OVERVIEW Embperl gives you the power to embed Perl code in your HTML documents. Using Perl means being able to use a very elaborate programming language, which is widely used for WWW purposes. You can also use hundreds of Perl modules which have already been written - including DBI - for database access to a growing number of database systems. While this could also be done with other packages, Embperl has several features especially for HTML: dynamic tables, formfield-processing, escaping/unescaping and more. Embperl is a server-side tool, which means it's browser-indpendent. It can run in various ways: Under mod_perl, as a cgi script, or offline. There is also a module for Database access within Embperl, look at DBIx::Recordset.

Perl code is evaluated at the server side and the result is sent to the browser. * Offers various meta-commands for conditional and loop processing of the HTML documents. * Automatically generates dynamic HTML tables/lists from Perl arrays or function calls (e.g. DBI fetch) * Form data send to your document is placed in a hash * Automatically inserts data from the form hash into HTML input, textarea and select tags * Understands HTML and URL escaping and unescaping * Handles per-user and per-module persistent session data for you. All you need to do is store and retrieve them to and from a special hash. * Allows you to build your web-site out of components. Frequently used elements can be defined once and included in every page. * Gives you the possibility to build libraries with a set of frequently used Elements or components, and make them available to the whole web-site in the same way as Perl modules are - well, modularized. * Supports debugging of pages by generating a very detailed log file and making it accessible via the browser with a single click. * Generates verbose error pages in which every error can link to the log file. This is ideal for debugging. * Offers a lot of options for maximum configurability according to your personal tastes and needs. * Fully integrated into Apache and mod_perl to acheive the best performance. Can also run as a CGI-script, offline or called from another Perl program. * The Perl module DBIx::Recordset offers high level, easy to handle database access for Embperl. * If you are concerned about security you can configure Embperl to use Safe.pm. This way, your documents can run in a safe namespace which can allow or disallow certain Perl opcodes.

Bugs, questions, suggestions for things you would find useful, etc., are discussed on the mod_perl mailing list. >From the mod_perl README: The Apache/Perl mailing list (modperl@apache.org) is available for mod_perl users and developers to share ideas, solve problems and discuss things related to mod_perl and the Apache::* (and Embperl) modules. To subscribe to this list, send mail to majordomo@apache.org with the string "subscribe modperl" in the body. There is a hypermail archive for this list available from: http://outside.organic.com/mail-archives/modperl/ There is an Epigone archive for the mod_perl mailing list at http://forum.swarthmore.edu/epigone/modperl COMMERICAL SUPPORT You can get free support on the mod_perl mailing list (see above). If you need commercial support, ecos can provide it for you. We offer: * Consulting and assitance for you and your programmers * Planning of your dynamic website * Creating of parts or a whole website * Fixing bugs in Embperl (also available for mod_perl) * Adding new features You can reach us via http://www.ecos.de or info@ecos.de AUTHOR G.
