About validation
by StÃ©phane Ducasse March 11, 2018

March 11, 2018

Hi I read the chapter on validation of the mentoring course book of andres valloud. http://www.lulu.com/fr/fr/shop/andres-valloud/a-mentoring-course-on-smallta… And I love this extension of SUnit. I loved the idea when I saw it for the first time at Lugano (presentation of Leandro Caniglia). I encourage everybody to read it. Now does anybody implemented in Pharo the SUnit extension? I would like to play with it and eventually write a chapter on it for the next book. The idea is so good. Stef

Re: [Pharo-users] Slot questions
by Paul Davidowitz June 2, 2015

June 2, 2015

To Camillo Bruni: I'm not using any slot image (I only looked over the paper). According to the Pharo book, 'pvt' should be implemented in the mainstream image. To Marcus Denker: There are actually several methods in the image with the 'pvt' prefix. Please update the doc (Pharo book) to remove talking about 'pvt'. It would have saved me a little headache :)

funny idea Symbol vs. Selector
by stephane ducasse May 14, 2015

May 14, 2015

Hi guys I'm thinking aloud... I was wondering if we could not take advantage of a new class: Selector. MethodDict would only contain selectors and not symbols. I remember that I talked about that with hernan. Stef

How do I save contents of Workspace into a collection?
by Frank Church Jan. 31, 2015

Jan. 31, 2015

Hi guys, My images are gathering a number of Workspaces whose contents I don't want to delete. I want to create a collection of Workspace contents along this defintion: Description Date Category Content (the actual text in the Workspace). In the final version I would like to be able to select a workspace and simply click a button or a menu item and get a dialog where I can enter the Description, Category and Date with the Workspace contents automatically captured into a text box. Copying and pasting the contents would be okay to start with. Filing it out would be another aspect later. What kind of array would best suited to the task? There is quite a number of them depicted here: http://www.jmcsweeney.co.uk/computing/m206/collections_intro.php What could be the best way to go about it? For those who are curious I am experimenting with the original ideas of Smalltalk where a computer user would do everything in Smalltalk workspace/desktop. I am intrigued by the possibility and somehow it seems eminently doable. -- Frank Church ======================= http://devblog.brahmancreations.com

if Pharo is key for you

Hi guys if Pharo is key for you then you should ask yourself what you did for Pharo recently. Writing code, writing documentation helping closing bug entries, participating to the association, to the consortium... Pharo is not happening from spontaneous generation. Stef

Slots
by Thomas Worthington May 19, 2014

May 19, 2014

I notice that "Slots" are slated for addition in Pharo 3.0. Is there anywhere I can see which model of "slots" is being suggested? I'm not sure that slots, in the sense of Javascript, are a good idea generally and, in the broader context, I'm very unhappy with the idea of messing with Smalltalk's generally clean syntax by adding new language features. Could the desired effects be achieved by subclassing Behavour or somesuch high-level approach? -- Thomas Worthington

SerialPlugin on MacOS
by Bernat Romagosa Feb. 20, 2014

Feb. 20, 2014

Hi list, Developing a multi-platform application is not so easy when you have to deal with hardware it seems... So I'm having this PrimitiveFailed error on MacOS, using the latest stable VM listed on the pharo-project website on Pharo20: *PrimitiveFailed: primitive #primWritePortByName:from:startingAt:count: in SerialPort failed* The same code works fine both in Gnu/Linux and Win32, so I'm guessing it's a problem with the serial plugin included in this VM. Any ideas? Cheers, Bernat. -- Bernat Romagosa.

