Re: [Pharo-users] have a question for morphic Designer in pharo.
by Stephan Eggermont Dec. 28, 2013

Dec. 28, 2013

I was successfull in making Designer start in Pharo 3.0 30659, with some help from Tobias Pape. The following changes were needed (compared to what was needed for Pharo 2.0) - floodfill2:at: is gone from Form. I replaced it with a simple fillColor: That it had gone missing was not clear from issue 11570 - outsetBy: is deprecated and replaced by expandBy: in a lot of places - (some symbol or string or something else, #:) asSymbol is replaced by ... asMutator in a lot of places. - TranslucentColor is replaced by Color TextMorph handleInteraction:forEvent: no longer exists, but gives a different problem in Pharo 2 than in 3 just replacing it by handleInteraction: does not work. That makes a mess of the selection in theUiTextLineMorphs in the object inspector. Stephan

Event handling in TextMorphs
by Stephan Eggermont Dec. 28, 2013

Dec. 28, 2013

handleInteraction:fromEvent: no longer exists in TextMorph in Pharo 3.0. Just replacing it by handleInteraction: doesn't do the right thing. What should I be doing instead?

There is likely to be a different one for designer itself. >2. email to Marcel Taeumel already. but not receive return mail. mabe into spam? Possible, but unlikely. The last days were the worst time of the year to reach someone in Germany. The weeks around christmas (24-26 december) and newyear are family holidays, so it's likely that he doesn't read his mail. He reacted to your stackoverflow post though. >3. latest squeak is cannot use too. squeak 4.1 image(in squeak 4.4 all in one vm) >with morphic designer standard version can use. but class not same(squeak version >and pharo version). im little panic. It should work in the latest squeak image. It is not used enough/doesn't have enough test coverage that all mistakes are immediately noticed, but Marcel fixes bugs that are found. With the quality of issue report you provide the major problem should be his availability/priorities. The next week he's likely to have holidays. >4. im look already. pharo canvas class not same squeak canvas class. >this problem not easy. i try more now. but im newbie user. maybe so hard work. They started as the same, but Pharo has made more radical and drastic clean-ups. Pharo will break existing applications in order to improve things. The advantage is that innovation can be much faster in Pharo, a disadvantage is that applications need to co-evolve. The support for co-evolving is gradually improving, the continuous integration server provided for Pharo contributions gives fast feedback on consequences of changes. Squeak tries to keep compatible with older applications while gradually making everything unloadable. That is a much slower and more difficult approach. Quite a lot of code that was not used was removed. Once in a while we find out that a project uses that code and needs to be reintroduced. Or should be in a separate extension package, or be moved into the using project. The issue you are now running into seems to be the cleaning up of event handling that has taken place in Pharo and not yet or not in the same way in Squeak. A lot of the code deep in the system was very difficult to understand, so yes, this can be difficult work. >5. im look already another UI project(http://uipainter-gsoc.over-blog.com/). >but not handsome(little joke). maybe can then i want use this project. now im trace >another way(for UiItemViewport class. but mouse event is not same to squeak env). Yes, this years GSoC project did not get as far as Marcel's one. And the event handling has changed since Marcel wrote the Designer. Signals was pretty intrusive. UITreeViewPort doesn't seem to correctly set the source of its dragSpec. I tried to change dragDropSpec in UiItemViewPort to dragDropSpec ^ dragDropSpec source: self; yourself That allowed the drag-and-dropping of a lot of the widgets, but created errors where the dragDropSpec was set to nil (Tree widget). Then I looked at where UiItemViewDragDropSpec was used, and found out that the source was not set in UIDesigner initialize. I can do drag and drop of all widgets with self ui widgetList selectionMode: UiViewSingleSelection; dragDropSpec: (UiItemViewDragDropSpec new source: (self ui widgetList); dropEnabled: false; dragTransferType: #widgetClass). So, in all I needed to make the following changes to make the designer work in 20628 after loading development of ConfigurationOfDesigner-mt.24.mcz: UIDesigner>gridForm | form canvas | form := Form extent: 20@20 depth: 32. form floodFill2: (Color gray: 0.98) at: 0@0. canvas := FormCanvas on: form. form pixelValueAt: 0@0 put: (form pixelValueFor: (Color gray: 0.2)). ^ form UIDesigner>initialize super initialize. self ui setupUi: self. self ui prop addPaneSplitters. self selectDefaultModel. self ui centralScroller borderWidth: 0; fillStyle: (BitmapFillStyle fromForm: self gridForm).

