2

## 4. 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:

Plugin | Description
--- | ---
alias | Define alias for commands.
buflist | Bar item with list of buffers.
charset | Charset decoding/encoding for buffers.
exec | Execution of external commands in WeeChat.
fifo | FIFO pipe used to remotely send commands to WeeChat.
fset | Fast set of WeeChat and plugins options.
irc | IRC chat protocol.
logger | Log buffers to files.
relay | Relay data via network.
script | Script manager.
python | Python scripting API.
perl | Perl scripting API.
ruby | Ruby scripting API.
lua | Lua scripting API.
tcl | Tcl scripting API.
guile | Guile (scheme) scripting API.
javascript | JavaScript scripting API.
php | PHP scripting API.
spell | Spell checking for command line.
trigger | Text replacement and command execution on events triggered by WeeChat/plugins.
xfer | File transfer and direct chat.

To learn more about plugin or script development (through API), please read the WeeChat plugin API reference or the WeeChat scripting guide.

### 4.1. Alias

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

Some aliases are created by default, with name in upper case (to make them different from standard commands); commands are not case sensitive in WeeChat, so for example `/close` runs the alias `/CLOSE`.

List of default aliases:

Alias | Command | Completion
--- | --- | ---
`/AAWAY` | `/allserv /away` | -
`/ANICK` | `/allserv /nick` | -
`/BEEP` | `/print -beep` | -
`/BYE` | `/quit` | -
`/C` | `/buffer clear` | -
`/CL` | `/buffer clear` | -
`/CLOSE` | `/buffer close` | -
`/CHAT` | `/dcc chat` | -
`/EXIT` | `/quit` | -
`/IG` | `/ignore` | -
`/J` | `/join` | -
`/K` | `/kick` | -
`/KB` | `/kickban` | -
`/LEAVE` | `/part` | -
`/M` | `/msg` | -
`/MUB` | `/unban *` | -
`/MSGBUF` | `/command -buffer $1 * /input send $2-` | %(buffers_plugins_names)
`/N` | `/names` | -
`/Q` | `/query` | -
`/REDRAW` | `/window refresh` | -

### 4.2. Buflist

Buflist plugin displays a list of buffers in a bar item called "buflist" (two other bar items "buflist2" and "buflist3" are available as well).
A default bar "buflist" is created on startup with this item.

#### 4.2.1. Commands

- `buflist`: bar item with list of buffers

    /buflist  bar
              refresh

        bar: add the "buflist" bar
    refresh: force the refresh of the bar items (buflist, buflist2 and buflist3)

    The lines with buffers are displayed using string evaluation (see /help eval for the format), with these options:
      - buflist.look.display_conditions: conditions to display a buffer in the list
      - buflist.format.buffer: format for a buffer which is not current buffer
      - buflist.format.buffer_current: format for the current buffer

