def expand_path(base, relative, pop = true)

Parameters:
  • pop (Boolean) -- whether to remove the last path component of the base path, to conform to URI merging behaviour, as defined by RFC2396. 
def expand_path(base, relative, pop = true)
	if relative.start_with? "/"
		return relative
	end
	
	path = split(base)
	
	# RFC2396 Section 5.2:
	# 6) a) All but the last segment of the base URI's path component is
	# copied to the buffer.  In other words, any characters after the
	# last (right-most) slash character, if any, are excluded.
	path.pop if pop or path.last == ""
	
	parts = split(relative)
	
	# Absolute path:
	if path.first == ""
		expand_absolute_path(path, parts)
	else
		expand_relative_path(path, parts)
	end	
	
	return path.join("/")
