marcus may be we should slowly deprecated ast into cachedParseTree or something like that. Le 30/4/16 Ã 22:25, Sean P. DeNigris a Ã©crit : > Why does CompiledMethod understand both?

Re: [Pharo-users] Machine learning in Pharo

Hello, I added a "MachineLearning" repository to Smalltalkhub a while back, but I got sidetracked before adding anything beyond a naive KNN classifier, which was really just to help prototype the testing framework. That said, my plans involve expanding the library extensively this summer in conjunction with my research, starting in about 6 days. I work on natural language processing, so it is possible that I was already planning to build some of the models you were intending to use. What models were you looking for? I also added a parallel NLP repository, which is similarly barren but for a naive IBM Model 1 translation model, which probably won't help you. Relatedly, I was contemplating building an RSS classifier myself, and would gladly use one, were it to exist.

Re: [Pharo-users] RT export to PDF

The PDF exporter has its last updates in november, so might be slightly out of date. When comparing RTSVGVisitor2 to RTPDFVisitor, I notice some missing visitors. AFAIK, Artefact has limited bitmap support at the moment, and uses the JPEGReadWriter instead of embedding directly. http://forum.world.st/PNG-in-Artefact-td4798885.html You need to add something like RTPDFVisitor>>visitBitMapShape: aBitmapShape | s | s := WriteStream on: ByteArray new. TRPlatform current pngReadWriterClass putForm: (aBitmapShape form) onStream: s. page add: (PDFPngElement from: aBitmapShape encompassingRectangle topLeft x mm @ aBitmapShape encompassingRectangle topLeft y mm dimension: aBitmapShape width mm @ aBitmapShape height mm fromStream: s contents readStream) Stephan
