Novice here. I'm reading Beginning Ruby and Beginning Rails by Apres and
building both applications they walk you through. Additionally, I'm
taking courses at lynda dot com and attempting to build a simple
application myself.
That said, I'm aware of the limits you have with local variable being
incapable of accessing variables defined inside of a code block, but is
there any exception to this rule?
Example:
···
_____________
1.times do
File.open("text.txt").each {|a| puts a}
end
puts a
# This where I get my error.
_____________
Is there anything I can do to 'puts a' that will allow it to return the
content it was passed inside of the code block?
Ultimately, I'd like to store the 'text.txt' as an array so I can call
.uniq! on it... But we don't need to get into that in this thread.
