  18 You can extend SimGrid without modifying it, thanks to our plugin
  19 mechanism. This page describes how to write your own plugin, and
  20 documents some of the plugins distributed with SimGrid:
  21
  22   - :ref:`Host Load <plugin_host_load>`: monitors the load of the compute units.
  23   - :ref:`Host Energy <plugin_host_energy>`: models the energy dissipation of the compute units.
  24   - :ref:`Link Energy <plugin_link_energy>`: models the energy dissipation of the network.
  25   - :ref:`WiFi Energy <plugin_link_energy_wifi>`: models the energy dissipation of wifi links.
  26   - :ref:`Battery <plugin_battery>`: models batteries that get discharged by the energy consumption of a given host.
  27   - :ref:`Solar Panel <plugin_solar_panel>`: models solar panels which energy production depends on the solar irradiance.
  28   - :ref:`Chiller <plugin_chiller>`: models chillers which dissipate heat by consuming energy.
  29
  30 You can activate these plugins with the :ref:`--cfg=plugin <cfg=plugin>` command
  31 line option, for example with ``--cfg=plugin:host_energy``. You can get the full
  32 list of existing plugins with ``--cfg=plugin:help``.

  34 Defining a Plugin
  35 *****************
  36
  37 A plugin can get some additional code executed within the SimGrid
  38 kernel, and attach the data needed by that code to the SimGrid
  39 objects.
  40
  41 The host load plugin in
  42 `src/plugins/host_load.cpp <https://framagit.org/simgrid/simgrid/tree/master/src/plugins/host_load.cpp>`_
  43 constitutes a good introductory example. It defines a class
  44 ``HostLoad`` that is meant to be attached to each host. This class
  45 contains a ``EXTENSION_ID`` field that is mandatory to our extension
  46 mechanism. Then, the function ``sg_host_load_plugin_init``
  47 initializes the plugin. It first calls
  48 :cpp:func:`simgrid::s4u::Host::extension_create()` to register its
  49 extension to the ``s4u::Host`` objects, and then attaches some
  50 callbacks to signals.
  51
  52 You can attach your own extension to most kinds of s4u object:
  53 :cpp:class:`Actors <simgrid::s4u::Actor>`,
  54 :cpp:class:`Disks <simgrid::s4u::Disk>`,
  55 :cpp:class:`Hosts <simgrid::s4u::Host>` and
  56 :cpp:class:`Links <simgrid::s4u::Link>`. If you need to extend another
  57 kind of objects, please let us now.
  58
  59 .. cpp:class:: template<class R, class... P> simgrid::xbt::signal<R(P...)>
  60
  61   A signal/slot mechanism, where you can attach callbacks to a given signal, and then fire the signal.
  62
  63   The template parameter is the function signature of the signal (the return value currently ignored).
  64
  65 .. cpp:function::: template<class R, class... P, class U>  unsigned int simgrid::xbt::signal<R(P...)>::connect(U slot)
  66
  67   Add a new callback to this signal.
  68
  69 .. cpp:function:: template<class R, class... P> simgrid::xbt::signal<R(P...)>::operator()(P... args)
  70
  71   Fire that signal, invoking all callbacks.
