# HexChat Plugin Interface
|
|
|
|
## Introduction
|
|
Plugins for HexChat are written in C. The interface aims to keep 100%
|
|
binary compatability. This means that if you upgrade HexChat, you will
|
|
not need to recompile your plugins, they'll continue to work. The
|
|
interface doesn't depend on any structures and offsets, so compiler
|
|
versions shouldn't have an impact either. The only real requirement of
|
|
a HexChat plugin is that it define an _hexchat\_plugin\_init_ symbol. This
|
|
is your entry point function, see the example below. You should make
|
|
all your global variables and functions _static_, so that a symbol
|
|
is not exported. There is no harm in exporting these symbols, but they
|
|
are not necessary and only pollute the name-space. Plugins are compiled as shared objects
|
|
(.so files), for example:
|
|
|
|
Most UNIX systems:
|
|
> gcc -Wl,--export-dynamic -Wall -O1 -shared -fPIC myplugin.c -o myplugin.so
|
|
|
|
OS X:
|
|
> gcc -no-cpp-precomp -g -O2 -Wall -bundle -flat_namespace -undefined suppress -o myplugin.so myplugin.c
|
|
|
|
See the Windows section on how to compile a plugin using Visual Studio.
|
|
|
|
All strings passed to and from plugins are encoded in UTF-8, regardless
|
|
of locale.
|
|
|
|
## Sample plugin
|
|
|
|
This simple plugin auto-ops anyone who joins a channel you're in. It also
|
|
adds a new command _/AUTOOPTOGGLE_, which can be used to turn the feature ON
|
|
or OFF. Every HexChat plugin must define an _hexchat\_plugin\_init_ function, this
|
|
is the normal entry point. _hexchat\_plugin\_deinit_ is optional.
|
|
|
|
<pre>
|
|
#include "hexchat-plugin.h"
|
|
|
|
#define PNAME "AutoOp"
|
|
#define PDESC "Auto Ops anyone that joins"
|
|
#define PVERSION "0.1"
|
|
|
|

|
|
|
|

|
|

|
|
{
|
|
if (enable)
|
|
{
|
|
/* Op ANYONE who joins */
|
|
hexchat_commandf (ph, "OP %s", word[1]);
|
|
}
|
|
/* word[1] is the nickname, as in the Settings->Text Events window in HexChat */
|
|
|
|
return HEXCHAT_EAT_NONE; /* don't eat this event, HexChat needs to see it! */
|
|
}
|
|
|
|
static int
|
|
autooptoggle_cb (char *word[], char *word_eol[], void *userdata)
|
|
{
|
|
if (!enable)
|
|
{
|
|

|
|

|
|
}
|

|
|
hexchat_plugin_get_info (char **name, char **desc, char **version, void **reserved)
|
|
{
|
|
*name = PNAME;
|
|
*desc = PDESC;
|
|
*version = PVERSION;
|
|
}
|
|
|
|
int
|
|
hexchat_plugin_init (hexchat_plugin *plugin_handle, char **plugin_name, char **plugin_desc, char **plugin_version, char *arg)

|
|

|
|

|
|

|
|

|
|
|
|
hexchat_hook_command (ph, "AutoOpToggle", HEXCHAT_PRI_NORM, autooptoggle_cb, "Usage: AUTOOPTOGGLE, Turns OFF/ON Auto Oping", 0);
|
|
hexchat_hook_print (ph, "Join", HEXCHAT_PRI_NORM, join_cb, 0);
|
|
|
|
hexchat_print (ph, "AutoOpPlugin loaded successfully!\n");
|
|
|
|
return 1; /* return 1 for success */
|
|
}
|
|
</pre>
|
|
|
|
|
|
## What's _word_ and _word\_eol_?
|
|
|
|
They are arrays of strings. They contain the parameters the user entered
|
|
for the particular command. For example, if you executed:
|
|
|
|
<pre>
|
|
/command NICK hi there
|
|
|
|
word[1] is command
|
|
word[2] is NICK
|
|
word[3] is hi
|
|
word[4] is there
|
|
|
|
word_eol[1] is command NICK hi there
|
|
word_eol[2] is NICK hi there
|
|
word_eol[3] is hi there
|
|
word_eol[4] is there
|
|
</pre>
|
|
|
|
These arrays are simply provided for your convenience. You are **not** allowed
|
|
to alter them. Both arrays are limited to 32 elements (index 31). _word[0]_ and
|
|
_word\_eol[0]_ are reserved and should not be read.
|
|
|
|
## Lists and Fields
|
|
Lists of information (DCCs, Channels, User list, etc.) can be retreived
|
|
with _hexchat\_list\_get_. All fields are **read only** and must be copied if
|
|
needed for a long time after calling _hexchat\_list\_str_. The types of lists and fields available are:
|
|
|
|

