    Farthest Frontier

    This is a Lua implementation of the {{indent}} template. Please see the template page for documentation.


    local p = {}
    
    function p.indent(frame)
        -- Trim whitespace from the arguments and remove blank values.
        local args = {}
        if type(frame.args) == 'table' then
            for k, v in pairs( frame.args ) do
                v = mw.text.trim(v)
                if v ~= '' then
                    args[k] = v
                end
            end
        end
        
        -- Set variables.
        local indent = tonumber( args[1] )
        local br = args[2]
        local ret = ''
        
        -- Insert line breaks to match the functionality of the original template.
        -- If "br" is set, we need two line breaks; if not, we just need one.
        if br then
            ret = ret .. '<br />' 
        end
        ret = ret .. '<br />'
        
        -- Control for bad or zero input. If found, output the line breaks only, 
        -- as this was the previous behaviour of the template.

            return ret

        r.mod2 = ' &emsp;' -- To return on modulo 2.
        r.mod3 = ' &emsp;&nbsp;' -- To return on modulo 3.
        
        -- New iteratorText values needed at 5, 9, 13, 17, etc., so repeat the
        -- text (indent - 1)/4 times and find the remainder.
        local reps = math.floor( (indent - 1) / 4 )
        local remainder = math.fmod( indent - 1, 4 )
