by Roelof Wobben March 27, 2019

March 27, 2019

Hello, I have a SortedCollection of teams. Now I need to convert this to a line like this : 'Allegoric AlaskansÂ Â Â Â Â Â Â Â Â Â Â Â |Â 1 |Â 1 |Â 0 |Â 0 |Â 3' I tried it with this : outcome := Array Â Â Â Â Â Â streamContents: [ :s | Â Â Â Â Â Â Â Â Â TeamStatusSorted Â Â Â Â Â Â Â Â Â Â Â Â do: [ :each | Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â s << each name. Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â s << String cr ] ]. Â Â Â ^ outcome or String streamContents but it will not give me the right answer, So please some hints how I can make this work. Roelof

More info & examples on MAAdaptiveModel ?
by Albrecht Baur March 27, 2019

March 27, 2019

Hi all, I am looking for more info or usage examples of MAAdaptiveModel. So far I found the following good resources: * The masters thesis of Lukas Renggli and the impl. of Pier: http://sdmeta.gforge.inria.fr/Teaching/Lille/0910-MetaModelisation/Magritte… * In the package Magritte-Tests-Model: The test MAAdaptiveModelTest Could someone point me to more resources on MAAdaptiveModel if there are any? Especially the topic searching / building search indexes on MAAdaptiveModel data stored e.g. in mongodb as voyage root would be helpful. -> How is the performance when searching on MAAdaptiveModel values with and without index ? Hints would be nice! Albrecht

What oo/modelling books/articles do we recommend these days?
by Tim Mackinnon March 26, 2019

March 26, 2019

As I see Exercism students grapple with more realistic problems which are less algorithmic and more potentially OO (in this case - https://github.com/exercism/pharo-smalltalk/blob/master/dev/src/Exercism/To… <https://github.com/exercism/pharo-smalltalk/blob/master/dev/src/Exercism/To…> ), I am wondering what we point people towards to learn about OO, identifying objects and more importantly responsibilities these days? There is the early Beck CRC paper - but looking at it again, I wonder if its a bit cursory for people who missed the whole OO discovery years ago, and are now faced with competing advice on how to write good programs (much of which seems to eschew OO these days - rather unfairly I think). Any good references come to mind? As Iâll build up a list that I can point people to, that hopefully puts them in a better place to solve these more interesting and hopefully rewarding problems.

Re: [Pharo-users] ZnURL and parsing URL with diacritics

Special Issue on Smalltalk Technologies

Special Issue on Smalltalk Technologies https://www.journals.elsevier.com/science-of-computer-programming <https://www.journals.elsevier.com/science-of-computer-programming> Guest Editors: LoÃ¯c Lagadec (Coordinator) Ensta Bretagne, Lab-STICC Anne Etien UniversitÃ© de Lille, CRIStAL, UMR9189 Jannik Laval UniversitÃ© LumiÃ¨re Lyon 2, DISP, EA 4570 Theme Smalltalk is an exciting objectâoriented language in which even primitive values are uniformly handled as normal objects, described by classes that one can browse, inspect and extend. Smalltalk was born during the seventies, still the ideas behind the currently available implementations are often at the edge of innovation. Smalltalk benefits from being a highly expressive language in which complex and powerful systems can emerge from the composition of simple building blocks. Thanks to its dynamic nature, fast prototyping and agile software development are made possible. Smalltalk is not only a simple and pure dynamic object-oriented language, but is also a programmable system with processes, its own user interface and a complete Interactive Development Environment (IDE). Smalltalk is a reflexive system, with all its elements being implemented in Smalltalk, which benefits from powerful metaâprogramming facilities. This means that elements can be extended, customized or adapted according to particular contexts, that the Smalltalk IDE itself can be used to implement, validate and debug the Smalltalk system extensions, and that a program is able to query and to change its own structure and behaviour. In this context, the research topics that relate to Smalltalk technologies are large, and need to receive more attention and research effort, considering that Smalltalk has established itself as a test bed for software engineering theories and tools. TOPICS include: ï§ Aspect-oriented programming, ï§ Design patterns, ï§ Experience reports, ï§ Frameworks, ï§ Implementation, new dialects or languages implemented in Smalltalk, ï§ Interaction with other languages, ï§ Meta-programming and Meta-modelling, ï§ Tools Important Dates: â¢ Apr. 30, 2019 Full paper submission due â¢ Aug.31, 2019 Paper acceptance decision â¢ Sep.15, 2019 Camera-ready paper due

eval from the linux commandline

March 25, 2019

i need to eval an object from my linux commandline. I understand that clap-st is able to do this, but I can't seem to import it into pharo7, I suppose because of compatability reasons. Someone sent me this, but I can't seem to replicate the help screen. Is it because I'm on linux and he's on mac? prometheus:2018-12-20 sven$ ./pharo Pharo.image printVersion [version] 'Pharo7.0.0' 'Pharo-7.0.0+rc1.build.66.sha.0ff3a6c1c0f1d9b2876c50e19b790dd7bb926dd9 (64 Bit)' prometheus:2018-12-20 sven$ ./pharo Pharo.image --list Currently installed Command Line Handlers: loadHermes Loads the hermes files passed as parameter printVersion Print image version save Rename the image and changes file initializePackages Initialize packages and protocols from a given lists st Loads and executes .st source files config Install and inspect Metacello Configurations from the command line metacello Install and inspect Metacello Baselines/Configurations from the command line test A command line test runner Fuel Loads fuel files clean Run image cleanup get Install catalog projects from the command line (consult catalog at http://catalog.pharo.org) perform Perform given message on a specified class or global eval Directly evaluates passed in one line scripts
