README

InterfaceDistiller allows you to derive Interfaces from the API of a class.

Basic Usage Example

Interface Distiller can either be used a) programmatically, b) via a Builder or c) via the command line. Using it programmatically offers the greatest flexibility but is usually not needed. The Builder offers a convenient way to configure distillation of interfaces. The command line interface is a wrapper around the Builder and offers the same options.

Example 1 - Using the Builder

<?php
$distiller = new InterfaceDistiller;
$distiller
    ->methodsWithModifiers(\ReflectionMethod::IS_PUBLIC)
    ->extendInterfaceFrom('Iterator, SeekableIterator')
    ->excludeImplementedMethods()
    ->excludeInheritedMethods()
    ->excludeMagicMethods()
    ->excludeOldStyleConstructors()
    ->filterMethodsByPattern('(^get)')
    ->saveAs(new SplFileObject('MyInterface.php'))
    ->distill('SomeFoo', 'MyInterface');

With the notable exception of the distill and reset method, all other public methods provide a Fluent Interface. Calling distill will create a new interface from the specified class and given configuration. The source class is not altered in any way (it's not extraction). Subsequent calls to distill will use the same configuration unless reset was called.

Example 2 - Using the Commandline Interface

To use the Commandline Interface, you have to run build/create_phar.php to build a phar file previously.

    Usage: phpdistill [options] <classname> <interfacename>

      --bootstrap                           Path to File containing your bootstrap and autoloader

      --methodsWithModifiers <number>       A ReflectionMethod Visibility BitMask. Defaults to Public.
      --extendInterfaceFrom  <name,...>     Comma-separated list of Interfaces to extend.
      --excludeImplementedMethods           Will exclude all implemented methods.
      --excludeInheritedMethods             Will exclude all inherited methods.
      --excludeMagicMethods                 Will exclude all magic methods.
      --excludeOldStyleConstructors         Will exclude Legacy Constructors.
      --filterMethodsByPattern <pattern>    Only include methods matching PCRE pattern.
      --saveAs                              Filename to save new Interface to. STDOUT if omitted.

The CommandLine Interface requires you to set the pathname to your bootstrap file in the --bootstrap option. Your bootstrap file should contain all the necessary logic to include any classes you want derive interfaces from, e.g. autoloaders, include paths, etc. Without that you will only be able to distill from native classes.

If you installed InterfaceDistiller through the Composer package manager, the commandline tool will try to include the autoloader in the vendor directory.

The Commandline Interface will always reset configuration between calls. This means you need to specify the full configuration for each class you want to distill interfaces from.

Example 3 - Using the progammatic approach

A programmatic example can be found in the examples folder. In general, you will only need this approach if you need to add, modify or swap out internal components.
