Hi Sergio, the standard way to build UIs in Pharo is by using Spec. There is a video of me presenting it at the Pharo Days 2015 that gives you a first overview https://www.youtube.com/watch?v=OL23s9ZUIR0&feature=youtu.be&list=PL4actYd6… There is also written documentation that is being updated now, so not really ready yet. One option is a paper of ours which is a bit out of date but still useful: https://hal.inria.fr/hal-00759030/document HTH, -- Does this mail seem too brief? Sorry for that, I donât mean to be rude!

yes, but i kind of want to avoid the web.. i just want something that works natively without the headaches of browser incompatibility.

I am using Seaside and the UI is web based. Even if Pharo runs locally. Maybe Bloc and a VM running on ARM/Android will change this but as most users are using mobile devices, well, that's the best I can target for now.

GUI Applications

by sergio ruiz

It would seem to me that in order for an ecosystem to really take hold on the part of the users, itâs really important that itâs efficient and easy to create a GUI based application. Can anyone comment on the current state of libraries for creating and distributing GUI applications?

How much abuse can Teapot take?

by sergio ruiz

I am currently planning a mobile (iOS) app that will rely on a REST server for handling offline tasks (sending emails, processing reports, etc). I would LOVE to use Pharo/Teapot for this, but I want to make sure that this configuration would be up to the task. I canât really guess how much traffic it will be getting, so i supposed the question i am asking is: is there a number of requests per second limit that this configuration can handle?

