Wapp - A Web-Application Framework for TCL

Wapp is a new framework for writing web applications in TCL, with the following advantages:

Very small API → easy to learn and use
A complete application is contained in a single file
Resistant to attacks and exploits
Cross-platform → CGI, SCGI, or a built-in web server
The MVC design pattern is supported but not required
The Wapp framework itself is a single-file TCL script that is "source"-ed, "package require"-ed, or even copy/pasted into the application TCL script
2-clause BSD license

Here is a minimal web application written using Wapp:

#!/usr/bin/tclsh
package require wapp
proc wapp-default {} {
  wapp-subst {<h1>Hello, World!</h1>\n}
}
wapp-start $argv

To run this application using the built-in web-server, store the code above in a file (here we use the name "hello.tcl") and do:

tclsh hello.tcl

To run the app using the built-in web-server bound to all TCP addresses and listening on port 8080, use:

tclsh hello.tcl --server 8080

To run the app as an SCGI server listening on port 9001:

tclsh hello.tcl --scgi 9001

To run the application as CGI, make the hello.tcl file executable and move it into the appropriate directory of the web server.
