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...

Backing up data
by sergio ruiz Feb. 19, 2024

Feb. 19, 2024

I have been in the relational database world for decades. One of the things that is super simple is backing up and restoring data. Sometimes, it makes it makes sense to pull the production data into development. In the case of a catastrophe, itâs super simple to restore data from a backup. I am thinking of backup strategies for my data once again, and am wondering if things have changed since I was last using smalltalk. I am thinking of the following: STON I could dump all of my data into STON, but there is one slight twist. In this project, itâs just making a list of movie listings. There are three basic classes: Theater, Movie, Event. Each of these classes stores an OrderedCollection of items of that type on a class variable, as Iâll need to access each on their own.. so, if an event has a theater, Iâll need to access Theaters on their own, and Movies on their own. So, I would have to rebuild the list of Theaters from the Theaters in each event. Otherwise, I would lose the link between the Theaters on the Theater class variable and the Theater in the Event instance. Am I thinking about this incorrectly? Gemstones I am totally into the idea of using gemstones. Is there a backup and restore for objects here? do the relationships remain? Voyage This seems like a good solution, but I would rather stay in the smalltalk object store. Ideas?

UKSTUG Meeting - Pierre Misse-Chanabier: Polyphemus Take 2 - 31 January 2024
by Giovanni Corriga Jan. 26, 2024

Jan. 26, 2024

Pierre Misse-Chanabier will talk to us about Polyphemus ( https://github.com/hogoww/Polyphemus ) for the Pharo Virtual Machine. The presentation will focus on how to create Tooling on the Pharo Virtual Machine. (This does not require Virtual machine level knowledge). We will start by taking a look at a few existing tools. We will create one or two small tools, and see how they differ from tooling on the image side. Pierre Misse Chanabier is a recently graduated PhD with a focused interest on Virtual Machines, Code Generation, and Meta Programming. He worked on and contributed to many different levels and parts of the Pharo ecosystem. He is now working on how to leverage images for more than what they do now. He's currently working at Microdoc ( https://www.microdoc.com ) on the Graal VM. Born in south of France, he currently lives in Lille. This will be an online meeting from home. This is a repeat of last November's presentation that could not go ahead due to issues with our Zoom account. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/298169915/ ) to receive the meeting details. Donât forget to bring your laptop and drinks!

Books about Pharo
by Richard O'Keefe Jan. 24, 2024

Jan. 24, 2024

This is a new thread because it's not limited to any specific topic. If you have questions about Pharo, especially "how do I do <this> in Pharo", you can always ask in this mailing list. You can, if you like playing Russian Roulette, ask a Large Language Model "AI". But there is an amazing resource you should really trye. books.pharo.org Did you ever wonder where the manual for Pharo was? That's where. The site lists a bunch of Pharo books and booklets, all of which have free PDFs except for two of the books. In particular, you'll always want the most recent edition of "Pharo by Example" handy. These books are really useful. They are written by people know know their material thoroughly and do a good job of explaining it. If you want to make any serious use of Pharo, or even to have more happiness than headaches just playing with it, you owe it to yourself to get the free PDFs What do we owe the authors? Well, if you're not trying to make one pension support four people, you owe them the purchase of some of the books. Me, I'm giving them thanks, praise, and a heartfelt recommendation. Seriously, these books represent a HUGE amount of work and "you are a fool to yourself and a burden to others" if you don't take advantage of this great resource.

by Davide Varvello Jan. 24, 2024

Jan. 24, 2024

Hi Guys,I'm on a mac apple silicon with Pharo 10, I've a couple of problems First: it is not possible anymore to drag and drop the image file on the VM (pharo.app), it was very comfortable. Second: If I open the pharo.app and choose an image that becomes the only running image, I can't launch the pharo.app to run another image in parallel Are these 2 issues solvable, please? Any hint? TIA Davide

Iterating over a Dictionary
by sergio ruiz Jan. 24, 2024

Jan. 24, 2024

I need to iterate over a dictionary. I asked the AI buddy for a little help, and he says: | myDictionary | "Create a dictionary" myDictionary := Dictionary new. myDictionary at: 'one' put: 1. myDictionary at: 'two' put: 2. myDictionary at: 'three' put: 3. "Iterate over the dictionary" myDictionary do: [ :key :value | Transcript show: key , ' -> ', value printString ; nl. ]. but when i try this, I get: ArgumentsCountMismatch: This block accepts 2 arguments, but was called with 1 argument. Is the AI using a different dialect of smalltalk? how would I go about acting on each pair? Thanks! ---- peace, sergio photographer, journalist, visionary Public Key: https://pgp.key-server.io/pks/lookup?op=get&search=0x69B08F58923AB3A2 #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV @sergio_101@mastodon.social https://sergio101.com http://www.codeandmusic.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101
