[I should make a point of explaining clearly that there are several distinct approaches to CGI coding with Tcl, including:
- cgi.tcl (see cgi.tcl extension)
- JM Ivler's book BOOK CGI Developer's Resource - Web Programming in Tcl and Perl
- "by hand", described in "Writing simple CGI applications using vanilla Tcl" and "Using Tcl to write CGI applications"
- "Wikit under CGI"
- cgilib.tcl from Brent Welch's BOOK Practical Programming in Tcl and Tk, Third edition. ncgi is descended from and largely supersedes cgilib.
- websh can be used in CGI mode for Apache 1.3 and 2.0
- cgi by hand
- Playing CGI
- FastCGI is also likely to be of interest.
To the extent that CGI is used in the casual sense of "dynamically generated web pages, or forms handling, or Web application", there is also AOLServer, with its built-in TCL interpreter and database hooks, and nstcl, which is a TCL-only extension which has AOLServer's API to http queries and database handling, as well as a templating library.As is Apache Tcl and Rivet.Tclhttpd supports dynamically generated content, and also optionally implements the vanilla CGI API as one of its Tclhttpd Domains.
