funny idea Symbol vs. Selector
by stephane ducasse May 14, 2015

May 14, 2015

Hi guys I'm thinking aloud... I was wondering if we could not take advantage of a new class: Selector. MethodDict would only contain selectors and not symbols. I remember that I talked about that with hernan. Stef

Postmark email library
by Francois Stephany Aug. 31, 2013

Aug. 31, 2013

Hi guys, I've made a simple wrapper around the Postmark API. It lets you send emails without dealing with a SMTP server. You can read about it here: http://developer.postmarkapp.com/developer-libs.html http://developer.postmarkapp.com/developer-build.html and there: http://articles.tulipemoutarde.be/send-email-from-pharo-with-postmark It's pretty simple and naive implementation but it gets the job done. I'll add email attachements when I will need it. Francois

Package browser?
by Rob Vens June 28, 2013

June 28, 2013

I am attempting to do the Pharo by Example book, but a package browser (which is used in the examples) is not in the 1.1.1 or 1.2 image. Should I still use categories? If I create a package in Monticello browser I am not able to add classes or anything (not as far as I could see). Just starting out using Pharo, so apologies if these questions are already answered elsewhere.

Zinc crashes an image.
by Paul DeBruicker Sept. 25, 2012

Sept. 25, 2012

Hi - I'm pretty sure I'm having the same problem Phillipe had/described in this message: http://forum.world.st/Zinc-crashing-image-at-start-up-td3785797.html At least the PharoDebug.log is the same. It happens on both the most recent Cog and interpreter VM. Is there a way to recover from this? I could follow Sean's instructions from this thread if necessary: http://forum.world.st/Fwd-Oops-I-put-a-halt-in-a-startup-method-td3800729.h… Or is there a way to extract changes from a changes file for one image into another image? I'd rather fix the broken image but if its not possible I'd then just try to load those changes I don't have. Thanks for any guidance you can provide. Paul

Pharo Morphic View Application Framework
by S Krish Feb. 4, 2012

Feb. 4, 2012

http://skrishnamachari.wordpress.com/2012/01/31/pharo-application-framework… Obliged for feedback ... For details and links.. Sharing this little framework that should go some way to ease creating large applications ( currently morphic oriented). AbstractMorphicView subclass: #MyNewView â¦ #createMorphsSpecs ^{ âpanel1â² -> #SomeOtherView. âlabel1â² -> #LabelMorph. âtext1â² -> #PluggableTextMorph. âbutton1â² -> #PluggableButtonMorph. } layoutSpecsArray ^{ âwidgetNameInMorphsDictionaryâ -> { #fractions -> (0 @ 0 corner: 1 @ 0.5). â fractional value 0 to 1 range â #offsets -> (10 @ 10 corner: 0 @ 0). â offsets relative to the fractional position â }. ââ¦ add other widgetspecsâ¦â } Thats it.. you should have a prototype UI neatly laid out.. and then specify: #morphsPrimaryPropertiesSpecs and #morphsSecondaryPropertiesSpecs for full functionality that composes views inside views and scales well. AbstractSimpleMorphicView can make it simpler for TableLayout stuff without requiring #layoutSpecsArray. ..... the main post has other details and links to package...

Command Line Interface using FFI
by Guillermo Polito Jan. 30, 2012

Jan. 30, 2012

I've spent a few hours playing with Alien+FFI and I did want to have a Command line interface to play and use as a quick browser. Gofer it squeaksource: 'CLInterface'; package: 'ConfigurationOfCLInterface'; load. ConfigurationOfCLInterface load. To play with it write a script, for example startCLI.st, with the following: *CLInterface start* And then, from the command line CogVM -vm-display-null <image> startCLI.st What it does support? - executes smalltalk expressions - handles the errors and shows them into the stdout (so it does not explode :P) - stores variables as a workspace Since I used standard C functions (fgets and printf only) this should work on every platform from scratch (having a VM with FFI working, of course)... The problems I've ran so far: - blocking FFI blocks the vm. I've not tried yet to use threads through FFI (and I don't know if it works. Does it?). But It should be great to start a headless seaside server with a command line :/. Ok, it's a very simple thing, but it allows to execute a expression from a remote server via ssh without doing much :). Guille

Fwd: [Pharo-project] Pharo sprint in Brussels on Feb 4th
by Mariano Martinez Peck Jan. 27, 2012

