Pharo Launcher in Windows and Linux
by horrido March 26, 2018

March 26, 2018

I've encountered some issues with Pharo Launcher in Windows and Linux. First, in Windows 7, upon starting Pharo Launcher, you get this: *primitive #createDirectory: in WindowsStore failed* If you push through and create an image and then try to launch the image, you get this: *primitive #primSize: in MultiByteFileSystem failed* Completely unusable. Second, in Linux (Manjaro), if you create an image for *Pharo 6.1 (stable)*, and then launch it, you get this: *FT2Error: Freetype2 primitive failed [error -1][can't get error string]* It seems to be usable, though. The issue does not occur with Pharo 6.0. All of this comes from the latest Pharo download at pharo.org/web/download. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Zeroconf for Windows?
by horrido March 26, 2018

March 26, 2018

The instructions for Pharo Zeroconf scripts seem to be specific to Linux or macOS. How do I use Zeroconf in Windows? I can install curl but there is no bash. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Can I use stateful Traits in Pharo 6.1?
by HernÃ¡n Morales Durand March 25, 2018

March 25, 2018

Suddenly I need a stateful trait and had a quick look at this paper : http://scg.unibe.ch/archive/papers/Verw11bFlexibleObjectLayouts.pdf Is this supported right now? Any code example out there? Cheers, HernÃ¡n

Metacello Platform Packages
by Sean P. DeNigris March 23, 2018

March 23, 2018

I wonder if a best practice has developed here. Mariano had mentioned a while back that he preferred not to have any platform package for latest Pharo, and to implement as necessary to make things work on earlier Pharos. I've used this with good results in the past, but it sometimes gets hairy e.g. if we implement a Calypso shortcut, and Calypso doesn't exist in Pharo###, now we have to implement dummy classes to even make it loadable in those prior Pharos and maybe jump through hoops to hide compatible behavior inside those dummy classes. Thoughts out there? ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Pharo as an advanced desktop with applications
by Hajo Dezelski March 23, 2018

March 23, 2018

)Hello, I must confess that I have not RTFM totally, so when my question has been asked or answered before, sorry. I have been using Smalltalk about 25 years ago and still have the books from Goldberg and Lalonde. But during the time I watched but did not actively follow the development. In the last years I switched to Python using also the NLTK. My main problem is the organisation of information in the form of lots of text objects. Here I used heavily Emacs and the org mode and still my favorite: Scrivener (https://www.literatureandlatte.com/scrivener/overview) I am still looking for an integrated environment to write/organize/analyse text. And I am sure that everything is in Pharo and what is missing can be programmed. I understand that Smalltalk is an IDE, but I haven't been pointed to Pharo as a standard desktop. I found Grafoscopio which seemed to me a basis for the work I do, but still haven't found tools for standard text processing/ file management / dictionary lookup etc. And I am still missing/haven't found working examples in the classes, so that if you are unsure what it really stands for, I could start an example and start digging. As an example until now I was not able to import my org files and see what the parser does. So are there some documents where it is explained where to find an editor, markup-tags, so that I can import my text base and can start playing with my text within Pharo and use it also as a working environment. Thanks in advance Hajo --- Cela est bien dit, mais il faut cultiver notre jardin. http://hajos-kontrapunkte.blogspot.de/

ZnClient - receiving/parsing malformed cookie 'expires' value
by PAUL DEBRUICKER March 22, 2018

March 22, 2018

Hi - This is more of an FYI than anything I'm interacting with an API that is sending "expires=0" value as part of the only cookie of their response. Changing #expiresTimeStamp to (self expires isNil or:[self expires size<28] ) ifTrue:[ ^ DateAndTime now + 1 day ]. ^ ZnUtils parseHttpDate: self expires fixes my issue but maybe there's a better way to handle cookie parsing errors Paul

