= WeeChat plugin API reference :author: Sébastien Helleu :email: flashcode@flashtux.org :lang: en :toc: :toclevels: 4 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 #include "weechat-plugin.h" WEECHAT_PLUGIN_NAME("double"); WEECHAT_PLUGIN_DESCRIPTION("Test plugin for WeeChat"); WEECHAT_PLUGIN_AUTHOR("Sébastien Helleu "); 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]] === Plugins Functions to get infos about plugins. ==== weechat_plugin_get_name Get plugin name.

[[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 non-negative 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.

[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)_.

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 non-negative.
