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

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

mapping CamelCase to <custom-tag-name>
by Siemen Baader Nov. 6, 2022

Nov. 6, 2022

Hi, I'm looking for an elegant way to convert class names with optional namespace prefixes to names for custom html elements. MYCustomElement and CustomElement to <my-custom-element> and <custom-element> There must be an elegant way to do it with regex or inject, but I'm embarrassed to say I can't get my head around it. I can get it to match the regex '((:isUppercase:+)*)((:isUppercase::isLowercase:+)*)', (if I recall correctly) but can't get a collection of the individual elements 'MY' 'Custom" 'Element' to lowercase and join. Thanks for any hints! cheers Siemen

Recovering old images in mac
by Arturo Zambrano Oct. 30, 2022

Oct. 30, 2022

Hi Everyone, I have some old images (around 2017) that I would like to load. Pharo Launcher downloaded a VM but while trying to launch it complains with the following message. Error: Error: posix_spawn(), code: 86, description: Bad CPU type in executable Which is the same message I get when trying to use the VM I found in a backup of that time. Is there a way of opening such an old image in MacOs Monterrey (running on top of the same machine this image was originally built)? If I am not mistaken it is Pharo 6. Best regards Arturo -- Arturo Zambrano LinkedIn: https://www.linkedin.com/in/arturozambrano/

How to handle conflict resolution in baselines?
by Eric Merritt Oct. 27, 2022

Oct. 27, 2022

Everyone, In a baseline in a project I am working on I have a dependency on both Magritte and Seaside. Magritte loads fine, but when Seaside loads, Monticello declares a conflict on the Grease package. You can see the WIP baseline here: https://github.com/ericbmerritt/profeos/tree/feat/working-goals/BaselineOfP… . So far, I haven't found a solution to resolve conflicts in the spec. The closest solution I have found is here: https://github.com/CCMi-FIT/kendrick-modeller/blob/9c76ff8170c67d5472cc1e1b… It works but seems to be stepping out of the declarative form of baseline definition. Is there another solution? Thanks, Eric

Looking for a freelance developer
by Johan Brichau Oct. 21, 2022

Oct. 21, 2022

Hi Pharoers, At Inceptive, we are looking for a freelance software developer to help us improve our cloud ERP software âOrderflowâ (www.orderflow.be <http://www.orderflow.be/>). Orderflow is developed in Pharo and deployed in GemStone, using Seaside and jQuery/Javascript. Launched already more than 10 years ago, Orderflow grew steadily and we have now reached a point where we need to strengthen the team to sustain further growth. You willl be joining a small team, where communication is direct and to the point and where your skills and efforts will be highly visible. So there will be no red tape ;-). Changes have to be pushed in small chunks and incrementally. Iâm sure youâll feel the hart beat of a thriving product. Orderflow is a highly graphical and customizable document-based workflow system that assists clients in managing supplies, purchases, sales, projects, budgets. Although it is generally applicable for many kinds of businesses, we are mainly active in the educational sector. Large technical schools and catering/hotel schools are relying on the software to manage their flow of goods. It is a collaborative tool where a lot of people interact with ranging from parents and students all the way to the school board. Over the last decade Orderflow has grown to become an important player in the Belgian educational market. There are over 60 schools that use Orderflow on a daily basis. Disclaimer: Orderflow is not connected to Yesplan, where you might know me from. It is developed using the same wonderful technologies but is a smaller and separate project primarily operated by my colleague Thomas. Please send any inquiries or reactions to me at johan(a)inceptive.be <mailto:johan@inceptive.be> Cheers Johan

