For-Loop Remove Index and replace with Built In Variables

[Delta Pythagorean]

I think it's kind of redundant to have the Value and Key parameter in the command when AHK has built in variables for it anyway.
For example, instead of the syntax being like this:

Code: Select all

For Key [, Value] in Expression
{
	; Some Actions
}

Why not have the syntax like this:

Code: Select all

For (Array,Obj, or Expression) {
	MsgBox, % A_LoopFieldName " = " A_LoopField
}

I don't know, something along those lines. And maybe for backward comp, keep the old syntax available for use.

Ok I am too tired to code. I meant to use variables that are built into AHK, and use them for a "better" syntax of a For-Loop

Actually, you could make the opposite argument. To allow the Loop control flow statement to support custom variable names instead of A_Index and A_LoopField, or A_LoopFileFullPath.

The benefit would be that you could use the same variable names that you use in normal circumstances, both inside and outside of loops.

Anyhow as it is now, lines where you simply copy the variable contents over:
vTemp := A_LoopField
vPath := A_LoopFileFullPath
are not so bad.

The fact that the object loop allows custom variable names is a great advantage.

[EDIT:] However, if this were possible, to allow the use of certain 'A_' variables, that could make certain code reuse easier. Not that I would personally want to do this, or think it necessarily worth the cost of implementation.

Code: Select all

for A_Index, A_LoopField in oArray
	vOutput .= A_Index " " A_LoopField "`r`n"
