The "death" of Smalltalk
by J.F. Rick Jan. 12, 2015

Jan. 12, 2015

Hi everyone, I just watched https://www.youtube.com/watch?v=YX3iRjKj7C0 and had a few comments that I thought I would share. First, there is a real opportunity for Smalltalk to come back in the guise of Pharo. Steph and Marcus are doing a great job providing leadership towards that end and the community is great. Second, we need to be careful in spreading the word. Slowly but surely (the current Pharo approach) is a great approach as it allows really building something worth spreading before trying to get everyone into it. If it spreads too quickly, bad API or immature toolkits will become ingrained and flaws will be apparent. The books, websites, etc. are really good things to get right before trying to get others into it; they are already very good. Third, if you want to really spread Smalltalk, then the fundamentals that newcomers experience need to be without obvious flaws. From personal experience, I can tell you that BitBlt rendering makes newbies think that Pharo is a toy language. Switching to Athens rendering is therefore tremendously important for adoption. Package management really needs to be cleaned up. There needs to be a simple way to merge resources (bitmaps, audio, external files) into the codebase. Simple audio needs to work on all platforms. This may seem trivial but audio is one of the simplest things that newcomers want to do. >From a Linux perspective, this will probably necessitate switching to a 64-bit VM as the 32-bit sound plug-ins are a giant pain. Given that even phone OSs are switching to 64-bit, there may not be a need for a 32-bit Pharo. Of course, much of this is already on the horizon. As the new year begins, I'll once again be coding in Pharo and look forward to it. I'm really hopeful about the future.

Can I get write access to PharoExtras > ImageWorker ? I have a fix to make tests work when there is a space in the path to the VM. https://pharo.fogbugz.com/default.asp?14707 cheers -ben

Jpeg doesn't have transparency. For browsers there is a hack. http://jim.studt.net/jpeg-alpha/ http://stackoverflow.com/questions/14220221/how-to-insert-transparent-png-i… PDF supports transparency since PDF 1.4 To avoid trouble, only use images with the same color space and either a 1 bit mask or a clipping path. Composing images in different color spaces with an alpha channel seems to be difficult to get right. Stephan

PNG in Artefact
by olivier auverlot Jan. 11, 2015

I improved Artefact this morning and added the support for PNG files. It's now possible to use PDFPngElement to include a PNG (untransparent) in a PDF file produced by Artefact. https://sites.google.com/site/artefactpdf/ Best regards Olivier ;-)

CI nesting of XMLWriter >> writeWith:
by Ben Coman Jan. 11, 2015

Jan. 11, 2015

I am having a look at some failing tests for CIXMLPublisherTest. This uses XMLWriter, which I haven't used before, so I'm looking for confirmation of the semantics I've guessed for #writeWith:. It seems that #writeWith: should not be nested. Since... xmlWriter := XMLWriter new. xmlWriter writeWith: [ :writer | writer tag: 'report' with: [ writer tag: 'name' with: 'TestName - Report'. xmlWriter writeWith: [ :writer2 | writer2 tag: 'finality' with: 'succeed' ] ] ] ...produces an error "CollectionIsEmpty: an OrderedCollection() is empty" This pattern is the cause of 4 of the 8 tests for CIXMLPublisherTest to fail. In this case CIXMLPublisher >> publishValidationResult: does a #writeWith: then calls #publishSuccess: which does another #writeWith: . That example was done on top of... $ wget https://ci.inria.fr/pharo/job/Pharo-4.0-Issue-Tracker-Image/736/artifact/Ph… $ unzip *zip $ wget --quiet -O - get.pharo.org/vmLatest | bash $ ./pharo-ui *.image I have logged https://pharo.fogbugz.com/default.asp?14708 cheers -ben
