I'm interested in building and using a Pharo based GTD system and would like to use OrgMode files as the database so I can still use the OrgMode ecosystem with its how-tos and mobile apps etc. And then gradually transition to Pharo.

[Pharo-users] Re: [ANN] Pharo Launcher 3.0 released!
Renaud, I experienced the same issue. I assumed that I did something wrong so did-not report it. I installed PL 3.0 over the previous version and I think that this this broke the VM somehow. To fix this, I uninstalled Pharo-Launcher, cleaned out everything in %userprofile%AppDataLocalPharoLauncher, reinstalled it, and now it works again.

[Pharo-users] Re: Illegal Leading Byte
Hi Sven, Thanks for the answer. #windows1252 did the trick. Thanks again. Craig We support more than 80 different character encoders. Of course, you should first know what encoder is being used, after that, it is easy to use a different encoder. Consider: '/tmp/foo.txt' asFileReference readStreamEncoded: #utf8 do: [ :in | in upToEnd ]. '/tmp/foo.txt' asFileReference readStreamEncoded: #windows1252 do: [ :in | in upToEnd ]. '/tmp/foo.txt' asFileReference readStreamEncoded: #latin1 do: [ :in | in upToEnd ]. ZnCharacterEncoder knownEncodingIdentifiers. #windows1252 asZnCharacterEncoder. If you could post a small example of your file, I could try to help. It will probably be #windows1252 or #latin1. HTH, Sven
[Pharo-users] Illegal Leading Byte
Hi Guys, I'm reading a text file which is supposed to be ASCII encoded. This file contains a list of filepaths and was created by a Python program. Well, it turns-out that file names on Windows can contain illegal UTF-8 characters. This causes ZnUTF8Encoder to signal 'Illegal leading byte for utf-8 encoding' and crash the program. I would like to handle this situation more elegantly, is there a more appropriate code-page to use for the Windows filesystem? Craig
[Pharo-users] Private Methods
Hi All, Just a newb off-the-wall question. Is there any good reason why we can't create a true private method in a Pharo class by putting that method inside an instance or class variable as a lambda (block). This would reduce one of my biggest bugbears with Pharo, namely the pollution of the global namespace with every single message name in the entire system. Craig

I think it's just the classic value proposition of having a runtime environment in which further development and debugging can occur.

Ah, I recently condensed the changes file of the Squeak version, so the first download is much faster. I also think the Pharo 6 image I was using is much larger than the Squeak one, for some reason.

You should be able to use the normal meta key for your host platform, it's a bug in the supporting page code in .../js/squeakjs/squeak.js if not. We can handle command key events ourselves and then call .preventDefault() on them, to keep the web browser from chiming in.

That's just the speed of Morphic. The VM is set up to display the spinner whenever anything takes more than a certain amount of time (one alternative is to just turn it off :). While Morphic in SqueakJS has gotten a lot faster since the first release, just because JavaScript engines have gotten faster, I was still motivated to explore alternatives. That's why I experimented with animated HTML wireframes, morphic.js from Snap, and using a separate HMTL5 canvas for each morph. All three of these approaches are much faster than traditional Morphic. However, the traditional Morphic UI has the appeal that it's pixel-portable between the Web and native apps. thanks again, -C -- Craig Latta Black Page Digital Amsterdam :: San Francisco cr...@blackpagedigital.com +31 6 2757 7177 (SMS ok) + 1 415 287 3547 (no SMS)

I'm using Caffeine in production with Squeak; there are a few bugs to deal with in Pharo. Would you like to work together on it? A minimal system is a few hundred kilobytes, depending on the application. The VR app I'm doing now is fairly large and loads in 10 seconds. A small app should take about two seconds.

I wrote: > I wasn't aware that one can livecode JS objects with PharoJS, only > that PharoJS generates JS source which eventually runs in a browser. > Can you give an example? Well, I evaluated the PharoJS playground expressions, and browsed around the proxy support in the index.js that gets installed in a web browser. I could inject the PjLoadForTest class into the web browser and invoke its JS functions via Smalltalk messages from Pharo. I could send #at:put: to the exposed "window" proxy of the web browser (as long as the arguments were JS literals or proxies), and I could also inspect the "document" proxy, but I got an exception when I tried to invoke document.getElementWithId (via "bridge evalBlock: [document getElementById: 'someID']"). Are arbitrary JS messages supposed to work? There isn't much exception handling support beyond relaying JS error messages. (I guess one way to go would be to use the Chrome Debugging Protocol.) I didn't see how to refer to Smalltalk objects from JS (only JS objects from Smalltalk), so it seems the only Smalltalk blocks one can use as JS callback functions are those which only use objects and functions in JS-land. This might be okay for smoke-testing PharoJS apps, but I think the kind of interactive DOM object sketching I mentioned before would be uncomfortable. -C -- Craig Latta Black Page Digital Amsterdam :: San Francisco cr...@blackpagedigital.com +31 6 2757 7177 (SMS ok) + 1 415 287 3547 (no SMS)