    The following variables can be used in these options:
      - bar item data (see hdata "bar_item" in API doc for a complete list), for example:
        - ${bar_item.name}
      - buffer data (see hdata "buffer" in API doc for a complete list), for example:
        - ${buffer.number}
        - ${buffer.name}
        - ${buffer.full_name}
        - ${buffer.short_name}
        - ${buffer.nicklist_nicks_count}
      - irc_server: IRC server data, defined only on an IRC buffer (see hdata "irc_server" in API doc)
      - irc_channel: IRC channel data, defined only on an IRC channel buffer (see hdata "irc_channel" in API doc)
      - extra variables added by buflist for convenience:
        - ${format_buffer}: the evaluated value of option buflist.format.buffer; this can be used in option buflist.format.buffer_current to just change the background color for example
        - ${current_buffer}: a boolean ("0" or "1"), "1" if this is the current buffer; it can be used in a condition: ${if:${current_buffer}?...:...}
        - ${merged}: a boolean ("0" or "1"), "1" if the buffer is merged with at least another buffer; it can be used in a condition: ${if:${merged}?...:...}
        - ${format_number}: indented number with separator (evaluation of option buflist.format.number)
        - ${number}: indented number, for example " 1" if there are between 10 and 99 buffers; for merged buffers, this variable is set with number for the first buffer and spaces for the next buffers with same number
        - ${number2}: indented number, for example " 1" if there are between 10 and 99 buffers
        - ${number_displayed}: "1" if the number is displayed, otherwise "0"
        - ${indent}: indentation for name (channel and private buffers are indented) (evaluation of option buflist.format.indent)
        - ${format_nick_prefix}: colored nick prefix for a channel (evaluation of option buflist.format.nick_prefix)
        - ${color_nick_prefix}: color of nick prefix for a channel (set only if the option buflist.look.nick_prefix is enabled)
        - ${nick_prefix}: nick prefix for a channel (set only if the option buflist.look.nick_prefix is enabled)
        - ${format_name}: formatted name (evaluation of option buflist.format.name)
        - ${name}: the short name (if set), with a fallback on the name
        - ${color_hotlist}: the color depending on the highest hotlist level for the buffer (evaluation of option buflist.format.hotlist_xxx where xxx is the level)
        - ${format_hotlist}: the formatted hotlist (evaluation of option buflist.format.hotlist)
        - ${hotlist}: the raw hotlist
        - ${hotlist_priority}: "none", "low", "message", "private" or "highlight"
        - ${format_lag}: the lag for an IRC server buffer, empty if there's no lag (evaluation of option buflist.format.lag)

### 4.3. Charset

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

#### 4.3.1. 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 set charset for all channels/privates of an IRC server:

    /set charset.encode.irc.freenode ISO-8859-15

To see all charsets used, use following command:

    /set charset.*

#### 4.3.2. Troubleshooting

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

#### 4.3.3. Commands

- `charset`: change charset for current buffer

    /charset  decode|encode <charset>
              reset

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

#### 4.3.4. Options

Sections in file charset.conf:

Section | Control command | Description
--- | --- | ---
`default` | `/set charset.default.*` | Default decoding/encoding charset.
`decode` | `/charset decode /set charset.decode.*` | Decoding charset by buffer (options can be added/removed in section).
`encode` | `/charset encode /set charset.encode.*` | Encoding charset by buffer (options can be added/removed in section).

Options:

- charset.default.decode

  - description: global decoding charset: charset used to decode incoming messages when they are not UTF-8 valid

  - type: string

  - values: any string

  - default value: `"iso-8859-1"`

- charset.default.encode

  - description: global encoding charset: charset used to encode outgoing messages (if empty, default is UTF-8 because it is the WeeChat internal charset)

  - type: string

  - values: any string

  - default value: `""`

### 4.4. Exec

### 4.5. Fifo

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

The FIFO pipe is located in ~/.weechat/ and is called weechat_fifo by default.

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

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

Some examples:

- Change nick on IRC server freenode to "newnick":

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

- Send a message on IRC #weechat channel:

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

- Send a message on current buffer:

    $ echo '*hello!' >~/.weechat/weechat_fifo

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

    $ printf '%b' '*/python unload\n*/python autoload\n' >~/.weechat/weechat_fifo

#### 4.5.1. Commands

- `fifo`: fifo plugin configuration

    /fifo  enable|disable|toggle

     enable: enable FIFO pipe
    disable: disable FIFO pipe
     toggle: toggle FIFO pipe

    FIFO pipe is used as remote control of WeeChat: you can send commands or text to the FIFO pipe from your shell.
    By default the FIFO pipe is in ~/.weechat/weechat_fifo

    The expected format is one of:
      plugin.buffer *text or command here
      *text or command here

    For example to change your freenode nick:
      echo 'irc.server.freenode */nick newnick' >~/.weechat/weechat_fifo

    Please read the user's guide for more info and examples.

    Examples:
      /fifo toggle

    Note: if input has one or more leading spaces, the following text is interpreted as a filter, without the spaces. For example " q" searches all options with "q" inside name while "q" closes the fset buffer.

    Examples:
      show IRC options changed:
        /fset d:irc.*
      show all options with "nicklist" in name:
        /fset nicklist
      show all values which contain "red":
        /fset =red
      show all values which are exactly "red":
        /fset ==red
      show all integer options in irc plugin:
        /fset c:${file} == irc && ${type_en} == integer

### 4.7. IRC

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).

#### 4.7.1. Command line options

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

    irc[6][s]://[nick[:password]@]irc.example.org[:port][/channel][,channel[...]]

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

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

#### 4.7.2. 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)

| 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

- Import certificate in shell:

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

| It is possible to concatenate many certificates in file CAs.pem.

- In WeeChat, with "oftc" server already added:

    /connect oftc

##### 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 added:

    /set irc.server.oftc.ssl_cert "%h/ssl/nick.pem"
    /connect oftc
    /msg nickserv cert add

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

#### 4.7.3. SASL authentication

WeeChat supports SASL authentication, using different mechanisms:

- plain: plain text password (default)

- ecdsa-nist256p-challenge: challenge with public/private key

- external: client side SSL cert

- dh-blowfish: blowfish encrypted password (insecure, not recommended)

- dh-aes: AES encrypted password (insecure, not recommended)

Options in servers are:

- sasl_mechanism: mechanism to use (see above)

- sasl_timeout: timeout (in seconds) for authentication

- sasl_fail: action to perform if authentication fails

- sasl_username: username (nick)

- sasl_password: password

- sasl_key: file with ECC private key (for mechanism ecdsa-nist256p-challenge)

##### SASL ECDSA-NIST256P-CHALLENGE

You must generate a private key in order to authentify with the ECDSA-NIST256P-CHALLENGE mechanism (no password is required on connection).

You can generate the key with this command:

    $ openssl ecparam -genkey -name prime256v1 -out ~/.weechat/ecdsa.pem

Get the public key (encoded as base64) with this command:

    $ openssl ec -noout -text -conv_form compressed -in ~/.weechat/ecdsa.pem | grep '^pub:' -A 3 | tail -n 3 | tr -d ' \n:' | xxd -r -p | base64

Connect to the server, identify (for example with "nickserv identify") and set your public key in your account, using nickserv (replace the base64 value with your public key):

    /connect freenode
    /msg nickserv identify your_password
    /msg nickserv set pubkey Av8k1FOGetUDq7sPMBfufSIZ5c2I/QYWgiwHtNXkVe/q

Configure the SASL options in the server:

    /set irc.server.freenode.sasl_mechanism ecdsa-nist256p-challenge
    /set irc.server.freenode.sasl_username "your_nickname"
    /set irc.server.freenode.sasl_key "%h/ecdsa.pem"

Reconnect to the server:

    /reconnect freenode

#### 4.7.4. 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.

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

    $ sudo apt-get install tor

In WeeChat you need to add 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, add a new server, for example:

    /server add freenode-tor ajnvpgl6prmkb7yktvue6im5wiedlz2w32uhcwaamdiecdrfpwwgnlqd.onion

| If you are using an old version of TOR (before 0.3.5) you should use the address `freenodeok2gncmy.onion` instead.

