Re: [Pharo-users] How to recover selections in a fastlist after an update

by Steven Costiou

Hi Ben, sure. This is my browser entry point: adaptationsBrowser | browser | browser := GLMTabulator new. browser row: [ :r | r column: #adaptations; column: #objects; column: #methods ]. browser row: #diff. browser transmit to: #adaptations; andShow: [ :a :adaptations | self adaptations: adaptations in: a ]. ^ browser adaptations: adaptations in: composite | list | list := composite fastList. list title: 'Adaptations'. list display: adaptations. adaptationsList := list. So my problem is that this adaptation list may change overtime. So periodically the #step method is called, the adaptation collection is updated and i also call #update to refresh the browser. However, if an adaptation was selected in the list, then calling #update will reset this selection.

Re: [Pharo-users] Namespaces (was Re: Behold Pharo: The Modern Smalltalk)

by Dimitris Chloupis

I am against the very idea of special syntax. Even python uses special syntax as nothing more than syntactic sugar to make the code more readable from the point of view of not everything looking the same. I agree with the concept of everything being an Object. I also dont like the idea that we tend to not have a clear cut border between the IDE and the language/library. Of course I think IDE functionality as much as namespaces is concerned (within the borders of my understanding) is essential. But should be seperate and the IDE act mostly as a visualisation tool and automation tool. My problem , is that the Pharo operates on a global space , so lets say i do what I said above I still dont avoid name collisions. Because MyInstance outside MyModule should diffirent from MyInstance inside MyModule. It could become possible by masking the names from the user. So that there is no conflict between MyModule MyInstance and MyModule2 MyInstance unless you introduce of couse similar to python the optional feature of collapsing the scope. We already have Packages which tie in with Metacello, so I was think about Modules or however we want to call them as a layer between. I am fine with metacello personally. Its the name collisions that only concerns me and not forcing me to use unique names. Of course a module can contain other modules. I know how to do this for my projects , I would manipulate the IDE into displaying Modules as a seperate row in System Browswer , Packages will continue being the the up most container. And for name of a class I would add the name of the Module to the class , if I wanted to keep supporting the existing enviroment , but hack it so it appears to the user as 2 seperate things so for user will see MyModule MyInsance myMessage: but it Would be for the system MyModuleMyInstance myMessage: which would make sense from naming persepctive even to an outsider not using the module system and would not require for him to install the modue library and essentially MyModule MyInstance act as you said via Message not understood as a reference to MyModuleMyInstance . A unary message returning a reference to an instance or class or other object. of course you will have a class like ModuleGenerator to handle the technical details for you Version control , dependencies and other technicallities would be handled normally as usually by Metacello with MyModule pointing also to the correct configuration , baseline, whatever. At least thats my general idea of it. On Fri, Oct 13, 2017 at 2:16 PM Thierry Goubier <thierry.goubier(a)gmail.com> wrote: > Hi Kilon, > > then the discussion is a bit different.

Re: [Pharo-users] Namespaces (was Re: Behold Pharo: The Modern Smalltalk)

by Thierry Goubier

Hi Kilon, then the discussion is a bit different. As your example points out, the syntax is already there, but the notion of a module is still open and ties into the package management. I've played a bit with Metacello to have a working "project" concept synchronized with Metacello, and I could imagine providing module like objects (the baseline itself?) giving access to more generic names instead of the internal, prefixed ones. One suggestion maybe: what about trying it for yourself with one of your projects? With a kind of overall class which has the name of the module, and automatically adding methods to it (or a #doesNotUnderstand: that handles those) for all the classes in the module, removing from the class name the prefix? It would allow an experiment, to see how the code looks like and if it is understandable, or if a special syntax is necessary.