Mongo cache vs database objects
by Sabine KnÃ¶fel Dec. 2, 2013

Dec. 2, 2013

Hi Esteban, all, I work with mongo daily an it works fine, I am very happy with it. As you told me, with >>VORepository current reset. I can force re loading all objects from database and resetting the cache completely. This is helpful for development eg. after changing the magritte descriptions. My question: Is there a possibility to make a query and tell voyage that THIS query should be done within the database and NOT within the cached objets? And that all objects and the child objects from this query are loaded freshly from database into the cache. My concrete situation: I want that if the user logs in, his objects are loaded from database and NOT from cache. This means the person, his trips etc. And the question coming along with this: How long does the cache keeps objects/when are they reseted (except the >>VORepository current reset)? If I would never take a new image and never make a reset, would all objects remain in the image (and the database objects wold never be read)? In this case what about the size of the image?

Finalization
by Sean P. DeNigris Nov. 29, 2013

Nov. 29, 2013

I found the following list threads... http://forum.world.st/Finalization-question-td1300962.html mentions #beFinalizable, which doesn't seem to exist. I guess it was just an example, but seems like it should be added, no? In http://forum.world.st/object-finalization-td3771196.html Igor suggested that the key is to do: WeakRegistry default add: obj. This guarantees? that #finalize will be called when the object is garbage collected. I'm asking regarding my recent work wrapping the FMOD sound library with NativeBoost. I'm thinking my NBExternalObjects should release their resources when no longer referenced. I want to say: FmodSound>>#finalize self primReleaseSound: handle. So I've pieced together that I would have to also write: FmodSound>>new instance := super new whatever; beFinalizable; yourself. Object>>#beFinalizable WeakRegistry default add: self. Am I correct that: 1. The above code would cause the resource to be safely released when the sound object was garbage collected? 2. This approach would be a good way to manage these types of resources? Any hints would be appreciated as to the best way to accomplish managing these...

What is "Primitives"?
by Nicolai Hess Nov. 29, 2013

Nov. 29, 2013

Looking at the code for DiskStore>>basicEntryAt: I find this code: "Primitives lookupDirectory: encodedPath filename: encodedBasename)" What is this "Primitives" not a class? I am suprised there is some code that I can not find the source for. Ok, it has something to do with vm primitives, and I know that code like <primitive: 'primitiveDirectoryEntry' module: 'FilePlugin'> is in the vmmaker-package for FilePlugin. BTW it is terrible hard to load vmmaker in a "normal" image. Now I use the generator.image from pharo http://files.pharo.org/vm/src/. But even in this image it is not possible to load the vmmaker tool.

Snap4Arduino pre-alpha release
by Bernat Romagosa Nov. 28, 2013

Nov. 28, 2013

Hi list! I know people don't usually make announcements of this kind here, but I've gotten much help from this list on SerialPlugin and NativeBoost questions, so I wanted to let you know I've managed to release the pre-alpha version of Snap4Arduino. Snap! is a Scratch reimplementation written in Javascript by Jens MÃ¶nig and Brian Harvey, with advanced programming concepts such as first order functions, closures or continuations. As Brian Harvey puts it: *In the glory days of the MIT Logo Lab, we used to say, âLogo is Lisp > disguised as BASIC.â Now, with its first class procedures, lexical scope, > and first class continuations, Snap! is Scheme disguised as Scratch.* Snap4Arduino is a modification of Snap! plus a server written in Pharo that allow you to live-program Arduino boards very easily. http://s4a.cat/snap I've used Zinc as a web and websockets server, and the Arduino package to achieve communication with the board. I've decided to not wait for the MacOS CogVM serial port bugfix because I really wanted to release something before the end of November, but everything else is in place, so once the VM is fixed, it'll be just plug and release! :) Thanks a lot for your help! -- Bernat Romagosa.

