Copying values from a different file into variables

ruby-talk
1

I would like to copy specific lines(contents) from file1 into file2.

# File1 has following information:

browser = "firefox"
id = "test@testuser.com"
password= "12345678"
account = "Yes"

# I want the following information in File2 :

@var1 = "firefox" (value of browser from File1)
@var2 = "test@testuser.com" (value of id from File1)
@var3 = "12345678" (value of password from File1)

How do i get this done using ruby. Please let me know if you require
more clarification on this front.

Cheers

You'd generally get more help if you try to do some of the work and then post if/when you get stuck.

# File1 has following information:

browser = "firefox"
id = "test@testuser.com"
password= "12345678"
account = "Yes"

# I want the following information in File2 :

@var1 = "firefox" (value of browser from File1)
@var2 = "test@testuser.com" (value of id from File1)
@var3 = "12345678" (value of password from File1)

I haven't used ruby that long but something like

File.open("file2", "w") do |f2|
   count = 1
   File.foreach("file1") do |line|
     f2 << line.sub(/^[\w\s]+=/, "@var#{ count } =")
     count += 1
   end
end

could work. (skipping the creation of @var4 for the "account" line is left as an exercise for the OP)