Re: [Pharo-users] have a question for morphic Designer in pharo.
by Stephan Eggermont Dec. 27, 2013

Dec. 27, 2013

Thank you for the excellent problem description. Even though I don't know any Korean, the case was easy to follow. You came already quite far in making the designer work in Pharo. I tried reproducing it, but got stuck pretty fast. In a Pharo 2.0 20628 image on a mac, I opened monticello and added the repository MCHttpRepository location: 'http://www.hpi.uni-potsdam.de/hirschfeld/squeaksource/MetacelloRepository' user: '' password: '' In your description, you show that it contains a version 30. The latest version I see is 24. Is there anything you wrote in Korean that I missed to do? The Morphic Designer is maintained by Marcel Taeumel (@ hpi.uni-potsdam.de) in Squeak, and though it is no longer the focus of his research, he makes sure it runs in the latest versions of squeak. I don't think he regularly follows the pharo mailing lists. I think Marcel earlier programmed in Qt, and wanted an event mechanism as similar as possible to that used there. I already told him once that uptake might be better for an announcements based designer. It has a configuration, and the changes you have had to make should not be very difficult to put in a pharo-specific package. positionInWorld is implemented in Morph>positionInWorld ^ self pointInWorld: self position in both Pharo and Squeak. A difference is in the implementation of TransferMorph, where squeak has withPassenger:from: and pharo uses withPassenger:from:hand: Stephan

Is there any fundamental technical barrier to compiling to JVM byte codes?
by Andy Burnett Dec. 25, 2013

Dec. 25, 2013

I am sure it would be a huge amount of work, and may not be a good idea at all. However, given the number of dynamic languages that now compile to JVM byte codes, I am curious whether there is anything about Pharo that would make this impossible? Cheers Andy

Hi, I have loaded WebClient from ConfigurationTool on Pharo 2.0. It seems something changed at system so I had some issues while loading the package and fixed it. I would make my fixes public for community. How do it? Does exist any guide?

Writing an IRC bot
by Sergi Reyner Dec. 19, 2013

Dec. 19, 2013

IÂ´ve been writing a bot for a while now, with the purpose of learning proper Smalltalk and OOP idioms/techniques (IÂ´ve been using C-ish languages for a long time now, and IÂ´m trying to cure myself :D). I must say that the process has been quite enlightening so far, I never really understood OOP until now. So far I have a bot that works fine for my needs, but IÂ´d like to contribute back, so IÂ´ll just list some thoughts and you can comment on them. All constructive criticism and pointers on how to do them are welcome! IÂ´m writing in on Pharo 3. I want to split the code I currently have in 3 parts: - part 1: a couple of classes IRCClient/ZdcSecureIRCClient mirroring POP3Client/ZdcSecurePOP3Client, with the intention of contributing them back to Pharo - part 2: an IRCBot framework, which IÂ´ll likely name 'Chromia', to be released under MIT license too - part 3: my own bot using that framework, which would add all the extras like games Does that sound reasonable? At this point my code is quite messy, so IÂ´m deciding whether to put it on SThub or not yet. IÂ´m depending on http://smalltalkhub.com/#!/~PharoExtras/JSON for reading some JSON file from a website. Though itÂ´s not high on my priority list, I wouldnÂ´t mind making it as portable to other dialects as possible, too. Cheers, Sergi

gtinspector deconstructed

Hi, I took a bit of time to describe how the GTInspector works, what makes it different, and to provide hints for several usage scenarios. http://www.humane-assessment.com/blog/the-moldable-gtinspector-deconstructed It's a long post, I know :), but please take a look. As you might know, this is the default inspector in the Moose image, but it can also be loaded in a fresh Pharo image. I am particularly interested in the following: - if you never used it, and tried it now, what don't you like? - if you used it, was there anything that you did not know? - and of course, what do you like about it?

[ANN] Phratch 1.0beta
by jannik.laval Dec. 18, 2013

Dec. 18, 2013

Hi, I continue to develop Phratch, the port of Scratch in Pharo. Phratch is a visual programming language on top of Pharo. There are lots of new features: - Settings - FileSystems - Metacello - integration of BYOB (allows to build your own blocks) - integration of Color and Files - a lot of new useful blocks - projects saved with Fuel - possibility to implement new features without modifying the core of the system - possibility to customize the environment: add new categories, add new kinds of Sprite, add new blocks. Phratch is available for Pharo2.0 with the following configuration: â Gofer it url: 'http://smalltalkhub.com/mc/JLaval/Phratch/main' username: '' password: ''; package: 'ConfigurationOfPhratch'; load. ((Smalltalk at: #ConfigurationOfPhratch) project version: '1.0') load. (Smalltalk at: #PhratchFrameMorph) open perform: #saveImageForEndUserSilently. â I hope to write documentations about all of the new features asap. You can follow Phratch here: http://car.mines-douai.fr/category/phratch/ and here : https://code.google.com/p/phratch/ Cheers, Jannik