## Plugins on Windows (Win32)
|
|
|
|
All you need is Visual Studio setup as explained in [Building](http://www.hexchat.org/developers/building). Your best bet is to use an existing plugin (such as the currently unused SASL plugin) in the HexChat solution as a starting point. You should have the following files:
|
|
|
|
|
|
* [hexchat-plugin.h](https://github.com/hexchat/hexchat/blob/master/src/common/hexchat-plugin.h) - main plugin header
|
|
* plugin.c - Your plugin, you need to write this one :)
|
|
* plugin.def - A simple text file containing the following:
|
|
|
|
<pre>
|
|
EXPORTS
|
|
hexchat_plugin_init
|
|
hexchat_plugin_deinit
|
|
hexchat_plugin_get_info
|
|
</pre>
|
|
|
|
Leave out _hexchat\_plugin\_deinit_ if you don't intend to define that
|
|
function. Then compile your plugin in Visual Studio as usual.
|
|
|
|
**Caveat:** plugins compiled on Win32 **must** have a
|
|
global variable called _ph_, which is the _plugin\_handle_, much like
|
|
in the sample plugin above.
|
|
|
|
## Controlling the GUI
|
|
|
|
A simple way to perform basic GUI functions is to use the _/GUI_ command.
|
|
You can execute this command through the input box, or by calling _hexchat\_command (ph, "GUI .....");_.
|
|
|
|
* **GUI ATTACH:** Same function as "Attach Window" in the HexChat menu.
|
|
* **GUI DETACH:** Same function as "Detach Tab" in the HexChat menu.
|
|
* **GUI APPLY:** Similar to clicking OK in the settings window. Execute this after /SET to activate GUI changes.
|
|
* **GUI COLOR _n_:** Change the tab color of the current context, where n is a number from 0 to 3.
|
|
* **GUI FOCUS:** Focus the current window or tab.
|
|
* **GUI FLASH:** Flash the taskbar button. It will flash only if the window isn't focused and will stop when it is focused by the user.
|
|
* **GUI HIDE:** Hide the main HexChat window completely.
|
|
* **GUI ICONIFY:** Iconify (minimize to taskbar) the current HexChat window.
|
|
* **GUI MSGBOX _text_:** Displays a asynchronous message box with your text.
|
|
* **GUI SHOW:** Show the main HexChat window (if currently hidden).
|
|
|
|
You can add your own items to the menu bar. The menu command has this syntax:
|
|
<pre>
|
|
MENU [-eX] [-i<ICONFILE>] [-k<mod>,<key>] [-m] [-pX] [-rX,group] [-tX] {ADD|DEL} <path> [command] [unselect command]
|
|
</pre>
|
|
|
|
For example:
|
|
|
|
<pre>
|
|
MENU -p5 ADD FServe
|
|
MENU ADD "FServe/Show File List" "fs list"
|
|
MENU ADD FServe/-
|
|
MENU -k4,101 -t1 ADD "FServe/Enabled" "fs on" "fs off"
|
|
MENU -e0 ADD "FServe/Do Something" "fs action"
|
|
</pre>
|
|
|
|
In the example above, it would be recommended to execute _MENU DEL FServe_ inside your _hexchat\_plugin\_deinit_ function. The special item with name "-" will add a separator line.
|
|
|
|
Parameters and flags:
|
|
|
|
* **-eX:** Set enable flag to X. -e0 for disable, -e1 for enable. This lets you create a disabled (shaded) item.
|
|
* **-iFILE:** Use an icon filename FILE. Not supported for toggles or radio items.
|
|
* **-k<mod>,<key>:** Specify a keyboard shortcut. "mod" is the modifier which is a bitwise OR of: 1-SHIFT 4- CTRL 8-ALT in decimal. "key" is the key value in decimal, e.g. -k5,101 would specify SHIFT-CTRL-E.
|
|
* **-m:** Specify that this label should be treated as <a href="http://developer.gnome.org/doc/API/2.0/pango/PangoMarkupFormat.html">Pango Markup</a> language. Since forward slash ("/") is already used in menu paths, you should replace closing tags with an ASCII 003 instead e.g.: hexchat_command (ph, "MENU -m ADD \"<b>Bold Menu<\003b>\"");
|
|
* **-pX:** Specify a menu item's position number. e.g. -p5 will cause the item to be inserted in the 5th place. If the position is a negative number, it will be used as an offset from the bottom/right-most item.
|
|
* **-rX,group:** Specify a radio menu item, with initial state X and a group name. The group name should be the exact label of another menu item (without the path) that this item will be grouped with. For radio items, only a select command will be executed (no unselect command).
|
|
* **-tX:** Specify a toggle menu item with an initial state. -t0 for an "unticked" item and -t1 for a "ticked" item.
|
|
|
|
If you want to change an item's toggle state or enabled flag,
|
|
just _ADD_ an item with exactly the same name and command and specify the _-tX -eX_ parameters you need.
|
|
|
|
It's also possible to add items to HexChat's existing menus, for example:
|
|
|
|
<pre>
|
|
MENU ADD "Settings/Sub Menu"
|
|
MENU -t0 ADD "Settings/Sub Menu/My Setting" myseton mysetoff
|
|
</pre>
|
|
|
|
However, internal names and layouts of HexChat's menu may change in the future, so use at own risk.
|
|
|
|
Here is an example of Radio items:
|
|
|
|
<pre>
|
|
MENU ADD "Language"
|
|
MENU -r1,"English" ADD "Language/English" cmd1
|
|
MENU -r0,"English" ADD "Language/Spanish" cmd2
|
|
MENU -r0,"English" ADD "Language/German" cmd3
|
|
</pre>
|
|
|
|
You can also change menus other than the main one (i.e popup menus). Currently they are:
|
|
|
|
<blockquote>
|
|
<table border=1 cellpadding=4 rules=all>
|
|
<tr bgcolor="#999999"><td>Root Name</td><td>Menu</td></tr>
|
|
<tr><td>$TAB</td><td>Tab menu (right click a channel/query tab or treeview row)</td></tr>
|
|
<tr><td>$TRAY</td><td>System Tray menu</td></tr>
|
|
<tr><td>$URL</td><td>URL link menu</td></tr>
|
|
<tr><td>$NICK</td><td>Userlist nick-name popup menu</td></tr>
|
|
<tr><td>$CHAN</td><td>Menu when clicking a channel in the text area (since 2.8.4)</td></tr>
|
|
</table>
|
|
</blockquote>
|
|
|
|
Example:
|
|
|
|
<pre>
|
|
MENU -p0 ADD "$TAB/Cycle Channel" cycle
|
|
</pre>
|
|
|
|
You can manipulate HexChat's system tray icon using the _/TRAY_ command:
|
|
|
|
<pre>
|
|
Usage:
|
|
TRAY -f <timeout> <file1> [<file2>] Flash tray between two icons. Leave off file2 to use default HexChat icon.
|
|
TRAY -f <filename> Set tray to a fixed icon.
|
|
TRAY -i <number> Flash tray with an internal icon.
|
|
TRAY -t <text> Set the tray tooltip.
|
|
TRAY -b <title> <text> Set the tray balloon.
|
|
</pre>
|
|
|
|
Icon numbers:
|
|
|
|
* 2: Message
|
|
* 5: Highlight
|
|
* 8: Private
|
|
* 11:File
|
|
|
|
For tray balloons on Linux, you'll need libnotify.
|
|
|
|
Filenames can be _ICO_ or _PNG_ format. _PNG_ format is supported on Linux/BSD and Windows XP. Set a timeout of -1 to use HexChat's default.
|
|
|
|
## Handling UTF-8/Unicode strings
|
|
|
|
The HexChat plugin API specifies that strings passed to and from HexChat must be encoded in UTF-8.
|
|
|
|
What does this mean for the plugin programmer? You just have to be a little careful when
|
|
passing strings obtained from IRC to system calls. For example, if you're writing a file-server
|
|
bot, someone might message you a filename. Can you pass this filename directly to open()? Maybe!
|
|
If you're lazy... The correct thing to do is to convert the string to "system locale encoding",
|
|
otherwise your plugin will fail on non-ascii characters.
|
|
|
|
Here are examples on how to do this conversion on Unix and Windows. In this example, someone will
|
|
CTCP you the message "SHOWFILE <filename>".
|
|
|
|
<pre>
|
|
static int
|
|
ctcp_cb (char *word[], char *word_eol[], void *userdata)
|
|
{
|
|
if(strcmp(word[1], "SHOWFILE") == 0)
|
|
{
|
|
get_file_name (nick, word[2]);
|
|
}
|
|
|
|
return HEXCHAT_EAT_HEXCHAT;
|
|
}
|
|
|
|
static void
|
|
get_file_name (char *nick, char *fname)
|
|
{
|
|
char buf[256];
|
|
FILE *fp;
|
|
|
|
/* the fname is in UTF-8, because it came from the HexChat API */
|
|
|
|
#ifdef _WIN32
|
|
|
|
wchar_t wide_name[MAX_PATH];
|
|
|
|
/* convert UTF-8 to WIDECHARs (aka UTF-16LE) */
|
|
if (MultiByteToWideChar (CP_UTF8, 0, fname, -1, wide_name, MAX_PATH) < 1)
|
|
{
|
|
return;
|
|
}
|
|

