= WeeChat Plugin API Reference
Sébastien Helleu <flashcode@flashtux.org>
This manual documents WeeChat chat client, it is part of WeeChat.
Latest version of this document can be found on this page:
http://weechat.org/doc
[[introduction]]
== Introduction
WeeChat (Wee Enhanced Environment for Chat) is a free chat client, fast and
light, designed for many operating systems.
This manual documents WeeChat plugins API, used by C plugins to interact with
WeeChat core.
[[plugins_in_weechat]]
== Plugins in WeeChat
A plugin is a C program which can call WeeChat functions defined in an
interface.
This C program does not need WeeChat sources to compile and can be dynamically
loaded into WeeChat with command `/plugin`.
The plugin has to be a dynamic library, for dynamic loading by operating
system.
Under GNU/Linux, the file has ".so" extension, ".dll" under Windows.
The plugin has to include "weechat-plugin.h" file (available in WeeChat source
code).
This file defines structures and types used to communicate with WeeChat.
[[macros]]
=== Macros
The plugin must use some macros (to define some variables):
WEECHAT_PLUGIN_NAME("name")::
plugin name
WEECHAT_PLUGIN_DESCRIPTION("description")::
short description of plugin
WEECHAT_PLUGIN_VERSION("1.0")::
plugin version
WEECHAT_PLUGIN_LICENSE("GPL3")::
plugin license
[[main_functions]]
=== Main functions
The plugin must use two functions:
* weechat_plugin_init
* weechat_plugin_end
==== weechat_plugin_init
This function is called when plugin is loaded by WeeChat.
Prototype:
[source,C]
----
int weechat_plugin_init (struct t_weechat_plugin *plugin,
int argc, char *argv[]);
----
Arguments:
* 'plugin': pointer to WeeChat plugin structure
* 'argc': number of arguments for plugin (given on command line by user)
* 'argv': arguments for plugin
Return value:
* 'WEECHAT_RC_OK' if successful (plugin will be loaded)
* 'WEECHAT_RC_ERROR' if error (plugin will NOT be loaded)
==== weechat_plugin_end
This function is called when plugin is unloaded by WeeChat.
Prototype:
[source,C]
----
int weechat_plugin_end (struct t_weechat_plugin *plugin);
----
Arguments:
* 'plugin': pointer to WeeChat plugin structure
Return value:
* 'WEECHAT_RC_OK' if successful
* 'WEECHAT_RC_ERROR' if error
[[compile_plugin]]
=== Compile plugin
Compile does not need WeeChat sources, only file 'weechat-plugin.h' is
required.
To compile a plugin which has one file "toto.c" (under GNU/Linux):
----
$ gcc -fPIC -Wall -c toto.c
$ gcc -shared -fPIC -o libtoto.so toto.o
----
[[load_plugin]]
=== Load plugin
Copy file 'libtoto.so' into system plugins directory (for example
'/usr/local/lib/weechat/plugins') or into user's plugins directory (for example
'/home/xxx/.weechat/plugins').
Under WeeChat:
----
/plugin load toto
----
[[plugin_example]]
=== Plugin example
Full example of plugin, which adds a command '/double': displays two times
arguments on current buffer, or execute two times a command (ok that's not
very useful, but that's just an example!):
[source,C]
----
#include <stdlib.h>
#include "weechat-plugin.h"
WEECHAT_PLUGIN_NAME("double");
WEECHAT_PLUGIN_DESCRIPTION("Test plugin for WeeChat");
WEECHAT_PLUGIN_AUTHOR("Sébastien Helleu <flashcode@flashtux.org>");
WEECHAT_PLUGIN_VERSION("0.1");
WEECHAT_PLUGIN_LICENSE("GPL3");
struct t_weechat_plugin *weechat_plugin = NULL;
/* callback for command "/double" */
int
command_double_cb (void *data, struct t_gui_buffer *buffer, int argc,
char **argv, char **argv_eol)
{
/* make C compiler happy */
(void) data;
(void) buffer;
(void) argv;
if (argc > 1)
{
weechat_command (NULL, argv_eol[1]);
weechat_command (NULL, argv_eol[1]);
}
return WEECHAT_RC_OK;
}
int
weechat_plugin_init (struct t_weechat_plugin *plugin,
int argc, char *argv[])
{
weechat_plugin = plugin;
weechat_hook_command ("double",
"Display two times a message "
"or execute two times a command",
"message | command",
"message: message to display two times\n"
"command: command to execute two times",
NULL,
&command_double_cb, NULL);
return WEECHAT_RC_OK;
}
int
weechat_plugin_end (struct t_weechat_plugin *plugin)
{
/* make C compiler happy */
(void) plugin;
return WEECHAT_RC_OK;
}
----
[[plugin_api]]
== Plugin API
Following chapters describe functions in API, sorted by category.
For each function, we give:
* description of function,
* C prototype,
* detail of arguments,
* return value,
* C example,
* example in Python script (syntax for other scripting languages is similar).
[[plugins]]

message will have no alignment at all. Moreover, the date in message will be
set to 0.

