Hi, I just got the following update from Philippe: This is cool. But we should create actual groups for both the Pharo Consortium and Pharo Association on LinkedIn. It should be like a badge that you're proud to wear. Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

Re: [Pharo-project] Collect all references to AnObsoleteFoo
by Fernando Olivero April 2, 2013

April 2, 2013

Ciao Roberto, Whenever you remove a class that is still referenced in the system, an ObsoleteClass takes the place of the removed class. In the late-bound spirit of Smalltalk, the system allows removing the classes and dealing with the current references later. If i may question the source of your problem: "a Dictionary (containing receivers of method calls, i.e., classes) that I need to serialize in a file (i.e., using Fuel)", are you sure you need to serialize the actual classes? or just the names? or even a description of the class within Ring? Think about what you are modeling with a Dictionary that holds <messages,set of receivers>, and maybe try to reify that concept.

[Pharo-project] Modern and Future Smalltalk
by Dennis Schetinin April 2, 2013

April 2, 2013

Hello, I'm preparing a report for a small local conference on the "Internet Technologies". I would like to present some current Smalltalk trends in this area. First of all, I'm thinking of Pharo efforts in conjunction web frameworks like Seaside, AIDA/Web, Illiad. Certainly I'll talk about Amber and hopefully there'll be a special report on it. I'll mention GemStone. What else should I talk about? -- Best regards, Dennis Schetinin

Re: [Pharo-project] PDF Rendering
by Christian Haider April 1, 2013

April 1, 2013

Hi Ben, yes I am lurking :-) About manipulating PDFs - this is really easy and people have done that: Aik-Siong Koh needed to split large PDFs into one-page PDFs and Holger Kleinsorgen answered on vwnc with the following code to do that: | inputStream inputPDF pageNumber | inputStream := 'ReleaseNotes7.7.pdf' asFilename readStream binary. [ inputPDF := PDF.File readFrom: inputStream. pageNumber := 1. inputPDF trailer Root pagesDo: [ : page | | targetFilename onePageDocument | onePageDocument := PDF.Document new. onePageDocument root addPage: page. targetFilename := (pageNumber printString, '.pdf') asFilename. onePageDocument saveAs: targetFilename. pageNumber := pageNumber + 1. ]. ] ensure: [ inputStream close ]. Bob Nemec (Author of Report4PDF) needed to add a document to another. The how-to is on the docs wiki: http://www.freelists.org/post/pdf4st/Append-another-PDF-document Lately, I had to put a chart onto an existing PDF page which contained background (with shadows which I cannot do yet) and I was surprised myself how easy that was (just add another content stream to the existing one). All this is nice and easy, because PDF is so well structured - I love it :-) Cheers, Christian > -----UrsprÃ¼ngliche Nachricht----- > Von: pharo-project-bounces(a)lists.gforge.inria.fr [mailto:pharo-project- > bounces(a)lists.gforge.inria.fr] Im Auftrag von Ben Coman > Gesendet: Sonntag, 31.