Set proxy for TOR:

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

Set SASL authentication with ECDSA-NIST256P-CHALLENGE (see the chapter SASL ECDSA-NIST256P-CHALLENGE to generate a private key):

    /set irc.server.freenode-tor.sasl_mechanism ecdsa-nist256p-challenge
    /set irc.server.freenode-tor.sasl_username "your_nickname"
    /set irc.server.freenode-tor.sasl_key "%h/ecdsa.pem"

And finally, connection to server:

    /connect freenode-tor

For more info about Freenode and TOR: https://freenode.net/kb/answer/chat#accessing-freenode-via-tor

#### 4.7.5. 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.

#### 4.7.6. 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:

Code | Description | Value/example
--- | --- | ---
     $clientinfo
| List of supported CTCP | `ACTION DCC CLIENTINFO FINGER PING SOURCE TIME USERINFO VERSION`
     $version
| WeeChat version | `0.4.0-dev`

#### 4.7.7. 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.

### 4.8. Logger

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

#### 4.8.1. 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

#### 4.8.2. 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").

##### 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

        │   │   └── irc.freenode.#weechat.weechatlog
        │   ├── 02
        ...

##### 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
            │   ├── #chan1.weechatlog
            │   └── #chan2.weechatlog
            ...

#### 4.8.3. Commands

- `logger`: logger plugin configuration

    /logger  list
             set <level>
             flush
             disable

       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)
      flush: write all log files now
    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.

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

    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"

### 4.9. Relay

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:

  - Glowing Bear (HTML5): https://www.glowing-bear.org/

  - QWeeChat (Qt): https://weechat.org/download

  - WeeChat-Android (Android): https://github.com/ubergeek42/weechat-android

  - weechat.el (Emacs): https://github.com/the-kenny/weechat.el

  - WeeCloud (JavaScript): https://github.com/eirikb/weecloud

#### 4.9.1. Password

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

    /set relay.network.password "mypassword"

This password is used for irc and weechat protocols.

#### 4.9.2. TOTP

TOTP (Time-based One-Time Password) can be used as secondary authentication factor for weechat protocol, in addition to the password.

This is optional and increases the security level.

One-time passwords can be generated with applications, for example:

- FreeOTP: Android, iOS (website)

- Google Authenticator: Android, iOS

The TOTP secret must be set in WeeChat and the application used to generate one-time passwords.

It must be a string encoded in base32, with only letters and digits from 2 to 7, for example:

    /set relay.network.totp_secret "secretpasswordbase32"

#### 4.9.3. 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 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

#### 4.9.4. 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 (see example below):

    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 "mypassword" (or "freenode:mypassword" if no server was specified in the relay).

For example if you use WeeChat as IRC client of the relay, with a server called "relay" and the relay password "secret", you can setup the password with this command:

    /set irc.server.relay.password "freenode:secret"

#### 4.9.5. WeeChat protocol

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

You can connect with a remote interface, see the list in Relay.

| WeeChat itself can NOT connect to another WeeChat with this protocol.

For example:

    /relay add weechat 9000

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

#### 4.9.6. WebSocket

WebSocket protocol (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 relay.network.websocket_allowed_origins).

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

    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).

#### 4.9.7. UNIX domain sockets

Using the protocol option "unix" with the `/relay add` command, you can listen using any protocol on a UNIX domain socket at a given path. For example:

    /relay add unix.weechat %h/relay_socket

This allows clients to connect using the weechat protocol to ~/.weechat/relay_socket. This is particularly useful to allow SSH forwarding for relay clients, when other ports cannot be opened. Using OpenSSH:

    $ ssh -L 9000:.weechat/relay_socket user@hostname

This redirects local relay clients connecting on port 9000 to the WeeChat instance running on "hostname".

#### 4.9.8. Commands

- `relay`: relay control

    /relay  list|listfull|listrelay
            add <name> <port>|<path>
            del|start|restart|stop <name>
            raw

              del: remove a relay (clients remain connected)
            start: listen on port
          restart: close the server socket and listen again on port (clients remain connected)
             stop: close the server socket (clients remain connected)
             name: relay name (see format below)
             port: port used for relay
             path: path used for relay (for UNIX domain socket only); "%h" at beginning of string is replaced by WeeChat home ("~/.weechat" by default), content is evaluated (see /help eval)
              raw: open buffer with raw Relay data
       sslcertkey: set SSL certificate/key using path in option relay.network.ssl_cert_key

