TclX--General Purpose Extensions
Extended Tcl, or TclX, is a set of extensions to Tcl. TclX is oriented towards system programming tasks and large application development. Extended Tcl provides many interfaces to the operating system that Tcl does not, and is upward compatible with Tcl. You can run extended Tcl interactively using either the tclsh or sgitcl command. In fact tclsh is a link to sgitcl. See the tclX(3Tcl) reference page for more information.
To get a feel for interactive Tcl, click on the red text of tclsh to run the extended Tcl shell.
TclX offers the following features, which plain Tcl does not:
- a shell (tclsh) for developing and executing Tcl programs
- a code library facility for building large applications
- access to POSIX system calls
- file I/O commands
- time and date facilities
- string and character manipulation
- awk-like pattern scanning
- extended list manipulation commands
- keyed lists (similar to C structures in functionality)
- command for accessing TCP/IP servers
- XPG internationalization commands
- debugging and profiling facilities
- a help system
You can use TclX in conjunction with Tk and Tm, described below.
