[Pharo-project] [ANN] New SqueakDBX release and good news!!!
by Mariano Martinez Peck Oct. 11, 2009

Oct. 11, 2009

Hi folks! We have a couple of things to announce. 1) First of all we gave a ESUG 2009 presentation. You can find the slides here: http://www.slideshare.net/esug/squeak-dbx 2) Then, we created the first version (some bugs, default Pier css, etc) of our website using Seaside + Pier. You can see it temporarily here: http://squeakdbx.smallworks.com.ar However, it will be then: http://www.squeakdbx.org/ Now, the swiki: http://wiki.squeak.org/squeak/6052 is deprecated. 3) Remember we created our own mailing list for questions or whatever you want: http://lists.squeakfoundation.org/mailman/listinfo/squeakdbx 4) There are real interests from other people to port SqueakDBX to dolphin and Smalltalk/X so, we will try to do that easier ;) 5) There is a new release of SqueakDBX: 1.1. The most important thing with this release is that we now support MySQL, PostgreSQL, Sqlite3, Oracle and MSSQL in Windows, Linux and Mac. We also did some refactors which arrived in better performance. You can see the complete changeset here: http://squeakdbx.smallworks.com.ar/ChangeLog The OpenDBX version you need is 1.4.4. You can compile or use the binaries. Here you have the instructions to install OpenDBX: http://squeakdbx.smallworks.com.ar/Compiling%20and%20installing%20OpenDBX SqueakDBX installing instructions: http://squeakdbx.smallworks.com.ar/Installation As always, any feedback, comments or whatever is more than welcome. Best, Mariano

[Pharo-project] [ANN] New Aconcagua & Chalten packages

Reminds me again how close Smalltalk comes to the real world. Dont know if the interest rate of 0.1 is still valid after the financial crisis ;) but I always liked this natural expression style of Smalltalk: initialCapital := 100 dollars. interestRate := 0.1 / 1 year. Especially the ease of "1 year", "1 month" or "Date today". If you ever worked with the date and calendar mess in Java you know what I'm talking about. I can even write: 100 m2 100 USD 100 EUR 100 â¬ Unfortunately I cant (yet) write unary messages like this in Smalltalk: 100 $ 100 % Wonder why not. Parser gives "Message pattern expected", maybe because of unary vs. binary. Have to think about it ... -- GRATIS fÃ¼r alle GMX-Mitglieder: Die maxdome Movie-FLAT!

I suggest you to read the chapter on the Smalltalk model in the Squeak or pharo by example book the key is: when you look for a message you look in the CLASS of the receiver then its superclasses. So when you look for new sent to Array you should look in the Array class superclasses and you will see it contains Behavior before ProtoObject Stef PS: you can sent to the mailing-list just register to it. You do not need to have a google account.

[Pharo-project] Loading Gemstone Variable (Indexable) classes into Pharo via Monticello
by rkrock＠locksleycreeksoftware.com Oct. 8, 2009

Oct. 8, 2009

I have the following in Gemstone: FristClass which is a indexableSublass of Object. SecondClass which is a subclass of FirstClass. When I save this to Monticello and then load it into Pharo, the load fails on the 'recompile' because the SecondClass is not of type #variable. The load works when I modify the method MCClassDefinition>>createClass to use the superclass' type when the superclass type is #variable. --- current way ---- ... type: type; ... --- hacked way ---- .... type: ((superClass typeOfClass isSymbol not and: [superClass typeOfClass isVariable]) ifTrue: [superClass typeOfClass] ifFalse: [type]); .... With this I was sucessfully able to important the code into Pharo. I am able to go from Pharo to GemStone with no problems. Is there a general solution to this problem? It obviously will not occur very often. Regards, Reg
