= !TclBind = !TclBind is a connection between the Tcl library (read [http://www.tcl.tk this] for more information) and Orxonox. Tcl is used by the [wiki:CommandExecutor] to execute nested commands and scripts. There are two important C++ functions in !TclBind: * '''tcl('''''command''''')''': Executes a tcl command (also available as a [wiki:ConsoleCommand]) * '''eval('''''command''''')''': Executes a tcl command and returns the returnvalue On the other hand, !TclBind defines some new Tcl procedures: * '''execute''' ''command'': Executes a !ConsoleCommand in the !CommandExecutor * '''query''' ''command'': Executes a !ConsoleCommand in the !CommandExecutor and returns the returnvalue * '''crossquery''' ''id'' ''command'': Sends a command to another Tcl interpreter (see [wiki:TclThreadManager]) If Tcl finds an unknown procedure, it automatically passes the command via '''execute''' to the [wiki:CommandExecutor]. This allows you to call Orxonox commands within Tcl wihtout defining a Tcl alias for every Orxonox command. Additionally the native Tcl procedure '''puts''' sends it's output to the [wiki:Output orxout()] instead of directly using the standard output device.
