class Tracksperanto::ExtIO
Many importers use this as a standard. This works like a wrapper for any IO object with a couple extra methods added. Note that if you use this in an importer you need to wrap the incoming input with it yourself (that is, an IO passed to the import module will NOT be wrapped into this already)
io = ExtIO.new(my_open_file) io.gets_non_empty #=> "This is the first line after 2000 linebreaks"

Similar to IO#gets however it will also strip the returned result. This is useful for doing
while non_empty_str = io.gets_and_strip
because you don't have to check for io.eof? all the time or see if the string is not nil
# File lib/tracksperanto/ext_io.rb, line 17 def gets_and_strip s = gets s ? s.strip : nil end
gets_non_empty()

Similar to IO#gets but it skips empty lines and the first line returned will actually contain something
# File lib/tracksperanto/ext_io.rb, line 23 def gets_non_empty until eof? line = gets return nil if line.nil? s = line.strip return s unless s.empty? end end