NativeBoost Questions while wrapping FMOD
by Sean P. DeNigris Nov. 25, 2013

Nov. 25, 2013

I'm wrapping the FMOD cross-platform audio library. The code is MIT and lives at http://smalltalkhub.com/#!/~SeanDeNigris/FMOD ======== Problem #1: ======== I'm calling into the FMOD library with: primStoreIsPlaying: channelHandle in: isPlayingHandle <primitive: #primitiveNativeCall module: #NativeBoostPlugin> "FMOD_RESULT FMOD_Channel_IsPlaying( FMOD_CHANNEL *channel, bool *isplaying);" ^ self nbCall: #(FMOD_RESULT FMOD_Channel_IsPlaying(NBExternalAddress channel, NBExternalAddress isPlayingHandle)). I call the above with: isPlaying | isPlaying | isPlaying := NBExternalAddress new. self primStoreIsPlaying: channel in: isPlaying. ^ isPlaying value > 0. isPlaying is always 0. The method works directly from C with: int isPlaying = 1; while (isPlaying) { FMOD_Channel_IsPlaying(channel, &isPlaying); } I also tried changing the callout signature to "... bool* isPlayingHandle)" and passing "isPlaying := true." instead of using the NBExternalAddress stuff. I have a few more questions, but this is the most pressing as it's holding up any further development.

PharoLauncher howto (was: SimplePersistence ...)
by Torsten Bergmann Nov. 25, 2013

Nov. 25, 2013

Norbert wrote: >How do you use it? Iâve just downloaded but failed to see how I can work with it. Warning: ======= Note that PharoLauncher is a project still in progress - I think Damien can tell you more about all the nice stuff. I just contributed some code and use it daily now. But lets continue with a short HOWTO (from my personal experience): -------------------------------------------------------------------------------------------------- PharoLauncher HOWTO: ==================== Before ====== I'm typically on Windows - in the past I had several folders with images everywhere on my HD. Sometimes with the VM, sometimes without. Lots of image searching as you can imagine. How I installed it: =================== So I downloaded a VM from http://files.pharo.org/vm/pharo/ and the latest ZIP with image and changes from https://ci.inria.fr/pharo-contribution/job/PharoLauncher/ I also put the source file into the same directory which I copied from the regular Pharo distro. All lives in one directory. I also use Linux boxes, for Ubuntu follow: http://www.pharo-project.org/pharo-download/ubuntu to get the launcher. Note that this currently will install an old image, so you have to load newer packages afterwards in the image or exchange the image. Installation will surely be simplified in the future. How I use it ============ Just launch the Pharo launcher image using the platform specific VM. Usually for "end user experience" the launcher opens in full world mode - so you see no Pharo background/world menu - only the launcher. Initially on a new computer the left side with local images is empty. On the right side are the images that are available on the web. Note that there are refresh buttons at the top of the list. Click "Refresh" in the right list to fetch all available images from the web. Select the image you like and download it. For instance you can download "Pharo3.0" -> "30587" which is the latest image as of today. Note that also the images from contribution CI are available. So you can easily download "Artefact", "Moose", ... images if you like. It will download the image into a specific directory somewhere in your users home directory. Each image gets an own folder. Use the "Show in folder" menu item if you want to open this location (may not yet work on all platforms) After download you can either "Launch" the image from the context menu in the right list. This will open the new image and close the launcher image. So you are ready to start working. What I do typically do is to "Copy" the image BEFORE I do any work and name it differently like "30587-MyStuff". Then I Launch the new copy and work with it, later throw it away or try that loading after commits works within new fresh images, ... Now === My HD is now much cleaner - all images are in a central place and I need only one icon/starter on the desk to open. PharoLauncher is also a very handy tool to download specific image update versions if you want to reproduce or fix Pharo bugs. I also associated one of the unused laptop keys with PharoLauncher - so the world of Smalltalk is just one click away... Things to know: =============== At the bottom there is a button to open a settings browser with specific settings for PharoLauncher. There is an option that enables the IDE again - so you can inspect the code or fix a bug. If it does not launch on your box then set a break in PhLImage>>launch to debug. Also note that it does not fit with the "Save as" image style - since each launcher image has to be in a new directory so far. So either use the "Copy" image, then "Launch" and then only "Save" in the target image or copy the "Saved as" image in a new folder and refresh the Launcher view on the right side. When you develop for it ======================= Either use the latest image from CI and enable the IDE as written before. You can also download the latest also in a Pharo 3.0 image. Just use the ConfigurationOfPharoLauncher from http://smalltalkhub.com/#!/~Pharo/PharoLauncher Then evaluate "PharoLauncher open". Currently it was rewritten using Spec for the UI, also all the actions are rewritten using Command Pattern so you can extend the buttons, menues if you like. Hope this helps a little bit Bye T.

