Tcl/Tk

After over twenty years since its release, Tcl still has a vibrant and active user community in both academia and industry. Tcl is frequently a hidden "secret sauce" inside commercial applications, providing the graphics and control infrastructure. The Tcl API has been evolving for many years. With the 9.0 release, these changes become real, updating the C API for the first time since Tcl 8.0 was released in the early 1990s, and the Fourth Edition is newly updated with over 150 pages of material on the latest Tcl extensions. Tcl/Tk: A Developer’s Guide is a unique practical tutorial for professional programmers and beginners alike. Starting with a clear picture of the basics, Tcl/Tk covers the variety of tools in this "Swiss army knife" of programming languages, giving readers the ability to enhance programs, extend application capabilities, and become more effective programmers. Extensive code snippets and online tutorials in various languages will give readers a firm grasp on how to use the Tcl/Tk libraries and interpreters and, most importantly, on what constitutes an effective strategy for using Tcl/Tk. This all-new Fourth Edition of Tcl/Tk: A Developer's Guide includes information on adopting the new language features that are not yet documented by other books. The Fourth Edition includes, new Tcl features and expanded the Tcl-OO coverage, a new chapter on web tech, discussing using Rivet and SQLite for a database-backed website, a new chapter on AI and Cloud, with an example of using Tcl to control an AI library on AWS, and many more updates throughout. Tcl/Tk (Tool Command Language/Tool Kit) makes it fast and easy to implement any type of application, from games to network analyzers. Tcl/Tk is a full-bodied, mature programming platform used by NASA rocket scientists, Wall Street database experts, Internet designers, and open source programmers around the world. Tcl/Tk's multi-faceted and extensible nature make it ideal for developing end-user GUIs, client/server middleware, Web applications, and more. Readers can code completely in Tcl, use any of hundreds of extensions, call C or Java subroutines from Tcl/Tk, or use Tcl to glue legacy applications together. Written from a programmer's perspective, Tcl/Tk: A Developer's Guide describes how to use Tcl's standard tools and the unique features that make Tcl/Tk powerful: including graphics widgets, packages, namespaces, and extensions. With this book an experienced programmer will be able to code Tcl in a few hours.
