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? 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

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.

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

Git Repositories browser vs. monticello
by sergio ruiz Jan. 19, 2024

Jan. 19, 2024

In the workspace, I see that Git Repositories browser if the first selection, and Monicello is marked as legacy. The last time I was using Pharo, I think the Git browser was called âIceberg.â Are these the same thing? Have we now made the move to Git as our primary SCM?

Pharo on Raspberry Pi in 2024
by Rob van Lopik Jan. 19, 2024

Jan. 19, 2024

With the new Raspberry Pi 5 (8Gb) I finally got hold of, and the new Raspberry OS (Bookworm 12), I thought it was time to try Pharo again (see Pharo issue #11841 by @astares). I used zero-config with version specification, like 'get.pharo.org/100+vm'. (On pharo.org there are no OBS packages for Bookworm). Using Raspberry Imager I put 64-bits Bookworm on the Pi5. The installs for Pharo 9, 10 and 11 worked OK. Pharo12 does not work because files.pharo.org/get-files/120 does not contain an aarch64-vm. The P12 image does work with the VM downloaded for P11. UI performance is excellent. Next I tried 32-bits Bookworm (Raspberry OS 12) on the Pi5. As there are no recent 32-bits Pharo images (issue #12769) I only tried P9 and P10. Directly using zero-config loads 64-bit Pharo and even explicitly specifying 32-bit (through 'get.pharo.org/32/90+vm') results in a 64-bit download. The reason is, that the Pi loads a 64-bit kernel even when the OS itself is 32-bits. This means the command 'uname -m' that is used by zero-config, returns 'aarch64' instead of 'armv7l'. I will report this on the zero config repo. So I downloaded and unzipped manually.. Pharo 9 works fine. The Pharo 10 image misses Playground in the menu, but ctrl+O+W works. On a Pi 4 (8Gb RAM) with 64-bits Bookworm Pharo 10 is OK. Pharo 11 (with VM 10.0.5 2023-05-05) gives an error: '[ERROR] 2024-01-16 21:37:55.000 sqAllocateMemory (src/memoryUnix.c:160):I cannot find a good memory address starting from: 0x10000000000'. With 32-bits Bookworms it behaves the same as the Pi (i.e. it also loads a 64 bits kernel) Next I tried the same on a Raspberry Pi 3B+ (1Gb memory). For 64-bits the Raspberry Imager default to the Bullseye version (11) . Pharo 10 and 11 complain about a wrong libc.so version and don't work. Using Bookworm ( 64-bit) Pharo 10 runs OK . Pharo 11 does not work, with the same error as on the Pi4 Last I tried the Raspberry Pi Zero 2W (512 Mb RAM, but only â¬20!). First 32-bits Bookworm. Pharo9 works. Pharo10 also with the incomplete latest image. 64-bits Bookworm seems a bit heavy for this board, but it works. Pharo10 runs, more or less. Maybe headless would be quite useful. Pharo11 gives the same memory allocation error as on the Pi 4 and 3B+ Summary: - On the Pi 5 all Pharo 64 bits versions work - On other Pi's only version 9 and 10 work. Pharo11 has a memory allocation error. - Recent 32-bits Pharo images are lacking; especially for the cheap Pi Zero I would really like to see whether 32-bits is more usable.

Troubleshooting ByteArray
by sergio ruiz Jan. 18, 2024

Jan. 18, 2024

Hi, all. I am working on creating a PDF with Artefact (https://github.com/pharo-contributions/Artefact) and am having an issue running the first example. the Example looks like: PDFDocument new add: (PDFPage new add: (PDFTextElement new text: 'Hello'; from: 10mm@10mm)); exportTo: 'test.pdf' asFileReference writeStream. When running this, I get the error: Instance of ByteArray did not understand #isByteString indeed, ByteArray does not have a method called isByteString. I have tried creating a method that returns either true or false (I tried them both), but I have not successfully built the PDF. The method calling isByteString looks like: ZnUTF8Encoder next: count putAll: string startingAt: offset toStream: stream "Write count characters from string starting at offset to stream." "Overwritten for performance reasons - create a fast path for byte strings" string isByteString ifTrue: [ self next: count putAllByteString: string startingAt: offset toStream: stream ] ifFalse: [ super next: count putAll: string startingAt: offset toStream: stream ] I TOTALLY get this. This is a whole bunch of very specific questions. But my ultimate goal is to take a deep dive into stream processing to figure this out.

GLASS Platform - Docker container?

Jan. 17, 2024

Hi, all. I used the GLASS platform years ago, and I was thinking it might be a good match for my upcoming projects. The documentation looks to be the same documentation I used back when I started with Seaside. I am wondering if GLASS has been ported to Docker yet. This seems like a natural extension.

Document layout with Pharo
by Sergio Ruiz Jan. 15, 2024

Jan. 15, 2024

Hi, all. I am looking to create a newspaper like listing of movie showtimes. Initially, I thought of using imagemagickâs annotate command to generate the output. Thinking further, I thought it might be worthwhile to generate a LaTeX file, and render that to a jpg. Then, I thought there might be a better way to do this natively in smalltalk. Does anyone have any idea how I might generate a document that can be converted to an image with a reasonable amount of control of the layout? Thanks!

Updating objects in the inspector
by sergio ruiz Jan. 15, 2024

Jan. 15, 2024

Hi, all. I have been away from Pharo/Smalltalk for several years, but I am coming back to it now. I am a senior developer, but havenât used smalltalk in any professional projects. I also found that I donât do ANY pet projects for fun anymore, as the current batch of languages/frameworks are not fun. They are effective and all. But not fun. I am starting a bunch of âscratch my own itchâ projects. Iâll be using Pharo as the data store, and maybe more. The thing I really want to do is document the usage of Pharo in my projects, and explain the toolchain, and why i chose each piece. My first project is to take a list of movie events from the local theater and create a listing reminiscent of the newspaper listings we read in the olden days. I have my models set up and figured out, but I have a really simple question. How do i change the value of an instance variable in the inspector. It looks like it should be super simple, but itâs not working. In this case, I am just trying to take the period out of a string. See that attached image. Thanks, all! ï¿¼ ---- 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

Jan. 14, 2024

I am trying to remove some objects from an OrderedCollection in the inspector. I have class called Event. This has a class variable called Events which is a storage are for and ordered collection of Events. So, i inspected âEvent Eventsâ and I see my ordered collection. In the inspector, I select on of the objects, and I try to evaluate âEvent Events remove: selfâ.. But I am getting an error: an Event not found in OrderedCollection. Does anyone have any ideas on how iâd do this? Thanks! ï¿¼ ---- 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

How to halt on Test errors?
by Davide Varvello Jan. 9, 2024

Jan. 9, 2024

Hi Guys, Sometimes I'd like to stop my test suite when an error occurs. My raw approach is to put a self halt in the TestResult>>addError:Â and look at the debugger, but I'm wondering if there is a more suitable way. Can you help me, please? TIADavide
