| 22 <h1>eric6.DebugClients.Python.FlexCompleter</h1> | |
| 23 <p> | |
| 24 Word completion for the eric6 shell. | |
| 25 </p><p> | |
| 26 <h4>NOTE for eric6 variant</h4> | |
| 27 </p><p> | |
| 28 This version is a re-implementation of rlcompleter | |
| 29 as found in the Python3 library. It is modified to work with the eric6 | |
| 30 debug clients. | |
| 31 </p><p> | |
| 32 <h4>Original rlcompleter documentation</h4> | |
| 33 </p><p> | |
| 34 This requires the latest extension to the readline module. The completer | |
| 35 completes keywords, built-ins and globals in a selectable namespace (which | |
| 36 defaults to __main__); when completing NAME.NAME..., it evaluates (!) the | |
| 37 expression up to the last dot and completes its attributes. | |
| 38 </p><p> | |
| 39 It's very cool to do "import sys" type "sys.", hit the | |
| 40 completion key (twice), and see the list of names defined by the | |
| 41 sys module! | |
| 42 </p><p> | |
| 43 Tip: to use the tab key as the completion key, call | |
| 44 </p><p> | |
| 45 readline.parse_and_bind("tab: complete") | |
| 46 </p><p> | |
| 47 <b>Notes</b>: | |
| 48 <ul> | |
| 49 <li> | |
| 50 Exceptions raised by the completer function are *ignored* (and | |
| 51 generally cause the completion to fail). This is a feature -- since | |
| 52 readline sets the tty device in raw (or cbreak) mode, printing a | |
| 53 traceback wouldn't work well without some complicated hoopla to save, | |
| 54 reset and restore the tty state. | |
| 55 </li> | |
| 56 <li> | |
| 57 The evaluation of the NAME.NAME... form may cause arbitrary | |
| 58 application defined code to be executed if an object with a | |
| 59 __getattr__ hook is found. Since it is the responsibility of the | |
| 60 application (or the user) to enable this feature, I consider this an | |
| 61 acceptable risk. More complicated expressions (e.g. function calls or | |
| 62 indexing operations) are *not* evaluated. | |
| 63 </li> | |
| 64 <li> | |
| 65 When the original stdin is not a tty device, GNU readline is never | |
| 66 used, and this module (and the readline module) are silently inactive. | |
| 67 </li> | |
| 68 </ul> | |

| 129 <b>Completer</b>(<i>namespace=None</i>) | |
| 130 <p> | |
| 131 Constructor | |
| 132 </p><p> | |
| 133 Completer([namespace]) -> completer instance. | |
| 134 </p><p> | |
| 135 If unspecified, the default namespace where completions are performed | |
| 136 is __main__ (technically, __main__.__dict__). Namespaces should be | |
| 137 given as dictionaries. | |
| 138 </p><p> | |
| 139 Completer instances should be used as the completion mechanism of | |
| 140 readline via the set_completer() call: | |
| 141 </p><p> | |
| 142 readline.set_completer(Completer(my_namespace).complete) | |
| 143 </p><dl> | |
| 144 <dt><i>namespace</i></dt> | |

| 177 </p><p> | |
| 178 Assuming the text is of the form NAME.NAME....[NAME], and is | |
| 179 evaluatable in self.namespace, it will be evaluated and its attributes | |
| 180 (as revealed by dir()) are used as possible completions. (For class | |
| 181 instances, class members are are also considered.) | |
| 182 </p><p> | |

| 184 with a __getattr__ hook is evaluated. | |
