Reading the last n lines from a file without using lots of memory

by phil＠highoctane.be

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

Why do you need a set for that? An array is enough. But please go on. Hilaire -- View this message in context: http://forum.world.st/A-question-about-sets-tp4763094p4765282.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Sorry, a small remark, as you mentioned fonts.

For the background color: This works only for the background of the list cells. If there is no entry in your listmodel list, the list view is empty as well and there is nothing to show. This works: ListModel new items: (1 to: 10); backgroundColorBlock: [ :item :index |Color red ]; openWithSpec. or with more colors :) ListModel new items: Color registeredColorNames ; backgroundColorBlock: [ :item :index | Color named:item]; openWithSpec.

Re: [Pharo-users] A question about sets

by Alain Busser

About the use of sets I found another idea: Eratosthene's sieve. Basically you create a set containing all integers from 2 to, say, 200. Then, beginning with 2, you choose remove all multiples of the number you choose from the set. Then you go to the next number in the set and so on... The difficulty is to choose the right collection, as a set is not ordered and it is not easy to loop on the prime divisors... I made it on this article (near the middle): http://irem.univ-reunion.fr/spip.php?article742 Of course you can have the set of primes directly under Pharo with isPrime as we did here: http://www.epi.asso.fr/revue/articles/a1211b.htm (I had forgotten this) Alain On Thu, Jun 26, 2014 at 8:21 PM, Hilaire Fernandes < hilaire.fernandes(a)gmail.com> wrote: > Great! > Now I wonder how it could be used within Dr. Geo. > > Thanks > > Hilaire > > Le 25/06/2014 18:33, Alain Busser a Ã©crit : > > About the birthday problem, I already pulished something that I had > > exeperimented in the classroom, but it is in French: > > http://irem.univ-reunion.fr/spip.php?article618 (clic on "problÃ¨me des > > anniversaires" tab).

Re: [Pharo-users] Loading petitparser when Voyage is loaded is taking an awful long time

by phil＠highoctane.be

I use it. Now, how can one paste text in the lower pane? I can't get that working and it is frustrating. Especially when I do have long external samples. I also got some out of memory errors when a grammar loops on itself in a wrong way. Which is what happend when trying things out. There should be a kind of limit one could customize. Especially when hitting 'example'tab... :-) I should have a shot at GT... I am using Pharo3.

If you want to use PetitParser at full speed, you should take a look at the dedicated PetitParser browser: PPBrowser open. And if you want to really go into it, you can also use the dedicated inspector and debugger from GT.
