Enumeration

[MattHiggs]

Hey all.  So I am embarrassed to admit this, but the desire to understand is suppressing that, but, in the years that I have been teaching myself other languages and other IT-related principles, the word "enumeration" comes up quite a lot.  Now I understand what that means when used in a mathematical context, but in scripting/IT context, seems to have different meanings depending on where it is applied, whether it is an adjective or a verb, etc.  Does someone want to take a shot at explaining the concept of enumeration as it relates to IT/scripting, or just link me to a resource that does so?  At this point, when I see the phrase "enumerate a registry key" or "returns an enumerated object", I have no freaking clue what any of that means

It means to "list" things... For example: "Enumerate a registry" means to list that registry

Ok, so lets take the registry key example then.  I am guessing that if there were a function which enumerated a registry key, that would return, in some kind of format, a list of the indicated key's sub-keys, the values present in each, and their values, or something similar?

[TheDcoder]

Yup, that would be it... You can say that: Registry Editor enumerates the values of a registry key:

I use Enums to create meaningful variable names for array indexes.

; Binding GUI Control names, the deletes are buttons
Enum    $eCC_GUI_binding_control_index_label, _
        $eCC_GUI_binding_control_action_delete, _
        $eCC_GUI_binding_control_action_edit_button, _
        $eCC_GUI_binding_control_action_combo, _
        $eCC_GUI_binding_control_action_internal_input, _
        $eCC_GUI_binding_control_event_icon_pic, _
        $eCC_GUI_binding_control_event_input, _
        $eCC_GUI_binding_control_event_released_combo, _
        $eCC_GUI_binding_control_event_delete, _
        $eCC_GUI_binding_control_event_keyboard_pic, _
        $eCC_GUI_binding_control_cooldown_input, _
        $eCC_GUI_binding_control_data_max
        
$aCC_GUI_binding_control[$i][$eCC_GUI_binding_control_action_delete] = GUICtrlCreateButton("x", $action_delete_button_pos_x, $i * $gCC_row_h, $action_delete_button_pos_w, 20)

A more simple version would be:

Enum $eCoord_x, $eCoord_y, $eCoord_z, $eCoord_max

Local $aCoord[9001][$eCoord_max]

$aCoord[$i][$eCoord_x] = 10

@Xandy I do not think that he is talking about "Enum" but about Enumeration in general .

Do you think the AutoIt keyword would be named Enum if it was something completely different?

[TheDcoder]

@water Huh? I did not say that it is different... I just pointed out that the OP is not asking about the Enum keyword.

[water]

Enum is AutoIt's keyword for an Enumeration. According to the help file: "Enum - Enumerates constants."
When the OP asks about Enumeration in an AutoIt forum then Enum is a valid answer.

[iamtheky]

and in the IT/scripting sense, the literal is the most apt.  It is a list of things, one by one.  And enum is even more literal in that it assigns numbers to those items, putting some numeration on your numeration.

@iamtheky you deserve remuneration for that enumeration elucidation

[jchd]

Yes, that's worth some money. Count with me: $1 or 2 or 3 or 4 or ...

I have no idea what it means, but it's the best bit of English I've read in a while: very poetic!