Fwd: Possible Problem in Spawning Warning Messages

by Joseph Kulisics

---------- Forwarded message ---------- From: Joseph Kulisics <kulisics.joseph(a)gmail.com> Date: Mon, Jun 6, 2016 at 6:48 PM Subject: Fwd: Possible Problem in Spawning Warning Messages To: pharo-users(a)lists.pharo.org I have additional information on the #general slack channel on June 3. In short, the problem appears to be that the test runner keeps executing instructions after the initial error and opens a window for each subsequent error, which could be a lot of windows if the error is in the middle of a parse. Here are the screen shots and interaction demonstrating the phenomenon. The screen shots corresponding to the discussion are 2, 3, and 4 at the end of the e-mail. Joseph Kulisics [9:53 PM] Star this message @emaringolo: Actually, now that I look at it, it looks like the program kept executing after the first error. Is that possible? Esteban Maringolo [9:54 PM] Star this message Unless you're forking processes it shouldn't [9:54] Star this message Zinc HTTP client runs on the thread you execute it, so it won't fork anything. Joseph Kulisics [9:55 PM] Star this message I'm not forking anything, but let me show you the windows: Joseph Kulisics [9:55 PM] Star this file uploaded an image: PharoScreenshot.2.png Add Comment Joseph Kulisics [9:56 PM] Star this message This is the code that was executing. The window is the middle one in the stack. dionisiydk [9:56 PM] Star this message It could happen if error is signaled inside announcement processing Joseph Kulisics [9:56 PM] Star this message The first line produces the `ZnHttpUnsuccessful` error Joseph Kulisics [9:57 PM] Star this file uploaded an image: PharoScreenshot.3.png Add Comment Joseph Kulisics [9:57 PM] Star this message The error is what opens the bottom window. [9:58] Star this message The code in the middle window resumes and produces an error at the second line, which raises the middle window, which is pictured first Esteban Maringolo [9:58 PM] Star this message Nothing looks "strange" there Joseph Kulisics [9:58 PM] Star this message Finally, the top window is spawned by the last line of code, which attempts to read a result key from a dictionary parsed from JSON Esteban Maringolo [9:58 PM] Star this message other than the dashes in the method comment Joseph Kulisics [9:59 PM] Star this file uploaded an image: PharoScreenshot.4.png Add Comment Joseph Kulisics [9:59 PM] Star this message So the single test appears to have raised all three of these windows by continuing to run after the first error [10:00] Star this message I couldn't really inspect the stack of windows on the JSON parsing errors because it was just too deep ---------- Forwarded message ---------- From: Joseph Kulisics <kulisics.joseph(a)gmail.com> Date: Fri, Jun 3, 2016 at 9:38 PM Subject: Possible Problem in Spawning Warning Messages To: pharo-users(a)lists.pharo.org I post my question/report to the Slack pharo #general channel, and someone advised me to e-mail the list. I've attached the referenced screenshots. âHere is the interaction: Joseph Kulisics [9:10 PM] Hi. I started using Pharo 5 about a week ago, and I've noticed some peculiar behavior with debugging. When I get an error in a message send, the system now seems to open a warning window for every message in the stack, which can amount to hundreds of messages. In Pharo 4, only one warning opened. In addition, when I select a warning message, I get the debugger with no stack; the stack no longer seems to be aggregated and available to the debugger instance. Is there a system setting that controls the behavior? I looked around---I tried turning off the Glamorous tools---but nothing seemed to have any effect. The behavior is very difficult to work with. Is there an way to use the interface to at least close all of the warning windows when an error occurs? Thanks. Esteban Maringolo [9:12 PM] @offray: Yeap, and I'd also like something like jOOQ for Pharo, it could be done using Glorp internals Offray Vladimir Luna CÃ¡rdenas [9:13 PM] @emaringolo: what is jOOQ ? [9:14] this: https://en.wikipedia.org/wiki/Java_Object_Oriented_Querying ? Esteban Maringolo [9:14 PM] Let's continue in #databases Offray Vladimir Luna CÃ¡rdenas [9:14 PM] Ohh ok Esteban Maringolo [9:18 PM] Joseph, it seem like every action in the debugger is triggering a new debugger, is that what you mean? Joseph Kulisics [9:18 PM] I'm not really about the description at that low a level. I have a testing suite, and when I click on the icon next to a single test to run it, a failing test will open warning windows. [9:19] In Pharo 4, I got one warning for the failing message send [9:19] Now I seem to get one for each message in the stack [9:19] If I click on the message in the warning window, a debugger opens Esteban Maringolo [9:19 PM] Are you running the tests using the Test Runner? Joseph Kulisics [9:19 PM] But the debugger only has one message in the top pane [9:20] Both with the test runner and clicking the icon next to the test in a browser [9:20] In the test runner, I I click a test in error, I get a slew of warning windows Joseph Kulisics [9:24 PM] uploaded an image: PharoScreenshot.png Add Comment Joseph Kulisics [9:24 PM] uploaded an image: PharoScreenshot.1.png Add Comment Joseph Kulisics [9:25 PM] The top image shows the stack of windows that opened in response to selecting the test highlighted in the second image [9:25] (I changed a system setting to open a full debugger instead of a warning window in response to an error, but the behavior is identical when warning windows appear first.) [9:26] As I mentioned, the behavior from the TestRunner is the same. The only difference is that the warnings are suppressed until you select a test in error. [9:26] In Pharo 4, I'd have had one window for the error. [9:27] This example isn't too bad---there are only three windows on the stack---but I've had cases where a test triggered a stack of a couple of hundred warning windows dionisiydk [9:27 PM] Could it be that you test fork multiple processes? Joseph Kulisics [9:27 PM] I either have to exit each one, or I have to kill the image [9:28] @dionisiydk: I don't think so. I don't create a new process in the code, but I can't speak for the underlying libraries like Zinc. In any case, as you can see above, the titles of the three windows are different. [9:29] @dionisiydk: In addition, each window in the stack contains exactly one message, but in exploring the data, the messages all appear to deal with the same set of objects used by the tests [9:31] As I mentioned before, I made the switch to Pharo 5 last week. Before last week, the same tests produced a single error message. [9:31] I did reload the underlying libraries as part of moving my software into the new image, so maybe the underlying libraries changed. Esteban Maringolo [9:33 PM] Could you write a mail to the mailing list? `pharo-users(a)lists.pharo.org`

In Pharo https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessf… Of course, given a ByteArray, whose values are all between 0 and 255 by definition, you can convert it to a ByteString. That String is not a correct (Pharo) String anymore, it is like converting a PNG or JPEG to String, you can do it, it is just wrong. When talking to the outside world, be it over a network connection, or via primitive calls, anything but pure ASCII strings need an encoding. This has to be agreed upon by both parties. If the receiving party wants UTF-8 forced into a (kind of) String, that is (still) possible. Your initial solution seems to indicate that this is expected. This (ugly) conversion should be done at an as low level as possible, IMHO. Sven
