EXIF / JPEG metadata

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

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

WebDav and CalDav in Pharo ?
by CÃ©drick BÃ©ler April 13, 2022

April 13, 2022

Hi all, I do some experiments with iCal. For now I serve a full calendar over HTTP. Not bad, but it is read only. Iâd like to try CalDAV. I was looking for it, and also webDAV. Gofer it smalltalkhubUser: 'UdoSchneider' project: 'FileSystemNetwork'; configuration; load. #ConfigurationOfFileSystemNetwork asClass project stableVersion load: 'Webdav' Iâve found the project of Udo, but it doesnât load on P8. I think this is due to the stream refactoring. Right now the image hung. Iâll try maybe to load it manually. But I was wondering oof there were other alternatives ? TIA, CÃ©drick

Is there any way to display the Class Hierarchy as a Diagram or a indented list. Even for all the classes in a package will do. ----- cheers, Sanjay -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

pharo 8 - method versions - how to see author/timestamp?
by PAUL DEBRUICKER Feb. 8, 2021

Feb. 8, 2021

Hi - Sometimes I want to revert to older versions of methods e.g. from an hour ago. In the "Recent versions of MyClass>>#myMethod" dialog no timestamps or authors are present. How do I see those? Thanks Paul

Hi, Does anybody know if there is an OCR or some CV library available for Pharo? I would like to make an experiment with recognizing the content of some fixed size form, and of course I prefer to do it with Smalltalk whenever possible. Regards! Esteban A. Maringolo

ported and refreshed Crypto-Nacl to GitHub (from StH)
by Jonathan van Alteren Sept. 17, 2020

Sept. 17, 2020

Hi all, I wanted to let you know that I ported the Crypto-Nacl library from SmalltalkHub to GitHub here:Â https://github.com/objectguild/Crypto-Nacl The original author is Tony Garnock-Jones, with contributions from HernÃ¡n Morales Durand. See the README for more details. Libsodium has evolved a lot over time, which means that there is plenty of additional functionality that can be unlocked through this library. I don't have a need for it at the moment, but that might change in the near future. My interest is in using the cryptographic features to enhance security of business applications. Oh, and thanks to the Buenos Aires Smalltalk team (https://github.com/ba-st/) for inspiration on using GitHub Actions with smalltalkCI :-) Cheers, Jonathan van Alteren Founding Member | Object Guild B.V.
