Modules are most commonly interfaced with by messaging a special user on irc. For example, to view the highlight keywords in your watch list, you'd send ''/msg *watch list''. When znc sees that the nick you're msging starts with an asterisk, it doesn't forward the message to the ircd but instead sends it to the proper module for processing. In this case, the watch module will get the message and reply to you with a listing of your keywords. This makes for a very convenient and standard way of configuring or otherwise communicating with your loaded modules as well as a common and standard way for your loaded modules to display status or other information back to you. Notice that we said "loaded modules" which brings up the point that you first have to ''/znc loadmod watch'' before you can interface with the watch module. Most modules will reply to ''/msg *module help'' with a listing of commands.
'''Modules''' are used to extend and modify the way ZNC functions. Users interact with modules most commonly by messaging a special user on IRC. For example, to view the highlight keywords in your watch list, you'd send ''/msg *watch list''. When ZNC sees that the nick you're messaging starts with an asterisk, it doesn't forward the message to the IRCd/server but instead sends it to the proper module for processing. In this case, the watch module will get the message and reply to you with a listing of your keywords. This makes for a very convenient and standard way of configuring or otherwise communicating with your loaded modules, as well as a common and standard way for your loaded modules to display status or other information. Notice that this is for loaded modules. You must load a given module, for example ''/znc loadmod watch'', before you can interface with the watch module. Most modules will reply to ''/msg *module help'' with a listing of available commands.


ZNC modules are loaded either globally, per-network or on a per-user basis. Each module itself defines whether it is global, network or user specific. User level and network modules can do things ranging from [[crypt|manipulating the incoming/outgoing messages]] to implementing a full blown [[twitter]] client. They can also do more traditional irc tasks such as [[autoop|challenge based auto-op]], [[simple_away|setting you away]], or [[log|logging to disk]]. Each user gets to load and configure their own set of modules to customize their experience to suit their preference.
ZNC modules are loaded either '''globally''', '''per-network''', or on a '''per-user''' basis. Each module defines for itself whether it is available to load as global, network-specific and/or user-specific.

They can also do more traditional IRC tasks such as [[autoop|challenge based auto-op]], [[simple_away|setting you away]], or [[log|logging to disk]]. Each user gets to load and configure their own set of modules to customize their experience to suit their preference.


Global modules are loadable by admins and provide functionality or change behavior for all users. For example, the [[partyline]] module has to be global since it provides functionality for all users on a given znc instance to be able to communicate with each other from within znc itself. Global modules can do everything that user level modules can do as well as a few extras. They can replace ZNC's [[imapauth|authentication system]], modify the config writing process, deal with CAP, etc.

The modules can also hook into znc's [[WebMods|web interface]] and provide web content. The most common web module is [[webadmin]] which allows admins to add/remove users and allows users to configure their settings from a browser.

ZNC modules are written in C++ natively. There are also a couple of modules that embed an interpreter to allow you to load perl, python or tcl modules. To learn more about creation of modules you should read [[modperl|Perl Modules]], [[modpython|Python Modules]], [[modtcl|TCL Modules]], or [[Writing modules|C++ Modules]]. Feel free to create wikipages about modules you created, but don't forget to add a download link, contact information and use the same layout as the rest of the modules. Contributions are always much appreciated.

Overview

Modules are used to extend and modify the way ZNC functions. Users interact with modules most commonly by messaging a special user on IRC. For example, to view the highlight keywords in your watch list, you'd send /msg *watch list. When ZNC sees that the nick you're messaging starts with an asterisk, it doesn't forward the message to the IRCd/server but instead sends it to the proper module for processing. In this case, the watch module will get the message and reply to you with a listing of your keywords. This makes for a very convenient and standard way of configuring or otherwise communicating with your loaded modules, as well as a common and standard way for your loaded modules to display status or other information. Notice that this is for loaded modules. You must load a given module, for example /znc loadmod watch, before you can interface with the watch module. Most modules will reply to /msg *module help with a listing of available commands.

