Terasail: Create from Module:Archive list

Create from Module:Archive list

New page

-- This module was created from [[Module:Archive list]] and only some
-- lines were changes in order to search for alphabetical archives

-- This module implements {{Archive list alpha}} in Lua, and adds a few
-- new features.

-- Converts the integer counter for an archive to an alphabetical string
local function numToLetters(newInt)
newInt = newInt - 1
local modVal = newInt % 26
local newLetter = string.char(string.byte('A') + modVal)
if newInt >= 26 then
return numToLetters(math.floor(newInt / 26)) .. newLetter
end
return newLetter
end

-- Process a numeric argument to make sure it is a positive
-- integer.
local function processNumArg( num )
if num then
num = tonumber( num )
if type( num ) == 'number' then
num = math.floor( num )
if num >= 0 then
return num
end
end
end
return nil
end

-- Checks whether a page exists, going through pcall
-- in case we are over the expensive function limit.

end

-- that the page doesn't exist.
return false
else
if titleObject then
return titleObject.exists
else
return false -- Return false if given a bad title.
end
end
end

-- Checks every nth archive to see if it exists, and returns the
-- number of the first archive that doesn't exist. It is
-- necessary to do this in batches because each check is an
-- expensive function call, and we want to avoid making too many
-- of them so as not to go over the expensive function limit.

-- and starting in intervals of 1000. This should get us a
-- maximum of 500,000 possible archives before we hit the
-- expensive function limit.
