Lambda

This module lets you create a module without writing PHP code.

Warning: this module requires PHP 5.2!

Based on the aspect oriented nature of Drupal, it adds functional/declarative way with strict typing to create modules.

Advantages of the declarative programming and strict typing:

• easy testing
• more secure
• less bugs (bugs based on type errors are not possible [eg.: you get null or false instead of something])
• every single bit is reusable

Features:

• easy integration (all you have to do is to write some 10-lines-long classes)
• easy exporting (patterns, bones etc), since the modules itself can be stored in XML, YAML or any other format (CSV, tabulated txt, RDF, OWL)
• "code" "runs" in a managed context

The lambda_builder GUI will be made in Flex.

This module is under heavy development.
Development note: with D7 code freeze, the 6.x development branch will be suspended.

Testing instructions

• Set error reporting to E_ALL | E_STRICT in php.ini
• Or set php_value error_reporting 8191 in .htaccess

(this number is tested on PHP 5.2, it may vary depending on your PHP version; you can check it by typing print E_ALL|E_STRICT to the php interpreter, invoked by php -a)

• If you have a other modules installed, and you get a lot of E_STRICT warnings about static function calls (which is valid in PHP 4), you might want to set error reporting to E_ALL (6143).
• Install xdebug
• If you have devel installed, set error handler to "None"

Extra requirements for modules

• all: SPL (normally part of PHP)
• lambda_xml: SimpleXML (normally part of the PHP)
