EXIF / JPEG metadata
by Alistair Grant Nov. 30, 2025

Nov. 30, 2025

Hi Everyone, As far as I can tell, JPEGReadWriter in Pharo 7 doesn't read (or write) the image metadata, e.g. title, keywords, exposure time, etc. Is anyone aware of a package that does? Thanks! Alistair

Re: [Pharo-users] Personal wiki / information manager

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. Kind Regards TedvG

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 >

Parsing in VW
by Steffen MÃ¤rcker Dec. 3, 2019

Dec. 3, 2019

Dear all, I have two questions regarding parsing frameworks. 1) Do you have any insights on the performance of SmaCC VS Xtreams Parsing VS PetitParser? 2) Has anybody started to port PetitParser 2 from Pharo to VW? Is it worth the effort? Sorry for cross-posting, I thought this might interest both communities. Cheers, Steffen

Microsoft COM
by Ben Coman 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

Mindmaps and WardleyMaps in Pharo
by Rafael Luque Aug. 1, 2019

Aug. 1, 2019

I'm looking for drawing some mindmaps and (obviously) I'd like to be able to draw and visualize them inside my own Pharo tools. I've found this video in Stephan Eggermont's channel: https://vimeo.com/136943448 Do you know any other alternatives for Pharo? BTW, I also found this other video about Wardley maps: https://vimeo.com/141653455 I found it very interesting. Somebody knows where can I find this project? Thank you!

How to visit over packages, classes, methods (all types)
by Tim Mackinnon June 17, 2019

June 17, 2019

Hi - is there a way to iterate over all the code in a package (or class or baseline) in a generic way (to pretty print out class definitions, and methods - including extensions ). I was kind of hoping that with TonelWriter and Fileout and Critics that we would have a generic visitor mechanism but it seems that all of them just implemented it again - which misses a big opportunity for refactoring so that when you want to reason/print/manipulate code - it would be more straight forward. Is there anything/anyone addressing this ? Or maybe Iâve missed an obvious trick somewhere? Tim Sent from my iPhone

Introduction GSoC 2019
by Nina Medic June 17, 2019

June 17, 2019

Hello, I am Nina, and I am a student from Serbia. Currently I am on the second year, of my master studies in Computer science. I have been working with Pharo for more than a year now. As a project in one of my classes, I was implementing a program that parses graphs and makes a visualization of them. Last semester I followed MOOC for Pharo. A couple of days ago, I was fortunate enough to be accepted for this year Google Summer of Code. The project I will be working on is called *Graph library with layouting algorithm*. What I will do is implement the graph structure with all necessary parts in one separate library. Beside that I will include layouthing algorithms. Some of which are already implemented as a part of some other projects and packages, those I will pull out. For the other ones, I will be using doctoral dissertation from Vaderna Renata titled *Algorithms and a language for the support of automatically laying out diagram elements*. You can find my proposal here: https://docs.google.com/document/d/1V8_HaZnxYsCfaiZs4vI1C5Dh4TvRPz-H51aYOuY… I would like to know, what are you thinking about this project. How important is for the community? One of fellow students from GSoC (we are both working for Pharo consortium) and I are considering using the same blog. What do you think about that? I will be also posting about my progress on Twitter: https://twitter.com/medicka992 which will make it easy for everybody to follow my work. I am looking forward to working on this project and with all of you. Sincerely, Nina.

Block/Brick
by Steve Quezadas June 4, 2019

June 4, 2019

I am trying to experiment with Bloc and Brick. I downloaded the packages, and want to "play around with it" by experimenting with the examples in it. But how do I open the examples? The github page for both Block and Brick doesn't really list much documentation. Taking from an arbitrary Brick example, these things don't work: foo := BrExamplesShowroom new. foo openInWorld. - or - BrExamplesShowroom openPlayer Sorry for the naive quesiton. - Steve PS Is Brick/Block the thing to learn these days? Is this where development is heading?