Jan. 27, 2012

---------- Forwarded message ---------- From: Andy Kellens <akellens(a)vub.ac.be> Date: Fri, Jan 27, 2012 at 11:35 AM Subject: [Pharo-project] Pharo sprint in Brussels on Feb 4th To: Pharo-project(a)lists.gforge.inria.fr Dear Pharoers, In an earlier mail Stephan Eggermont already mentioned that there will be Pharo sprint collocated with the FOSDEM conference next week. This sprint will take place on Saturday February 4th from 10h until 18h in the rooms of the Software Languages Lab of the Vrije Universiteit Brussel. More precisely: Room 10F720 (10th floor of building F) Vrije Universiteit Brussel Pleinlaan 2 1050 Brussels Due to renovations to our building, you will have to enter via the entrance between buildings F and G. As the university is normally closed on a Saturday, you might have to pass via security in order to be allowed entrance to the building (they have been notified about the sprint). If you are coming by car, please send me your license plate so that I can make sure that you are allowed to enter the campus. To get some idea of how many people to expect, could you please let us know if you are planning to attend. Kind regards, Andy -- Mariano http://marianopeck.wordpress.com

Hi list, Is there an Actors library already available in Pharo? The part I'm interested in is the asynchronous message passing. If it has been done already, why not reuse? Thanks in advance!

SpellingPlugin
by Paul DeBruicker Jan. 18, 2012

Jan. 18, 2012

Hi - Where can I read more about the SpellingPlugin thats included with the Mac VM? I'm hoping to learn whether it uses the hunspell library and if so whether the plugin can be made to run on linux, and if so can then be incorporated as the spell checker for the lint rules as well as for Seaside components/user input. Thanks Paul

First steps making OB work in 1.4
by Guillermo Polito Jan. 17, 2012

Jan. 17, 2012

Hi! I've been working the last days in making OB work in pharo 1.4. I updated several deprecations like method reference and stuff and discovered some bugs that I've already published in: http://code.google.com/p/pharo/issues/detail?id=5189&q=milestone%3D1.4&cols… http://code.google.com/p/pharo/issues/detail?id=5183&q=milestone%3D1.4&cols… I've already proposed some fixes for them, but if anyone can have a look too I'll feel better :). Those fixes are needed in order to load OB. Meanwhile, you can also have some patches from the cs and fileout I attach. What's working now? OB + OCompletion + Shout + Sunit integration. So, It's everything but Refactoring browser, which is a little more difficult since there is another RB version loaded in the image :P. To load it (after integrating the patches): Gofer it squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfOmniBrowser'; load. (ConfigurationOfOmniBrowser project version: #stable) load: #( 'Core Tests' 'OCompletion Tests' ) , #( 'Core' 'OB-SUnitIntegration' 'OB-Shout' 'OCForOB'). Cheers, Guille

How to get the widget with focus?

Jan. 16, 2012

Hi all, I am writing some test cases that require me to open and close windows and play with widgets and whatnot. Sadly I am a bit lost as I have no experience in this area. Now I am trying to get a handle on the widget that has focus. Is there an easy way to get to this widget? Also some pointers to examples/tests that programmatically operate on widgets and could serve as examples would be appreciated.

compression example?
by Larry White Jan. 13, 2012

Jan. 13, 2012

Hi, I'm trying to read the files in a given directory, add them to a ZipArchive, and write that ZipArchive out to another directory. My code looks like this: zip := ZipArchive new. zipArchive addDirectory: '/Users/data/files/arabic' as: 'arabic'. fileName := 'Users/data/downloads/foo.zip'. zip writeToFileNamed: fileName. I'm getting an archive file with the correct name written out, but I can't access the contents of folder 'arabic'. Do I have to add each of the files in 'arabic' explicitly to the zipArchive? Does anyone know of some example code for this they could point me to? Thanks much and happy new year. Larry

another confusing result
by Larry White Jan. 9, 2012

Jan. 9, 2012

This may just be me misunderstanding the way it's supposed to work, but I was exploring the method combinations: kk atATimeDo: aBlock defined in SequenceableCollection 'abcde' combinations: 2 atATimeDo: [:each | Transcript cr; show: each printString]. produces the expected result: #($a $b) #($a $c) #($a $d) #($a $e) #($b $c) #($b $d) #($b $e) #($c $d) #($c $e) #($d $e) but, if you add :each to a collection instead of printing, you get something different. The following code: res := OrderedCollection new. 'abcde' combinations: 2 atATimeDo: [:each | res add: each]. Transcript show: res. produces: an OrderedCollection(#($e $e) #($e $e) #($e $e) #($e $e) #($e $e) #($e $e) #($e $e) #($e $e) #($e $e) #($e $e)) Thanks again.

