by Daniel Roe Dec. 23, 2013

Dec. 23, 2013

I am trying to install Pharo on a Win7 64 bit computer and am following the examples given in the manual. I open up a new workspace and type in time now Then choose - print it - from the action menu and I get an error message stating that the receiver of "now" is nil. i realize it's probably something really stupid I'm missing but I need help please.

Roassal3D : MessageNotUnderstood:NBMSAAOffscreenDisplay
by Volkert Barr Dec. 20, 2013

Dec. 20, 2013

Hello, i loaded Roassal3D from the Configuration Browser into a fresh Pharo 3.0 Image. When selecting "3D IDE" (Roassal3D Easel??) from the tools-menu i got to the following error: MessageNotUnderstood:NBMSAAOffscreenDisplay>>bindFramebuffer. Probably i forgot to load some other base packages. Pharo3.0 Latest update: #30644 Host: OS X 10.8.5 Any hints? Volkert

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
by Tudor Girba Dec. 19, 2013

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? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

[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
by jannik.laval Dec. 18, 2013

Dec. 18, 2013

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 !

Problems with Postmark in Pharo 2.0 with and without Seaside
by Dave Dec. 18, 2013

Dec. 18, 2013

Hi guys, I'm going to crosspost to the seaside and pharo lists, so please forgive me First: I'm stuck in installing Postmark, I think is something wrong with seaside, because on a Pharo 2.0 clean image everything is fine So the scenario is: On Pharo 2.0 and clean image, cmd-p on: Gofer new url: 'http://smalltalkhub.com/mc/PharoExtras/Postmark/main' ; package: 'ConfigurationOfPostMark'; load. (Smalltalk at: #ConfigurationOfPostMark) project stableVersion load. returns: a MetacelloFetchingMCSpecLoader(linear load : explicit load : 1.0 [ConfigurationOfPostMark] load : ConfigurationOfGrease-JohanBrichau.236 explicit load : 1.0 [ConfigurationOfPostMark] load : ConfigurationOfJSON-PaulDeBruicker.3 linear load : 1.0 [ConfigurationOfPostMark] linear load : 1.0.8 [ConfigurationOfGrease] load : Grease-Core-pmm.72 load : Grease-Pharo20-Core-pmm.1 linear load : 1.0 [ConfigurationOfJSON] load : JSON-ul.35 load : PostMark-Core-PaulDeBruicker.15) On Pharo 2.0 and clean image, cmd-p on: Gofer new url: 'http://smalltalkhub.com/mc/PharoExtras/Postmark/main' ; package: 'ConfigurationOfPostMark'; load. (Smalltalk at: #ConfigurationOfPostMark) project stableVersion load. gives me: - a DNU GRPackage(Object)>>doesNotUnderstand: #includesSelector:ofClassName: - then an alert: "You are about to load new versions of the following packages that have unsaved changes in the images: Zinc-FileSystem" I press merge - then another alert: "You are about to load new versions of the following packages that have unsaved changes in the images: Zinc-HTTP" I press merge so finally the result of cmd-p is: a MetacelloFetchingMCSpecLoader(linear load : explicit load : 1.0 [ConfigurationOfPostMark] load : ConfigurationOfGrease-JohanBrichau.236 explicit load : 1.0 [ConfigurationOfPostMark] load : ConfigurationOfJSON-PaulDeBruicker.3 explicit load : 1.0 [ConfigurationOfPostMark] load : ConfigurationOfSeaside3-JohanBrichau.71 linear load : 1.0 [ConfigurationOfPostMark] explicit load : 1.0.8 [ConfigurationOfGrease] linear load : 1.0.8 [ConfigurationOfGrease] load : Grease-Core-pmm.72 load : Grease-Pharo20-Core-pmm.1 load : Grease-Tests-Core-DamienCassou.81 explicit load : 3.0.9 [ConfigurationOfSeaside3] explicit load : 3.0.9 [ConfigurationOfSeaside3] explicit load : 3.0.9 [ConfigurationOfSeaside3] load : ConfigurationOfSPort2-JohanBrichau.12 explicit load : 3.0.9 [ConfigurationOfSeaside3] explicit load : 3.0.9 [ConfigurationOfSeaside3] explicit load : 3.0.9 [ConfigurationOfSeaside3] load : ConfigurationOfZincHTTPComponents-SvenVanCaekenberghe.59 linear load : 3.0.9 [ConfigurationOfSeaside3] linear load : 1.0.8 [ConfigurationOfGrease] linear load : 1.0.8 [ConfigurationOfGrease] linear load : 2.4.6 [ConfigurationOfZincHTTPComponents] load : Zinc-Character-Encoding-Core-SvenVanCaekenberghe.28 load : Zinc-Character-Encoding-Tests-SvenVanCaekenberghe.15 load : Zinc-Resource-Meta-Core-SvenVanCaekenberghe.28 load : Zinc-Resource-Meta-Tests-SvenVanCaekenberghe.16 load : Zinc-FileSystem-SvenVanCaekenberghe.10 load : Zinc-HTTP-SvenVanCaekenberghe.383 load : Zinc-Tests-SvenVanCaekenberghe.199 load : Seaside-Core-pmm.771 postload : Seaside-Core >> seaside304DoIts load : Javascript-Core-pmm.94 load : Seaside-Tests-Core-pmm.258 load : Seaside-Tests-Canvas-pmm.59 load : Javascript-Tests-Core-pmm.68 linear load : 2.33 [ConfigurationOfSPort2] load : FileSystem-Legacy-JohanBrichau.2 linear load : 1.0.8 [ConfigurationOfGrease] linear load : 1.0.8 [ConfigurationOfGrease] linear load : 1.0 [ConfigurationOfJSON] load : JSON-ul.35 load : PostMark-Core-PaulDeBruicker.15) Wow, so many more packages than the clean image! Second: That's not the end of the story, both in Pharo 2 clean image then the image with Seaside, if I evaulate: email := PMEmail new from: 'me(a)me.com'; to: 'you(a)you.com'; subject: 'whatever'; textBody: 'test'; yourself. interface := PMInterface new. interface apiKey: 'my key'. interface send: email. I discover 1) textBody is no more a valid selector (so PMInterface comment is obsolete), I got rid of it and I tried again, but 2) I get an alert: NameLookupFailure: cannot resolve 'api.postmark.com' Gosh! Hints? TIA Dave -- View this message in context: http://forum.world.st/Problems-with-Postmark-in-Pharo-2-0-with-and-without-… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

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
