DateAndTime>>offset: returns different instant
by Jakob Reschke 22 Oct '16

22 Oct '16

Hi all, the comment in DateAndTime>>offset: reads: > Answer a <DateAndTime> equivalent to the receiver but with its local time > being offset from UTC by offset. But the result of #offset: does not represent the same instant of time: dt := DateAndTime now. dt " 2016-10-22T22:18:12.003779+02:00" dt offset: 3 hours " 2016-10-22T22:18:12.003779+03:00" dt = (dt offset: 3 hours) "false" In Pharo, things behave differently: dt := DateAndTime now. "2016-10-22T22:21:07.097583+02:00" dt offset: 3 hours. "2016-10-22T23:21:07.097583+03:00" dt = (dt offset: 3 hours) "true" ...thus portability is broken. Looks like #utcOffset: does what #offset: seemed to promise in my understanding: dt = (dt utcOffset: 3 hours) "true" So, in my effort of porting some code from Pharo to Squeak, I have to replace offset: by utcOffset:. Is the comment in #offset: inaccurate, or did I misunderstand it? Would you agree that a clarification would be helpful? Was DateAndTime handling ever portable? Best regards, Jakob

Xtreams: Debugging Grammars
by Chris Cunnington 21 Oct '16

21 Oct '16

>When I evaluate: > parser := PEGParser parserPEG parse: 'Grammar' stream: PEGParser grammarEmailAddress actor: PEGParserParser new. >I get: KeyNotFound: key 'quotedstring' not found in Dictionary >How am I supposed to debug that to find the typo in my giant string above?! Hi Sean, Your error is saying is that there is no key called 'quotedstring' in the dictionary in the grammar ivar of your parser. In each parser is a grammar ivar. It contains a dictionary. The values of the dictionary are graphs of compiled blocks. Each node of the graph is a block with arguments that are blocks that have arguments that are blocks, etc. It's a graph of compiled blocks. Try this. Add in PEGParser class. grammar3Names " a grammar to create a parser to sort three names as per page 24 of Grune's book Parsing Techniques (1990)" ^'Sentence <- NAME NAME <- "tom" / "dick" / "harry" ' Now execute this. (PEGParser parserBootstrap) parse: 'Grammar' stream: PEGParser grammar3Names reading actor: PEGParserGenerator new. That will show you the code that will create the dictionary in the grammar ivar. Now make a change. myparser := (PEGParser parserBootstrap) parse: 'Grammar' stream: PEGParser grammar3Names reading actor: PEGParserParser new. You generated the parser, not the code for the parser. To use the parser. myparser parse: 'Sentence' stream: 'harry' reading actor: nil Now let's look at the same thing in three ways. PEGParser>>#grammarPEG this is the grammar PEGParser>>#parserBootstrap this is the code generated by the PEGParserGenerator from grammarPEG PEGParser>>#parserPEG this is the parser returned by PEGParserParser from grammarPEG You will see that PEGParser parserBootstrap and PEGParser parserPEG are interchangeable anywhere. In fact, if the goal is to populate the grammar ivar with a dictionary to make a parser, then #parserPEG starts to grate on one's nerves, because you already have what you need in the grammar ivar by evaluating PEGParser parserBootstrap. #parserPEG compiles the grammarPEG using PEGParserParser into the grammar ivar to make a parser, but it's the exact same as what was already there. It's irritating. I'll release some examples in a package called Xtreamly some time before Christmas to help start understanding Xtreams-Parsing. HTH, Chris

The defaullt implementation of isEmpty might do too much work
by Nicolas Cellier 21 Oct '16

21 Oct '16

The default behavior is to rely on ^self size = 0. But default size is doing too much (it iterates over all elements). It's OK for most of our classes which know very well about their size and override #size. It's not OK for an eventually lazy or infinite subclass. I realized this by answering http://stackoverflow.com/questions/40149826/is-there-a-construct-like-itera…

<Programming> 2017: Call for papers
by Tim Molderez 21 Oct '16

21 Oct '16

<Programming> 2017 : The Art, Science, and Engineering of Programming April 3-6, 2017, Brussels, Belgium http://2017.programming-conference.org We started a new conference and journal focused on everything to do with programming, including the experience of programming. We call the conference <Programming> for short. Paper submissions and publications are handled by the journal. Accepted papers must be presented at the conference. ******************************************************** CALL FOR PAPERS ******************************************************** <Programming> 2017 accept scholarly papers including essays that advance the knowledge of programming. Almost anything about programming is in scope, but in each case there should be a clear relevance to the act and experience of programming. PAPER SUBMISSIONS: December 1, 2016 We accept submissions covering several areas of expertise. These areas include, but are not limited to: • General-purpose programming • Distributed systems programming • Parallel and multi-core programming • Graphics and GPU programming • Security programming • User interface programming • Database programming • Visual and live programming • Data mining and machine learning programming • Interpreters, virtual machines and compilers • Modularity and separation of concerns • Model-based development • Metaprogramming and reflection • Testing and debugging • Program verification • Programming education • Programming environments • Social coding ******************************************************** CALL FOR WORKSHOP PROPOSALS ******************************************************** To build a community and to foster an environment where participants can exchange ideas and experiences related to practical software development, ‹Programming› will host a number of workshops, during the days before the main conference. The workshops will provide a collaborative forum to exchange recent and/or preliminary results, to conduct intensive discussions on a particular topic, or to coordinate efforts between representatives of a technical community. They are intended as a forum for lively discussion of innovative ideas, recent progress, or practical experience on programming and applied software development in general for specific aspects, specific problems, or domain-specific needs. We also encourage practical, hands-on workshops in which participants actually experience one or several aspects of practical software development. WORKSHOP PROPOSAL SUBMISSIONS: November 15, 2016 The duration of workshops is in general one day, but we encourage the submission of half-day workshop proposals on focused topics as well. In exceptional situations, e.g., for workshops that involve actual practice of programming-related activities, workshop organizers can request a 2 day workshop slot. If desired, the workshop proceedings can be published in the ACM Digital Library. ******************************************************** IMPORTANT DATES ******************************************************** Research paper submissions: December 1, 2016 Research paper first notifications: February 1, 2017 Research paper final notifications: March 7, 2017 Workshop proposals: November 15, 2016 PX 2017 workshop submissions: January 15, 2017 Poster abstract submissions: January 16, 2017 ******************************************************** ORGANIZATION ******************************************************** General Chair: Theo D'Hondt, Vrije Universiteit Brussel Local Organizing Chair: Wolfgang De Meuter, Vrije Universiteit Brussel Program Chair: Crista V.

Re: [squeak-dev] The Trunk: Kernel-nice.1039.mcz
by Eliot Miranda 21 Oct '16

Nicolas, I thought that there had been a conversation about this and that Bert had expressed a preference for DoubleByte and DoubleWord. Hence I kept to that. If I'm mistaken forgive me. But personally I don't like HalfWord. t's as ambiguous as word. At least DoubleByte is not ambiguous.
