Tcl Logo


Release date: November 22, 1999

An add-on disk for the muLinux system, containing a mix of application programs, all written in Tool Command Language, aka, Tcl (pronounced as tickle.)

Download TCL.tgz now!
You probably need to 'Shift-Click' the link to download it!!.

Note TCL.tgz is compressed using bzip2. The '.tgz' extension is used to fool web servers in sending the file as binary.


You'll need a working muLinux system. Beginning with muLinux 7.x, Tcl-To-Go is fully supported. Tcl-To-Go also requires the muLinux X11 add-on disk, as most of the programs on Tcl-To-Go are based on X11.

Tcl-To-Go fits on a single floppy, formatted with 1722 1k blocks. To format such a floppy use the following command in Linux:

fdformat /dev/fd0H1722

To complete the installation, simply copy TCL.tgz onto your super-formatted floppy:

dd if=TCL.tgz of=/dev/fd0H1722 bs=21k

If you would like to unpack TCL.tgz on your hard disk for inspection, use the muLinux mu script, or simply

cat TCL.tgz | bzip2 -d | tar xf -

If your Linux system doesn't include the /dev/fd0H1722 device, try building it with

cd /dev; ./MAKEDEV fd0

What can you do with Tcl-To-Go?

Here are some sample screenshots, illustrating some of the applications on Tcl-To-Go (click on the snapshot thumbnail image for a full 640x480 screen dump.)

Tcl Development
Text editing
News and Mail
Network clients
Web serving and HTML editing

Plus many other fine programs and utilities not shown.

How is it done?

Compress, compress again, then compress some more. Tcl applications and library files are stored as compressed (gzip) files, even after the Tcl-To-Go floppy is loaded into your muLinux system. Tcl-To-Go modifies Tcl run-time libraries to recognize compressed files, and uncompress them on the fly. Tcl-To-Go fits over six megabytes of Tcl code onto a single super-formatted floppy. This of course includes the Tcl/Tk interpreters, tclsh and wish. When the floppy is installed, its filesystem space is less than 3000 1k blocks.

Grateful Acknowledgements

My thanks goes to all of the folks that created the applications that I'm including on Tcl-To-Go. Please note the authors of each application below.

Other Notes

The application mix of programs may change from release to release. In particular, the current release has some applications that overlap, e.g., tkpaint and impress, dirc and netplug, etc. Please let me know which applications you find most useful.

Documentation: skimpy at best. I've taken the tack that most applications are either intuitive to use, or can be figured out with a minimum of exploration. Therefore, I've sacrificed documentation in favor of providing additional applications. Still, many applications contain their own help systems. Please refer to the original distributions of each application as a way to get more information.

Support: please use the muLinux mailing list for all questions about Tcl-To-Go. Subscribe to the mailing list by sending an email to:

The Whole Shebang

Here are the current mix of applications on TCL.tgz.
This is the README file included on the Tcl-To-Go disk image:


Tom Poindexter,
1st edition, Nov. 1999

An add-on floppy for muLinux to add a healthy mix of application programs
written in Tcl/Tk.  Requires the muLinux X11 add-on, as most Tcl programs
included are X11 based.

muLinux resources: 
	home page:
	mailing list:


Little documentation for each application is included.  Some applications have
builtin help;  check my 'notes' section for each entry.   Please refer to
the applications' URL's for additional documentation.

Preference files/directories:
Many application also want to save user preferences into various directories
under $HOME or $USER.  Typically, user files are stored as ".files" or 
".directories" under "/" or "/root", if running muLinux as a single user.

If you wish to save the applications' preferences, you should make your own 
arrangements to save and restore these files during muLinux startup and 

Licenses issues:  
The majority of the applications included have been written by others, and
are distributed under various license and/or copyrights.  
For GPLed applications, refer to
For BSD & copyrighted applications, see the license & copyright statement in 
each application.

    description: Tcl/Tk, tclsh & wish interpreters
    ver: 8.0.5
    license: BSD style
    author: John Ousterhout,
    tsp hacks:
	add proc 'source' to init.tcl: examine file name, if a file
	matches *.gz, then use gunzip to unpack source file.
	tk.tcl - make mulinux friendly defaults, background color, fonts

	gzip all tcl/tk library .tcl files, except init.tcl and tk.tcl

	most files in ./bin link to STARTUP.SH, which starts wish and
	causes the real program to be sourced from ../lib/bingz

	compiled under Redhat 4.2 (libc5)
	configure --prefix=/usr/tcltk --enable-shared --disable-symbols
	edit makefile to add '-Wl,-rpath,/usr/tcltk/lib' and
	'-Wl,-rpath-link,/usr/tcltk/lib' when linking shared libs & executables

	strip tclsh wish

    tsp hacks:
	added exec lines; use TCLTEXTEDIT_LIB for library directory;
	copy lib macro files when making $HOME/.tcltextedit/;

	for some reason, edit main program doesn't like most lib .tcl files
	to be compressed (?? !!) instead, put all but cfg.tcl inline in 
	main 'edit' source file.
	looks like you should be able to open an http:// url on the
	comand line, but doesn't seem to work.

	I haven't been able to contact him.
