local p = {}

--[=[
Similar to gmatch, but it returns the count of the match in addition to the
list of captures, something like ipairs().

If the pattern doesn't contain any captures, the whole match is returned.

Invoke thus:

for i, whole_match in require("Module:string").imatch(text, pattern) do
[ do something with i and whole_match ]
end

or

for i, capture1[, capture2[, capture3[, ...]]] in require("Module:string").imatch(text, pattern) do
[ do something with i and capture1 ]
end
]=]

function p.imatch(text, pattern, start, plain)
local i = 0
local pos = start or 0
if not mw.ustring.find(pattern, "%b()") then
pattern = "(" .. pattern .. ")"
end
return function()
i = i + 1
local return_values = { mw.ustring.find(text, pattern, pos, plain) }
local j = return_values[2]

if #return_values > 0 then
pos = j + 1
-- Skip the first two returned values, which are the indices of the
-- whole match.
return i, unpack(return_values, 3)
else
return nil, nil
end
end
end

return p
