Texis Web Script (Vortex) is an HTML-based, server-side scripting
language that makes creating, deploying and maintaining Web-based
applications easy. It combines into one package four of the most
The fundamental idea behind Vortex is to extend HTML with
programming capabilities which are directed towards the most
commonly performed Web activities. This extended HTML language is
called Vortex. HTML was chosen as a base language because it is
widely known and conducive to scripting. It also makes output and
script code easily intermixable.
- Texis: An object enabled SQL RDBMS
- Metamorph: Concept-based text retrieval
- Vortex: A CGI scripting language and compiler
- Texis Web Server: A fast web server with integrated Vortex
Vortex scripts reside in HTML files on a Web server, and are run
by the CGI program texis
on the server upon request of a Web
browser. The location of the script is derived from the relative
path given in the URL, which is translated to a path in the HTML
document tree. It may also be given on the command line if texis
is run directly.
Since Vortex is a server-side language, users do not need a
particular browser version to utilize a Vortex application, nor
download and install a helper app or plugin. Also, because script
paths are derived from the URL, no additional configuration or
directories are needed to install them.
When a script is run, texis
compiles it into an object
file, with a .vtx
file extension, which is then executed.
This enables a Vortex script to run much faster than if it were
interpreted every run, such as a Unix shell script or Perl.
Compilation is completely transparent to the user, and happens
instantly and automatically only when needed.
While Vortex scripts will run on any web server that supports
CGI, by replacing the web server/CGI texis
the Texis Web Server (vhttpd
applications can gain additional speed. The Texis Web Server is
more "streamlined" than most, and Vortex is built-in. This enables
Vortex scripts to start 20% faster than in a typical web server/CGI
environment. However, the real advantage to vhttpd
from its smaller resource footprint. Less process slots and memory
are used per transaction than other servers. This frees resources
to support more hits per second on the same platform.
supports entry and exit scripts.
A Vortex script can be configured to run at the start and end
of every transaction on the server, even for non-Vortex hits like
file transfers. These can be used to establish look-and-feel,
security, and logging functions across an entire web site,
maintained in one place.
