- !ruby/struct:SM::Flow::P
body: Returns (and assigns to <tt>$_</tt>) the next line from the list of files in <tt>ARGV</tt> (or <tt>$*</tt>), or from standard input if no files are present on the command line. Returns <tt>nil</tt> at end of file. The optional argument specifies the record separator. The separator is included with the contents of each record. A separator of <tt>nil</tt> reads the entire contents, and a zero-length separator reads the input one paragraph at a time, where paragraphs are divided by two consecutive newlines. If multiple filenames are present in <tt>ARGV</tt>, +gets(nil)+ will read the contents one file at a time.