Problem setting up Tide demo
by in_pharo_users＠nym.hush.com March 22, 2018

March 22, 2018

Hi Esteban, after I got Amber running separately, I set up Tide according to https://github.com/tide-framework/tide readme.md Everything went fine so far, but after the page loaded, Helios did not pop. Blank page. So I looked into the page source and, suspiciously, at line 18 I found **** require( [ "amber/devel", "amber/helpers", "tide/Tide-Amber-Core", "tide/Tide-Amber-Exceptions", "tide/Tide-Amber-Examples", "tide/Tide-Amber-Tests" ], function (smalltalk) { smalltalk.initialize({defaultAmdNamespace: 'tide'}); smalltalk.popupHelios(); } **** I searched for all required paths in the bower path, but could not find only the first two. Can you kindly give me a hint how to proceed to get it running? Kind regards, basket

Issues with recent Pharos reading files
by Andrew P. Black March 22, 2018

March 22, 2018

Iâm having trouble reading files with the most recent âstableâ versions of Pharo. Today, I downloaded Pharo (32-bit), loaded my code into the image using git and Iceberg, and half of my tests failed because Pharo claimed that the files that are on my disk are in a directory that does not exist. If I go back to an older image, everything works fine. Iâm seeing a similar thing on Travis-CI: the build under Pharo 6 works fine, and all the tests are green, but the build under Pharo 7 fails: > Loaded -> SmalltalkCI-Coverage-Core-fn.5 --- filetree:///home/travis/smalltalkCI-master/repository [:] --- cache > SmalltalkCIPharo class>>deprecationWarning (TestCoverage is Undeclared) > SmalltalkCIPharo7 class>>stdout (ZnCrPortableWriteStream is Undeclared) > Loaded -> SmalltalkCI-Pharo-Core-fn.62 --- filetree:///home/travis/smalltalkCI-master/repository [:] --- cache > ...finished baselineMessageNotUnderstood: receiver of "on:" is nil > UndefinedObject(Object)>>doesNotUnderstand: #on: > SmalltalkCIPharo7 class>>stdout > SmalltalkCIPharo7 class(SmalltalkCI class)>>travisFold:id:block: > SmalltalkCIPharo7 class(SmalltalkCI class)>>stage:id:block: > SmalltalkCIPharo7(SmalltalkCI)>>reportImageInfo > SmalltalkCIPharo7(SmalltalkCI)>>basicLoad > [ super basicLoad ] in [ [ super basicLoad ] > on: (Smalltalk at: #MCMergeOrLoadWarning) > do: [ :ex | ex resume: true ] ] in SmalltalkCIPharo7(SmalltalkCIPharo)>>basicLoad in Block: [ super basicLoad ] (The logs are here: https://travis-ci.org/apblack/GraceInPharo. Look at build #83. Iâm not sure if they are public â I think that they are!) Whatâs weird is that my co-worker, who I was introducing to Pharo, was able to download a Pharo distribution and install and run the same git commit with no problems. So I decided that maybe my launcher was out of date. I just downloaded and installed a new version of the launcher. When I use it to create a new image, it is unable to launch it, because it canât find the VM. (The VM package was there, but with a âno entryâ sign across it.) I eventually patch up the launcher by hand, and load my code into a new image. Half of my tests fail once again. There are two issues. First, file streams are now ZnCharacterReadStreams instead of MultiByteFileStreams. Ok, thatâs a change that I had been expecting. But ZnCharacterReadStreams donât understand readStream, whereas MultiByteFileStreams did (and returned self). I can code around that. The second issue is one that I canât code around. Iâm getting a "directory does not existâ error from DiskStore>>#basicEntry:path:nodesDo:, even though the sending method, FileSystemStore>>#directoryAt:ifAbsent:nodesDo: has just correctly verified that the directory does exist. Looking at the offending method, I think that the problem is that Primitives lookupEntryIn: encodedPathString index: index. always returns #badDirectoryPath. Since this method contains a call to a primitive, followed by ^ #badDirectoryPath if the primitive fails, Iâm guessing that either I donât have the primitive installed, or I have an old version of the primitive. How do I fix this? More interesting in some ways: if I download a new copy of the launcher, and then use the launcher to install a new copy of the development image, shouldnât all of the necessary files be installed along with it. >From the fact that this isnât working on Travis either, Iâm guessing that there might be a problem with the distribution.