[[hooks]]
=== Hooks
[[hook_priority]]
[float]
==== Hook priority
_WeeChat ≥ 0.3.4._
In some hooks, you can set a priority. A hook with higher priority is at the
beginning of hooks list, so it will be found and executed before other hooks.
It's useful for modifiers, because execution order is important.
To set a priority, you must use this syntax, for argument where priority is
allowed: "nnn|name" where "nnn" is nonnegative integer with priority and "name"
the name for argument (priority does not appear in name, it is automatically
removed from string).
Default priority is 1000.
C example:
[source,C]
----
/* hook modifier with priority = 2000 */
weechat_hook_modifier ("2000|input_text_display", &modifier_cb, NULL);
----
Following hook types allow priority: command, command_run, signal, hsignal,
config, completion, modifier, info, info_hashtable, infolist, hdata, focus.
==== weechat_hook_command
Hook a command.
Prototype:
[source,C]
----
struct t_hook *weechat_hook_command (const char *command,
const char *description,
const char *args,
const char *args_description,
const char *completion,
int (*callback)(void *data,
struct t_gui_buffer *buffer,
int argc,
char **argv,
char **argv_eol),
void *callback_data);
----
Arguments:
* 'command': command name
(priority allowed, see note about <<hook_priority,priority>>)
* 'description': description for command (displayed with `/help command`)
* 'args': arguments for command (displayed with `/help command`)
* 'args_description': description of arguments (displayed with `/help command`)
* 'completion': completion template for command: list of completions for each
argument, separated by space. Many completions are possible for one
argument, separated by "|". Many templates are possible for same command,
separated by "||".
* 'callback': function called when command is used, arguments and return value:
** 'void *data': pointer
** 'struct t_gui_buffer *buffer': buffer where command is executed
** 'int argc': number of arguments given for command
** 'char **argv': arguments given for command
** 'char **argv_eol': arguments given for command (until end of line for each
argument)
** return value:
*** 'WEECHAT_RC_OK'
*** 'WEECHAT_RC_ERROR'
* 'callback_data': pointer given to callback when it is called by WeeChat
Default completion codes are:
include::autogen/plugin_api/completions.txt[]
Special codes:
* '%%command': reuse completion template from command 'command'
* '%-': stop completion
* '%*': repeat last completion
Return value:
* pointer to new hook, NULL if error occurred
C example:
[source,C]
----
int
my_command_cb (void *data, struct t_gui_buffer *buffer, int argc,
char **argv, char **argv_eol)
{
/* ... */
return WEECHAT_RC_OK;
}
/* this example is inspired by command /filter */
struct t_hook *my_command_hook =
weechat_hook_command (/* command name */
"myfilter",
/* description */
"description of myfilter",
/* args */
"[list] | [enable|disable|toggle [name]] | "
"[add name plugin.buffer tags regex] | "
"[del name|-all]",
/* args description */
"description of arguments...",
/* completion */
"list"
" || enable %(filters_names)"

" || toggle %(filters_names)"
" || add %(filters_names) %(buffers_plugins_names)|*"
" || del %(filters_names)|-all",
/* callback */
&my_command_cb,
/* callback_data */
NULL);
----
For example, if command called is `/command abc def ghi`, then 'argv' and
'argv_eol' have following values:
* 'argv':
** 'argv[0]' == "/command"
** 'argv[1]' == "abc"
** 'argv[2]' == "def"
** 'argv[3]' == "ghi"
* 'argv_eol':
** 'argv_eol[0]' == "/command abc def ghi"
** 'argv_eol[1]' == "abc def ghi"
** 'argv_eol[2]' == "def ghi"
** 'argv_eol[3]' == "ghi"
For scripts, 'args' has value "abc def ghi".

