[REBOL] [ANN] working example - standard message function library
From: norsepower::uswest::net at: 8-Feb-2001 14:24
The Standard Message Function Library has been updated at http://
www.dangeroustechnology.com/standard-message-function-library.txt
The Standard Message Dialect uses the library plus two short .cgi scripts
(create-message.cgi and display-messages.cgi), a configuration-file.r and a
cascading stylesheet to run an entire news site. The two .cgi scripts handle
the input/output of message creation for all types of messages, including
news, comments, classified, forums, etc.
--------------------
To create a message, you pass author, subject, content, and messageType
variables to create-message.cgi. Following is create-message.cgi:
#!rebol -cs
REBOL []
do load %standard-message-function-library.r
cgi-input: retrieve-user-data
create-message/from-cgi cgi-input
--------------------
To display messages, you pass messageType and messageID variables to display-
messages.cgi. Following is display-messages.cgi:
#!rebol -cs
REBOL []
do load %standard-message-function-library.r
cgi-input: retrieve-user-data
do load %configuration-file.r
stylesheet: read %stylesheet.html
print "Content-Type: text/html^/"
print html-page-header
print stylesheet
print pre-messages
display-messages cgi-input
print post-messages
--------------------
That's it.
All messages are saved as XML and displayed as CSS-HTML.
To view a working example, go to http://test.fargonews.com It's a little bit
ugly because of the short, redundant messages, but you get the concept. When
you visit http://test.fargonews.com, REBOL executes an index.cgi script which
simply passes messageType and messageID variables to display-messages.cgi.
The site can further be expanded by creating directories of message data in
XML for /classified , /comments , etc. The type of messages displayed depends
on messageType. A separate stylesheet can be called for separate messageType
variables.
You can display a specific message by sending a valid messageID instead of
none
to the script.
You can view a message creation form by logging in using username1 and
password1 at http://test.fargonews.com/login.html
Your login is verified and encrypted using REBOL (thanks to %encrypt.r by
Bohdan Lechnowsky) and you are taken to a message creation form (built
dynamically upon login validation.) After you submit your message, it will
appear at the bottom of the page at http://test.fargonews.com
As always, your input is appreciated.
