Problem with files comparing

Hi, there

My problem is to compare two files in the same directory as the program
does.

the code is:

require ‘ftools’
def fcmp
from = ‘my_log.txt’
to = ‘my_log_e.txt’
if compare(from,to, verbose = false) then
puts ‘Identical.’
else
puts ‘Different.’
end
end

After running the function. There’s no result as all. Is there anybody
has the idea what’s wrong with it?

You probably need to call your function.

Hi, Dave

I tried put them in a class, and tested, but it kept throwing me the
error message. The code and error message are in the following:

class Cmprocess

Create the object

def initialize(from,to)
@from = from
@to = to
end

def fcmp
require ‘ftools’
compare(@from,@to, true)
end

r= Cmprocess.new(“my_log.txt”,“my_log_e.txt”)

if r.fcmp then
puts “Identical files.”
else
puts “Different files.”
end

end

C:\Documents and Settings\cheynel\My
Documents\NetBeansProjects\task1\lib\fcmp.rb:11:in fcmp': undefined methodcompare’ for #<Cmprocess:0xb40ec4 @to=“my_log_e.txt”,
@from=“my_log.txt”> (NoMethodError)
from C:\Documents and Settings\cheynel\My
Documents\NetBeansProjects\task1\lib\fcmp.rb:16
from C:\Documents and Settings\cheynel\My
Documents\NetBeansProjects\task1\lib\fcmp.rb:2

I used netbean for ruby to ran it

  1. It’s relatively unusual to create instances of a class inside the
    class body, but that won’t cause this problem

  2. Where do you define the ‘compare’ method?

compare is a std mathod in ftools.rb

Then you’d need to say File.compare, and not just compare.
