p format - ruby bug? - dumb program?

[KONTRA Gergely]

Hi!

Can I specify how strings are printed, when using the p function?
I mean with ' or with " ?

---
During running a little program, which detects files with the same
content, I get a ruby bug:
processing dir c:\WINDOWS\SYSTEM\VMM32

abnormal program termination

It is a self-compiled ruby.

The program follows: BTW: can anybody simplify it, or make it clearer.
It seems to work, but I think it can be written more compact...
(I wrote it in python (I don't know python, I just tried it), and the
outputs are different.)
============================================================
$files=Hash.new { [] } # {theSize=>[[fn1,fn2],[fn3]]} fn1 and fn2 have same content

def equalFiles? fn1, fn2
f1=File.open fn1,'r'
f2=File.open fn2,'r'
while chunk1=f1.read(512)
chunk2=f2.read(512)
return false if chunk1!=chunk2
end
return true
end

def processDir(dir='.')
$stderr.print "processing dir #{dir}\n"
Dir.foreach(dir) {|f|
begin
next if f=='.' or f=='..'
fn=dir+'\\'+f
if File.directory? fn
fnprocessDir fn
else
elsesize=File.size fn
fnif
fnif ($files[size]).each{|fn2| # process each segment
segment if equalFiles? fn,fn2[0]
fn2 #fn2.replace fn2.push(fn)
fn fn2<<=fn
fn break nil
nil end
end }
end $files[size]<<=[fn]
fnend
end
rescue
$stderr.print "Ooops #{fn}: #$!\n"
end
}
end

processDir ARGV[0]
puts '='*60
$files.sort.each {|h|
size,arr_size=h
arr_size.each {|segment|
if segment.size>1
print "#{size} -> "
p segment
end
}
}
============================================================

It is hard coded in String#inspect method, so you have to
override it.

class String
alias __inspect_orig__ inspect
def inspect
s = __inspect_orig__()
s.sub!(/'/, "\\\\'")
s.sub!(/\\"/, '"')
s.gsub!(/(\A"|"\z)/, "'")
end
end

code snippet:

def equalFiles? fn1, fn2
f1=File.open fn1,'r'
f2=File.open fn2,'r'
while chunk1=f1.read(512)
chunk2=f2.read(512)
return false if chunk1!=chunk2
end
return true
end

The problem was: files are opened, but none of them are closed
explicitly. The ruby output is a bit misleading. Can it be improved?

Seems to be due to msvcrt.dll's bug. Usa reported 6.00.8397.0
has no such problem.
