Hi hernan it was nice to meet you :) This is the old way to define preference we will get rid of them... The rigt way is to have a classVar or something at the level of the packages that does it and to trigger it via the setting framework. > addPreference:categories: I imgaine that soon alain will publish a new version and we will integrate it.

Thanks. speed up the system was always a concern to us now the font rendering takes time and we have all new machines so we do not feel the slugginess. Now this is important and in 1.1 we already got 15% speed increase for morphic.

It's easier for beginners to speak in their native language. Not every one is a core Pharo developpers, some people are just plain users that want to expose their problems. In french, we have only one mailing with all the Smalltalk flavors. You can talk also about specific needs for example the translation of books in your language or some local events. -- Serge Stinckwich UMI UMMISCO 209 (IRD/UPMC), Hanoi, Vietnam Smalltalkers do: [:it | All with: Class, (And love: it)] http://doesnotunderstand.org/

Re: [Pharo-project] Spanish Mailing list for Pharo

by Alexandre Bergel

As soon as a significant effort is required to communicate in a foreign language, then everybody may loose something. A Spanish mailing list is as important as a French or German one. SqueakRos apparently is quite active and has many participants. I will simply use it to share my views on Pharo and maybe Moose.

Sorry Alex, I wanted to speak with you about this in Smalltalks 2009 but I couldn't find it. My personal view is that I am not sure if it would be good to have a Pharo in Spanish mailing list. Why ? Most of the Argentinian (and I guess others spanish countries also) people speaks english. At least well enough to communicate. And even more nowadays where you have google translate and all that stuff. So, maybe those you are not use to speak english they do a little effort. With this, everybody can read those emails.

Re: [Pharo-project] Pharo and db support

by Mariano Martinez Peck

Ok.....Doru: I will answer you as much as I know. I think it is good your idea of having a webpage with all the answers of your questions and even more. The seaside persistence page is ok, but two things: 1) this is not only squeak/pharo but others dialects too, 2) Most of those persistence strategies are not seaside dependent. I mean, you can use them in others contexts, not only seaside. Maybe we can modify http://code.google.com/p/pharo/wiki/PackagesTestedInPharo and put more information. what do you mean by "Projects that use this one" ? projects like Glorp or enterprise/company projeccts ? Regarding SqueakDBX there are two projects: SqueakDBX itself and GlorpDBX. SqueakDBX is just the database driver. *Maturity*: SqueakDBX has raised the "stable" maturity. *Version*: You can have in Universe 1.0 and 1.1 (which is the latest one). For stable releases we use Universe and SqueakMap, but not MC. However, most of the time, the latests versions in MC are "working". I know this is not the best approach and we can use Metacello or Sake but we didn't have time yet. In this moment, you can install the latests version and will work perfect. You can take the latest Pharo image (core, dev or web), download the package SqueakDBXLoaders and then just evaluate SqueakDBXPharoLoader loadSqueakDBX. *Supported database vendor and version*: I can told you the "tested" databases, but not the supported. Because I don't know. Maybe it works and maybe it doesn't.We have tested the following databases: Oracle (I think 9 and 10, but I guess it should work on 11), MySQL 5 (in 4.1 we have some problems but there is some work done), PostgresSQL 8.X, Sqlite3.XXX, MSSQL 2005 and 2008. *Current development*: GlorpDBX and fixing bugs when reported *Maintance support*: we are here :) we have our own mailing list: http://lists.squeakfoundation.org/mailman/listinfo/squeakdbx *Website*: www.squeakdbx.org GlorpDBX: We did two things: we refactored Glorp so that it is not couple to the native postgresql driver anymore but to an API (abstract database driver). And then, we create a concrete Glorp driver for SqueakDBX (that's what we call GlorpDBX) and another one for the postgresql native driver. *Maturity*: Yet in development. Thanks to ESUG for the sponsoring on SummerTalk 2009. Right now we have postgresql, mysql and oracle green tests. We will then work on MSSQL support. *Version*: There is no release yet, but you can download the latest from MC. Just download the package SqueakDBXLoaders and evaluate SqueakDBXLoader loadGlorpDBX. The problem here is Glorp. The Glorp port we have in Squeak is too old. We plan to do a new port from VW but this is quite complicated as there is no exporter from Store to MC as I understand. *Supported database vendor and version*: I can told you the "tested" databases, but not the supported. Because I don't know. Maybe it works and maybe it doesn't.We have tested the following databases: Oracle (I think 9 and 10, but I guess it should work on 11), MySQL 5 (in 4.1 we have some problems but there is some work done), PostgresSQL 8.X. *Maintance support*: we are here :) *Website*: www.squeakdbx.org There is also the native postgresql driver which also works on Pharo and it has no dependencies. In addition, you can load Glorp with our refactor and a new Glorp driver we did but using the postgresql native driver. To do this, you must download GlorpPharoLoader and evaluate loadGlorpWithNativePostgreSQLDriver. There is also Magma than in the few months they did a lot of work and now it works also in Pharo. Ok....that's all I could tell you. I don't have a pharo image here so maybe some of the messages I told you are wrong :( Cheers, Mariano On Thu, Nov 26, 2009 at 7:44 PM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr > wrote: > > On Nov 26, 2009, at 11:38 PM, Diogenes Moreira wrote: > > > A OK.. > > > > SqueakDbx http://www.SqueakDBX.org > > > > with Glorp. http://www.glorp.org > > > > which version.... live in the trunk is more fun. :) > > well. > I just got a discussion with doru that this is a pain to load the latest > version of something > because you cannot load a previous and robust set of consistently working > together versions. > Soon people will have to offer metacello configuration. > > > > > > Best Regards. > > > > On Thu, Nov 26, 2009 at 7:06 PM, Tudor Girba <tudor.girba(a)gmail.com> > wrote: > >> Hi, > >> > >> That sounds interesting indeed. > >> > >> But, I was more talking about the projects for DB mapping, not the > >> application projects.
