Code Generation in Perl

[prev] [thread] [next] [Date index for 2004/06/15]

Some time ago, I sent a message to the list, talking about this open 
source application:

http://www.gnubis.com.br/cgi-local/crm/bin/crm.pl?template=pg_sel_contact

What I didn't tell you at the time, is that I've been working on a code 
generation tool to generate a database-driven web application, like 
this, in minutes.

First, you describe your application using a XML dialect called "AppML" 
("Application Markup Language"):

<project name="sample" title="Sample Application">

   <table name="contact" caption="contact" descriptor="name">
     <field name="name" type="varchar" size="40" notnull="1" 
caption="name"/>
     <field name="organization" type="varchar" size="40" 
caption="organization" visible="1"/>
     <field name="address" type="varchar" size="40" caption="address"/>
     <field name="city" type="varchar" size="40" caption="city"/>
     <field name="state" type="varchar" size="40" caption="state"/>
     <field name="country" type="varchar" size="40" caption="country"/>
     <field name="phone" type="varchar" size="40" caption="work phone"/>
     <field name="fax" type="varchar" size="40" caption="fax"/>
     <field name="mobile" type="varchar" size="40" caption="mobile"/>
     <field name="email" type="varchar" size="40" caption="e-mail" 
visible="1"/>
     <field name="notes" type="text" caption="notes"/>
   </table>

</project>

That's it!

Given the XML file, a Perl script will generate the complete Perl code, 
Class::DBI modules, templates, plugins, documentation and diagrams 
automatically.

I'm releasing AppML under the GNU General Public License. The complete 
source code is available here:

Any feedback will be appreciated!

Best wishes,

Nelson
