- tclshar
-
An extremely rudimentary version of shar, the unix
shell archive maker, which works with tclsh. A tclshar
is a tcl program which when executed extracts itself into the
current directory and recreates the directories and files it
archives. This is the obvious way to distribute pure tcl
programs so they can be downloaded onto windows and macs as
well as unix systems.
An updated tclshar now produces archives which behave somewhat reasonably when executed by wish, as might happen if one was double clicked on Windoze.
- good-time
- A tcl script which fetches the correct time via telnet from
time.nist.gov and prints it out in standard format. Several
other time sources on the internet and their formats are also
documented in the script.
- mankala
- An ancient game of stones in pits programmed in Tcl/Tk. Play with
your friends, play against the computer, or just let the computer
play against itself.
- subtile 0.2
-
A Tcl/Tk (4.0 or 4.1) program for generating Penrose, Ammann,
and other aperiodic tilings through substitution or composition
rules, displaying them, taking their fourier transforms, and
generating postscript you can print for the kids to color.
- subtile 0.3
-
A Tcl/Tk (8.0 or greater) program for generating Penrose, Ammann,
and other aperiodic tilings through substitution or composition
rules, displaying them, taking their fourier transforms, and
generating postscript you can print for the kids to color.
Now packaged with tclshar so it can be unpacked onto the Mac or Windows and using the file pathname constructors so it should run there, too.
Inspired by Marjorie Senechal's Quasicrystals and Geometry (Cambridge UP, Cambridge, 1995), with support from Branko Grünbaum and G. C. Shephard, Tilings and Patterns, (WH Freeman, New York, 1987).
- maze
- The maze screensaver from
xlockmore
converted to a Tk program so you can amuse yourself and your
small children by solving the maze instead of pretending to be
a potato while your computer does it. Or you can push the
solve button and be an interactive potato.
- palette.tcl
- A reworking of Eric Grosse's
rainbow
color palette generator from
netlib.
This allows you to generate a variety of color
palettes in Tcl. I happen to like the "iron" palette
which looks like a black body temperature scale.
A version old-palette.tcl for the namespace challenged.
- random.tcl
-
George Marsaglia's mother of all random number generators,
written in Tcl. This is a very long period pseudorandom number
generator.
A version old-random.tcl without namespaces.
- time.tcl
- A collection of time and date computations written in Tcl.
This solves the problem of converting Unix julian time (seconds since
January 1, 1970 0h UT) into calendar date in Tcl-7.4 and earlier.
Note that the difference between the year 95 and the year 1995 is 19 centuries, and though you may have a vested interest in the current century, the algorithm does not.
- xpm-to-image.tcl
-
A Tcl procedure for converting xpm format pixmaps into Tk photo images.
