ruby - Rubyファイルそのまま出力

Question

ここで小さな問題が発生しました。

ターミナルに表示される情報とまったく同じ情報で Ruby が新しい .txt ドキュメントを作成することを確認するにはどうすればよいですか?

より明確にするために、たとえば次のスクリプトがあります。

class GradeCalculator
@@new = {} 

def initialize( file ) 
 @file_data = { } 
 File.open( file ) do |file| 
 file.each_line do |line| 
 line_data = line.split( "," ) 
 @file_data[ line_data[ 0 ] ] = line_data[ 1 ].to_i 
 end 
 end 
end 

def maximumgrade( ) 
 @file_data.each do |k, v| 
 if v == @file_data.values.max 
 return v 
 end 
 end 
end 

def change( ) 
 @high = maximumgrade( ) 
 @file_data.map do |k,v| 
 if v != 0 
 @file_data[ k ] = 100 * v / @high 
 @@new = @file_data 
 end 

 end 
end 

def GradeCalculator.show 
 puts " \nExam is passed by:\n" 
    @@new.each{ |k,v| puts "#{k}, #{v}% (grade A+)" if v >= 97} 
    @@new.each{ |k,v| puts "#{k}, #{v}% (grade A)" if v<97 and v>=93}

        puts " \n\n\nExam is failed by:\n" 
        @@new.each{|k,v| puts "#{k}, #{v}% (grade F)" if v < 50} 
end


end 
new = GradeCalculator.new( './Documents/ruby/grades/examresults.txt' ) 
new.maximumgrade( ) 
new.change( ) 
GradeCalculator.show

File.open("newmarks.txt", "w") do |f|     
f.write(GradeCalculator.show)   
end
