For writing text files; especially line by line, it’s perfectly acceptable to use puts
. But, be warned that this will append a line break after the data being written. This behaviour is not desirable when working with binary files, when IO::write
is a better choice to avoid unwanted line break characters.
For example:
file = File.new('temp.file', 'w+') file.sync = true while data = get_data file.write data end file.rewind
