This file is cgi.tcl/README. It contains brief descriptions of the
examples in this directory. You are welcome to send me additional
scripts.
--------------------
Instructions on running scripts
--------------------
The "examples.cgi" script provides a page of clickable links to all
the other example scripts. "frame.cgi" is a framed version - it's not
particularly good looking but it does work and - anyway - I needed a
frame example!
There are three ways of running these scripts:
1) Point your browser at http://expect.nist.gov/cgi.tcl
2) Run them by hand, such as by typing "tclsh scriptname" at the
command line. This is appropriate if you just want to study the raw
HTML output or see how fast they run.
3) Install them in your own web and run them through your browser.
(If you're on a UNIX host, the "make examples" target in the Makefile
fixes up the #! line of each examples and installs them in a public
demo directory.) You'll want to edit the example.tcl file to redefine
cgi_root appropriately.
If you run the examples locally (options 2 and 3):
- In order to get the submit buttons to take you back to your
site (instead of on to my site!), check the cgi_root call in
example.tcl to point back to your site.
- Some of these examples may do things that are not portable
and therefore may not run on all systems. For example, some
of them call "exec". The "unimail" script assumes the
existence of sendmail through cgi.tcl's built-in mail
support. See the ../install.win file for more info.
--------------------
Source files in this directory
--------------------
cookie.cgi - demonstrates cookies
display.cgi - display a CGI script
error.cgi - demonstrates error handing
examples.cgi - Provides a page with clickable links to all
these examples.
form-tour.cgi - demonstrates most form elements (Note that these
don't do anything - they're just for looks.)
format-tour.cgi - demonstrates many formats, unrelated to forms
frame.cgi - a friend's home page that demonstrates frames
kill.cgi - kill runaway CGI processes
parray.cgi - displays an array (or the environment by default)
passwd-form.cgi - creates a form for changing a password
passwd.cgi - backend to passwd-form where password is actually changed
Note that this script is an Expect script.
passwd.tcl - common definitions for passwd*.cgi scripts
upload.cgi - file upload
vclock.pl - Lincoln Stein's virtual clock from CGI.pm paper
vclock.cgi - Lincoln Stein's virtual clock (but in Tcl)
