Create text files

Ruby
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.

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