[launcher] templates from fixed URLs
by btc＠openinworld.com Nov. 25, 2013

Nov. 25, 2013

Hi Damien, I like the PhLFixedURLsTemplateGroup you just added to directly reference specific urls like Pharo 3.0 latest. I corrected a problem with Settings. Also I think its useful to be explicit about the ones that refer to 'latest' so I made that change. Could you review these. The next great thing would be to allow users to add their own fixed urls without coding. btw, I was going to follow your example to change PhLTemplateGroupRepository>>refreshLocal to >>refreshFast but it seems the only sender is itself, and also inserted breakpoints do not trigger. Looks like it is surplus to requirements. cheers -ben

Bootstrap for Seaside question
by Torsten Bergmann Nov. 25, 2013

Nov. 25, 2013

>Bootstrap for Seaside is really cool, it allows to quickly build something that looks very polished. Thanks Torsten! You're welcome. In return you should send give a screenshot and short description for the Pharo success story page. The more showcases we have the better it is... Regarding your question: #tbsButton returns a button as the name says. TBSButtonTag is a subclass of WAButtonTag because the offical examples are also using <button> See http://getbootstrap.com/components/#btn-groups But a button should also support #callback: So it is not an anchor by default. Make sure to have a #form: around it and #children is correct. Otherwise callbacks will not work. Note: you can also leave out the whole bootstrap wrapping part and use Bootstrap styles directly, for instance with an anchor: html anchor class: 'btn btn-default'; callback: ... with: [] Haven tested since I have no image at hand - but should work out of the box. One could easily wrap this into a #tbsAnchorButton and "WAAnchorTag subclass: #TBSAnchorButtonTag" supporting the same API. Contribute code + tests if you like. I added you on STHub. Bye T.

[Athens] Finding if a line passes through a specific pixel .
by kilon alios Nov. 25, 2013

Nov. 25, 2013

So here we are with my first challenge. I am making Hyperion, a vector graphics editor using Athens , so far I have a nice line with several segments, I have added nice handlers to allow me to move the points (start and end of each segment) of the line around with the mouse, but now I want each time I click on a segment itself to create a new point.This way I will create more points with the mouse and bring more detail to the shape of the line / path. In order to do that I will have to check that the line passes through a specific pixel. Or to be more correct that the place that mouse has clicked is where my path passes through. How I do that ? Can Athens do that ? Can athens tell me which pixels my path passes through ? At first I thought to return the Athens surface as a Form but the form will give me back the colors of each pixel on a specific place, but that does not guarantee that my line / path passes through those pixels.

Bad UT8 encoding got with a SQLite3 query
by Torsten Bergmann Nov. 25, 2013

Nov. 25, 2013

>I know nothing about the sqlite3 code, but if you canât find unit tests doing non-ascii stuff, and you can't find conversion >code, than the original author(s) probably just didnât implement it. > >I might be wrong, but that would be a shame, since utf-8 encoding/decoding is fully supported in Pharo. Yes it is not implemented. As in any other open source project it is a question of time and contributions. History of SQLite3 package is much much older than Pharo - original implementation was for Squeak (Avi Bryant's SQLite (v.2) wrapper), I then packaged it up as an MCZ so it did not get lost and a repository on SqS was created. Andreas Raab then contributed to it, he was at my knowledge the only one who really used it in own projects. Later after the closing of SqS was announced I moved the code to STHub. As I already mentioned - code is rather old, based on unmaintained FFI and it should better be redone using NativeBoost because I'm sure meanwhile also SQLite library already made some progress.

