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.