Sponsoring our new mooc
by stephane ducasse Oct. 5, 2022

Oct. 5, 2022

Since more than a year we have been working on a new mooc called: âAdvanced Object-oriented Design and Developmentâ It will be quite good. We are bullet proofing it with a new lecture here at Lille. It will not focus on Pharo but on object-oriented design, tests, design patterns. It will present - Test and test-driven - Essential aspects of OOP - Basic and universal principles - Double dispatch - Case studies in Pharo - Some design patterns - Some coding idioms and we will composed of 8 modules Currently it has around 50 lectures and we expect around 60 + exercises. You can access some drafts of the support here: https://rmod-files.lille.inria.fr/?dir=DesignCoffeeClub <https://rmod-files.lille.inria.fr/?dir=DesignCoffeeClub> The production cost of this mooc is around 200 K Euros financed by Inria and it will be filmed in January. We hope to deploy it in April or May 2023. The mooc will be produced in english (and may be dub in french). It occurred to me in this difficult time to find good developers that some of you may want to sponsor this mooc\to get exposure. You can be associated with some of the best OO teachers: me, Guillermo Polito and Pablo Tesone. We have cumulated more than 40 years of teaching experience. Several books... Yes at the end of the day we should sale a bit our expertise - check below our track record with the previous mooc. As a sponsor you will get your logo and links on all the supports: Slides and videos. Note that this mooc is designated to have a live time of 10 years or more. It is teaching fundamental points of OOP. So this is a unique opportunity to market your company to people wanted to learn advanced OOP Note that there are no other lectures like this one. We have two levels of sponsoring: 2000 Euros for platinum sponsor 1000 Euros for plain sponsor Let us know. Just a little reminder of the previous Mooc on Pharo. It has more than 8 years. For the record, some youtube videos (that we published after 4 years of running the pharo mooc) got more than 6000 views and this is by developers. We got around 10000 followers not counting the people watching the mooc on youtube and here are some of the testimonies we collected over the years. J'ai trouvÃ© Ã§a trÃ¨s intÃ©ressant, beaucoup plus que prÃ©vu ! je regrette de ne pas m'y Ãªtre mis plus tÃ´t. J'ai enfin l'impression de vraiment faire de la POO ! Ou Ã l'inverse je me rend que je n'en faisais pas vraiment... - Anonymous, 2019 I have just completed week seven of the Pharo Mooc (beginner and object oriented tracks) I am starting a redo of the Mooc with the web track (TinyBlog project). I have already learned so much ! I have spent the last 20 years or so in software development and, following this Mooc, I realized I hadnât really grasped the essence of object oriented design. - Anonymous Â« Really one of the best mooc I have ever attended. And I have attended quite a few (openSAP, openHPI). As an old fashioned ABAP developer I want to be reborn as Pharo developer in my next life :-) Â» - Anonymous Hi! I finished the MOOC some weeks ago and I would like to congratulate everybody involved! After a decade+ of Python programming I think I found my new favorite language :). I'm making a small Teapot server for Slack command bots, I'm goona push it to Github (yay Iceberg), if anyone is interested. - EduardoPadoan I just completed the @pharoproject Mooc the best investment I have ever made of my time. MAQBOOL Hey all - I've just finished the Mooc - thanks for an excellent course and a thouroughly interesting look at a new way to program :smile: Looking forward to starting to play with Pharo on some upcoming ideas I've had. - Tieryn As much as I thought I understand object-orientation, it is very clear NOW that without a truly useable Smalltalk, which Pharo is, it is impossible to really understand and exercise object-orientation. Thank you all soooo much. - Mike D. 06/12/2020 I finished the Pharo MOOC a few days ago. Thank you very much to Damien, Stephane, and Luc for their work on the material! I enjoyed it very much - Anonymous Hey all - I've just finished the Mooc - thanks for an excellent course and a thouroughly interesting look at a new way to program :smile: Looking forward to starting to play with Pharo on some upcoming ideas I've had ð3 - Anonymous I already had previous Smalltalk experience, but yes, I'm extremely happy Chapter 7 has been extremely fulfilling - Anonymous A general comment I wanted to make is that the MOOC so far has been great. Impressed with the quality and content, and grateful that it is available and free. Many thanks! - Aryeh IMHO the videos were very well done. I would even say shockingly well doneâ¦ for a bunch of programmers who are supposed to be clueless about design - SeanDeNigris - 10/26/2017 The more I learning about @pharoproject the more I appreciate it's beauty and simplicity, finally, object-oriented programming is done right - MAQBOOL Mooc absolument remarquable. Superbe voyage autour de Pharo. Le paradigme objet qui (re)prend enfin du sens ! - Anonymous - 01/03/2019