How to discover which test fails (pharo 2.0)
by Davide Varvello Nov. 25, 2013

Nov. 25, 2013

Hi! I'm on Pharo 2.0. When I run a bunch of tests I usually select a lot of packages from Nautilus and click cmd-t to run them, but unfortunately if one test fails, only a yellow box in the lower left appears and it's time consuming to look for which test fails in which package. I'd love to have the good old dialogs with all the failing tests. Is there a way, in the configuration, to have them back?

Bad UT8 encoding got with a SQLite3 query
by Michel Nov. 24, 2013

Nov. 24, 2013

Hi everyone, I have a sqlite3 data base which is UTF8 encoded. Accessing to it with a ruby script gives me the right encoding for accented vowel, and doing an hexdump of the file too, but I get a strange one with the sqlite3 package in pharo 2.0. For example, for 'Ã©' (UTF8 0xC3A9) I get 0xA6A9, for 'Ã¨' (UTF8 0xC3A8) I get 0xA6AE, for 'Ã ' (UTF8 0xC3A0) I get 0xA686, for 'Ã¹' (UTF8 0xC3B9) I get 0xA69A, ... Looking at the smalltalk code I didn't see any translation and of course if I attempt to use the UTF8TextConverter I get an error. Any idea ? Thanks in advance. Michel.

Bootstrap for Seaside question
by Johan Fabry Nov. 24, 2013

Nov. 24, 2013

Hi all, I'm using Bootstrap for Seaside to make a small web app for managing the hardware resources (Lego Mindstorms! :-) ) of a course I am giving next semester. Bootstrap for Seaside is really cool, it allows to quickly build something that looks very polished. Thanks Torsten! But now I have a question: I am using buttons at some place in the app (to remove a registered inventory), but I cannot get the callback to work, the examples do not show how to do it. The code I have is below: html tbsButton beDanger; callback: [inv inspect]; with: 'Delete!'. How do I make this work? It seems strange to need to to place an anchor in the button for it to work. ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

Deploying a polymorph app - two questions
by kmo Nov. 24, 2013

Nov. 24, 2013

I have written a small Polymorph application in Pharo 2.0. I have some questions about deploying it. My app consists of a single morph. I would like to fill the pharo window with the morph and have the morph resize when the user resizes the pharo window. I'm pretty close to what I want. I have made my morph a subclass of FullscreenMorph and it is filling the window nicely. I just need two things. One - I need to change the pharo window title to the title of my application. I have tried DisplayScreen hostWindowTitle and it seems to have no effect. Two - I need to get rid of the Pharo window status bar - the one at the bottom which shows you the various windows, browsers, and workspaces you have open. Can anyone give me some guidance?