ZNC modules are loaded either globally, per-network, or on a per-user basis. Each module defines for itself whether it is available to load as global, network-specific and/or user-specific. User level and network modules can do things such as manipulating the incoming/outgoing messages. They can also do more traditional IRC tasks such as challenge based auto-op, setting you away, or logging to disk. Each user gets to load and configure their own set of modules to customize their experience to suit their preference.

Global modules are loadable by admins and provide functionality or change behavior for all users. For example, the partyline module has to be global since it provides functionality for all users on a given ZNC instance to be able to communicate with each other from within ZNC itself. Global modules can do everything that user-level modules can do, as well as a few extras. They can replace ZNC's authentication system, modify the config-writing process, deal with CAP, etc.

The modules can also hook into ZNC's web interface and provide web content. The most common web module is webadmin which allows admins to add/remove users and allows users to configure their settings from a browser.

Developers

ZNC modules are written in C++ natively. There are also a couple of modules that embed an interpreter to allow you to load Perl, Python, or Tcl modules. To learn more about creation of modules you should read Perl Modules, Python Modules, TCL Modules, or C++ Modules.

Feel free to create wikipages about modules you have created, but don't forget to add a download link, contact information, and use the same layout as the rest of the modules. Contributions are always much appreciated.

More Modules

For more modules, see Category:Modules.

Managing Modules

Modules can be added or removed easily. Modules can be stored in ~/.znc/modules and /usr/local/lib/znc by default. ZNC installs its modules to that second directory, which in fact is ${prefix}/lib/znc, but this can be changed with ./configure --module-prefix=DIR before compiling.

ZNC will first look in the local sub-directory modules when searching for modules. Only files that end with ".so" will be seen as a module. To remove modules you can simply delete them from the folder. No other configuration changes or restarts are necessary. To remove, but also keep a module for later use you can also change the name, like: mv sample.so sample.so_.

To compile a new module you must first save the source as a ".cpp" file. Compiling modules describes the process in detail.

(Un)Loading Modules

Global, user, and network modules can be (un)loaded from webadmin or via the *status query window, like:

/msg *status LoadMod [--type=global|user|network] <module> <parameters>
/msg *status UnloadMod [--type=global|user|network] <module>
  • * is the StatusPrefix set in your configuration. Usually it's just an asterisk ("*").
  • [--type=global|user|network] optionally specifies whether to (un)load the module as a global, user, or network module. Not all modules can be loaded at all levels; see individual Module documentation to find out where it may be loaded.
  • <module> is based on the modules file name, excluding the ".so" extension.
  • <parameters> are specific for each module and not required: You can provide parameters when loading the module, or you can set up the module after loading it.

So, to load the log module at the global level (as opposed to user or network) and remove all color/formatting control codes with the -sanitize parameter, you would type:

/msg *status LoadMod --type=global log -sanitize

For older versions of ZNC, you won't have the option to specify [--type=global|user|network]. In that case, just use:

/msg *status LoadMod <module> <parameters>
/msg *status UnloadMod <module>

Please keep in mind that a user is not able to load a module if the directive "DenyLoadMod" is set to true. Trying to load a module will fail with "Unable to load [<module>] Access Denied.".

If a module prevents ZNC from starting up and therefore you can't unload the module using webadmin, you can edit znc.conf and remove the corresponding LoadModule line.


Modules run in the order they are loaded /msg *status listmods starting with global modules, then user modules, and finally network modules.

Example: The crypt module is a network module. If the log module is loaded as a network module AFTER the crypt module then all encrypted conversations are logged in plain text on the znc server.

Using modules

It is recommended to read the module's wikipage if you want to find out how a module works. Alternatively the following command can be used to get a command list:

/msg *<module> help
  • * is the StatusPrefix set in your configuration. Usually it's just an asterisk ("*").
