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

Creating tiny Pharo images
by erik.stel＠gmail.com Jan. 15, 2023

Jan. 15, 2023

Hi all.\ \ I have created a bootstrap helper package to create tiny Pharo images. I use this for CodeParadise, but it can also be used to create tiny images which run outside the browser. It can create both 32 and 64 bit images. A tiny image is around 200 to 300Kb.\ \ Two example usages are present. See the README in the repo.\ \ [https://github.com/ErikOnBike/TinyBootstrap](https://github.com/ErikOnBike/… "https://github.com/ErikOnBike/TinyBootstrap")\ \ Happy 2023 and happy Smalltalking!

MIDI Interface?
by Stewart MacLean Jan. 13, 2023

Jan. 13, 2023

Hi all, Just wondering what the current state of interfaces to MIDI within Pharo are? I gather that there was one (SoundScores that used primitives), but that seems to have disappeared... Cheers, Stewart

CodeParadise runs on P10
by erik.stel＠gmail.com Jan. 3, 2023

Jan. 3, 2023

Hi all. A small holiday present for anyone interested: [https://github.com/ErikOnBike/CodeParadise](https://github.com/ErikOnBike/C… "https://github.com/ErikOnBike/CodeParadise") now runs on P10 (and P11 with some care)! If you are using it on P8, please unload the CP-ClientEnvironment and reload it using the "pharo8" branch: ``` Metacello new repository: 'github://ErikOnBike/CP-ClientEnvironment:pharo8'; baseline: 'CodeParadise'; load. ``` P11 seems to have some issues sometimes with restarting the image. Have not found the exact cause. Will look into this.\ \ Happy holidays!

[ANN] PI version 0.7
by HernÃ¡n Morales Durand Jan. 3, 2023

Jan. 3, 2023

Hello "PI", which stands for "Pharo Install", is a command line interface (CLI) to query and install Pharo packages: https://github.com/hernanmd/pi. With PI you can install Pharo packages in a unix-like shell command line interface. For example: $ pi install ISO3166 To get your repository listed with the "pi list" command, just tag your GitHub repository with "pharo". If there are multiple repositories with the same name, you can disambiguate specifying the repository owner: $ pi install user-name/repository-name Please let me know if this tool is also useful to you; and do not hesitate to ask a question that might appear using pi. Enjoy, HernÃ¡n

UK Smalltalk User Group meeting - 28 December 2022
by Giovanni Corriga Dec. 19, 2022

Dec. 19, 2022

For the UKSTUG 2023 holiday meeting, Simberon's David Buck will present Beagle Smalltalk. Over the past 8 years, David has been developing a Smalltalk virtual machine. He used it to release two Smalltalk Games written in VisualWorks to run on Andriod and iPhone devices. More recently, he's re-written the VM to use its own bytecode set and written his own Smalltalk compiler to make it a stand-alone Smalltalk environment called Beagle Smalltalk named after the ship that took Darwin on his voyage of discovery. David plans to release this as an open-source Smalltalk to help and encourage kids to explore the world of programming. In this talk, David presents the current status of the project and where he hopes to go with it. David Buck is the president of Simberon ( http://simberon.com/ ) - a company that has been providing Smalltalk training and consulting for over 25 years. Along with James Robertson, David produced the Industry Misinterpretations podcast and later the Smalltalk Reflections podcast with Craig Latta. David remains a Smalltalk enthusiast and works to spread the word about Smalltalk. 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/290409453/ ) to receive the meeting details.
