[Pharo-project] MC, Ring and RPackage dependencies
by Pavel Krivanek May 9, 2012

May 9, 2012

Hi, I yesterday put Pharo Kernel Gofer 2.0 job into operation (together with some other dependent like Seaside and OSProcess evaluator). But unfortunatelly I have to say it was quite complicated and I had to do some ugly hacks because we do not have solved dependencies between Monticello, Ring and RPackage. The loading order we use now is: 'Monticello' 'MonticelloConfigurations' 'Ring-Core-Kernel' 'RPackage-Core' 'RPackage-SystemIntegration' Authors of this packages should know that this are primitive packages that cannot be loaded in one bundle via Monticello but must be loaded one by one as standard *.st files. That means that that we have to have well known and working loading order. As an example, currently the initialization of the package 'RPackage-Core' is dependent on presence of 'RPackage-SystemIntegration'. Cheers, -- Pavel

[Pharo-project] Improved version of StartupPreferences
by Mariano Martinez Peck May 9, 2012

May 9, 2012

Hi guys. After playing a little bit with StartupPreferences, and continuing the effort of Ben (thanks Ben for yet another great tool), I generate a improved (from my point of view) version of the tool. The main changes are: a) Previously the tool searched files 1) first in image directory, 2) then in the preference folder and 3) finally in the general preference folder. As soon as it found at least one file, I didn't continue with the rest of the places. Now, it starts the other way around, from the most general to the most spceific. Starts in 3), then 2) and finally 3). Moreover, it does not stop when it finds files in any of them. So all are searched and executed. It works or or less the same way as variables in UNIX with .bashrc /etc/envirorment, etc... b) I have created several class side methods (addAtStartup*) to create given actions into the current directory. Previously, files were created in 2 folders at the same time and there were only the possibility to create only in one place. Now you can add startup actions in any of the 3 places mentioned in a) c) Added a whole protocol (remove* and clean*) to remove script files from all folders of a) and also to clean the internal stored actions. d) Lots of internal refactors to reuse code and less hardcoding. Does someone want to take a look to the slice ? Slice in inbox: http://code.google.com/p/pharo/issues/detail?id=5835 Cheers, -- Mariano http://marianopeck.wordpress.com

[Pharo-project] Running in background with OSProcess
by Sean P. DeNigris May 9, 2012

May 9, 2012

How would I run '/usr/bin/java -jar "/path/to/jenkins.war" &' with OSProcess? Specifically I want to know the process number of the java child process. I unsuccessfully tried: * PipeableOSProcess command: '/usr/bin/java -jar "/path/to/jenkins.war" &', which successfully launches java, but I don't know its pid because the returned process is the completed parent "sh" that launched it * PipeableOSProcess command: '/usr/bin/java -jar "/path/to/jenkins.war"' (without ampersand), which also launches successfully, and leaves the parent "sh" process running as well (not as clean), but I still don't know the java pid I then succeeded with: p := PipeableOSProcess command: '/usr/bin/java -jar "/path/to/jenkins.war" & { echo $! ; }'. p output lines first. But this seems convoluted and I'm assuming there must be a simpler way. What is the best way to do this? I.e.: * launch a long running child process * without keeping the sh process open * accessing the pid of the child Thanks, Sean -- View this message in context: http://forum.world.st/Running-in-background-with-OSProcess-tp4615534.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] Unicode/Latin1 handling in Pharo 1.3
by Holger Hans Peter Freyther May 8, 2012

May 8, 2012

Hi, I am trying to read a file from disk that is in latin1 encoding and then try to compare the string with a string provided as literal and it fails. My test case can be seen below. I am using Pharo 1.3 on a Linux machine with a UTF-8 locale. Is there something obvious that I am doing wrong? | stream text | stream := (FileStream fileNamed: 'pharo_example_latin1.txt') converter: ISO885915TextConverter new; yourself. text := stream contents. text = 'TeilrÃ¼ckzahlung'

[Pharo-project] How to dispatch mouseWheel?
by Martin Drautzburg May 8, 2012

May 8, 2012

Hello all, I've been happily using #handlesMouseWheel: and #mouseWheel until I had to "ousource" parts of my Morph to a Submorph for layout reasons. The part which shall respond to mouseWheel is no longer the Morph itself but a Submorph thereof. Of course this Submorph does not respond to mouseWheel, because all the wheely stuff is defined at class level in its owner's class. So I thought I could just tell this stupid little Moph to let its owner handle the mouse stuff. But there does not seem to be a way to use on:send:to with mouseWheel. Is there a way around this problem. Or is there another way to "just do layout" whithout interfering with the event handling? -- Martin
