How can I split-by-hyphens, but not remove the hyphens?

I want to turn a string like "hello-world" into a list of strings: {"hello-", "world"}

I can easily split by hyphens:

local r = {}
for word in text:gmatch("[^-]+") do
	table.insert(r, word)
end

and I can approximately put it together by assuming each word was followed by a hyphen:

for i, word in pairs(r) do
	if i < #r then
		word[i] = word[i] .. "-"
	end
end

but that is assuming that there is precisely one hyphen after each word and that the string doesn't start or end with hyphens.

I was considering something like this:

local r = {}
for word in text:gmatch("%-|[^-]+") do
	table.insert(r, word)
end

but Lua string patterns doesn't have support for "either" (what I wanted by the |), so that pattern doesn't work.

Is there any way to do this without going character-by-character?

More examples:

"--a--b---c" --> {"--a--", "b---", "c"} or {"--", "a--", "b---", "c"} -- I don't care which

"hello-there-person" --> {"hello-", "there-", "person"}

"hello" --> {"hello"}

Edit Ok remembered I can use *, and now my method is great :)

local k = {"hello-world", "--a--b---c", "hello-there-person", "hello"}

local listOfStrings = {}

for _,d in pairs(k) do
	d:gsub("(-*[^-]+-*)", function(x)
		table.insert(listOfStrings, x)
	end)
end