How to combine Pharo Desktop and Seaside?
by Torsten Bergmann Nov. 23, 2013

Nov. 23, 2013

Hi, If you want to write your collection to a static HTML page you can |aCollection| aCollection := #('Smalltalk' 'Object'). FileSystem workingDirectory / 'test.html' writeStreamDo: [:stream | stream nextPutAll: '<html><head></head><body><ol>'. aCollection do: [:each | stream nextPutAll: '<li>'; nextPutAll: each asString ]. stream nextPutAll: '</ol></body><html>']. and then serve it from an external webserver (like Apache or Nginx). But this is static html file generation. I'm sure you want something more dynamic. So you can serve the contents right from the image using one of the Smalltalk webframeworks like Seaside or Aida. Here is a short Seaside HOWTO for this: Prepare an image with Seaside ============================= - download Pharo 2.0 from www.pharo.org - start it, then select "Tools" -> "ConfigurationBrowser" from the world menu to open a list of additional loadable packages - search for "Seaside3" and click on "Install", this will install the seaside web framework into your image - When loading is finished just open a workspace ("Workspace" from world menu) and evaluate ZnZincServerAdaptor startOn: 8080 This will start a local webserver right from your Pharo image on the given port. - check with a web browser (Firefox, Chrome, IE, ...) that Seaside is running by opening http://localhost:8080 There you can browse first Seaside examples. As an alternative to the above steps you can also download a premade Seaside distribution from http://seaside.st Implement your own webapp ========================= - open the Nautlius System browser ("SystemBrowser" from the world menu) - implement an own Seaside component class WAComponent subclass: #MyHome instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'KillerApp-Web-UI' - now register this class for Seaside by evaluating the following expression in a workspace WAAdmin register: MyHome asApplicationAt: 'killerapp' This registers your component as an own custom seaside application under /killerapp. - so if you point your browser now to http://localhost:8080/killerapp you will see an empty page - but it means you application is there but has not yet some content - now implement an instance side method called #renderContentOn: on the MyHome class renderContentOn: html "Render a collection as html list" |coll| coll := #('Seaside' 'is' 'really' 'cool'). html orderedList list: coll. - refresh your browser on http://localhost:8080/killerapp you will now see the contents of the collection How to continue =============== Read books, try to implement something and if in doubt just ask on the mailinglist. There is also a seaside mailinglist http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside Learn about Pharo by getting on of these books: http://pharobyexample.org/ http://rmod.lille.inria.fr/pbe2/ learn about Seaside http://book.seaside.st/book learn about Smalltalk in general with these free books: http://stephane.ducasse.free.fr/FreeBooks.html

Cleaning up Voyage Documentation
by Johan Fabry Nov. 23, 2013

Hi all, I am building a small app that uses Voyage and MongoDB as the database, and so I had many questions regarding how to use it and found the documentation lacking. After conversing with Esteban, I proposed that I improve the 'Pharo for the enterprise' chapter on Voyage, based on his responses to my questions. (See https://ci.inria.fr/pharo-contribution/job/PharoForTheEnterprise/lastSucces… and https://github.com/SquareBracketAssociates/PharoForTheEnterprise-english/tr… for the sources) So a heads-up: I would like to take a 'lock' on that text for some days (to avoid conflicts and the associated unpleasantness), as I go improving and expanding it in the next few days. Also, if you have questions and/or remarks about Voyage and/or the documentation, shoot! I will do my best to address them.

How to combine Pharo Desktop and Seaside?
by Torsten Bergmann Nov. 22, 2013

Nov. 22, 2013

You can initialize your instance variable in an initialize method WAComponent subclass: #PrintHtml instanceVariableNames: 'tasks' classVariableNames: '' poolDictionaries: '' category: 'KillerApp-Web-UI' Then a method to initialize on the instance side PrintHtml>>initialize: initialize "initialize the receiver" super initialize. tasks := #('read' 'before' 'you' 'try') If you send #new to a class this #initialize method is automatically called. If you do not want it use #basicNew. So if you enter PrintHtml new in a workspace and select "Inspect it" to open an inspector on the new object this method gets called and therfore you will see that the instance variable should have the collection as contents. Side note: Do not forget the "super initialize" in this method - otherwise superclass initialization for seaside components is not done. Then use a normal rendering method to display the ivar in the browser renderContentOn: html html orderedList list: tasks If I understand you correctly you want to know how you acces the Seaside generated code for a WAComponent subclass also in a workspace. This is easy: |component| component := PrintHtml new. "your seaside component" WARenderCanvas builder render: [ :html | html render: component ] which should return the generated HTML: '<ol><li>read</li><li>before</li><li>you</li><li>try</li></ol>' now. That is one way. The preferred way for Seasiders is to directly look at the generated HTML code in the webbrowser. Just go to your app: http://localhost:8080/killerapp Down at the bottom you will find the seaside development toolbar (only visible when developing) and then click on "Halo". Now Seaside renders a rectangle around each component and you can click on "Source" to Switch to the source of a component. Also try the other buttons there. For sure you should read one of the introduction stuff on Seaside, I would recommend the online Seaside book: http://book.seaside.st/book Bye T.

