     35    @file
     36    @ingroup Command ConsoleCommand
     37    @brief Declaration of the orxonox::ConsoleCommand class and the SetConsoleCommand() macro.
     38
     39    @anchor ConsoleCommandExample
     40
     41    Console commands can be used to write scripts, use key-bindings or simply to be
     42    entered into the shell by the user. Instances of orxonox::ConsoleCommand define
     43    the function of a command, and also more information like, for example, if it is
     44    active, default values, and possible arguments.
     45
     46    Commands need to be registered to the system statically on startup by using the
     47    SetConsoleCommand() or DeclareConsoleCommand() macros outside of a function.
     48    This ensures that commands are known to the system at any time, so they can be
     49    evaluated (see orxonox::CommandExecutor::evaluate()), for example for key-bindings.
     50
     51    Example:
     52    @code
     53    void myCoutFunction(const std::string& text)        // Define a static function
     54    {
     55        COUT(0) << "Text: " << text << std::endl;       // Print the text to the console
     56    }
     57
     58    SetConsoleCommand("cout", &myCoutFunction);         // Register the function as command with name "cout"
     59    @endcode
     60
     61    Now you can open the shell and execute the command:
     62    @code
     63    $ cout Hello World
     64    @endcode
     65
     66    Internally this command is now passed to orxonox::CommandExecutor::execute():
     67    @code
     68    CommandExecutor::execute("cout HelloWorld");
     69    @endcode
     70
     71    CommandExecutor searches for a command with name "cout" and passes the arguments
     72    "Hello World" to it. Because we registered myCoutFunction() with this command,
     73    as a result the following text will be printed to the console:
     74    @code
     75    Text: Hello World
     76    @endcode
     77
     78    You can add more attributes to the ConsoleCommand, by using the command-chain feature
     79    of SetConsoleCommand(). For example like this:
     80    @code
     81    SetConsoleCommand("cout", &myCoutFunction)
     82        .addGroup("output", "text")
     83        .accessLevel(AccessLevel::Offline)
     84        .defaultValues("no text");
     85    @endcode
     86
     87    Open the shell again and try it:
     88    @code
     89    $ cout Hello World
     90    Text: Hello World
     91    $ output text Hello World
     92    Text: Hello World
     93    $ cout
     94    Text: no text
     95    @endcode
     96
     97    If you execute it online (note: the access level is "Offline"), you will see the
     98    following (or something similar):
     99    @code
     100    $ cout Hello World
     101    Error: Can't execute command "cout", access denied.
     102    @endcode
     103
     104    If a command is executed, the arguments are passed to an underlying function,
     105    whitch is wrapped by an orxonox::Functor which again is wrapped by an orxonox::Executor.
     106    The Functor contains the function-pointer, as well as the object-pointer in
     107    case of a non-static member-function. The executor stores possible default-values
     108    for each argument of the function.
     109
     110    The function of a command can be changed at any time. It's possible to just exchange
     111    the function-pointer of the underlying Functor if the headers of the functions are
     112    exactly the same. But you can also exchange the Functor itself or even completely
     113    replace the Executor. Also the other attributes of a ConsoleCommand can be modified
     114    during the game, for example it can be activated or deactivated.
     115
     116    To do so, the function ModifyConsoleCommand() has to be used. It returns an instance
     117    of orxonox::ConsoleCommand::ConsoleCommandManipulator which has an interface similar to
     118    orxonox::ConsoleCommand, but with slight differences. You can use it the same way like
     119    SetConsoleCommand(), meaning you can use command-chains to change different attributes at
     120    the same time. ModifyConsoleCommand() must not be executed statically, but rather in a
     121    function at some point of the execution of the program.
     122
     123    Example:
     124    @code
     125    void myOtherCoutFunction(const std::string& text)                       // Define a new static function
     126    {
     127        COUT(0) << "Uppercase: " << getUppercase(text) << std::endl;        // Print the text in uppercase to the console
     128    }
     129
     130    {
     131        // ...                                                              // somewhere in the code
     132
     133        ModifyConsoleCommand("cout").setFunction(&myOtherCoutFunction);     // Modify the underlying function of the command
     134
     135        // ...
     136    }
     137    @endcode
     138
     139    If you now enter the command into the shell, you'll see a different behavior:
     140    @code
     141    $ cout Hello World
     142    Uppercase: HELLO WORLD
     143    $ cout
     144    Uppercase: NO TEXT
     145    @endcode
     146
     147    A few important notes about changing functions:
     148
     149    Instead of changing the function with setFunction(), you can also create a command-stack
     150    by using pushFunction() and popFunction(). It's important to note a few things about that,
     151    because the underlying structure of Executor and Functor has a few pitfalls:
     152     - If you push a new function-pointer, the same executor as before will be used (and, if
     153       the headers match, even the same functor can be used, which is very fast)
     154     - If you push a new Functor, the same executor as before will be used
     155     - If you push a new Executor, everything is changed
     156
     157    Note that the executor contains the @b default @b values, so if you just exchange the
     158    Functor, the default values remain the same. However if you decide to change the default
     159    values at any point of the stack, <b>this will also change the default values on all
     160    other stack-levels</b> that share the same executor. If you don't like this behavior,
     161    you have to explicitly push a new executor before changing the default values, either by
     162    calling pushFunction(executor) or by calling pushFunction(void) which pushes a copy of
     163    the current executor to the stack.
     164
     165    Another important point are object pointers in case of non-static member-functions.
     166    Whenever you set or push a new function, <b>you must add the object pointer again</b>
     167    because objects are stored in the Functor which is usually exchanged if you change
     168    the function.
     169
     170    You can also use a stack for objects, but note that this <b>object-stack is different for each
     171    function</b> - so if you set a new function, the object-stack will be cleared. If you push
     172    a new function, the old object-stack is stored in the stack, so it can be restored if
     173    you pop the function.
     174
     175    %DeclareConsoleCommand():
     176
     177    Appart from SetConsoleCommand() you can also call DeclareConsoleCommand(). In contrast
     178    to SetConsoleCommand(), this doesn't assign a function to the command. Indeed you have
     179    to pass a function-pointer to DeclareConsoleCommand(), but it is only used to determine
     180    the header of the future command-function. This allows to declare a command statically,
     181    thus it's possible to evaluate key-bindings of this command, but the actual function
     182    can be assigned at a later point.
     183
     184    Example:
     185    @code
     186    DeclareConsoleCommand("cout", &prototype::void__string);
     187    @endcode
     188
     189    If you try to execute the command now, you see the following (or something similar):
     190    @code
     191    $ cout Hello World
     192    Error: Can't execute command "cout", command is not active.
     193    @endcode
     194
     195    You first have to assign a function to use the command:
     196    @code
     197    {
     198        // ...
     199
     200        ModifyConsoleCommand("cout").setFunction(&myCoutFunction);
     201
     202        // ...
     203    }
     204    @endcode
     205
     206    Now you can use it:
     207    @code
     208    $ cout Hello World
     209    Text: Hello World
     210    @endcode
     211
     212    Note that the initial function prototype::void__string is defined in the namespace
     213    orxonox::prototype. If there's no function with the desired header, you can extend
     214    the collection of functions or simply use another function that has the same header.
