[CAU] 25-Nov-2005: I finally got around to putting this page together.  Something I've been meaning to do for at least 6 months.

THP is a way of embedding Tcl into HTML.

The requirements were quite straight forward.  Some features are fairly obvious, others less so:
    * PHP, ASP and the like all allow the web developer to embed code directly into the markup language.  I wanted to be able this with my preferred scripting language - Tcl.
    * I wanted to ensure that only complete commands were executed so simply using eval was out.
    * I wanted to be able to embed bits of HTML inside the code directly such as
 <%tcl while {$i<10} { %><B>Repeated line</B><BR><%tcl } %>
    * I wanted to be able to include other files by preparsing them (or pre-interpreting).
    * I wished to make the code as neat and fast as I could without making it unreadable (not sure if I've achieved either, you be the judge).
    * The code should be platform, server and client independent.
    * Using THP must be very easy.


Why THP?  Well, it's a play on the PHP name - ''(T)cl (H)ypertext (P)reprocessor''


I've been using THP now for a little while, tweaking where necessary, and think that it generally fits what it was supposed to do.

THP has been tested on:
    * Linux with Apache using both the standard interpreter (tclsh) and tclkit.
    * Windows XP/Server2003 with Tclhttpd using and IIS using tclsh and tclkit.
    * Windows XP/Server2003 with IIS and THP wrapped as a starpack.

I had some fun putting the starpack version together and figuring out IIS for the first time.  Getting THP working with Tclhttpd outside of the cgi-bin directory was a challenge too, but it works a treat!