Pyret: adding tests directly into classes
by Andy Burnett Nov. 18, 2013

Nov. 18, 2013

I have just come across the Pyret language. It looks interesting, but the part which particularly caught my interest was the way that they had built the unit tests directly into the classes, rather than having separate test classes. I think this is an interesting idea. It seems as though it would be easier to manage writing tests if everything were in one location. And this - might - mean that people were more likely to write tests. Has anyone else looked at this, and have an opinion on whether it would be a good addition to Pharo 4/5/X? Cheers Andy

CogVM arguments in Win32
by Torsten Bergmann Nov. 18, 2013

Nov. 18, 2013

Hi Bernat, >how do I translate this into NB code Either invite Igor (author of NB) for lunch or try this: Its a C-structure, you convert it by wrapping this in a sublcass of "NBExternalStructure". See the examples already in a Pharo 3.0 image. Basically you need: - define a subclass NBExternalStructure subclass: #WinNotifyIconData ... - define the correct fields in a class side #fieldsDesc method according to the native data types used in the structure - call "WinNotifyIconData rebuildFieldAccessors" - setup the types in a shared pool that you can include later: - define the pool: SharedPool subclass: #WinTryIconConstants ... - in a class initialize method you can setup the type initialize NOTIFYICONDATA := #WinNotifyIconData. PNOTIFYICONDATA:= 'NOTIFYICONDATA *'. - by including the pool you can use "NOTIFYICONDATA" or "PNOTIFYICONDATA" in any native boost call. If you are in Pharo 3.0 load "OS-Windows" package from the config browser. Check the subclasses of NBExternalStructure there. I wrapped many other windows structures already so you can get an idea about it. For instance have a look at WinConsoleConstants>>initTypeConstants, there you will find the CONSOLE_CURSOR_INFO, CONSOLE_SCREEN_BUFFER_INFO structs wrapped in WinConsoleCursor, WinConsoleScreenBuffer classes. Compare them with the MSDN struct description. >Could the Windows API be any more convoluted and dev-unfriendly in any >possible sense? This question should go to M$ not Pharo-user ;) Bye T. BTW: I'm not sure "PNOTIFYICONDATA" alone will solve your problem if I remember correctly from my Smalltalk/MT and C/C++ times also playing with tray icons. I guess you need a callback that gets called when the icon is clicked or the tray icon menu is choosen (see uCallbackMessage member in the struct). You also need a handle to an icon - either the icon from the EXEs resource section or by loading one from a bitmap. That means wrapping the icon or bitmap apis too...

We already have ways to "jump to tests" in Nautilus, and we will continue improving that to show them together (for example). But I do not think the tests need to be *in* the class definition to have same level of interoperation. Esteban >>> I agree. The actual architecture doesn't matter. The critical factor is making it as easy as possible to write/navigate tests. I didn't know about the Nautilus features. I shall have to go and experiment. Also, thinking about Doru's point. I wonder if we could write tests/examples in the comments section of code. It might be an interesting addition

Re: [Pharo-users] Pyret: adding tests directly into classes
by Andy Burnett Nov. 17, 2013

Nov. 17, 2013

Doru said: <<< I stumbled across this idea when Markus Gaelli chose it as a PhD topic about ten years ago (man, I'm old). The main idea was not to provide tests, but examples that happened to have assertions. The goal was twofold: (1) provide live documentation with real objects, (2) provide another way of composing tests. The project did not really come to fruition, but I still think this is highly interesting topic. Part of the ideas were later implemented in Phexample (http://www.smalltalkhub.com/#!/~Phexample/Phexample/) and JExample (http://scg.unibe.ch/research/jexample) >>> That's really interesting. I had never heard of Phexample - so many interesting projects, so little time! - I like the approach of building on tests. Do you know if this will work in Pharo 3? Also, I may have misunderstood what Pyret was doing. Perhaps it is more about examples.

