I'm reading this sentence as a set of requirements. Assuming that the arrays are small enough to not blow out the RAM on the machine, I'd do it like this: ## main_file = ['a','b','c',' '] latest_data = ['c','x'] not_in_main_file = latest_data - main_file puts "not in main file: " puts not_in_main_file puts "" new_log = main_file + not_in_main_file puts "new log contents after addition: " puts new_log ___ Wtr-general mailing list Wtr-general@rubyforge.org http://rubyforge.org/mailman/listinfo/wtr-general

Re: [Wtr-general] [OT] - array nightmare
Hi Chris I think the biggest issue is the difference between File.read and IO.readlines, and understanding when an array or a string is returned. I'm not comfortable with truncating the original file either. What I would like to do is get the latest data, see what's not in the main file, and append it. What I do now, is get the latest data, put the existing file into an array, merge the two and hack it with Array.sort.uniq, truncate the file and insert the new data. Anyway, as I said, off topic so don't worry too much - this solves a sort-term problem.

[Wtr-general] [OT] - array nightmare
Hi list
Off topic, but I am sure there is a better way to do what I'm doing.
As my test script runs, I have a script which reads the windows event
log every 5 minutes and produces three flat files with the output
according to different criteria. The way I read the logs is with
Microsoft's dumpel.exe utility which is called with system() and
parameters from ruby.
But, I need a continuous log file, so at the beginning of the script I
create a master log file. Everytime the three new temp log files are
written, I read the data into an array. I also read the master log file
into an array. Then I have a simple if:
oldbuffer = logfile.to_a
newbuffer = nil
newbuffer = rebootedarray.to_a | clearedarray.to_a | temparray.to_a
newbuffer.each {|item|
if not oldbuffer.include?(item)
oldbuffer.push(item) if item > ''
end
}
logfile.truncate 0
oldbuffer = oldbuffer.sort.uniq
logfile.puts(oldbuffer)
The new array replaces all the data previously in the master log file. I
get a lot of redundant whitespace for some reason. It really is a hack -
there must be a better way to do it...
