Plug-In Commands3 PLUG-IN COMMANDSThese commands are provided through plug-in modules. These plug-ins do not haveto be loaded, but provide extra functionality if they are.For an example of how to create a Tcl/Tk script, see <strong>Scripting</strong> chapter of the UserGuide.3.1 TCLSYNTAXtcl [args]EXPLANATIONThis command allows you to run scripts written in the Tcl language from withinHoudini, and is useful for customising Houdini’s interface and dialog boxes.Tcl starts a tcl shell with the arguments given. There is an additional command in tcl“hscript” which can be used to run any Houdini command. tcl is a public domainscripting language which has many powerful features (see tk).You can run a sample Tcl script by typing tk hbrowser.tk in the Textport. This scriptsimply brings up a Þle requester style browser which shows the Houdini objectsinstead of Þles. By double clicking on an object, you will see the contents of theobject. This is a quick way of seeing what objects are available.Tcl is a scripting language which is in common use around the world. Tk is anextension to Tcl which allows you to create Windows and interface elementsthrough the scripting language. You should be able to Þnd books that discuss Tcl/Tk(commonly pronounced “tickle”) in any computer book store.3.2 TKSYNTAXtk [args]EXPLANATIONTk is a version of Tcl which supports X11 and Motif extensions. This allows you tobuild custom user interfaces in scripts. Again, there are several books whichdescribe the tk language as well as a wealth of information on the world wide web.There are some simple example scripts installed in $HH/scripts/tk .12 - <strong>Scripting</strong> 2 123
