Alright, so I have a ruby file and a text file. The code is like this:
fname = "sample.txt"
somefile = File.open(fname, "a")
somefile.puts "Hello file!"
somefile.close
so what i'd like to do is instead of adding it to the end of the file, add it to a specific line. The text file looks like this:
names
kyle
andrew
joshua
devon
so what I'd like to be able to do it to insert text between "kyle" and "andrew", with each on a seperate line. Please help
Random access is for read-only purpose, if you want to write a random line:
require 'stringio'
tmp = StringIO.open
origin.each do |line|
tmp<<line
if line == 'kyle'
tmp << 'new line !'
end
end
tmp.seek 0
File.open(fname, "wb").write tmp.read
the file then looks like:
names
kyle
new line !
andrew
joshua
devon
