Re: [Pharo-users] Wiring objects, IoC and Service Locator

by aryehof

In SmallTalk:- 1. Blocks (i.e. anonymous functions) means that one needs not necessarily implement a /Class/ (MovieFinder), in order to vary alternative behavior, unlike Java (before 8). 2. If one does want a number of "finders" (as Classes), then one will typically see one "injected" (constructor or method injection), where each understands some common "find" message. Is the real question for 2 above, "what (or who) decides" which will be injected? -- View this message in context: http://forum.world.st/Wiring-objects-IoC-and-Service-Locator-tp4949280p4950… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] [Modeling with Pharo] How to model a simple human interaction.

by aryehof

Your using an object-oriented language, why not use an object /domain model/? Consider that Kristen Nygaard stated that an object-oriented "program execution is regarded as a physical model, simulating the behavior of either a real or imaginary part of the world." By physical model, he really is meaning a "direct model" where you /directly /represent the concepts of your problem domain as objects that interact with each other. Sure, you could use a state machine, but why build a model (your domain problem) on top of a model (a state machine) using a paradigm intended to support a different way. State machines are a favored way to model process and state in functional programming. A domain model would separate the user interaction from your domain problem itself. You would model an Order that knows a User and one or more Images. Anyway, hopefully some food for thought. -- Aryeh -- View this message in context: http://forum.world.st/Modeling-with-Pharo-How-to-model-a-simple-human-inter… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] crash.dmp of OSSubProcess on Pharo 6.0

by john pfersich

That VM is (was) a 6.0 alpha. I tried to update and got this: jpfersich@ubuntu64-001:~/pharo64-6.0$ curl get.pharo.org/64 | bash % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 232 100 232 0 0 581 0 --:--:-- --:--:-- --:--:-- 582 bash: line 1: syntax error near unexpected token `newline' bash: line 1: `<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">' Then I tried the Custom installs, downloaded pharo64-linux-threaded-stable.zip and sources.zip and when I tried to run it, I got 'Pharo cannot locate the sources file named /home/jpfersich/pharo64-6.0/pharo-vm/lib/pharo/5.0-201705310241/PharoV50.sources. The sources file I downloaded is PharoV60.sources. So I finally did curl get.pharo.org/64/stable | bash and curl get.pharo.org/64/vmT60 | bash and got a usable system.

Mariano, yes I was using the 64 bit pharo. I downloaded the 32 bit pharo 6.0 and it works just fine. Thanks.
