Seems that Pharo is a magnet for this kind of project. I've been writing one as well and using it to organize my research notes. Does anyone working on personal info mgmt tools want to talk offline? I expect we're running into some of the same issues, both conceptual and technical. Evan

Pharo 6.0 and 6.1 64 bit freeze on MacMini
by Ted F.A.van Gaalen Jan. 27, 2020

Jan. 27, 2020

Hi, I reverted to 5.0 because Pharo 6.0 and 6.1 64 bit hangs on my Mac Mini with UDH 4K screen (may that has to do with?) with its maiden image (at first start after download when: I resize or go to full screen. Maybe VM problem? my mac Mini metrics: Hardware Overview: Model Name: Mac mini Model Identifier: Macmini6,2 Processor Name: Intel Core i7 Processor Speed: 2,6 GHz Number of Processors: 1 Total Number of Cores: 4 L2 Cache (per Core): 256 KB L3 Cache: 6 MB Memory: 4 GB Boot ROM Version: MM61.0106.B1F SMC Version (system): 2.8f0 maybe this problem was already reported, but could find it.

It seems the > only questions have been: 1) how to do them *right*, The default position would be leveraging someone else's experience, so this begs the question, what is wrong in namespace implementations in VW, Gemstone, Squeak (as our immediate neighbours, then plus Dolphin, SmalltalkX, other languages) Are there been any research papers around comparing these? I found the "Pharo on Gemstone VM" talk impressive. The "develop on Pharo deploy on Gemstone" philosophy seems like a nice synergy for Pharo's commercial future. So a naive approach would be to do namespaces just like Gemstone. Maybe its not the best, but would it be "good enough" -- perfection being the enemy of done and all that jazz. cheers -ben > and 2) where they fall on the endless prioritized todo list >

Microsoft COM

Sept. 27, 2019

Hi Pablo, At work I managed to remote control Internet Explorer with Excel VBA like this... [1] http://www.automateexcel.com/vba/automate-internet-explorer and went looking for how similar might be achieved from Pharo. IIUC I discovered this would be done via Microsoft's Component Object Model, and then I bumped into your repo... [2] https://github.com/tesonep/pharo-com Could you advise the status and your plans for this? Since I see its only a few months old I've probably stumbled onto it prematurely, but I see no documentation or tests to discover how to use it. So I'll curious whether it makes something like [1] possible? And could you show how that would be done? cheers -ben P.S. For context, at work I automated IE since the intranet document management system (OpenText) does authentication via a javascript function in the browser, which doesn't compute with Microsoft's MSXML.DOMDocument component. So I use IE to do the authentication and grab the raw XML from IE to then stuff it into MSXML.DOMDocument from which I pull the data I need. But I'd love to do it with Pharo instead (if I can get IT to white list it) cheers -ben

Calypso question: adding a context menu item
by Juraj Kubelka March 16, 2019

March 16, 2019

Hi, To implement a context menu item. I have implemented a new class: -=-=-=- CmdCommand subclass: #ClyHelloCommand instanceVariableNames: '' classVariableNames: '' package: 'Calypso-Extensionsâ -=-=-=- with methods: -=-=-=-=- ClyHelloCommand class >> #systemBrowserMenuActivator <commandActivator> ^CmdContextMenuCommandActivator byRootGroupItemFor: ClyVariableSystemBrowserContext ClyHelloCommand >> # defaultMenuItemName ^'Say Helloâ ClyHelloCommand >> # execute self inform: 'Hello' -=-=-=-=- But it does not display in the context menu. I expect it next to âGenerate accessorsâ as I took this command as an example. What do I miss? Thanks, Juraj

Aggregation framework in MongoTalk?
by phil＠highoctane.be Feb. 18, 2019

Feb. 18, 2019

Is there anyone using the aggregation framework of MongDb through MongoTalk? It uses the aggregate() command, so I was wondering if this could be supported out of the box or if there is a need for an additional Operation. TIA Phil

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

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.