|
|
|
### hexchat\_hook\_command ()
|
|
|
|
**Prototype:** hexchat\_hook \*hexchat\_hook\_command (hexchat\_plugin \*ph, const char \*name, int pri, hexchat\_cmd\_cb \*callb, const char \*help\_text, void \*userdata);
|
|
|
|
**Description:** Adds a new _/command_. This allows your program to
|
|
handle commands entered at the input box. To capture text without a "/" at
|
|
the start (non-commands), you may hook a special name of "". i.e _hexchat\_hook\_command (ph, "", ...);_.
|
|
|
|
Commands hooked that begin with a period ('.') will be hidden in _/HELP_ and _/HELP -l_.
|
|
|
|
**Arguments:**
|
|
|
|
* **ph:** Plugin handle (as given to _hexchat\_plugin\_init ()_).
|
|
* **name:** Name of the command (without the forward slash).
|
|
* **pri:** Priority of this command. Use _HEXCHAT\_PRI\_NORM_.
|
|
* **callb:** Callback function. This will be called when the user executes the given command name.
|
|
* **help\_text:** String of text to display when the user executes _/HELP_ for this command. May be NULL if you're lazy.
|
|
* **userdata:** Pointer passed to the callback function.
|
|
|
|
**Returns:** Pointer to the hook. Can be passed to _hexchat\_unhook ()_.
|
|
|
|
**Example:**
|
|
|
|
<pre>
|
|
static int
|
|
onotice_cb (char *word[], char *word_eol[], void *userdata)
|
|
{
|
|
if (word_eol[2][0] == 0)
|
|
{
|
|
hexchat_printf (ph, "Second arg must be the message!\n");
|
|
return HEXCHAT_EAT_ALL;
|
|
}
|
|
|
|
hexchat_commandf (ph, "NOTICE @%s :%s", hexchat_get_info (ph, "channel"), word_eol[2]);
|
|
return HEXCHAT_EAT_ALL;
|
|
}
|

