| 38 | Thanksalot for this! |

| 40 | Yesterday I tried to mungle some of already | 
| 41 | existing code from org.netfrag.flib towards | 
| 42 | your proposal - what came out was: | 
| 43 |  | 
| 44 |  | 
| 45 | --- The php and the Exporter classes. | 
| 46 |  | 
| 47 | syntaxing inspired by bareface: (e.g.) | 
| 48 |  | 
| 49 | php::useNamespace("Data::Driver"); | 
| 50 | $config = php::getInstance("Proxy"); | 
| 51 |  |

| 57 | What did we do? | 
| 58 |  | 
| 59 | We tried to refactor some code to a newly | 
| 60 | introduced class named 'php': |

| 71 |  | 
| 72 | What did we have? | 
| 73 |  | 
| 74 | Some code living at org.netfrag.flib: | 
| 75 |  | 
| 76 | @package org.netfrag.flib | 
| 77 | @file flib/utils/helper.php | 
| 78 | @file flib/utils/shortcuts.php |

| 82 | Some code living at org.netfrag.glib: |

| 84 | @package org.netfrag.glib | 
| 85 | @subpackage DesignPattern | 
| 86 | @file ...rag.glib/DesignPattern/Bridge.php |

| 99 | What do we have *now*? | 
| 100 |  | 
| 101 | Some code living at org.netfrag.glib: | 
| 102 |  | 
| 103 | @file ...rag.glib/php_extensions.php | 
| 104 | @component php_extensions | 
| 105 | @class php | 
| 106 | @methods loadModule, mkInstance, mkComponent | 
| 107 |  | 
| 108 | @file ...rag.glib/Exporter.php | 
| 109 | @component Exporter | 
| 110 | @class Exporter | 
| 111 |  | 
| 112 | The Exporter is used to alias php::mkComponent | 
| 113 | to the former global function mkObject. | 
| 114 |  | 
| 115 | @subsequence | 
| 116 | @synopsis The classes can be used this way: | 
| 117 |  | 
| 118 | <code> | 
| 119 |  | 
| 120 | php::loadModule('my::Module'); | 
| 121 |  | 
| 122 | $comp = php::mkComponent('my::Module'); | 
| 123 |  | 
| 124 | $obj = php::mkInstance('my_Class'); | 
| 125 |  | 
| 126 | </code> | 
| 127 |  | 
| 128 |  | 
| 129 | Of course, additional arguments can be fed | 
| 130 | to the constructors in case of object- | 
| 131 | instantiation (mkComponent and mkInstance). | 
| 132 | Just pass them as additional arguments... | 
| 133 |  | 
| 134 | <code> | 
| 135 |  | 
| 136 | $comp = php::mkComponent('my::Module', array( opt1 = >'hello' ), 'arg2' ); | 
| 137 |  | 
| 138 | </code> | 
| 139 |  | 
| 140 | greets, joko. | 
| 141 |  | 
| 142 |  | 
| 143 | p.s.: | 
| 144 | To actually implement your proposal one-by-one: | 
| 145 |  | 
| 146 | Using the Exporter, it should be quite easy | 
| 147 | to alias php::mkComponent to php::getInstance. | 
| 148 | Adding your proposed php::useNamespace, the | 
| 149 | missing functionality (provided by php::getInstance) | 
| 150 | would be added as a fallback mechanism at | 
| 151 | the top of php::mkComponent: | 
| 152 | + prefix modulename with namespace if desired (set by 'useNamespace') | 
| 153 |  | 
| 154 | Here is the glitch: We actually have two *different* | 
| 155 | types of namespaces following this proposed component | 
| 156 | architecture: | 
| 157 | - ClassNamespace | 
| 158 | - ModuleNamespace | 
| 159 |  | 
| 160 |  | 
| 161 | [...] again - the post scriptum became way too long, | 
| 162 | so got refactored to a seperate document posted elsewhere - | 
| 163 | a reference will be added later.... | 
| 164 | The title will be: "DummyNamespaces in PHP - final proposal" [...] |
