Plugins Development
First of all, to understand what is discussed on this Section, is mandatory to read first the section called Plugins System. Otherwise you'll miss the basics and probably will not understand what is explained here. On that section there is a simple explanation and an overview about how the plugins system works. After reading that, you can continue reading here...
On this Wiki section, we assume you've read the overview and you know about the existence of the different "hooking" methods.
Here, we'll provide the needed info to be able to create a custom plugin for airgeddon. The explanations will be based on an example plugin which was already created and is existing on this repository. The plugin was created as a PoC (Proof Of Concept) about how to develop a plugin. It is called Missing Dependencies and it is included directly into airgeddon. You can check it anytime if you have doubts about how a plugin should be developed. It is available from airgeddon>=10.0.
A plugin creation template will be provided in order to ease the task. The Plugin Creation Template can be used as "skeleton" of your plugin. Rename or copy it to any other name on the same plugins directory keeping the .sh extension.
The plugin template contains detailed instructions about how to proceed. Read them carefully. It is separated by sections.
First lines of the template are to set some basic vars. The description of each one is self explanatory:
###### GENERIC PLUGIN VARS ######
plugin_name="Set your plugin name here"
plugin_description="Set a short description of your plugin"
plugin_author="Set your nick/name here"
#Enabled 1 / Disabled 0 - Set this plugin as enabled - Default value 1
plugin_enabled=1
Each plugin can be enabled/disabled setting plugin_enabled var to 1or 0, but bear in mind that the plugins system can be enabled/disabled globally using the AIRGEDDON_PLUGINS_ENABLED option. More info at Wiki Options Section.
This section will be used to set some requirements for the plugin. It means that the plugin will be active only if the requirements are met. This is useful to apply plugin effects only to some airgeddon versions or to a concrete Linux distribution:
###### PLUGIN REQUIREMENTS ######
#Set airgeddon versions to apply this plugin (leave blank to set no limits, minimum version recommended is 10.0 on which plugins feature was added)
plugin_minimum_ag_affected_version="10.0"
plugin_maximum_ag_affected_version=""
#Set only one element in the array "*" to affect all distros, otherwise add them one by one with the name which airgeddon uses for that distro (examples "BlackArch", "Parrot", "Kali")
plugin_distros_supported=("*")
The complete list of the available Linux distributions can be found in airgeddon.sh file at arrays called known_compatible_distros and known_arm_compatible_distros.
The explanation of this section is simple. It's just to create your new custom functions. We must differentiate between new custom functions and "hooked" functions (explained on the next section).
###### CUSTOM FUNCTIONS ######
#Just create here new custom functions if they are needed
#They can be called from the plugin itself. They are different than the "hooked" functions (explained on the next section)
This section can be avoided if you only need to hook functions.
This kind of hooking will prevent the original code from an airgeddon function to be executed. The defined code here will be executed instead.

airgeddon has some mechanisms to avoid errors during plugins development. It can detect if you try to "hook" a non existing function and an error will be shown. If you try to "hook" to perform same action over a function (prehook for example) from two different plugins, airgeddon will show you an error alerting to you about that untenable situation.
If you have problems during your plugin development, please consider to contact us on IRC or Discord channel. More info at Wiki Contact Section. Don't open an issue for this! Remember that we are not going to teach you about how to be a developer!.
