Hi, I’m kinda new to this programmin thing and I’m currently using  
windows vista and it seems whenever I run this file:

line = File.readlines(“text.txt”)  
lines\_count = lines.size  
text = lines.join  
puts “#{line\_count} lines”

It will show :

> ruby C:/Users/administrator/analyzer.rb  
> \*\*\* WARNING \*\*\* Windows users should check the “Run process in terminal”  
> check box in the Debugger Preferences  
> to see STDOUT and STDERR output in real time.

C:/Users/administrator/analyzer.rb:2: undefined local variable or method  
`lines’ for main:Object (NameError)

> exit

and as you can see, there’s an error in the code but I can’t seem to  
find out what. I have attached the text maybe someone can run it and  
tell me what’s wrong?

Thanks,

Gen

The error message does tell you exactly the problem: it’s on line 2 of  
analyzer.rb, and the problem is that you referred to something called  
“lines” but no such thing exists. That is, there is no local variable or  
method called “lines”

On line 1 you created a local variable called “line”, not “lines” 🙂

HTH,

Brian.

In this group, it usually means “hope that helps”, or “hope that  
helped”.

You can google internet acronyms to see some others in use. There’s  
also a wiktionary page dedicated to such a thing:
