Hi, I try to use SqueakDBX on Mac OS X 10.6. I have downloaded and compiled the libraries for PostgreSQL, MySQL and finaly compiled and installed openDBX.

I have downloaded the OneClick distribution of Pharo 1.2.1 and installed SqueakDBX and GlorpDBX. Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfSqueakDBX'; load. ConfigurationOfSqueakDBX project latestVersion load. Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfGlorpDBX'; load. ConfigurationOfGlorpDBX project latestVersion load. Now, I try to do a SQL request to MySQL: connect | conn connectionSettings result | connectionSettings := DBXConnectionSettings host: 'mysql.domaine.fr' port: '3306' database: 'test' userName: 'username' userPassword: 'hello'. conn := DBXConnection platform: DBXMySQLPlatform new settings: connectionSettings. conn connect. conn open. result := conn execute: 'SELECT * from data'. DBXTranscript show: result. conn close. But I get an error : 'Unable to find function address' SqueakDBX didn't found the libraries ? I have try to copy the librairies in /usr/lib and /usr/lib/opendbx but with no results. In the Resources subdirectory, I have created a symbolic link to /usr/local/lib/libopendbx.dylib but without progress. ln -s /usr/local/lib/libopendbx.dylib opendbx I get the same error :-( If i modify the info.plist file to set the SqueakDebug key at 1 and the SqueakPluginsBuiltInOrLocalOnly key at false, I can see the search of librairies by the SqueakVM. The SqueakVM doesn't seem to try to load the openddbx libraries. You can download the log file at http://www.auverlot.fr/squeakdbx/squeakdbx.txt My previous tests under Linux have worked fine but i didn't find a solution with Mac OS X. Someone has an idea for help me ??? Thanks for your help. Best regards Olivier www.auverlot.fr

Re: [Pharo-project] paragraph replacement?

That is why I asked if someone knows how should the method behave. In older images (1.2), there is an #actOnClickFor: on the TextAction Hierarchy. TextDoit does for example: actOnClickFor: anObject "Note: evalString gets evaluated IN THE CONTEXT OF anObject -- meaning that self and all instVars are accessible" Compiler evaluate: evalString for: anObject logged: false. ^ true It seems the interface was extended to send the editor instance and the paragraph to the Link, so that a link could e.g. change what is displayed. What kind of TextAction do you have? You could just implement there whatever action makes sense (ignoring the editor and paragraph parameter and do exactly what #actOnClickFor: did in the old ST80 Paragraph). The whole TextAction stuff needs a pass... maybe with Moose as a Client, we can do that pass... Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

[Pharo-project] Linking Update Mails to issue tracker
by Torsten Bergmann May 23, 2011

May 23, 2011

Dear Santa, These days I find myself constantly copying and pasting issue numbers to find out the details of a new Pharo update. If it is not too complicated/cumbersome I would like to see the following: When a mail on a new Pharo update is generated/written would it be possible to add not only the issue number and short text but also the issue URL so it links to the issue tracker? So mails in the archive like this http://lists.gforge.inria.fr/pipermail/pharo-project/2011-May/049373.html would directly link to issues like http://code.google.com/p/pharo/issues/detail?id=4257 and one can easily click to find out what the change really is about...

ScaledDecimal would be used where consistency is often more important than accuracy, e.g. in Financial calculations where being off by a few pennies doesn't matter but always getting the same answer matters a LOT. Once a number is converted to a ScaledDecimal computations must always produce the same result assuming enough digits. To ensure this asScaledDecimal must produce a scaled decimal for use in computations and, as such, storing a fraction internally is unacceptable. >From a financial point of view 1/3 * 3 is not 1! >From a programmers point of view asScaledDecimal changes the value in much the same way asInteger does for a float. Having said all of this allow me to contradict myself. It seems to me that a scaled decimal should in general store more digits than are displayed. For example money might be stored with a large (possibly arbitrary) number of digits after the decimal point but only display two digits beyond the decimal point. I don't know how ScaledDecimal is implemented but I would be inclined to use arbitrary or large size integers and store the location of the decimal point internally recomputing the position of the decimal point after each calculation. This is an expensive way of doing computations but I expect users of ScaledDecimal can live with that. When converting non decimal results to ScaledDecimal then how many digits of precision to maintain must be specified somehow. Dealing with ScaledDecimal is a complicated matter and I have probably failed to appreciate many of the complications but whoever is implementing ScaledDecimal (and Smalltalk needs ScaledDecimal) needs to appreciate those complications. Anybody here a financial expert? Ralph Boland

This method is also missing from Pharo 1.2. Anyone knows where to get it from? No idea.. what is it supposed to do? Having two Paragraph implementations in parallel over so many years was not a good idea... Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

[Pharo-project] Complete MethodContext stack for testing
by Mariano Martinez Peck May 23, 2011

May 23, 2011

Hi guys. We need to do some test to serialize a MethodContext to a file, materialize it, and then compare it to the original. One of the problems we face is that some values in the MethodContext are changed so it is difficult to test. So...what we would like is to get a "bottom" MethodContext that we can ask #sender, and to that one #sender, and like that....and the whole stack should cannot be changed. Another problem is that I cannot do a #deepCopy on a MethodContext because #basicNew: throws errror. Is this possible? Thanks in advance, -- Mariano http://marianopeck.wordpress.com
