For example, I have the string

red`nblue`ngreen`nred`nblack

The second "red" is a duplicate. Are there exiting functions in AHK to check it?
(Otherwise, an extra loop is not that hard ..)

you can use sort to remove duplicates. Or you can use instr twice, eg,

Code: Select all

f1(haystack, needle){	; finds duplicates without considering a delimiter
	local
	return (p := instr(haystack, needle)) && instr(haystack, needle,, p + 1)
}

f2(haystack, needle, del := "`n"){	; for when haystack is a delimited list
	local
	needle := del . needle . del
	haystack := del . haystack . del
	return (p := instr(haystack, needle)) && instr(haystack, needle,, p + 1)
}

You can also use regex, I leave that as an exercise

.

Cheers.
