Get string from file and save it as variable's definition?

Ruby
1

require ‘qwikcrypt’ #This is not important, just a encryption gem

password = gets.chomp
encrypted_password = Qwikcrypt::encrypt(content:) #Encrypting the data
:stuck_out_tongue:
Dir.chdir ‘/my/secret/dir’
save = File.open(“secret.txt”)
save.puts("#{password}")
save = File.close

=begin
Next time the program is opened
The following code may not exist
I’m just making it up for you to understand
=end

print "password: "
password = gets.chomp
encrypted = Qwikcrypt::encrypt(content: password)
check = File.open(“secret.txt”) and save string the file contains to
enpass
if password == enpass
puts “success!”
else puts “Username or password do not match!”
end

Help?

Did you try to run this code at all?

“save = File.close” throws an exception, as the File class has no
‘close’ method obviously. You meant “save.close”.

Why not specify the problem with human words?

No, as you can see on the comment I wrote “The following code may not

I actually know that, It was a mistake. Nevertheless it doesn’t answer
my question.

I’m not sure about that.

There isn’t any problem. I just want to know a way to get string from a
file and save it as a variable’s definition.

Example:
#secret.txt contains hello, world!
Dir.chdir ‘path/to/secret.txt’
x = File.open(“secret.txt”)
get string from secret.txt #Turn this into ruby code
save the string to lol #Same goes with this
puts lol

Output:
hello, world!

This question can easily be answered by searching for
e.g. “ruby read string from file” or similar.

I took “The following code” literally. This code is in the “previous”
section.

“save it as a variable’s definition” is complicated, it is simpler to
write “read it into a variable” (this is better for Google)
