/** |

|
|
* AlterOptionsCommandEvent is a subscriber to the Command Event |
|
13
|
|
|
* that looks up any additional options (e.g. from an OPTION_HOOK) |
|
14
|
|
|
* that should be added to the command. Options need to be added |
|
15
|
|
|
* in two circumstances: |
|
16
|
|
|
* |
|
17
|
|
|
* 1. When 'help' for the command is called, so that the additional |
|
18
|
|
|
* command options may be listed in the command description. |
|
19
|
|
|
* |
|
20
|
|
|
* 2. When the command itself is called, so that option validation |
|
21
|
|
|
* may be done. |
|
22
|
|
|
* |
|
23
|
|
|
* We defer the addition of options until these times so that we |
|
24
|
|
|
* do not invoke the option hooks for every command on every run |
|
25
|
|
|
* of the program, and so that we do not need to defer the addition |
|
26
|
|
|
* of all of the application hooks until after all of the application |
|
27
|
|
|
* commands have been added. (Hooks may appear in the same command files |
|
28
|
|
|
* as command implementations; applications may support command file |
|
29
|
|
|
* plug-ins, and hooks may add options to commands defined in other |
|
30
|
|
|
* commandfiles.) |
