Scriptics Corp has introduced new versions of the open source Tcl scripting language and its TclPro development toolset. Mountain View California-based Scriptics, run by Tcl’s creator John Ousterhout, is now offering improved I/O performance and security for internet applications written using TCI, along with Y2K compliance testing for Tcl applications. Tcl 8.2’s extended I/O system, called Trf, delivers I/O compression and encryption. TclPRo 1.3, which works with 8.2, includes the Y2K compliance checker along with improved script debugging, and the first implementation work for TEA – the Tcl Extension Architecture. TEA is intended to offer programmers an easier way of creating and sharing Tcl extensions, and for deploying multiple extensions in a single Tcl application. Prices for the development tool start at $1,500 for a single user license.
