# Open / create temp file
temp_file = Tempfile.new(["myfile",".txt"])

# Write into temp file (this is where the problem is... I believe the myprogram is creating a new file)
raise "Problem with my proggy" unless system "/usr/local/bin/myprogram '#{temp_file.path}'"

# Read from temp file
puts temp_file.read

# Close / delete temp file
temp_file.close!

--
- myprogram inserts data into temp_file
- temp_file.read sometimes returns back results... other times it doesn't
- i've also attempted to re-open the file:  temp_file.reopen(temp_file.path,"r") with the same result


my goal is:
- have Tempfile create a new and random temp filename inside of <templocation>
- have my external process write into this random temp filename
- read from this external file
- delete the temporary file

Unfortunately, I can't pipe or print the information from myprogram.  It must be written out to a file...



Here's my work-around... which seems a bit messy:

    # Create temp file, destroy temp file
    temp_file = Tempfile.new(["myfile",".txt"])
    text_file_path = temp_file.path
    temp_file.close!

    # Run proggy (which creates temp file)
    raise "Problem with my proggy" unless system "/usr/local/bin/myprogram '#{text_file_path}'"

    # Re-open file, Get dataz
    temp_file.reopen(text_file_path,"r")
    puts temp_file.read

    # Close file, clean up tmp
    temp_file.close
    File.unlink(text_file_path)
