Re: [Pharo-users] Intermediate-Level Tutorials for Pharo

by tbrunz

Recently, I came up with one such project that might work here, and I spent some time prototyping it. The project is to create an application in Pharo that can solve the "Zebra Puzzle". What's the Zebra Puzzle? It's an example of a "constraint satisfaction problem", which are also known as "logic puzzles". This particular puzzle was published inÂ Life International MagazineÂ in 1962 and consists of a set of constraints for allocating a set of values (properties) of attributes in a mutually-exclusive way: 1. There are five houses. 2. The Englishman lives in the red house. 3. The Spaniard owns the dog. 4. Coffee is drunk in the green house. 5. The Ukrainian drinks tea. 6. The green house is immediately to the right of the ivory house. 7. The Old Gold smoker owns snails. 8. Kools are smoked in the yellow house. 9. Milk is drunk in the middle house. 10. The Norwegian lives in the first house. 11. The man who smokes Chesterfields lives in the house next to the man with the fox. 12. Kools are smoked in the house next to the house where the horse is kept. 13. The Lucky Strike smoker drinks orange juice. 14. The Japanese smokes Parliaments. 15. The Norwegian lives next to the blue house. Now, who drinks the water? Who owns the zebra? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Intermediate-Level Tutorials for Pharo

by tbrunz

tl;dr: I have some ideas about more advanced Pharo tutorials, and I have an example that I would like to have reviewed/critiqued before I develop it any further. I've been thinking lately that it would be nice to expand the number of Pharo tutorials we have available. But rather than (or along with) creating more "beginner" level tutorials, I'd like to see some good "intermediate" level Pharo tutorials. I think that programmers who already know the Pharo syntax and messaging semantics could benefit from more advanced tutorials that demonstrate how to develop "real world" Pharo code for "real world" processing needs. What I'm talking about is something that assumes you know the language, the basics of the IDE (but not necessarily how to leverage its capabilities to aid development), and the basics of the foundation classes (but not its details). I'd like a tutorial for intermediate Pharo programmers who want to become experts with Pharo. Something that can show you how to apply the tools of the IDE and the features of the language and base classes to create solutions that solve complex problems. What does the community think of this idea? -Ted -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] UFFI asynchronous callbacks

by tesonep＠gmail.com

Hello, for executing it you will need the headless VM. If you are using Pharo Launcher you can change the VM for that image in the configuration combo box (The click on "Edit Configurations..."). If you are using the zero-conf you can use "wget -O - get.pharo.org/64/vmHeadlessLatest90 | bash" Cheers, Pablo On Sat, Jul 25, 2020 at 10:17 AM ASAM <vmax28575(a)gmail.com> wrote: > > Hi Pablo, > today I have a little bit of time to try out the "threaded FFI". > But immediately with the load I get the following error message > "PrimitiveFailed: primitive #primitiveInitializeQueueWith: in > TFCallbackQueue failed". > > see pic: <http://forum.world.st/file/t372350/ThreadedFFI.png> > > When I load it again it looks good.

no code is needed as I mentioned ... .... But immediately with the load Metacello new baseline: 'ThreadedFFI'; repository: 'github://pharo-project/threadedFFI-Plugin'; onConflictUseLoaded; load. To rule out possible errors, I tested with a fresh Pharo8 64bit image, of course. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Could you provide the actual code you are running?

Re: [Pharo-users] UFFI asynchronous callbacks

by ASAM

Hi Pablo, today I have a little bit of time to try out the "threaded FFI". But immediately with the load I get the following error message "PrimitiveFailed: primitive #primitiveInitializeQueueWith: in TFCallbackQueue failed". see pic: <http://forum.world.st/file/t372350/ThreadedFFI.png> When I load it again it looks good. But then I get the error message with every Pharo start. To rule out possible errors, I tested with a fresh Pharo8 64bit image, of course. Could you tell me what i'm doing wrong?

by Ben Coman

Searching the table of contents of Pharo By Example I see "Using streams for file access" that would be a good place to start, and then browse other the methods of the classes used there, and also the "senders" of any of those that look interesting. cheers -ben On Sat, 25 Jul 2020 at 15:04, shawon58 <shawonhoque58(a)gmail.com> wrote: > > Hello > i am new in GUI in pharo .

How to get text field value and send to bat file

by shawon58

Hello i am new in GUI in pharo . I am following Spec2 form where i can able to make form that send value and show in result tab. But my concern is i want to send the text field value to a Bat file which will execute a C++ file. So i want to use LibC system: 'a.bat textfieldinput' like this but how to do i dont know. If anyone have idea pleas share with me. In the screenshot u can see that i can send a number that shows in result tab. But now i want to send same number when i press submit than it will send to LibC system: 'a.bat textfieldinput' means in bat it will receive the number from the form.
