--- !ruby/object:RI::MethodDescription aliases: [] block_params: comment: - !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. - !ruby/struct:SM::Flow::VERB body: " ARGV << "testfile"\n print while gets\n" - !ruby/struct:SM::Flow::P body: <em>produces:</em> - !ruby/struct:SM::Flow::VERB body: " This is line one\n This is line two\n This is line three\n And so on...\n" - !ruby/struct:SM::Flow::P body: The style of programming using <tt>$_</tt> as an implicit parameter is gradually losing favor in the Ruby community. full_name: Kernel#gets is_singleton: false name: gets params: | gets(separator=$/) => string or nil visibility: public