In the multi language demo of QCMagritte, a magritte visitor is used that changes all label:, checkboxLabel:, comment: and group: sends in descriptions to automatically use a multilanguagestring. The parameter is used as the key. All unique keys are collected. The default translation is the key. That is used for missing translations. Languages can be added on the fly. The demo has a simple UI to directly add and change translations. The whole translation table can be written to csv, and read back. This is not shown in the video Stephan Verstuurd vanaf mijn iPhone

Finding references to traits

If I come in cold to a system and see some class using trait, and then I want to find all classes that use that trait. I have tried a few ways but failed to work it out.

[Spec] How to adding my scroll bar
by Gisela Decuzzi Nov. 16, 2013

Hello, I have a component that basically contains lot of widgets and I want to add a scroll bar to it. But I didn't find a way to do this. I'm using Pharo 2.0 (I know 3.0 is better but I needed something stable). My spec is a ColumnLayout with lot of rows. Maybe I should use another? Can someone point me where to look at?

NBOpenGL on Pharo 3.0
by Richard Wettel Nov. 15, 2013

Nov. 15, 2013

Hi CodeCity, the project I am working on is based on NBOpenGL. I'd like to start working on it using Pharo 3, but it seems that NBOpenGL does not work yet with Pharo 3.0. I downloaded from jenkins the latest image with Pharo 3 and tried to execute the following code on Windows 7, 64 bits: GLTTRenderingDemo new openInWorld. but I get a 'No suitable implementation found for initializing OpenGL context for your platform'. It seems that NBGLContextDriver does not have a subclass for Windows 64bits. Did I omit something? Cheers Ricky

Arduino package extra files

Hi list, After successfully installing the Arduino package, I noticed this Getting Started text: *After installing the Arduino packages by evaluating...* * * * ConfigurationOfArduino load.* * * *...you'll need a couple extra support files in order to be able to upload programs to your Arduino board. You can download them from here:* * * * http://www.mediafire.com/?1rep41uygl4rpf1* * * *Extract the contents of that file in the same directory where you have your Pharo image.* But the mediafire link is broken. Where can I get the extra support files? Thanks! Bernat. -- Bernat Romagosa.

It really needs a configuration :-) You mean a configuration like the one I attached :) Did you notice the new "Config+" button on the metacello browser - it helps creating new configs. I also added a postload for plugin registration. Feel free to use and put into your STHub repo. I found two bugs in Periscope using Pharo2.0 #20627: 1. When one enters "Obj" to search for object it crashes in the spotlight 2. When one opens tools like the Configuration browser they show up inside of the area of Periscope... If this gets fixed and config gets usable for Pharo 2.0 then do not forget to add the updated config also to "MetaRepoForPharo20" on SS3. This way it will show up in the config browser and can easily be loaded. Thx T.

Looking at the code I notice that it looks for libGL.so under /usr/lib/libGL.so. In modern versions of 64 bits Ubuntu, and Linux Mint which is derived from Ubuntu, libGL.so is not placed under /usr/lib, instead is placed in a driver dependent folder, which is referenced by a config file in /etc/ld.so.conf.d/ . With a mesa driver, the OpenGL library is at /usr/lib/i386-linux-gnu/mesa/libGL.so.1 , so the driver shared object path cannot be hardcoded. The path problem is a know issue, yes.

Who uses poolDictionaries? New class template cleanup

Hi all, I am preparing slides for a course.

Why not add this to Class: Class>>subclass: aSymbol instanceVariableNames: instVarNames classVariableNames: classVarNames category: aSymbol ^self subclass: aSymbol instanceVariableNames: instVarNames classVariableNames: classVarNames poolDictionaries: '' category: aSymbol And have the new class template as follows? Object subclass: #NameOfSubclass instanceVariableNames: '' classVariableNames: '' category: 'Kernel-Classes' It would be a bit cleaner. I know us old timers don't even see the poolDictionaries: line anymore, but I dislike having to explain it to students.
