How big is pl?
Can you
(a) replace 'N' with '.' in the strings in pl
(b) turn your loop inside out and use gmatch [1] over read
?
Something like:
local function slide_over_read(read, pl)
for patt, tbl in pairs(pl) do
for w in read.gmatch(patt) do
-- do something with the matched substring w and table tbl
end
end
end
