Test for Voyage failure to materialize in some situation
by Hilaire March 13, 2017

March 13, 2017

Hi , Here is a test case to expose the materialization problem I discussed previously[1]. Hopefully the test will help to track the problem. Note: With memory repository it is of course fine, so MongoDB resource is needed for the test. Hilaire http://forum.world.st/Voyage-and-instances-retrieving-tt4936868.html -- Dr. Geo http://drgeo.eu

[Help Wanted] moderators for pharo mailing lists
by Marcus Denker March 13, 2017

March 13, 2017

Hi, The two Pharo Mailinglists (pharo-dev and pharo-users) are run using Mailman via a commercial provider. (Thanks to the Pharo Association, https://association.pharo.org <https://association.pharo.org/>) This means that we have nothing to do with regard to technical problems/issues or running the service itself. but nevertheless, there are 1-2 emails per month that end up in a moderation queue, mostly because they are very very large. It would be nice to have 1-2 people more to help with these (infrequent) moderation calls. If you are interested to help â> send a mail to me. Marcus

Working bash command fails with OSSubprocess depending on input file
by Silas Berger March 13, 2017

March 13, 2017

Hi everyone, Iâm currently having problems with executing bash commands through OSSubprocess (version: #stable, as of today) on OS X 10.11.6. Iâm using the command line tools of a program called ParseCit to extract metadata from .txt files. It works well for about 75% of all txt files Iâve tested it with, but fails on the remaining 25%. This isnât due to ParseCit though, since it works on all input files, when I issue the command directly from a bash. Iâve prepared two test txt files â one that works fine (goodExample.txt) and one that doesnât work (badExample.txt) with OSSubprocess. The conversion for both files works fine when issuing the following respective commands in a shell or bash: /Users/silas/Documents/TestWithOSS/tools/mac/parsecit/bin/citeExtract.pl -m extract_all /Users/silas/Documents/TestWithOSS/test_txt/badExample.txt /Users/silas/Documents/TestWithOSS/tools/mac/parsecit/bin/citeExtract.pl -m extract_all /Users/silas/Documents/TestWithOSS/test_txt/goodExample.txt Using OSSubprocess, it works well for goodExample.txt, the result looks like this: Unfortunately, that exact same method/command fails, if the target file is badExample.txt instead. Below, you can find two methods Iâve tried for badExaple.txt, neither of which work. Method 2 (which is the one I used in the above screenshot for goodExample.txt) has a stderr stream, its contents are just above the Method 2 screenshot. It looks like it should be a ParseCit problem, but, as Iâve mentioned above, it works fine when done directly in a bash or shell. In this GitHub repo there are the âtoolsâ folder containing a compiled version of ParseCit, a corresponding INSTALL.md with all the necessary install steps for ParseCit, and a folder âtest_txtâ, which contains goodExample.txt and badExample.txt. The EES-INSTALL.md in the same repo is not relevant in this context. If anyone has an idea what could be the problem or how I could get it to work, Iâd be very happy. Best, Silas *** Methods Iâve tried *** Method 1 Result: Empty stdout, empty stderr, exit status 65280 Method 2 Result: Empty stdout, exit status 65280, Stderr: /Users/silas/Documents/TestWithOSS/tools/mac/parsecit/bin/sectLabel/genericSect/extractFeature.rb:35:in `split': invalid byte sequence in US-ASCII (ArgumentError) from /Users/silas/Documents/TestWithOSS/tools/mac/parsecit/bin/sectLabel/genericSect/extractFeature.rb:35:in `<main>' Die: SectLabel::Controller::getGenericHeaders different in number of headers 8 vs. the number of generic headers 0 *** The commands *** p1 := OSSUnixSubprocess new command: '/Users/silas/Documents/TestWithOSS/tools/mac/parsecit/bin/citeExtract.pl'; arguments: #('-m' 'extract_all' '/Users/silas/Documents/TestWithOSS/test_txt/badExample.txt'); redirectStdout; redirectStderr; runAndWaitOnExitDo: [ :process :outString | outString inspect ]. p3 := OSSUnixSubprocess new shell: '/bin/bash' command: '/Users/silas/Documents/TestWithOSS/tools/mac/parsecit/bin/citeExtract.pl -m extract_all /Users/silas/Documents/TestWithOSS/test_txt/badExample.txt'; redirectStdout; redirectStderr; runAndWaitOnExitDo: [ :process :outString | outString inspect ].

