Create text files

ruby-talk
1

Hi,

I do have a text file as shown below. I'd now like to use Ruby to create
separate text files for the content between "======". To do so I have:

# Open, read from a text file, and pass to block f1
File.open('test.txt', 'r') do |f1|
  while line = f1.gets
     puts line
  end
end

# Create a new file and write to it
File.open('cve.txt', 'w+') do |f2|
   if f2 =~ /Name/
     puts line
   end
end

Though cve.txt is empty and I just have one cve.txt. Pls advise. I
appreciate.

Test.txt

Dear Tom,

you could do the following:

all_text=IO.readlines("test.txt").to_s.split(/\=+/)
name_regexp=/Name: ([^\n]+)/
all_text.each{|entry_between_equal_signs|
      file_name=name_regexp.match(entry_between_equal_signs)
      if file_name!=nil and File.exists?(file_name[1]+'.txt')==false
        f=File.new(file_name[1]+'.txt','w')
        f.puts entry_between_equal_signs
        f.close
      end
}

Best regards,

Axel