Re: [Pharo-users] Accessors vs instance variables
Hi, This is a bugbear for me. On 2015/09/30 09:35 PM, Lyn Headley wrote: Hello, As I understand it, in Smalltalk, the instance variables of a class C are "protected" - able to be referenced by methods of C or its subclasses, but not by other objects. This is a useful feature as it clearly points out which pieces of data are not available to other objects, and thereby simplifies code. However, I am often unsure of whether to use this feature or not, as it conflicts in my mind with the practice of using accessor methods. I like accessor methods because they make it easy to change behavior later -- If I have a dozen calls to an accessor method, then I only need to change it in one place. If these were instance variable references, I would have to do more work. The disadvantage of accessor methods is that they obscure the protected status of data -- it becomes unclear how protected an instance variable is meant to be. (Accessors also make it harder for me to find users of the data when browsing, when there are senders from totally unrelated classes, although I suspect I have just not figured out how to browse scoped in the right way for this). It occurs to me that a tool could be (easily?) developed that would solve this problem. It would take existing variable references and turn them into calls to accessor methods. That way, I could have protection when I want it, and easy ability to change code as well. Does something like this exist, or is it feasible to build? How do others think about this issue? -Lyn I'm old-school OO and don't like accessor methods at all. They break encapsulation, they cloud the object interface, and most importantly they allow bugs to be introduced by undocumented modification of the object's internal state. Nobody has shown me a good reason for their existence and I never use them except where I'm forced to use them in Spec and Glorp. Craig PS: I'm forced to use them in C# as well (my day job). Because in C# it's only way to promote a local variable to a property which is required by most frameworks.

One thing these directories have in common is that they are empty, so as a test I copied a small text file into ‘My Music’, but this made no difference.

Re: [Pharo-users] Alt-tab between windows
2015-05-19 11:41 GMT-03:00 Avdi Grimm : It took thousands of programmers decades of work in many different languages to create this variety. I'd hate to see the smaller Pharo community pour tons of effort into re-inventing these solutions. Which is why I'm suggesting that it may be more helpful to re-frame the problem. General purpose window management is a problem that has been solved many times over. Do you really want to do it yet again? I suspect that with some careful examination of Pharo coding workflows, you could find a way to obviate the need for zillions of windows, and solve a simpler problem instead. Some ramblings: 1. I quite like the way the alt-browser allows you to navigate through your code by clicking on methods and classes in a tree to see the code in the right-hand pane. Take that one step further by having the browser open a tab for each method that you click on, or switch to the tab - if there is one open already, and you will have taken a giant step towards most modern IDEs[1]. 2. One way to solve the alt-tab issue is to use the OS 's window manager, instead of managing the windows in the image. This also has the added benefit of incorporating the OS window manager's features and look and feel into Pharo for free. The ability to drag a tab out of the image window onto it's own display in a multi-headed setup would be very welcome to me. Craig 1. My reference points here are M/S Visual Studio which I use daily and Netbeans which I use for mobile(Andriod) work.

Hi Sven, I count myself as a beginner with Pharo, although I've been dabbling with Pharo UI choices for a few months now. Like Sebastian, I wrote Spec off as too immature for prime-time, but I too come from the commercial world, so maybe my expectations were unrealistic. So I took the time to learn Spec. My very first requirement is to display some data in a grid or table like manner, so I took a look at the TreeModel, and tried to adapt one of the examples to fit. However, whenever I try to add a third column to the model, I get a "Subscript Out of Bounds". I also tried to change the oddRowColor, but it had no effect. I hope that is specific enough for you.

[Pharo-users] GUI Frameworks Choice
Hi All, I'm new to Pharo although not to Smalltalk. I did dabble with Dolphin about 20 years ago, when it was first being developed, and did some quite cool stuff. This time around I chose Pharo because I feel that Dolphin has strayed from the pure OO model that I enjoyed back then. I've chosen a fairly ambitious GUI project as my Pharo primer. The problem is - which GUI framework to use. The GUI that I want to build will be static but complex with a menu, 2 toolbars, 20 odd toolbar buttons, and 3 (dockable?) windows, containing Trees, lists and text editors. Any suggestions on which GUI framework would suit? I thought about using PolyMorph, but I cannot find the examples in my Pharo 3 image. Craig