[ANN] JetStorm

Hi all, Another announcement for Christmas. Do you know Lego MindStorms ? The last one is the Ev3 serie (http://www.lego.com/fr-fr/mindstorms/) One particularity of this version compared to the previous ones is the possibility to plug a Wifi key and connect via TCP. So, if you have this material (one Mindstorms Ev3, one compatible Wifi key), a wireshark to obtain the TCP port to connect to Ev3 (See the process here, only to understand why we need a wireshark to know the port: http://www.monobrick.dk/guides/how-to-establish-a-wifi-connection-with-the-…) Now, you can control your robot with Pharo ! Just load these lines: â Gofer it url: 'http://smalltalkhub.com/mc/JLaval/JetStorm/main' username: '' password: ''; package: 'ConfigurationOfJetStorm'; load. (Smalltalk at: #ConfigurationOfJetStorm) loadBleedingEdge. â I know also that for Christmas, it is not possible to learn a new API, we all have a lot of other things to do ! So, you can play with it into Phratch. For that, just load Phratch and the package EV3Phratch as following. â Gofer it url: 'http://smalltalkhub.com/mc/JLaval/Phratch/main' username: '' password: ''; package: 'ConfigurationOfPhratch'; load. (Smalltalk at: #ConfigurationOfPhratch) loadBleedingEdge. Gofer it url: 'http://smalltalkhub.com/mc/JLaval/JetStorm/main' username: '' password: ''; package: 'EV3Phratch'; load. â Have fun ! Jannik PS: for now, this package in prototype, it can change a lot and can have bugs. Do not hesitate to give feedbacks. PS2: I hope to write a doc for it !

About Unix time, TimeStamp, ZTimestamp, and GLORP
by Esteban A. Maringolo Dec. 17, 2013

Dec. 17, 2013

I'm getting the following this Unix time from a REST API: Unix Time: 1387243991 Which is the following GMT: Tue, 17 Dec 2013 01:33:11 GMT And localized: 12/16/2013 22:33:11 GMT-3 So far, so good. If I parse it with ZTimestamp it parses properly (kudos svc): (ZTimestamp fromUnixTime: 1387243991) "prints ->" 2013-12-17T01:33:11Z. But if I parse it with TimeStamp it gives me totally weird output: (TimeStamp fromUnixTime: 1387243991) "prints ->" 16 December 2013 12:0-26:0-49 am Until here it seems to be a matter of printing, the underlying seconds remain untouched. But then when mapped to a timestamp column without timezone with GLORP (PostgreSQL) I'm getting this stored in the database: '2013-12-16 17:33:11' Which once read again by GLORP get's converted to: 16 December 2013 12:0-26:0-49 am (Which asZTimestamp is '2013-12-16T09:33:11Z'). Any help here? If it was my choice, I would only use ZTimestamp, and display localized every time I need. But I don't know if there is a way to map a ZTimestamp to a TZ column in GLORP. Anybody did the "converter" already? Regards, Esteban A. Maringolo

News entries wanted for Pharo website
by Marcus Denker Dec. 15, 2013

Dec. 15, 2013

Hi, We are posting news entries on Pharo.org (and twitter + google plus)â¦ often it is easy to transform an email announcement into a news entry, but sometimes it takes quite an effort. So if you want your news to be published, please send a short text + a picture or link to youtube for the pharo news feed. Itâs much easier to post something that needs no brain power than something where one needs to think how to announce it so it makes senseâ¦ So -> if you announce something via mail, send me (or to the list, or add an issue tacker entry)( a version to be put on pharo.org -> if you have something where you wonder why this was never put there, do the same ;-) Marcus

I'm having issues with a connection coming from an Android app connecting both trough an nginx proxy, but also using some REST testing tools: nginx error log: 2013/12/12 23:23:17 [error] 701#0: *49 upstream prematurely closed connection while reading response header from upstream, client: XX.XX.XX.XX, server: app01.mydomain.com, request: "POST /app-api/v1/auth/login HTTP/1.1", upstream: "http://127.0.0.1:8080/app-api/v1/auth/login", host: "app01.mydomain.com:80" (END) ZnZincSeasideAdapter log: 2013-12-12 23:23:17 897330 D Executing request/response loop 2013-12-12 23:23:17 897330 I Read a ZnRequest(POST /app-api/v1/auth/login) 2013-12-12 23:23:17 897330 T POST /app-api/v1/auth/login 200 114B 42ms 2013-12-12 23:23:17 897330 D ConnectionClosed: Cannot write data while writing response 2013-12-12 23:23:17 897330 D Closing stream I'm using Basic HTTP Auth in each request. But what's weird is that with curl it works perfectly fine. Again, I think this is not strictly Zinc related, but it doesn't work connecting directly to the Zinc server either: 2013-12-13 00:17:02 939035 D Executing request/response loop 2013-12-13 00:17:02 939035 I Read a ZnRequest(POST /app-api/v1/auth/login) 2013-12-13 00:17:02 939035 T POST /app-api/v1/auth/login 200 114B 12ms 2013-12-13 00:17:02 939035 D ConnectionClosed: Cannot write data while writing response 2013-12-13 00:17:02 939035 D Closing stream I don't know if this has to do with the wireless provider doing some proxying behind the wall (which they do), but given the fact that if I try using some REST testing tools from my computer and they also fail, I think it has to do with something else. At nginx I'm forwarding the Authorization header to the Zinc Server: proxy_set_header Authorization $http_authorization; proxy_pass_header Authorization; Is there a way I can log the complete request headers at the Zinc side, and if possible also at nginx?

I am not sure running a 32-bit Pharo VM inside it will be easy, but maybe it is. Can't Pharo run on 64bit host OSes if you install ia32-libs? The VM will sill be 32 bits, with its known limitations. But the idea of setting up the environment locally and then deploying the same environment to a production server sounds really interesting. "Containerization is the new virtualization" they say.