|
|
* **hexchatdirfs:** HexChat config directory, e.g.: /home/user/.config/hexchat. This string is encoded in local file system encoding, making it ideal for direct use with functions like open() or OpenFile(). For real Unicode support on Windows, it's best not to use hexchatdirfs, but hexchatdir instead.
|
|
* **host:** real hostname of the server you connected to.
|
|
* **inputbox:** the input-box contents, what the user has typed.
|
|
* **libdirfs:** library directory. e.g. /usr/lib/hexchat. The same directory used for auto-loading plugins. This string isn't necessarily UTF-8, but local file system encoding.

|
* **network:** current network name or NULL.
|
|
* **nick:** your current nick name.

|
|
**Arguments:**
|
|

**Quote from RFC1459:**
|
|
>Because of IRC's scandanavian origin, the characters {}| are
|
|
considered to be the lower case equivalents of the characters []\,
|
|
respectively. This is a critical issue when determining the
|

{
|
|
char *new_text;
|
|
|
|
/* strip both colors and attributes by using the 0 and 1 bits (1 BITWISE-OR 2) */
|
|
new_text = hexchat_strip (ph, "\00312Blue\003 \002Bold!\002", -1, 1 | 2);
|
|
|
|
if (new_text)
|
|
{
|
|
/* new_text should now contain only "Blue Bold!" */

|
*plugin_version = "1.0";
|
|
|
|
hexchat_pluginpref_set_str (ph, "myvar1", "I want to save this string!");
|
|
hexchat_pluginpref_set_str (ph, "myvar2", "This is important, too.");
|
|
|
|
return 1; /* return 1 for success */
|
|
}
|
|
</pre>
|
|
|
|
In the example above, the settings will be saved to the plugin_tester_thingie.conf file, and its content will be:

char list[512];
|
|
char buffer[512];
|
|
char *token;
|
|
|
|
hexchat_pluginpref_list (ph, list);
|
|
hexchat_printf (ph, "Current Settings:\n");
|
|
token = strtok (list, ",");
|
|
|
|
while (token != NULL)
|
|
{
|
|
hexchat_pluginpref_get_str (ph, token, buffer);
|
|
hexchat_printf (ph, "%s: %s\n", token, buffer);
|
|
token = strtok (NULL, ",");
|
|
}
|
|
}
|
|
</pre>
|
|
|
|
In the example above we query the list of currently stored settings, then print them one by one with their respective values. We always use _hexchat\_pluginpref\_get\_str ()_, and that's because we can read an integer as string (but not vice versa).