    Relay name is: [ipv4.][ipv6.][ssl.]<protocol.name> or unix.[ssl.]<protocol.name>
             ipv4: force use of IPv4
             ipv6: force use of IPv6
              ssl: enable SSL
             unix: use UNIX domain socket
    protocol.name: protocol and name to relay:
                     - protocol "irc": name is the server to share (optional, if not given, the server name must be sent by client in command "PASS", with format: "PASS server:password")
                     - protocol "weechat" (name is not used)

    The "irc" protocol allows any IRC client (including WeeChat itself) to connect on the port.
    The "weechat" protocol allows a remote interface to connect on the port, see the list here: https://weechat.org/about/interfaces

    Without argument, this command opens buffer with list of relay clients.

    Examples:
      irc proxy, for server "freenode":
        /relay add irc.freenode 8000
      irc proxy, for server "freenode", with SSL:
        /relay add ssl.irc.freenode 8001

### 4.10. Scripts

WeeChat provides 8 scripting plugins: Python, Perl, Ruby, Lua, Tcl, Guile (scheme), JavaScript and PHP. These plugins can load, execute and unload scripts for these languages.

Another plugin called "script" is a script 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: https://weechat.org/scripts

For more information about how to write scripts, or WeeChat API for scripts, please read the WeeChat scripting guide.

### 4.11. Spell

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

Spell checking is disabled by default and can be toggled with key `Alt`+`s`.

#### 4.11.1. Dictionaries

Before using spell checking, dictionaries must be defined, either globally or specific to buffers.

Multiple dictionaries can be used at same time: WeeChat will check words in all dictionaries.

For example to use English and French:

    /set spell.check.default_dict "en,fr"

It is possible to use a different dictionary on a specific buffer, for example on a German channel:

    /spell setdict de

You can also specify a dictionary for a group of buffers, for example English for all channels on freenode IRC server:

    /set spell.dict.irc.freenode en

For more information, see the command /spell.

#### 4.11.2. Speller options

Speller options can be defined by adding options in section "option" of aspell configuration.

The option name is an aspell configuration option. List of options can be found in a shell with following command:

    $ aspell config

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

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

#### 4.11.3. Suggestions

Suggestions are displayed in a bar item called "spell_suggest". The number of suggestions is set in option spell.check.suggestions.

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

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

    │[12:55] [6] [irc/freenode] 3:#test(+n){4} [print,prone,prune]                    │
    │[@Flashy] prinr █                                                                │
    └─────────────────────────────────────────────────────────────────────────────────┘

Example of suggestions with English and French dictionaries (`en,fr`):

    │[12:55] [6] [irc/freenode] 3:#test(+n){4} [print,prone,prune/prime,primer,primé] │
    │[@Flashy] prinr █                                                                │
    └─────────────────────────────────────────────────────────────────────────────────┘

#### 4.11.4. Commands

- `spell`: spell plugin configuration

    /spell  enable|disable|toggle
            listdict
            setdict <dict>[,<dict>...]
            deldict
            addword [<dict>] <word>

      enable: enable spell checker
     disable: disable spell checker
      toggle: toggle spell checker
    listdict: show installed dictionaries
     setdict: set dictionary for current buffer (multiple dictionaries can be separated by a comma)
     deldict: delete dictionary used on current buffer
     addword: add a word in personal dictionary

    Input line beginning with a '/' is not checked, except for some commands (see /set spell.check.commands).

    To enable spell checker on all buffers, use option "default_dict", then enable spell checker, for example:
      /set spell.check.default_dict "en"
      /spell enable

    To display a list of suggestions in a bar, use item "spell_suggest".

    Default key to toggle spell checker is alt-s.

### 4.12. Trigger

Trigger is the Swiss Army knife for WeeChat: it can hook many things (signal, modifier, print, etc.), change the content of data, and execute one or more commands. A condition can be used to prevent the trigger to run in some circumstances.