Need help opening image
by David Shaffer March 13, 2017

March 13, 2017

I have an image (from Pharo3.0) which reports version 6505. I have tried four OSX vms but none of them will open it. Either I get âThis interpreter (vers. X) cannot read image file (vers. 6505)â or I get hit with a long stream of: [NSPathStore2 stringByAppendingPathExtension:]: cannot append extension 'bundle/Contents/MacOS/' to â¦ which I know is a known bug. The problem is, I canât find a VM that doesnât have this bug but can open my old image format (on OSX). Any pointers would be appreciated. Thanks! David

Spec way to embed something into Scrollable Wrapper
by Peter Uhnak March 12, 2017

March 12, 2017

Hi, is there a Spec way to take something and embed it into scrollable pane? I haven't seen anything like that in Spec itself (List/Tree that has scrollbar has it on Morphic side); but maybe there is a way to embed Spec inside some Morph and then embed the Morph back into Spec? Obviously that's awful, but if someone can point me to a Morphic solution I could try to make a Spec adapter for it. Thanks, Peter

[Pillar dev news] cleaned commandline logic
by stepharong March 12, 2017

March 12, 2017

Hi I started a new branch for Pharo 60. Past actions for this branch are: - clean and document the commandline logic and API in 4.0.11 - extract an object from the commandLine logic so that we can now invoke the logic without having to do it from the image. Next actions: - avoid as much as possible to use DNU trick combined with magritte description for CocoonConfigurations may be one idea is to have a configuration without Magritte and a subclass with. Also a configuration does not have to have per se file support Should check in the future the stylesheet of artefact and extract a common property collection with lookup little framework. - fix problem with some classes trashing printOn: (super cool for debugging) and testing. - start to remove the metadata section (far too complex).

How to use the serial port on MacOS X?
by olivier auverlot March 12, 2017

March 12, 2017

Hi, I try to use the serial port to communicate with an Arduino. On Linux, no problemo. I can open the serial port with the following code: | serialPort baudRate comPortNumber | baudRate := 31250. comPort := '/dev/ttyACM0'. serialPort := SerialPort new baudRate: 31250; dataBits: 8; stopBitsType: 1; parityType: 0; yourself. "the port is closed to ensure that it will be free" serialPort close. (serialPort openPort: comPort) isNil ifTrue: [ ^self error: 'COM port not available' ] ifFalse: [ serialPort inspect ]. serialPort close. But on MacOS X (10.11.6), the same code used with /dev/cu.usbmodel1411 doesn't run. The error is "Cannot open '/dev/cu.usbmodel1411'". I'm sure that is the correct serial port. If I type "more -f /dev/cu.usbmodel1411" in a terminal, the rx/tx leds of the Arduino are blink. Someone has an idea about this problem that is not specific of the Arduino but concerns the generic usage of the serial port with Pharo? Best regards Olivier ps: I can't test on Windows but I'm interested by a feedback.

I have a simple one, but i need to understand what is going on.. i have something like Tree with a class method trees ^ trees ifNil: [OrderedCollection new] i initially ran into trouble with it locking my image up because i wrote it as: trees ^ self trees ifNil: [OrderedCollection new] what is the semantic difference between these two calls?

GitFileTree repository creation crashes Pharo
by Jan BlizniÄenko March 12, 2017

March 12, 2017

Hello I decided to give another try to GitFileTree. My last try was 2 years ago, but I had to revert to simple filetree because of frequent crashes while saving to gitfiletree repository on Windows. Today my attempt ended much more quickly. What I did and what was the result? 1) Downloaded Pharo 5 for Windows from http://pharo.org/download and opened it 2) Found GitFileTree, selected Install stable version and confirmed I want to install although it was not tested for Pharo 5 -> it loaded without visible problem 3) Opened Monticello, +Repository, selected empty directory I just created, clicked Ok -> image closed (like if I killed Pharo process - no error, no question, just closed) So, I am not even sure how to even debug it. Is this any common problem or did I miss something? I tried it also in latest Pharo 6, I tried also loading using code from github://dalehenrich/filetree:pharo6.0_dev/repository , I tried also latest VM, but no luck so far. I have Windows 10 64bit. Thank you Jan -- View this message in context: http://forum.world.st/GitFileTree-repository-creation-crashes-Pharo-tp49382… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
