[Pharo-project] NetNameResolver in Pharo 1.1

by Lukas Renggli

In Pharo 1.0 there were some problems with the network stack (namely the NetNameResolver) and the IP6 code was reverted shortly before release, see the following issue for details: http://code.google.com/p/pharo/issues/detail?id=1884 Today I was checking with Stef for the presence of these problems in Pharo 1.1, but we could not reproduce neither on Mac, Windows nor Linux. Does anybody have problems with the following expressions in Pharo 1.1? NetNameResolver localHostAddress. NetNameResolver addressForName: 'www.yahoo.com'. Or are we doing the wrong thing to reproduce? Lukas -- Lukas Renggli www.lukas-renggli.ch

Re: [Pharo-project] add return its argument

by Lukas Renggli

That looks good to me. If no additional tests break after loading it, I guess it should be clear to integrate. It is important to have a uniform protocol.

[Pharo-project] We need a UI for Metacello/Loader

by Mariano Martinez Peck

Hi folks. First of all let me clarify that all this email is though for new comers. I think Metacello is a wonderful project and that's why we are adopting it in Pharo. I know Metacello has it's own UI: http://code.google.com/p/metacello/wiki/MetacelloTools I also know there is Metaceller done by Doru. But I think that the features Esteban Lorenzano implemented in GoferProjectLoader are a MUST for a new comer. You can read them here: http://www.smallworks.com.ar/en/community/GoferProjectLoader Now...he doesn't plan to do a UI for that. My question if it would be a good idea to "extend" Metaceller or Metacello-OB so that to uses GoferProjectLoader features. Not necessary for Metacello 1.0 but maybe for 1.1. I think this is important, at least for Pharo. We don't have Universe neither SqueakMap anymore. Cheers Mariano

No. These methods make it good enough (or at least they should, but we know that they don't) to use OrderedCollections as stacks, queues or double-ended queues (which are the common cases), but adding an element before or after another takes O(n) time, compared to lists' O(1). Though this feature can only be used if we allow the users to reference the links directly, otherwise lists have no advantage. > > About performance, i am little concerned. > Linked lists is good , that is costs you a constant time for each new > element you adding. > While for OrderedCollections it vary depending on container state.

That would be true if there was no GC. And as Ralph pointed out, the amortized cost of adding/removing elements to/from the ends of an OrderedCollection is O(1) (or at least it should be, but it's not).

Re: [Pharo-project] Help System

by StÃ©phane Ducasse

Yes in fact we do not really need the helpSystem for that since Setting offer all the necessary behavior. But let us give a try. the KEY POINT is use and improve tests => get executable and always in sync documentation => get better tests because if I know that my tests are used for documentation I will spend time on them.

There's some tests that show "how" to use the class it tests, that can make a good documentation for free.

We don't need to add comments to understand it. So the idea is to tag this test to tell that we can learn from it. Then HelpSystem can built the documentation of XML-Parser package just by collecting the tests. > > Laurent Laffont > > > > >Torsten do you think we could use book.pharo-project.org to populate the help? > > Dont know how the pier books are implemented. > Is it possible to access/parse the contents either on > the server or directly online from a client image? > > If so then yes, as the following example demonstrates: > > > |topic day url sub| > topic := HelpTopic named: 'Last week on Squeak IRC'. > 0 to: 7 do: [:index | > day := (Date today subtractDays: index) printFormat: #(3 2 1 $. 1 2 2). > url := 'http://tunes.org/~nef/logs/squeak/' , day. > sub := HelpTopic > title: day contents: (HTTPLoader default retrieveContentsFor: url) contents. > topic addSubtopic: sub. > ]. > HelpBrowser openOn: topic > > > Bye > T. > > -- > GRATIS fÃ¼r alle GMX-Mitglieder: Die maxdome Movie-FLAT! > Jetzt freischalten unter http://portal.gmx.net/de/go/maxdome01 > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project