Using triggers require you to know how the signals, modifiers, …​ are working. So you might consider reading the WeeChat plugin API reference / Hooks.

#### 4.12.1. Default triggers

WeeChat creates 5 triggers by default, which can be disabled, updated or deleted:

- a beep trigger for notifications

- four other triggers to hide passwords on screen

List of default triggers:

Name | Hook | Description
--- | --- | ---
`beep` | print | Beep on highlight/private message.
`cmd_pass` | modifier | Hide password in commands: `/msg nickserv id|identify|set password|ghost|release|regain|recover`, `/oper`, `/quote pass`, `/set *password*`, `/secure passphrase|decrypt|set`.
`cmd_pass_register` | modifier | Hide password in command `/msg nickserv register`.
`msg_auth` | modifier | Hide password in IRC auth message displayed (message received from server after the user issued the command).
`server_pass` | modifier | Hide server password in commands `/server` and `/connect`.

#### 4.12.2. Anatomy of a trigger

A trigger has the following options (names are `trigger.trigger.<name>.<option>`):

Option | Values | Description
--- | --- | ---
`enabled` | `on`, `off` | When option is `off`, the trigger is disabled and actions are not executed any more.
`hook` | `signal`, `hsignal`, `modifier`, `line`, `print`, `command`, `command_run`, `timer`, `config`, `focus`, `info`, `info_hashtable` | The hook used in trigger. For more information, see WeeChat plugin API reference / Hooks.
`arguments` | string | The arguments for the hook, it depends on the hook type used.
`conditions` | string | Conditions to execute the trigger; they are evaluated (see command /eval).
`regex` | string | One or more POSIX extended regular expressions, to change data received in the hook callback (and some stuff added by trigger plugin), see regular expression.
`command` | string | Command to execute (many commands can be separated by semicolons); it is evaluated (see command /eval).
`return_code` | `ok`, `ok_eat`, `error` | The return code of callback (default is `ok`, which should be used in almost all triggers, the other values are rarely used).
`post_action` | `none`, `disable`, `delete` | Action to take on the trigger after execution (default is `none` which should be used in almost all triggers, the other values are rarely used).

For example, the default beep trigger has following options:

    trigger.trigger.beep.enabled = on
    trigger.trigger.beep.hook = print
    trigger.trigger.beep.arguments = ""
    trigger.trigger.beep.conditions = "${tg_displayed} && (${tg_highlight} || ${tg_msg_pv})"
    trigger.trigger.beep.regex = ""
    trigger.trigger.beep.command = "/print -beep"
    trigger.trigger.beep.return_code = ok
    trigger.trigger.beep.post_action = none

#### 4.12.3. Execution

When a trigger callback is called, following actions are executed, in this order, if triggers are globally enabled and if the trigger itself is enabled:

1. check trigger conditions: if false, exit

2. replace text in trigger using regular expression(s)

3. execute command(s)

4. exit with a return code (except for hooks modifier, line, focus, info and info_hashtable)

5. perform post action (if different from `none`).

#### 4.12.4. Hook arguments

The arguments depend on the hook used. They are separated by semicolons.

