Hey folks!

Is it possible to loop parse backwards?
I tried the following but won't work

Colors = red,green,blue
Loop, parse, Colors
{
    MsgBox, Color number %A_Index% is %A_LoopField%.
    if (...)
        [color=#FF0000]%A_Index%--[/color] [color=#00BF00]; repeat latest %A_LoopField%.[/color]
}

thanks!

Hey Guest,
Can you show an example of how that works ?

Even "msgbox % priorLoopField" doesn't seem to work as OP inteded.

Try this:

Colors = red,green,blue

Loop, parse, Colors, `,

    forsort .= a_index "/" a_loopfield ","

sort, forsort, N R D,

stringtrimright, forsort, forsort, 1

loop, parse, forsort, `,

{

    stringsplit, color, a_loopfield, /

    MsgBox, Current Color is %color2%

}

If you're going to use StringSplit you may as well use it from the beginning:

Colors = red,green,blue
StringSplit, n, Colors, `,
Loop %	n%0%
{
	a :=	n%0% + 1 - A_Index
	MsgBox %	"Current color is " n%a% "."
}

... could also push the colors to an array, & then enumerate it:

Colors = red,green,blue

array := []



Loop Parse, Colors, `,

   array.insert(1, A_LoopField)

For Each, color in array

   MsgBox %   "Current color is " color "."

Here's an interesting way to do it using RegExMatch and the Occurrence parameter of InStr:

Colors=red,green,blue
StringReplace, Colors, Colors, `,, `,, UseErrorLevel
Loop %	(c :=	ErrorLevel + 1)
{
	RegExMatch(Colors,"[^,]+",item,(A_Index=c) ? 1 : InStr(Colors,",",0,1,c-A_Index))
	MsgBox %	item
}
