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

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

Books

July 30, 2022

I am learning Pharo and like to have printed copies of books. I see that âPharo 9 by Exampleâ has been released and it shows âGet printed (soon)" When will that be available on lulu to purchase? Also there is another book titled âPharo with Styleâ and there are two links to buy a printed version, but both sites are in French. Will this book be available for purchase on lulu at some point? Thanks!

First time Pharo experience: TFFIBackend induced crash...
by mylists＠posteo.de May 29, 2022

May 29, 2022

Hi, (Running GENTOO Linux 64bit/no 32bit layer) I just downloaded the Pharo Launcer and followed the instructions given here: https://pharo-project.github.io/pharo-launcher/create-images/ I choose the newest stable image and launched it. A post mortem screen pops up (see attachment). Since I just started with Pharo Smalltalk, i can only guess, that something with the âTFFIBackendâ (whatever that isâ¦ ;) ) failed and Pharo stopped working. I would like to use Pharoâ¦ How can I fix that problem? Cheers!

PDFtalk for Pharo - first fileOut
by christian.haider＠smalltalked-visuals.com May 29, 2022

May 29, 2022

Hi Pharoers, as some of you know, there is a project on the way for porting the PDFtalk library from VisualWorks to non-namespaced Smalltalks [1]. Now, the first fileOut of the full PDFtalk library, including Values and tests, is available for Pharo [2]. The fileOuts should load into Pharo 10.0 (or 9.0, 8.0, 7.0 and 6.1) without errors. The files are about 5 MB in size and take around 6 to 10 minutes to load on my machine. There are lots of load warnings in the Transcript and many tests have errors, but all code loads and can be browsed and examined. The tool automatically rewrites namespaced names with prefixed globally unique names. This seems to work well and automates away much of the usual porting work. Now I am looking for a Pharoer with an interest in PDF and/or the transformation tool and some time at hand to pair up for some coding. This is an exiting project. Heads up - who wants to be part of this? Happy hacking, Christian [1] https://wiki.pdftalk.de/doku.php?id=pdftalknonnamespacefileout [2] https://wiki.pdftalk.de/doku.php?id=portingblog#first_fileout_of_the_full_pd ftalk_for_pharo P.S. I hope that I am writing to the right list - apologies, if this is spam for you

Bonjour Service Discovery App available, and FFI library interface help required!
by Stewart MacLean May 25, 2022

May 25, 2022

Ok, after bashing my head against the Spinning Wheel of Death for ages trying to use FFI to interface to the Bonjour service discovery library, I've done it another way using essentially the same design framework, but scraping the command line output from dns-sd with the help of OSSubProcess. This is on a MacOS/M1/Monterey, Pharo 10 setup. This works nicely, but I would still like to get to the bottom of why the FFI doesn't work for this. So I've made all the code available on https://github.com/StewMacLean/Bonjour. You can either download a preloaded image/changes or use Metacello to download and install into a fresh P10 image. Once downloaded, it will select the openApp for the command line interface to run. To run the library interface you need to do the same thing, in that class - please refer to the read me and browse the code. I'd really appreciate any help I can get to get this working. I think it would make a great demonstration app for FFI usage once running. Please sing out with any questions etc. Thanks! Stew MacLean

SmaCC: Adding conditions to production rules
by Konrad Hinsen May 24, 2022

May 24, 2022

Hi everyone, I am stuck with a problem in SmaCC (of which I am a newbie user). Hoping for suggestions from experts, any kind of pointer is welcome! I have a production rule for infix operators: Term : NonInfixTerm 'arg' (<opIdentifier> 'opName' NonInfixTerm 'arg') * {{InfixOpTerm}} | NonInfixTerm ; According to the syntax rules of my language, infix terms are valid only if all <opIdentifier>s are equal. Otherwise parentheses must be used to disambiguate, as the language has no precedence rules. How can I do this with SmaCC? I don't see how I could do it using the basic features, but maybe with some tweaking on the Pharo side. Thanks in advance, Konrad.
