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

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

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

Colors
^^^^^^

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

^Cb::
    bold text

^Ccxx::
    text color `xx` (see list of colors below)

^Ccxx,yy::
    text color `xx` and background `yy` (see list of colors below)

^Co::
    disable color and attributes

^Cr::
    reverse video (revert text color with background)

^Cu::
    underlined text

[NOTE]
The same code (without number for ^Cc) may be used to stop the
attribute.

Color codes for ^Cc are:

[width="20%",cols="^1m,2"]
|========================================
| 00 | white
| 01 | black
| 02 | dark blue
| 03 | dark green
| 04 | light red
| 05 | dark red
| 06 | magenta
| 07 | orange

| 09 | light green
| 10 | cyan
| 11 | light cyan
| 12 | light blue
| 13 | light magenta
| 14 | gray
| 15 | light gray (white)
|========================================

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

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

Plugins
-------

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

[[plugins_in_weechat]]
Plugins in WeeChat
~~~~~~~~~~~~~~~~~~

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

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

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

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

Examples to load, unload or list plugins:

----------------------------------------
/plugin load irc
/plugin unload irc
/plugin list
----------------------------------------

Default plugins are:

[width="50%",cols=">1s,5",options="header"]
|========================================
| Plugin  | Description
| alias   | Define alias for commands
| aspell  | Spell checking for command line
| charset | Charset decoding/encoding for buffers
| demo    | Demo plugin (not compiled by default)
| fifo    | FIFO pipe used to remotely send commands to WeeChat
| irc     | IRC chat protocol
| logger  | Log buffers to files
| perl    | Perl scripting API
| python  | Python scripting API
| ruby    | Ruby scripting API
| lua     | Lua scripting API
| tcl     | Tcl scripting API
| xfer    | File transfer and direct chat
|========================================

[[alias_plugin]]
Alias plugin
~~~~~~~~~~~~

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

Commands
^^^^^^^^

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

[[aspell_plugin]]
Aspell plugin
~~~~~~~~~~~~

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

Options (aspell.conf)
^^^^^^^^^^^^^^^^^^^^^

[[charset_plugin]]
Charset plugin
~~~~~~~~~~~~~~

Charset plugin lets you decode or encode data using charsets.

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

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

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

----------------------------------------
/charset
----------------------------------------

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

----------------------------------------
/plugin load charset
----------------------------------------

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

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

For example:

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

Options (charset.conf)
^^^^^^^^^^^^^^^^^^^^^^

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

Commands
^^^^^^^^

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

Set charset
^^^^^^^^^^^

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

For example:

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

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

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

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

For example:

----------------------------------------
/charset ISO-8859-15
----------------------------------------

It's equivalent to:

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

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

To see all charsets used, use following command:

----------------------------------------
/set charset.*
----------------------------------------

Troubleshooting
^^^^^^^^^^^^^^^

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

[[fifo_plugin]]
Fifo plugin
~~~~~~~~~~~

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

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

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

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

Some examples:

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

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

* display text on IRC #weechat channel:

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

* display text on current buffer:

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

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

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

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

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

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

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

[[irc_plugin]]
IRC plugin
~~~~~~~~~~

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

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

Command line options
^^^^^^^^^^^^^^^^^^^^

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

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

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

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

Options (irc.conf)
^^^^^^^^^^^^^^^^^^

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

Commands
^^^^^^^^

[[ctcp_replies]]
CTCP replies
^^^^^^^^^^^^

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

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

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

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

----------------------------------------
/set irc.ctcp.version ""
----------------------------------------

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

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

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

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

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

----------------------------------------
/unset irc.ctcp.version
----------------------------------------

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

[width="100%",cols="^2,4,8",options="header"]
|========================================
| Code           | Description                 | Value/example
| `$clientinfo`  | list of supported CTCP      | `ACTION DCC CLIENTINFO FINGER PING SOURCE TIME USERINFO VERSION`

| `$username`    | username on IRC server      | `nick`
| `$realname`    | realname on IRC server      | `My name`
|========================================

If CTCP options are not defined (by default), CTCP replies are:

[[logger_plugin]]
Logger plugin
~~~~~~~~~~~~~

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

Options (logger.conf)
^^^^^^^^^^^^^^^^^^^^^

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

Commands
^^^^^^^^

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

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

Filenames masks
^^^^^^^^^^^^^^^

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

----------------------------------------
/buffer localvar
----------------------------------------

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

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

You'll have following files:

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