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

The System Browser has recently started showing 2 comments tabs - one is text and one is formatted pretty. That seems odd and is not wanted - has anyone else seen this? Pharo 10 stable image - windows 64 - all reloaded recently...

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

UK Smalltalk User Group meeting - Wednesday 29th March
by Giovanni Corriga March 21, 2023

March 21, 2023

This month's online meeting introduces a new format whereby we'll give space to commercial companies to discuss how they make use of Smalltalk and contribute to the Smalltalk community. The first of this series will be Mercap Software ( https://www.mercapsoftware.com/en/ ), represented by Gabriel Cotelli, InÃ©s Sosa, IvÃ¡n Boaretto, MatÃas Fernandez, and Maximiliano Tabacman. During this talk, Mercap will showcase five of their solutions designed for different types of investors. They will shed light on how Mercap benefits from the open-source projects maintained by the Buenos Aires Smalltalk group on GitHub. They will share with you how they use these freely available frameworks to interact with databases, operate on math and time units, create custom CSS, declare interactions on web applications, display complex charts, manage application startup, and streamline the creation of Docker images. Gabriel Cotelli is a CS bachelor, continuous learner & free-thinker. Supporter of libre knowledge, human intelligence augmentation and open source software. Working in Smalltalk at Mercap since 2004. He's an active member of the Smalltalk development community and regular contributor to open source projects in Buenos Aires Smalltalk and Pharo. InÃ©s Sosa writes code in Smalltalk. IvÃ¡n Boaretto is a software developer by day and a computer science student by night. He is very passionate about his craft and is always striving to improve. Now, in his first time at the Smalltalks, he is looking to attract new blood to the wonderful Smalltalk community. MatÃas Fernandez is a software and tech enthusiast, and Smalltalk developer. Maximiliano Tabacman has been a part of Mercap since he started his studies in IT, which now include a PhD in Computer Sciences from the Facultad de Ciencias Exactas y Naturales (UBA). His main interest is the design of systems that apply nature inspired concepts, such as evolutionary algorithms and neural networks. Smalltalk, with its object-message design, is his natural choice for a development platform. He is also the creator of ERA, a standalone web server application for running table-top roleplaying games, which runs on Windows, Mac and Linux. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/292128721/ ) to receive the meeting details.

searching for pharo code on disk
by Siemen Baader March 21, 2023

March 21, 2023

Hi, I'm looking for some code I wrote maybe 7 years ago. A web scraper that collected data from a specific web shop. It must be somewhere in my home dir in an image, perhaps Pharo 4.0, or in .mcz files stored by Monticello. What would be a good way to search for it? I tried `grep -r --include \*.changes "server-url.com" ~` (I also asked ChatGPT as per the previous discussion on this list, and it tries its best to teach me about grep and sound very convincing while providing me with arguments that grep can't evaluate :)) with no luck so far. Any ideas? Thanks, Siemen