Re: [Pharo-users] "Building-With versus Building-on"

VA (VisualAge) for C++ and for Java were two IBM products, the latter being the predecessor to Eclipse.Â Â They were both available on OS/2 and Windows NT variants (2000 mainly), and the C++ version on AIX.Â Â Whichever platform the C++ version was run on, you could target any supported runtime platform.Â Â They were all (along with VisualAge Smalltalk, now maintained and sold by Instantiations and currently at version 9.0, and VisualAge Generator - a Cobol version) written in IBM Smalltalk. I still use VA C++, Java, and occasionally VA Smalltalk, albeit the latter at v. 6.02, in a VM running OS/2 (well, Ecomstation, but it's the same as OS/2 4.5, just updated for more recent hardware - interestingly Arca Noae released a version 5.0, the first official (i.e. called OS/2 version since 2004, in June of this year). Â I use them for prototyping and quickly creating cross-VM client/server apps that allow me to generate virtual network traffic without using tons of memory for each VM (much of what I do involves monitoring network protocols such as BGP, and without traffic to exercise the virtualized aggregated service routers, I can't demonstrate the code without carrying 6 75lb servers on my back). Â I can run Lotus Domino plus 10-12 server apps written in VA C++ in a VM with one or two vCPU's and 256MB RAM.Â Â On the client, I can run a couple dozen Java clients, connecting either to the C++ servers or Domino, in 128MB.Â Â I put a screenshot of the CPP and Java versions below. For Smalltalk code, Pharo is better than VA, certainly better than the 6.02 version, but for C++ or Java, as long as you don't mind prototyping in an old Java version (lacking the syntactic parmesan, mainly), they're still better than anything else. Both incrementally compile/precompile in-memory on save the way ST does, but that's fairly rare in C++.Â Â Both have ways of writing arbitrary test code similar to a playground, which is also rare in either language.

CORBAÂ (Common Object Request Broker Architecture) is a complex way of exchanging objects/data between languages.Â Â I've seen interviewers who are/were developers actually shake if I mention it.Â Â However both the C++ and Java versions handled most of the details without any fuss.Â Â Â All the build/deploy tooling was in the environment. With the app I mentioned, lacking those environments it's maybe not impossible, but likely at least close to 'infinitely improbable' to get the thing built properly, never mind actually change the code and configs.Â Â The junior developer from that project is a friend of mine's little brother, he's still at the company that paid to have it built, and it's now 15 years later, just so it will keep running. Ironically he was fresh out of school at the time and basically worked as a gopher, he didn't write or even debug a line of code.Â Â After we finished the project I taught him how to modify/build it using those tools, and they're still the only thing he can use.Â Â cheersAndrew Â -----Original Message----- Date: Fri, 13 Oct 2017 07:26:13 +0000Subject: Re: [Pharo-users] "Building-With versus Building-on"To: Any question about pharo is welcome <pharo-users(a)lists.pharo.org>Reply-to: Any question about pharo is welcome <pharo-users(a)lists.pharo.org>From: Dimitris Chloupis <kilon. alios(a)gmail.com>What is a VA Java ? and a VA C++ ?Â Call me an idiot or insane but I am in favor of combiding languages, though I only have heard of COBRA never used it.Â I am a lawyer by profession, I know fellow lawyers still using DOS and QBasic databases and yes under windows ...... sadly very common for businesses here.

Pillar (was Re: Behold Pharo: The Modern Smalltalk)

After migrating from Python-powered static-site-generator (to Hugo) and rst markup I was considering to use AsciiDoc(tor) markup for all my content, but, so far, due to using Emacsm settled to use org-mode instead. Haven't tried with slides (yet), but there is Pandoc support for it. Therefore, I'd rather see Pillar support in Pandoc which would buy us even more import/export capabilities for free instead of focusing on single formats like *.odt, *.epub etc. Pillar with 1st class support in Pandoc would, imho, improve status of Pharo itself making it along with Pillar exceelent tool for development as well as for all writing needs - articles, books, documentation, slide-presentations. But it would be nice to make it more transparent where/how can one submit feature request for Pillar? Fogbugs issue trakcer is certainly not the ideal place these days... Sincerely, Gour -- Everyone is forced to act helplessly according to the qualities he has acquired from the modes of material nature; therefore no one can refrain from doing something, not even for a moment.