strange behavior in workspace
by Larry White Jan. 8, 2012

Jan. 8, 2012

I'm messing about with Project Euler problems and have noticed some behavior that I don't understand. This one happens to be very self-contained so I though I'd as for assistance. This code (which doesn't solve the problem, btw) is buggy, but I can't see the bug and I'm beginning to suspect something in the VM or the class libraries. When I execute it, two odd things happen: First, in spite of the block test [sum < 100] whileTrue:[...] it continues to run when sum > 100 (or a million for that matter). Second, the block in the line: (sum isPrime) ifTrue: [ (seq size > bestSeq size) ifTrue: [ bestSeq := seq copy.]] executes even when sum is not a prime number. Any help is appreciated. ------------------------------- "Create a list of primes smaller than a million" primes := OrderedCollection new. 2 to: 999999 do: [ :n | n isPrime ifTrue: [ primes add: n]]. bestSeq := OrderedCollection new. seq := OrderedCollection new. sum := 0. [sum < 100] whileTrue: [ primes do: [:prime | seq add: prime. sum := seq sum. (sum isPrime) ifTrue: [ (seq size > bestSeq size) ifTrue: [ bestSeq := seq copy.]] ] ].

compressing multiple files in Pharo
by Larry White Jan. 8, 2012

Jan. 8, 2012

Hi, I'm trying to help a friend with her non-profit website. She needs to be able to bundle files into a single file for easy downloading (and easy unpacking on the client). The files are pre-compressed sound files so further compression isn't really needed or useful. My first attempt used ZipArchive, which seemed to write ok, but I can't decompress it. (I tried to describe that problem in another email.) I'm now trying to compress more than one file to a GZipWriteStream. I copied and modified the code in the compressed method on FileStream to look like this: compressFiles "Write a new file that has the data in files compressed in GZip format." | zipped buffer file dir | dir := self directoryFor: 'hgo' language: 'arabic'. zipped := dir newFileNamed: ('foobar', FileDirectory dot, 'gz'). zipped binary; setFileTypeToObject. zipped := GZipWriteStream on: zipped. dir fileNames do: [:fName | file := FileStream fileNamed: fName. file readOnly; binary. buffer := ByteArray new: 50000. [file atEnd] whileFalse: [ zipped nextPutAll: (file nextInto: buffer)]. file close.]. zipped close. ^zipped It doesn't work. It seems to compress the first file ok, but the others aren't included. Is there a reliable way in Pharo to solve the underlying problem of packing multiple binaries into a single file? thanks much.

Call for translation
by Hilaire Fernandes Jan. 7, 2012

Jan. 7, 2012

Hello, Dr. Geo (http://www.drgeo.eu) is a neat open source application showing the power of Pharo Smalltalk. It is targeted to teachers, parents and kids for all over the world. It is distributed as a portable desktop application and also a XO application for the OLPC kid laptop. As for now it is translated in English, French, German and Spanish. I would love to see more translation from the European house (latin alphabet based, there is still investigation to be done for non latin language). Italian, Portuguese, Swedish, Finland, Dutch, Norwich, Danish... will be nice Translating DrGeo is less than one hour of work[1].

Hi! I'm willing to announce the second beta release of Phoseydon, part of the DBXTalk project, supported by ESUG :). It's main new feature is a simple internal dsl to generate entities, so you can create applications from something like: personEntity := application entityNamed: #Person. personEntity hasString: #nickname; hasInteger: #age; hasBoolean: #isProgrammer. petEntity := application entityNamed: #Pet. petEntity hasString: #nickname. personEntity hasMany: #Pet as: #pets. petEntity hasOne: #Person as: #owner. Also, a little manual is already written in: http://dbxtalk.smallworks.com.ar/pier/Documentation For download: http://dbxtalk.smallworks.com.ar/pier/Download Issues, mails, questions: http://dbxtalk.smallworks.com.ar/pier/Support Cheers, the DBXTalk Team

Interpreting a crash.dmp file was: Re: [Seaside] Seaside image health check

Thanks Levente. I have an image that stops responding to seaside requests and maxes out the CPU. This happens after a random amount of time generally longer than a day. Sometimes I can get it to pop out of the hang by signing in through the RFB server, but sometimes not. In this Pharo-1.3-13315 image (Ubuntu 64bit, Cog 2522 from Eliot's site) I'm using RFB and have applied the fixes described here: https://code.google.com/p/pharo/issues/detail?id=4829#c6 I think that the crash.dmp file shows that the image was stuck trying to create an IdentitySet from an array. Maybe I need to take a sample of the "kill -USR1 <pid>" commands to know for sure. The other thing that's weird is that in the crash.dmp file I don't see the Seaside server process. I'm using Comanche as the server adapter. Is there anything I should look for in my application or image to get more info about the disruption in processing requests? Thanks Paul
