For each cycle

[jekko1976]

Wouldn't be cool to add the for each cycle, like php, to our beloved autohotkey?

Bye

[swagfag]

what do u mean? there is a for each already

[jekko1976]

i'm not sure about that
For sure there are almost 35 way different to obtain a Foreach cycle but, AFAIK the literal Foreach doesn't exist.

Code: Select all

Array := []
Array[1] :=how
Array[2] :=are
Array[3] :=you
For each element in Array
	{
		MsgBox, element
	}

this code does not compile.

Anyway it's not necessary, of course. It could be useful for who came by php, nothing more.

Google told me that the case has been discussed many years ago

Code: Select all

Array := []
Array[1] :=how
Array[2] :=are
Array[3] :=you
For each, element in Array
	{
		MsgBox % element
	}

[just me]

Code: Select all

Array := []
Array[1] := "how" ; if it shall be a literal string
Array[2] := "are"
Array[3] := "you"
For each, element in Array
	{
		MsgBox %element% ; if it shall be a variable reference
	}

ah, with the comma it works.
Ok, thank you very much

realize its just a trick, the syntax is for key,val in object, you are just giving the 'key' variable the name 'each' since you don't care about the 1,2,3 indexes in your array. you can name them whatever you want

Code: Select all

Array := []
Array[1] := "how"
Array[2] := "are"
Array[3] := "you"
For each, element in Array
	{
		MsgBox %each% : %element%
	}

Code: Select all

Array := []
Array[1] := "how"
Array[2] := "are"
Array[3] := "you"
For foo, bar in Array
	{
		MsgBox %foo% : %bar%
	}
