Excellent. Mark you should create a bug entry on fogbuz and like that we will review and integrate your improvements! I want them :) You should sign the license agreement too :) On 28/6/14 09:12, Mark Rizun wrote: > I'm making first small steps in my refactoring project.

Re: [Pharo-users] A question about sets

by Alain Busser

You're right but it should not have a fixed length because I want to remove numbers from it. I guess an SortedCollection is the best way to retrieve the next prime number. And the exercise is a good way to discover select and reject... Alain On Fri, Jun 27, 2014 at 1:41 PM, hilaire <hfern(a)free.fr> wrote: > Why do you need a set for that?

Re: [Pharo-users] Reading the last n lines from a file without using lots of memory

by phil＠highoctane.be

Thanks. But this would give me the 200 last chars. I am interested in the 200 last lines. Now, I did this: command := 'tac ', file fullName, ' | head -200'. ^ (PipeableOSProcess command: command) output. which did the trick but isn't portable at all (Linux here). I had a look at RemoteString as well.

If you have a MultiByteFileStream you can do stream position: stream size - 200. stream next: 200. Have a look at RemoteString, which is the class used to read the source from the source and changes files (without loading all of them into memory) On Fri, Jun 27, 2014 at 6:15 PM, phil(a)highoctane.be <phil(a)highoctane.be> wrote: > I wonder how you guys would read the last n lines from a file in Pharo > without reading through the whole thing. > > Is there code doing just that somewhere? > > The code I have is a shell script doing a 'tac file | tail -200 > > /temp/something' > > I can always do that through OSProcess but wondered if there was something > available. > > Reading through with a 200-entries FIFO circular buffer seems a bit silly > to do. > > TIA > Phil > > >
