[Pharo-project] Special Objects Array question
by Gabriel HernÃ¡n Barbuto Nov. 2, 2010

Nov. 2, 2010

Hi I am looking at MicroSqueak and trying to make it work in a new image. I run MicroSqueak in a new VM and it works. What is a bit odd is that MicroSqueak has a different class hierarchy for String. It doesn't know about ByteString nor WideString and the String class in MicroSqueak has a different format than the one in recent images. How is it possible that a MicroSqueak generated image runs on the recent VMs? The special objects array that MicroSqueak creates is different. For example, at index 7 MicroSqueak put its own version of String instead of ByteString. I have tried it on Mac OS X on the Squeak 4.2.5b1 VM and on Windows on the 4.0.2 VM. My guess is that it works because MicroSqueak String has the same structure as ByteString in current images. So the VM does not notice that it is working with a different object. Thanks Gabriel

Re: [Pharo-project] Issue 3202:references in System->Settings should refer to 'action click' menu instead of 'yellow button' menu
by Sheridan Mahoney Nov. 2, 2010

Nov. 2, 2010

This bug report comes in reference to the turning on of morphic halos. System->Settings->Appearance->Morphic->Halo->Show default yellow button menu should instead refer to: System->Settings->Appearance->Morphic->Halo->Show default action-click menu This is perhaps an issue of changes in terminology in the book 'Pharo By Example' having repercussions in Pharo System->Settings terminology, so it could be a known issue (although I didn't find a bug report). It looks like the Settings menu may have multiple references to the older terminology, using for example 'yellow button' instead of 'action-click'. Pharo image: dev Pharo core version: Pharo-1.1.1-- Latest update: #1141 Virtual machine used: 4.0.3.2202 Unix VM OS: Ubuntu Lucid Lynx 10.04 Class browser used if applicable: SystemBrowser default Steps to reproduce: 1. From the World menu open System->Settings->Appearance->Morphic->Halo->Show default yellow button menu

The best thing to do is to make the mailing list enforce trimming and quote- to original text fraction and reject top- and bottom-posts. It tends to have a very good effect on readability of the list especially when looking back a few months/years later. Stephan

[Pharo-project] Writing API for XML (WAX) - Bibliography example
by Hannes Hirzel Nov. 1, 2010

Nov. 1, 2010

Hello I read the post by Stephane Ducasse about writing XML (see below) with a bibliography example. Recently I (re)-discovered the port to Squeak/Pharo of the Writing API for XML (WAX) (http://java.ociweb.com/mark/programming/WAX.html) and could put it to good use for writing an XML file a bit more complex than the bibliography example. >From the web site WAX has the following characteristics: * focuses on writing XML, not reading it * requires less code than other approaches * uses less memory than other approaches (because it outputs XML as each method is called rather than storing it in a DOM-like structure and outputting it later) * writes all XML node types * always outputs well-formed XML or throws an exception unless running in "trust me" mode * knows how to associate DTDs, XML Schemas and XSLT stylesheets with the XML it outputs * is well-suited for writing XML request and response messages for REST-based and SOAP-based services However I do not know how far these points apply to the Squeak/Pharo port. http://www.squeaksource.com/WAX It needs the VB Regex package (http://www.squeaksource.com/Regex) As an exercise I did the code to produce the example Stephane gave. It worked fine; see below.

The biggest problem is that huge testsuites spend all their time searching the image for pragmas when printing the TestSuite.
