This file is install.mac. It contains installation instructions for
cgi.tcl on MacOS.
If you do not have Tcl, get it (the README explains how) and install
it. The rest of these instructions assume that you have Tcl
installed.
--------------------
Installation
--------------------
These instructions are based on contributions courtesy of Henk-Jan
Kooiman <hjk@cable.a2000.nl>. Send fixes to me (libes@nist.gov).
If you just want to experiment with cgi.tcl, you can simply source it
into your Tcl files by saying "source cgi.tcl".
Once you're done playing, go ahead and install it. To install it:
1) Make a package index. (This will create pkgIndex.tcl which will
make it possible to use "package require cgi" in scripts.) Asari
Hirotsugu <asari@math.uiuc.edu> has supplied the following
elaboration of this step:
1a) Put the cgi.tcl folder in the "Tool Command Language" folder
inside the Extensions folder. (Don't make an alias for the Tool
Command Language folder since Tcl Shell doesn't resolve aliases as
of 8.2.1.)
1b) Launch the Tcl Shell (or Wish) and move to the Tool Command
Language folder by entering:
cd "Macintosh HD:System Folder:Extensions:Tool Command Language"
(You may have to modify this command depending upon the names
and structure of your file system.)
Issue the pkg_mkIndex command:
pkg_mkIndex cgi.tcl*
1c) Test if the package command works by trying:
package require cgi
2) You may want to edit some things in cgi.tcl at this time.
2a) Upon errors in production code, cgi.tcl sends mail to an
administrator. This can be set on a per-script basis but it
defaults to "root". You'll probably want to change this for your
site. To do that, search cgi.tcl for cgi_admin_mail_addr "root" and
change the argument to whatever you prefer.
2b) The cgi_mail_end procedure attempts to do mail delivery using
SMTP (the de facto Internet mail protocol). However, this mechanism
is not robust. For example, if the mail gateway is down, the mail
will not be requeued for later delivery. If you have a robust
mailer program or some other interface, you should switch to using
it. The ability to send mail isn't required for basic use of
cgi.tcl, but this ability is especially useful for in-the-field
debugging so I encourage you to use it.
You're done! Now you can use cgi.tcl.
