| 315 | 1 ========================================= |
| 2 Features requiring only parameter changes | |
| 3 ========================================= | |
| 4 | |
| 324 | 5 Several aspects of a ``cmd2`` application's behavior |
| 6 can be controlled simply by setting attributes of ``App``. | |
| 7 | |
| 328 | 8 (To define your own user-settable parameters, see :ref:`parameters`) |
| 315 | 9 |
| 10 Case-insensitivity | |
| 11 ================== | |
| 12 | |
| 324 | 13 By default, all ``cmd2`` command names are case-insensitive; |
| 14 ``sing the blues`` and ``SiNg the blues`` are equivalent. To change this, | |
| 15 set ``App.case_insensitive`` to False. | |
| 16 | |
| 17 Whether or not you set ``case_insensitive``, *please do not* define | |
| 18 command method names with any uppercase letters. ``cmd2`` will probably | |
| 19 do something evil if you do. | |
| 20 | |
| 21 Multiline commands | |
| 22 ================== | |
| 23 | |
| 24 Like cmd_, ``cmd2`` assumes that a line break ends any command. | |
| 25 However, ``App.multilineCommands`` is a list of commands that are assumed to span | |
| 26 multiple lines. For these commands | |
| 27 | |
| 28 ``cmd2.Cmd.multilineCommands`` defaults to [], so you may set your own list | |
| 29 of multiline command names (without ``do_``):: | |
| 30 | |
| 31 class App(Cmd): | |
| 32 multilineCommands = ['lenghtycommand'] | |
| 33 def do_lengthycommand(self, args): | |

| 36 Shortcuts | |
| 37 ========= | |
| 38 | |
| 39 Special-character shortcuts for common commands can make life more convenient for your | |
| 40 users. Shortcuts are used without a space separating them from their arguments, | |
| 41 like ``!ls``. By default, the following shortcuts are defined: | |
| 42 | |
| 43 ``?`` | |
| 44 help | |
| 45 | |
| 46 ``!`` | |
| 47 shell: run as OS-level command | |
| 48 | |
| 49 ``@`` | |
| 50 load script file | |
| 51 | |
| 52 ``@@`` | |
| 53 load script file; filename is relative to current script location | |
| 54 | |
| 55 To define more shortcuts, update the dict ``App.shortcuts`` with the | |
| 56 {'shortcut': 'command_name'} (omit ``do_``):: | |
| 57 | |
| 58 class App(Cmd2): | |
| 59 Cmd2.shortcuts.update({'*': 'sneeze', '~': 'squirm'}) | |
| 60 | |
| 61 Timing | |
| 62 ====== | |
| 63 | |
| 64 Setting ``App.timing`` to ``True`` outputs timing data after | |
| 65 every application command is executed. |settable| | |
| 66 | |
| 67 Debug | |
| 68 ===== | |
| 69 | |
| 70 Setting ``App.debug`` to ``True`` will produce detailed error stacks | |
| 71 whenever the application generates an error. |settable| | |
| 72 | |
| 73 .. |settable| replace:: The user can ``set`` this parameter | |
| 74 during application execution. | |
| 75 (See :ref:`parameters`) | |
| 76 | |
| 77 .. _quiet: | |
| 78 | |
| 79 Quiet | |
| 80 ===== | |
| 81 | |
| 82 Controls whether ``self.pfeedback('message')`` output is suppressed; | |
| 83 useful for non-essential feedback that the user may not always want | |
| 84 to read. Only relevant if :ref:`outputters` are used. | |
| 85 | |
| 86 Settability | |
| 87 =========== | |
| 88 | |
| 89 If you wish the user to be able to set one of these | |
| 90 application-controlling attributes while the application | |
| 91 is running, add its name to ``App.settable``. See | |
| 92 :ref:`parameters`. | |