Hook | Arguments | Examples | Documentation (API)
--- | --- | --- | ---
signal | 1. signal name (priority allowed) (required) 2. signal name (priority allowed) 3. …​ | `*,irc_in_privmsg` `*,irc_in_privmsg;*,irc_in_notice` `signal_sigwinch` | hook_signal
hsignal | 1. signal name (priority allowed) (required) 2. signal name (priority allowed) 3. …​ | `nicklist_nick_added` | hook_hsignal
modifier | 1. modifier name (priority allowed) (required) 2. modifier name (priority allowed) 3. …​ | `weechat_print` `5000|input_text_display;5000|history_add` | hook_modifier
line | 1. buffer type 2. buffer name 3. tags | `formatted` `free` `*;irc.freenode.*` `*;irc.freenode.#weechat` `formatted;irc.freenode.#weechat;irc_notice` | hook_line
print | 1. buffer name 2. tags 3. message 4. strip colors (0/1) | `irc.freenode.*` `irc.freenode.#weechat` `irc.freenode.#weechat;irc_notice` `*;;;1` | hook_print
command | 1. command name (priority allowed) (required) 2. description 3. arguments 4. description of arguments 5. completion | `test` `5000|test` | hook_command
command_run | 1. command (priority allowed) (required) 2. command (priority allowed) 3. …​ | `/cmd arguments` | hook_command_run
timer | 1. interval in milliseconds (required) 2. alignment on second (default: 0) 3. max number of calls (default: 0, which means "no end") | `3600000` `60000;0;5` | hook_timer
config | 1. option name (priority allowed) (required) 2. option name (priority allowed) 3. …​ | `weechat.look.*` | hook_config
focus | 1. area name (priority allowed) (required) 2. area name (priority allowed) 3. …​ | `buffer_nicklist` | hook_focus
info | 1. info name (priority allowed) (required) 2. info name (priority allowed) 3. …​ | `my_info` | hook_info
info_hashtable | 1. info name (priority allowed) (required) 2. info name (priority allowed) 3. …​ | `my_info` | hook_info_hashtable

#### 4.12.5. Conditions

The conditions are used to continue processing in trigger, or stop everything.

They are evaluated, and data available in callback can be used (see data in callbacks and command /eval).

Example: the default beep trigger uses this condition to make a beep only on highlight or private message:

    ${tg_displayed} && (${tg_highlight} || ${tg_msg_pv})

#### 4.12.6. Regular expression

The regular expression is used to change variables in callback hashtable.

The format is: "/regex/replace" or "/regex/replace/var" (where var is a variable of the hashtable).

If var does not exist in the hashtable, it is created automatically with an empty value. This allows to create custom temporary variables.

If var is not specified, the default variable is used, it depends on hook type:

Hook | Default variable | Update allowed (1)
--- | --- | ---
signal | tg_signal_data |
hsignal |  |
modifier | tg_string | tg_string
line | message | buffer, buffer_name, y, date, date_printed, str_time, tags, notify_level, highlight, prefix, message
print | tg_message |
command | tg_argv_eol1 |
command_run | tg_command |
timer | tg_remaining_calls |
config | tg_value |
focus |  |
info | tg_info | tg_info
info_hashtable |  | all variables received in hashtable

| (1) All variables can be updated in the trigger, but only these variables have an effect on the value returned by the trigger and used by WeeChat.

Many regular expressions can be separated by a space, for example: "/regex1/replace1/var1 /regex2/replace2/var2".

The char "/" can be replaced by any char (one or more identical chars).

Matching groups can be used in "replace":

- `${re:0}` to `${re:99}`: `${re:0}` is the whole match, `${re:1}` to `${re:99}` are groups captured

- `${re:+}`: the last match (with highest number)

- `${hide:c,${re:N}}`: match "N" with all chars replaced by "c" (example: `${hide:*,${re:2}}` is the group #2 with all chars replaced by `*`).

Example: use bold for words between `*`:

    /\*([^ ]+)\*/*${color:bold}${re:1}${color:-bold}*/

Example: default trigger server_pass uses this regular expression to hide password in commands `/server` and `/connect` (chars in passwords are replaced by `*`):

    ==^(/(server|connect) .*-(sasl_)?password=)([^ ]+)(.*)==${re:1}${hide:*,${re:4}}${re:5}

| In this example, the delimiter used is "==" because there is a "/" in the regular expression.

#### 4.12.7. Command

The command is executed after replacement of text with the regular expression. Many commands can be separated by semicolons.

It is evaluated (see command /eval) and text replaced with a regular expression can be used in the command.

