Re: [Pharo-project] Notification on unloading of packages?

[Pharo-project] Collect all references to AnObsoleteFoo

by roberto.minelli＠usi.ch

Hi, I'm getting crazy about obsolete behaviors and any help here is really appreciated. In a nutshell, I have a Dictionary (containing receivers of method calls, i.e., classes) that I need to serialize in a file (i.e., using Fuel). Fuel returns an error in FLGlobalClassCluster>>#serializeGlobalClass:on: complaining that I'm trying to serialize an obsolete class. Now my question is, apart from executing this small piece of code... SmalltalkImage current fixObsoleteReferences. SystemNavigation new obsoleteBehaviors size > 0 ifTrue: [ SystemNavigation new obsoleteBehaviors inspect.] â¦in which I discovered to have many obsolete references, how can I "browse" and eventually kill such references? For me the entire "behavior" of obsolete classes is obscure and I don't know how those classes are originated. More important, I also don't know how to eliminate them. Thanks in advance, Roberto

Hi Dennis, For the web you can look at my ESUG presentation: On the Web Frontiers with Smalltalk http://ftp.eranova.si/aida/mivsek-web-frontiers-esug11.pdf Here you can find current trends of Smalltalk on the web: HTML5, real-time web, client-side web apps, mobile, revival of MVC pattern, what are the challenges, how Smalltalkers are prepared for them, etc. Hope this helps a bit Janko Dne 01. 04. 2013 05:43, piÅ¡e Dennis Schetinin: > Hello, > > I'm preparing a report for a small local conference on the "Internet > Technologies".

Re: [Pharo-project] PDF Rendering

by Christian Haider

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.
