Tcl/SMAPI is a Tcl extension library that makes possible the use of the IBM Speech Manager API (SMAPI) in Tcl scripts. IBM is using Tcl/SMAPI in automating the testing of the speech recognition engine, both off-line and on-line. Using simple Tcl scripts, it is possible to interact with the ViaVoice speech recognition engine in a platform-independent manner. Developers may also use Tcl/SMAPI to quickly prototype graphical, speech aware applications using Tcl/Tk. In addition, using the Tcl language, general purpose speech applications can be developed, including, for example, client/server systems. A simple graphical dictation window is included with Tcl/SMAPI to illustrate the use of Tcl/SMAPI with the Tcl/Tk wish interpreter.
Tcl provides a portable scripting environment for Unix, Windows, and Macintosh that supports string processing and pattern matching, native file system access, shell-like control over other programs, TCP/IP networking, timers, and event-driven I/O. Tcl has traditional programming constructs like variables, loops, procedures, namespaces, error handling, script packages, and dynamic loading of DLLs. Tk provides portable GUIs on UNIX, Windows, and Macintosh. A powerful widget set and the concise scripting interface to Tk make it a breeze to develop sophisticated user interfaces.
The tclreadline package makes the GNU readline facilities available for interactive Tcl shells. This includes history expansion and file/command completion. Command and subcommand completion is provided for all Tcl/Tk commands. Command completion can be easily added for user-defined commands.
The Nebula Device is a free multiplatform game engine currently running under Linux and Windows. It uses OpenGL and/or Direct3D for rendering and Tcl/Tk for scripting. Living C++ objects can be browsed and manipulated at runtime from the builtin console, or remotedly from a minimal terminal based console app. A powerful channel animation system allows any floating point attribute to be animated, and specialized animator classes allow things like realtime bone animation with weighted vertex skin.
trf is an extension library to the script language tcl, as created by John Ousterhout. It extends the language at the C-level with so-called "transformer"-procedures. With the help of some patches to the core the package is able to intercept all read/write operations on designated channels, thus giving it the ability to transform the buffer contents as desired. Existing transforms include Base64, UUencode, Hashes (SHA, MD5, ...), error correction codec, zlib-based compression, script level transforms.
