Hi guys, Can anyone please quickly explain to me the difference between (1) an instance variable defined on the class side and (2) a class variable defined on the instance side? Thanks a lot! Cheers, Roberto

Are there lazy quantifiers in Pharo's Regex implementation ?
by Paul DeBruicker Jan. 8, 2015

Jan. 8, 2015

I can see and use the "{1,3}" quantifiers but are there lazy quantifiers too? e.g. http://msdn.microsoft.com/en-us/library/3206d374(v=vs.110).aspx It seems like the "?" is parsed as a lookahead or as an optional element. Attempting to use it as a lazy quantifier gives an error.

Fuel and multiple bytecode set support
by ClÃ©ment Bera Jan. 8, 2015

Jan. 8, 2015

Hello, As some of you may know, Pharo is being enhanced with support for multiple bytecode sets. This will allow to run at the same time compiled methods with 2 different bytecode sets for experimentation and to add easily the new bytecode set described in this ESUG paper <http://esug.org/data/ESUG2014/IWST/Papers/iwst2014_A%20bytecode%20set%20for…> . The virtual machine knows which bytecode set the compiled method uses for its encoding based on the sign of its header. This means that on the contrary to right now, a compiled method *can* have a negative header. The issue is that typically operations such as #bitAnd: or #+ to access bits of the smallinteger does not work the same way on negative integers (2 complement's implementation of integers), resulting in incorrect values. I am fixing the problematic cases in Pharo. One case is in Fuel and I can't fix it myself. It's in: FLCompiledMethodCluster>>#serializeInstance: aCompiledMethodToSerialize with: anEncoder "some code" header := aCompiledMethod header. "some code" anEncoder *encodeUint32*: header "some code" This looks problematic because now header is not a uint anymore but a sint. In addition, #encodeUint32: uses #bitAnd: which may work differently on negative integers. What do you fuel experts think ? Is there anything to fix there ? Best, Clement

SmalltalkHub bugs & hangs :-(
by Noury Bouraqadi Jan. 7, 2015

Jan. 7, 2015

SmalltalkHub is slow, so donât click too fast :-( While Iâm grateful to developers of SmalltalkHub and previously SqueakSource, I believe as a small community, we cannot afford developing everything by ourselves. We donât have enough man-power. We can see the symptoms since SmalltalkHub is in beta stage since way too long... Itâs better to use some mainstream platform such as github. Weâll we have support for it in Pharo 4? It would be interesting also from the communication point of view to make the world a little bit more aware of Pharo. Noury

by Torsten Bergmann Jan. 7, 2015

Jan. 7, 2015

Need an easy way to convert HTML into PDF for printing? The project http://wkhtmltopdf.org can help you here. If you want to use it from Pharo just check out: http://smalltalkhub.com/#!/~TorstenBergmann/WKHTML2PDF This project allows you to easily use the library. First select the engine: HTML2PDFConverter useExecutable. or HTML2PDFConverter useLibrary. and then convert: HTML2PDFConverter convert: 'http://www.pharo.org' toFile: 'pharo.pdf' to get a printable version of the Pharo homepage. As ever docu is on the STHub project website. It uses NativeBoost to call the library and OSProcess to call the executable. Bye T.

Re: [Pharo-dev] [Pharo-users] Question about loading Roassal2 in Pharo4

I would prefer to have the integration work automatically without any trigger, but I do not know how to fit this in the current Pharo integration process.
