Tcl (Tool Command Language) is a scripting language with its own built-in interpreter that's used to develop applications easily. As a language, it is very similar to UNIX shell languages. It glues together blocks of code built into system programming languages like C, C++, and Java. Tk is the Tcl toolkit for building graphical interfaces. It makes GUI programming easier, and it lets developers and programmers create interfaces that look and perform better. Tcl/Tk's new ability to interact with Java is rapidly increasing the user base - particularly for Web developers and programmers - of this already popular scripting language. Because Tcl/Tk lets you do what no other language (except Java) lets you do - create programs that can be independent of both graphical hardware and operating systems - it is an ideal tool for Web development. With Web development as its main focus, this book brings programmers and developers the practical, real-world examples they need. It covers topics such as: how to write a complete Web browser in Tcl; writing Tclets (Tcl applets); creating GUI components; plug-ins that handle Tclets; and how to use Tcl to interact with Java, JavaScript, and CGI/Perl.