----
==== weechat_hook_process
Hook a process (launched with fork), and catch output.
[NOTE]
Since version 0.3.9.2, the shell is not used any more to execute the command.
WeeChat makes an automatic split of the command and its arguments (like the
shell does). +
If the split is not correct (according to quotes in your command), or if you
want to use shell, you can use function
<<_weechat_hook_process_hashtable,weechat_hook_process_hashtable>> with
arguments in the hashtable 'options' _(WeeChat ≥ 0.4.0)_.
Prototype:
[source,C]
----
struct t_hook *weechat_hook_process (const char *command,
int timeout,
int (*callback)(void *data,
const char *command,
int return_code,
const char *out,
const char *err),
void *callback_data);
----
Arguments:
* 'command': command to launch in child process or URL _(WeeChat ≥ 0.3.7)_,
see below
* 'timeout': timeout for command (in milliseconds): after this timeout, child
process is killed (0 means no timeout)
* 'callback': function called when data from child is available, or when child
has ended, arguments and return value:
** 'void *data': pointer
** 'const char *command': command executed by child
** 'int return_code': return code:
*** '>= 0': child return code for a command, and for URL possible values are:
**** '0': transfer ok
**** '1': invalid URL
**** '2': transfer error
**** '3': not enough memory
**** '4': error with a file
*** '< 0': 'WEECHAT_HOOK_PROCESS_RUNNING' (data available, but child still
running) or 'WEECHAT_HOOK_PROCESS_ERROR' (error when launching command)
** 'out': standard output of command (stdout)
** 'err': error output of command (stderr)
** return value:
*** 'WEECHAT_RC_OK'
*** 'WEECHAT_RC_ERROR'
* 'callback_data': pointer given to callback when it is called by WeeChat
Return value:
* pointer to new hook, NULL if error occurred
When command has ended, or if timeout is reached, WeeChat will automatically
unhook (and kill process if it is still running).
The command can be an URL with format: "url:http://www.example.com", to download
content of URL _(WeeChat ≥ 0.3.7)_. Options are possible for URL with
function <<_weechat_hook_process_hashtable,weechat_hook_process_hashtable>>.
[TIP]
If you want to retrieve infos about WeeChat (like current stable version,
latest git commit, ...), you can use URLs on page http://weechat.org/dev/info
[NOTE]
Buffer size for sending data to callback is 64KB (there are 2 buffers: one for
stdout and one for stderr).
If output from child process (stdout or stderr) is longer than 64KB, callback
will be called more than one time.
[IMPORTANT]
Even if most of times your callback is called only once, you must ensure that
many calls to callback are ok in your code: you must concatenate data issued by
many calls and use data only when return code is nonnegative.
C example:
[source,C]
----

----
Arguments are the same as function <<_weechat_hook_process,weechat_hook_process>>,
with an extra argument:
* 'options': options for command executed; the hashtable is duplicated in
function, so it's safe to free it after this call
For a standard command (not beginning with "url:"), the hashtable 'options' can
contain arguments for command (and then 'command' must be only the command
without arguments) _(WeeChat ≥ 0.4.0)_. +
The keys in hashtable must be: 'arg1', 'arg2', ...
For command "url:...", following options are available (see
`man curl_easy_setopt` for a description of each option):
include::autogen/plugin_api/url_options.txt[]
[NOTE]
^(1)^ When constants are available they must be used as value for option. For
options with type "mask", format is: "value1+value2+value3".
For URL, two extra options (strings) are allowed for input/output file:
* 'file_in': file to read and send with URLs (post file)
* 'file_out': write downloaded URL/file in this file (instead of standard
output)
Return value:
* pointer to new hook, NULL if error occurred

commands will be sent to callbacks, other will be ignored) (optional)
Immediately after sending this hsignal, you must send command to irc server,
and redirection will be used for this command.
When complete answer to your command has been be received, a hsignal will be
send. This hsignal has name 'irc_redirection_xxx_yyy' where 'xxx' is the
'signal' and 'yyy' the 'pattern' used.
Hashtable sent in hsignal has following content (key and values are strings):
* 'output': output of command (messages are separated by "\n")

[[hsignal_irc_redirect_pattern]]
===== Hsignal irc_redirect_pattern
_WeeChat ≥ 0.3.4._
The hsignal "irc_redirect_pattern" can be sent to create a pattern for irc
redirect (see <<hsignal_irc_redirect_command>>).
Argument is a hashtable with following entries (keys and values are string):
* 'pattern': name of pattern (required)
* 'timeout': default timeout for pattern, in seconds (optional, 60 by default)
* 'cmd_start': comma-separated list of commands starting redirect (optional)
* 'cmd_stop': comma-separated list of commands stopping redirect (required)

<<_weechat_hook_command_run,weechat_hook_command_run>> with command:
"/input complete_next" (and you must return 'WEECHAT_RC_OK_EAT' if your callback
has updated the command line, so that WeeChat will not perform the completion).

[IMPORTANT]
For a mouse gesture, your callback will be called two times: first time when
button is pressed (here the area always matches your area), second time when
button is released, and then the area may not match your area: so you must
*always* test in your callback if area is matching before using info in
hashtable.

=== Infolists
An infolist is a list of "items". Each item contains variables.
For example, infolist "irc_server" has N items (N is number of IRC servers
defined). For each item, there is variables like "name", "buffer",
"is_connected", ...
Each variable has a type and a value. Possible types are:
* 'integer': any integer value
* 'string': any string value
* 'pointer': any pointer
* 'buffer': buffer with fixed length, containing any data
* 'time': time value
