The current implementation of MetaL compiler engine and the available modules were developed with about 20.000 lines of PHP code. PHP is a scripting language that was originally meant for Web programming. It may seem odd to the use PHP for a heavy task such as compiling source files. Today PHP is not such a slow language, thanks to the Zend compiler and optimizer. The MetaL compiler engine also makes extensive use of caching of previously parsed XML files. |
