How To Create A Multiline String From A Set Of Variables

[roonyrooxcess]

Hi, Im trying to create a multiline string, but not sure how to ...

Basically using a loop of someort to put the variables from A1=Apples A2=bananas A3=Oranges etc., into a multiline string, so it looks like this ...

Code: Select all

D=
(
Apples 
bananas 
Oranges
)

It needs to use a loop of somesort, as the script has a lot of data ...

Thanks.,

probably the most straighfoward is to use a newline character between each one:

Code: Select all

var1 := "Apples"
var2 := "bananas"
var3 := "Oranges"

multiLine := var1 "`n" var2 "`n" var3

msgbox, % multiLine
; => 
; Apples
; bananas
; Oranges

Using a loop so you can easily add more without having to repeat each variable name:

Code: Select all

A1=Apples
A2=bananas
A3=Oranges

loop, 3
	D .= A%A_Index% "`n"
D := Trim(D, "`n")
MsgBox, % D

The only thing you would have to change if you add more variables is the number of times to loop.

Not sure how you have your data setup but the more sensible way to combine a lot of variables together would be an array.

ahk array object doesn't come with concat or join methods by default; this requires https://chunjee.github.io/array.ahk/#/docs?id=concat and https://chunjee.github.io/array.ahk/#/docs?id=join or similar:

Code: Select all

var1 := "Apples"
var2 := "bananas"
var3 := "Oranges"

multilineString := [].concat(var1, var2, var3).join("`n")
msgbox, % multilineString
; => 
; Apples
; bananas
; Oranges

Thanks Chunjee, could you put that in a loop?

Thanks Chunjee, could you put that in a loop?

Code: Select all

loop,
{
	var1 := "Apples"
	var2 := "bananas"
	var3 := "Oranges"

	multilineString := [].concat(var1, var2, var3).join("`n")
	msgbox, % multilineString
}
