Gambas Server Pages

In Gambas, you have some sort of scripter hack that allows you to write ASP-like files that I named " server pages".

Put that in a text file, make it executable, and run it.

#!/usr/bin/env gbw3
DIM sEnv AS String

<!-- Variable declaration must come before any HTML -->


<h2>CGI script environmental variables</h2>

<table border="1" cellspacing="0" cellpadding="2">

    <th align="left">Name</th>
    <th align="left">Value</th>

<% FOR EACH sEnv IN Application.Env %>
  <tr valign="top">
    <td><%= sEnv %></td>
    <td><%= Application.Env[sEnv] %>&nbsp;</td>
<% NEXT %>



As you can see, the server page is a script, but the script executable is 'gbw3', not 'gbs3'.

'gbw3' is actually a symbolic link to 'gbs3'. When 'gbs3' detects than it is run from the 'gbw3' symbolic link, it knows that it will have to process a server page and not a script. Then 'gbs3' will transform the server page into...a normal script, and will execute it.

Except the initial line with the '#!/usr/bin/env gbw3' magic, the syntax is very similar to ASP pages.

  • <% XXX %> introduces any Gambas code.

  • <%= XXX %> evaluates a Gambas expression, translates it into HTML, and inserts the html inline.

Note that the gb.web component is used by default. So you can use the Session object, the Response object, the Request object, and so on.

These Gambas server pages are CGI scripts, and must be managed as any other script in your preferred web server.

This feature is experimental. Please report any problem you could have with it!

Using extra components

To use other components, server pages implement a special instruction named USE:

USE "_component name_"

That instruction loads a component as when it is checked in the component tab of the project properties dialog in the IDE.

Note that the component name must be specified as a string, i.e. between quotes.
