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

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

Rounding in Floats
by Esteban Maringolo June 17, 2021

June 17, 2021

Hi, Continuing with my issues with decimals, I'm having one issue that is not clear to me why it happens. If I do: (9.1 + (-2.0)) roundTo: 0.1. "7.1000000000000005" I expect to get a single decimal Float (rounded with whatever precision, but a single decimal). Even if I do something like this: 7.1 roundTo: 0.1 It gives the wrong result. In VW and VAST it provides the right result. (9.1 + (-2.0)) roundTo: 0.1 "7.1" In Dolphin it also returns the wrong result, it seems to use the same algorithm to round it. Is this a bug? Esteban A.

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

Standalone html builder (a la seaside without seaside?)
by Tim Mackinnon Oct. 13, 2020

Oct. 13, 2020

Hi - has anyone ever managed to extract the html builder out of seaside - or written something equivalent? I often find I want to build some HTML, but donât want the full seaside - and was wondering if anyone has managed to extract it, or have something similar? This combined with Renoir from BA-ST would give a good little light weight web potential to run with Zinc. Tim