Example: default beep trigger uses this command to make a beep (BEL):

    /print -beep

#### 4.12.8. Data in callbacks

Data received in callbacks are stored in hashtables (pointers and strings) and can be used in following options:

- conditions

- regex

- command

The content of hashtables depend on the hook type.

A convenient way to see data in a trigger is to open trigger monitor buffer, using the command:

    /trigger monitor

##### Signal

--- | --- | ---
`irc_server` | pointer | Pointer to IRC server (variables in hdata of type "irc_server" can be used, like `${irc_server.name}`).
`irc_channel` | pointer | Pointer to IRC channel (variables in hdata of type "irc_channel" can be used, like `${irc_channel.name}`).
`server` | string | Name of server (example: "freenode").

`pos_channel` | string | The index of channel in message ("-1" if channel was not found).
`pos_text` | string | The index of text in message ("-1" if text was not found).

When the data is a pointer, the variable `tg_signal_data` can be used like this to read a hdata property (in this example this is a pointer on a buffer):

    ${buffer[${tg_signal_data}].full_name}

##### Hsignal

Display URLs in green:

    /trigger add url_color modifier weechat_print "${tg_notify}" "==[a-zA-Z0-9_]+://[^ ]+==${color:green}${re:0}${color:reset}=="

| The simple regex used to detect URL may not catch well all URLs, but it is faster than a complex regex.

##### Auto pong on ping queries

When someone sends a "ping" in a private buffer, this trigger will auto-reply with `pong`:

    /trigger add pong print "" "${type} == private && ${tg_message} == ping" "" "pong"

##### Responsive layout

Following triggers can be used to customize things displayed when the size of terminal is changed:

    /trigger add resize_small signal signal_sigwinch "${info:term_width} < 100" "" "/bar hide nicklist"
    /trigger add resize_big signal signal_sigwinch "${info:term_width} >= 100" "" "/bar show nicklist"

The triggers catch the signal "signal_sigwinch", which is sent by WeeChat when signal SIGWINCH is received (when terminal size is changed).

The condition with `${info:term_width}` checks the width of terminal (you can also use `${info:term_height}` if needed).

In the example, when the terminal becomes small, the nicklist is hidden. And the bar is restored when the width is greater or equal to 100 chars.

##### Automatic save of configuration

You can automatically save configuration files (`*.conf`), for example each hour:

    /trigger add cfgsave timer 3600000;0;0 "" "" "/mute /save"

Arguments for the timer hook are:

- 3600000: 3600 * 1000 milliseconds, the callback is called each hour

- 0: alignment on second (not aligned here)

- 0: max number of calls (0 = no end for the timer)

The command `/mute /save` will silently save configuration files (nothing displayed on core buffer).

    When a trigger callback is called, following actions are performed, in this order:
      1. check conditions; if false, exit
      2. replace text using POSIX extended regular expression(s) (if defined in trigger)
      3. execute command(s) (if defined in trigger)
      4. exit with a return code (except for modifier, line, focus, info and info_hashtable)
      5. perform post action

    Examples (you can also look at default triggers with /trigger listdefault):
      add text attributes *bold*, _underline_ and /italic/ (only in user messages):
        /trigger add effects modifier weechat_print "${tg_tag_nick}" "==\*([^ ]+)\*==*${color:bold}${re:1}${color:-bold}*== ==_([^ ]+)_==_${color:underline}${re:1}${color:-underline}_== ==/([^ ]+)/==/${color:italic}${re:1}${color:-italic}/"

        /trigger add resize_small signal signal_sigwinch "${info:term_width} < 100" "" "/bar hide nicklist"
        /trigger add resize_big signal signal_sigwinch "${info:term_width} >= 100" "" "/bar show nicklist"
      silently save config each hour:
        /trigger add cfgsave timer 3600000;0;0 "" "" "/mute /save"
      open trigger monitor and show only modifiers and triggers whose name starts with "resize":
        /trigger monitor @modifier,resize*
