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!
