Pharo 6 snap package
by Alistair Grant Sept. 20, 2018

Sept. 20, 2018

Hi Everyone, I've updated the Pharo 6 snap package for Ubuntu. The major advantages of using the snap package are: - No need to install all the 32 bit dependencies on a 64 bit system, they're all contained and isolated within the snap package. - Automagically distinguish between 32 bit and 64 bit images and run the appropriate VM (as with the ZeroConf package, the 64 bit VM still needs more testing). To get Pharo up and running on Ubuntu 16.04 or later: # Install Pharo $ sudo snap install --candidate pharo --classic # If your system isn't configured for threaded heartbeat: $ sudo pharo.config # Download the latest Pharo 6 image $ pharo.getimage # Go... $ pharo.ui Pharo.image # or: $ pharo Pharo.image eval 4+3 To get a list of available commands: $ snap info pharo If you're on Debian or Ubuntu 14.04 you'll need to install snapd, see https://snapcraft.io/docs/core/install The VM is the threaded heartbeat, dated 201705310241. The installation flags are: --candidate - The edge and beta channels are for development versions. It progresses to candidate and then stable. --classic - Snap packages are normally sandboxed for security reasons. Since Pharo is a development environment in which we want to be able to run any executable, or load any library, it is installed with access to the entire system (as the running user). Why use snap packages? - They include all dependencies. In particular, for the 32 bit versions, this means that it isn't necessary to install all the 32 bit architecture and associated dependencies. - Including dependencies means that there shouldn't be any problems with incompatible library versions when upgrading. Why not use snap packages? - It's a relatively new technology, with a number of rough edges. - There may still be issues with its sandboxing that I haven't discovered yet. - Because the package uses classic confinement, it isn't cross-distribution in practice (unfortunately). Please let me know of any other advantages or disadvantages you think should be listed here. If you don't trust me to configure your system correctly (which requires sudo): - All the scripts that make up the sub-commands are visible, e.g. pharo.config can be viewed at /snap/pharo/current/usr/bin/CONFIG The packaging code is at: https://github.com/akgrant43/pharo-snap Cheers, Alistair

Retina support in Pharo
by markm Sept. 20, 2018

Sept. 20, 2018

Hi Is it possible to get Pharo (4 or 5) to run with retina support on OS X? I have tried searching for some answers, but alas could only find a handful of posts from a few years back. Any help much appreciated! Mark -- View this message in context: http://forum.world.st/Retina-support-in-Pharo-tp4895245.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

safely determining whether ProcessWrapper process is running
by Peter UhnÃ¡k Aug. 3, 2018

Aug. 3, 2018

Hi, I feel like I am missing something obvious, but is there a _safe_ way to test if PW is still running? If the process pointer for whatever reason is no longer valid (e.g. the image crashed / I closed image), then #isRunning results in crashing the image. Maybe this is a bug? Thanks, Peter

Hi folks, does anyone know how to get OmniBase for Pharo 6?. The Package on Pharo.org is for pharo 4, I tried to install them manually from the MCZ files, but I get a strange error in a closeHandle method. <apicall: Literal constant expected -> ulong 'CloseHandle' (long) module:'kernel32.dll'> ^self externalCallFailed. I am using win 7. Thanks. Matias.

Howto BaselineOf

Hi, I have this enclosed BaselineOfDrGeo which I think contains mostly all I need. How should I load it? This code bellow does not work: (BaselineOfDrGeo project version: #development) load. By the way the PharoDebug log file is not recorded along the image, but at the user root directory. Is itÂ wished? ... -- Dr. Geo http://drgeo.eu

pharo bash script with startup
by Otto Behrens July 17, 2018

July 17, 2018

Hi, I just installed pharo 6.1 using the .zip file ( http://files.pharo.org/platform/Pharo6.1-64-linux.zip) and battled to start up pharo with arguments. The issue is that the pharo bash script (in the extracted home dir) quotes all arguments: # execute exec "$LINUX/pharo" \ --plugins "$LINUX" \ --encoding utf8 \ -vm-display-X11 \ "$image" where image = $* The impact is that if I want to run a startup script, eg. pharo my.image startup.st pharo complains with "Could not open the Pharo image file: 'my.image startup.st' So I must run the executable directly? If so, some questions about the options that the bash script passes in: --plugins "$LINUX" is this necessary? will the default not be enough? --encoding utf8 the usage output says for example --textenc default is "UTF-8". Is utf8 the same thing? -vm-display-X11 I tried starting without this, and it worked. Do I need to explicitly start with this? Thanks Otto

Smalltalk Programming Competition
by horrido July 16, 2018

July 16, 2018

FYI, I am trying to jumpstart a Smalltalk programming competition. Read all about it here. <https://medium.com/@richardeng/smalltalk-programming-competition-2be77cab0e…> My plan is to use Pharo for this competition, even if it makes companies like Cincom and Instantiations unhappy. Any support this competition can receive would be greatly appreciated. -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Some facts and figures about pharo gaining momentum?
by Andrei Stebakov July 6, 2018

July 6, 2018

Hi! Do we as a community have some proofs in numbers that the popularity of smalltalk grows? I saw some articles that have some proofs that smalltalk is on the rise, but for my presentation I'd like to back it up with some numbers if possible. You know, it's one thing when you preach to the choir but quite another when you talk to some die-hard Java or JavaScript devs! Any ideas about some great convincing material is also very welcome!

Its too hard to contribute to the Iceberg wiki
by Tim Mackinnon July 5, 2018

July 5, 2018

Ok - my love affair with Github ends at the wiki - what a load of $%$%^$%â¦ there is no sane and easy way to fork a wiki, make some changes and then submit a PR. (how the hell did they get into that state?). Can we agree to scrap the wiki Iceberg wiki and just have a longer readme.md (with sections of the current wiki?). Or if someone can explain easy instructions for both me (as a contributor) and the admins of iceberg then Iâm all earsâ¦. If not - Iâll submit a PR with my subtle changes to the readme. Tim
