slight improvement for handling unexpected-and-wanted whitespace around the # delimiters; %s? --> %s* i.e. possible single whitespace char --> zero or more whitespace chars

New page

local p = {}

-- Unescape functionality grabbed from https://stackoverflow.com/a/14899740/1832568
local function unescape(str)
str = string.gsub(str, '&#(%d+);', string.char)
str = string.gsub(str, '&#x(%d+);', function(n) return string.char(tonumber(n, 16)) end)
return str
end

-- Counting function accepting a string haystack and table of needles
local function count(haystack, needles)
local number = 0
-- While we have needles to look for
for index, needle in ipairs(needles) do
-- find them all in our haystack
for m in string.gmatch(haystack, needle) do
number = number + 1
end
end
return number
end

-- Function takes any number of # delimited page names and section level numbers
function p.main(frame)
local total = 0
local needles = {}
local haystack = ''
-- Separate page names from # delimited string into table
local pages = mw.text.split(unescape(frame.args[1]), '%s*#%s*')
-- Separate whitespace delimited section level numbers into table
local levels = mw.text.split(frame.args['level'], '%s*')
-- Iterate through levels
for level in mw.text.gsplit(table.concat(levels), '') do
-- and add the level needle to needles
needles[#needles + 1] = '\n'..string.rep('=', tonumber(level))..'[^=]'
end
-- For each page name in pages
for index, page in ipairs(pages) do
-- create a haystack to search from the page content
haystack = mw.title.new(page):getContent()
-- If we've requested the content of a legitimate page
if haystack then
--[[ pass the raw markup and needles to count
and add the return to total ]]
total = total + count('\n' .. haystack, needles)
end
end
--[[ then return how many sections of the required level
are in all the pages passed ]]
return total
end

return p
