--- Allows for consistent treatment of boolean-like wikitext input.
--- Uses lookup table, instead of if-elseif-else statement, for efficiency.
--
-- If your wiki uses non-ASCII characters for any of "yes", "no", etc., you
-- should replace "string.lower" with "mw.ustring.lower" in the
-- following line. NOTE: It is _much_ slower.
local LOWER = string.lower
local TO_NUMBER = tonumber
local TYPE = type
local BOOLEAN_MAP = {
yes = true, y = true, ['true'] = true, t = true, on = true, ['1'] = true,
no = false, n = false, ['false'] = false, f = false, off = false, ['0'] = false
}
return function (value, defaultResponse)
if value == nil then
return nil
end

local valueType = TYPE(value)

if valueType == 'boolean' then
return value
elseif valueType == 'string' then
local lookupResult = BOOLEAN_MAP[LOWER(value)]
if lookupResult ~= nil then
return lookupResult
end
end

-- Numeric check works for both numbers and numeric strings.
local number = TO_NUMBER(value)
if number == 1 then
return true
elseif number == 0 then
return false
end

return defaultResponse
end
