5.8.9. Instruction plugins

Instructions can be packed as plugins, however, they need a more sophisticated format. Open Power Template requires the instruction plugins to:

The file name must be in the format: instruction.Foo.php
The class name must be in the format: Opt_Instruction_Foo, where Foo must be the same, as in the file name.

A sample instruction plugin can be found below:

<?php
// instruction.Plugin.php
 
class Opt_Instruction_Plugin extends Opt_Compiler_Processor
{
    // ...
} // end Opt_Instruction_Plugin;

Note that you can also register the instruction manually:

$tpl->register(Opt_Class::OPT_INSTRUCTION, 'Foo');  // Registers "Opt_Instruction_Foo"
$tpl->register(Opt_Class::OPT_INSTRUCTION, 'Foo', 'Some_Class'); // Registers "Foo" in the "Some_Class" class

In this case, the class name does not have to begin with Opt_Instruction. The second line shows, how to register such classes in OPT.
