This is a Lua implementation of the {{in5}} template. Please see the template page for documentation.

-- This module implements {{in5}}.

    -- Trim whitespace and convert to number. Default to 5 if not present,
    -- as per the template title.
    indent = tonumber( mw.text.trim(indent) ) or 5
    -- Round down to nearest integer. Decimal values produce funky results
    -- from the original template, but there's no need for us to replicate that.
    indent = math.floor( indent )
    -- Don't output anything for zero or less. Again, there was some funky output
    -- here for negatives, but now we're in Lua we should use sane defaults.
