Re: [Pharo-users] GSOC 2016 Application update

by PBKResearch

Alexandre I would strongly disagree with your first proposed change. In my understanding (English is my native language), 'popularity' is a mass noun, not countable, hence the 'an' is incorrect. Wiktionary, based on an ancient edition of Webster, allows the possibility of countable use, but the only example it quotes is archaic. At the very least, there is nothing wrong with the original version.

Re: [Pharo-users] [Pharo-dev] What are immediate subclass and word variable subclass?

Immediates are objects that are stored in an object pointer using a tag to distinguish them from ordinary object pointers. In v3 the only immediate is SmallInteger. In 32-but spur there are SmallInteger and Character. An implication of this is that in spur all Characters can be compared using #==. In 64-bit Spur there is also SmallFloat64. If a float's exponent is in the middle 8-bits of the 11-bit exponent range then it will be immediate. If a float's exponent is outside of the middle 8-bits it will be boxed. Objects on the heap are either pointers or bits. For example instances of Point, Array, BlockClosure etc are pointer objects. But Bitmap, ByteString, WideString etc are bits objects. In v3 bits objects are either a sequence of bytes (ByteArray, ByteString, ByteSymbol etc) or 32-bit words (WideString, Float, Bitmap etc). Spur supports byte, short, word and double-word bits objects even though currently only byte and word classes exist. 16-bit strings will be useful on Windows, for example.

Re: [Pharo-users] [ANN] OSUnix and OSLinuxUbuntu on new UFFI

by Sebastian Heidbrink

Hi, I don't want to spoil the great news, but actually the most recent changes break Pharo 5.0 with SpurVM on Windows 8. UFFI must have brought something in there that makes Pharo crash. Windows 8 users should be adviced to keep their current working images. I am lost since a few days since I can't built a new image that would actually work. I tried several older snapshots of the VM and the Pharo images listed in the PharoLauncher but none work.

[ANN] OSUnix and OSLinuxUbuntu on new UFFI

by Torsten Bergmann

These two projects (who were based on NativeBoost in Pharo 4) are now updated to new UFFI in Pharo 5 which means they are loadable in recent Pharo 5 image and all tests pass. So if you are working on Linux/Unix you might wan to check them out in latest Pharo 5 by loading them from Catalog browser. A BIG THANKS to Esteban for helping me in the conversion and updating the new Unified FFI (UFFI) according to the issues that were found during the conversion. More is in the pipe ... step by step it goes! Bye T.
