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

TelePharo status
by Gerry Weaver July 29, 2024

July 29, 2024

Hello All, Are there any plans to get TelePharo working again? I've been checking when each new version is released, but no luck so far. I haven't tried version 12, because I assume it is not working. I'm thinking about a project where it would be pretty cool to have TelePharo. Unfortunately, I lack the exprerience with Pharo to attempt to fix it myself. -- Thanks, Gerry

This week (30/2024) on the Pharo Issue Tracker
by Marcus Denker July 26, 2024

July 26, 2024

The most important not obvious news of the week: We managed to get the CI in a good shape again! Test are now green for all three platforms. This is one of these aspects of development that are easily overlooked: Just keeping the CI green and running is far more work in a real project than you would naively think. Summer break: the weekly mails (but not the improvements to Pharo!) will take a break. In the week of 26/08 we post the weeksly logs for weeka 31-34. # Pharo 12 Backports - Automatically type 'NULL' arguments in FFI (backport to P12) #16926 https://github.com/pharo-project/pharo/pull/16926 - [Backport] Update FormSet to not recompute each scalling all the time #16887 https://github.com/pharo-project/pharo/pull/16887 # Fixes - Fix bug in protocol management of Traits #16936 https://github.com/pharo-project/pharo/pull/16936 - Instance of NullWorldRenderer did not understand #fullscreenMode: when run headless / in CI #16925 https://github.com/pharo-project/pharo/pull/16925 - Catch CmCommandAborted in Calypso #16920 https://github.com/pharo-project/pharo/pull/16920 - Fixes icon for packages drop list in StRequestClassPresenter #16856 https://github.com/pharo-project/pharo/pull/16856 - Handles permission problems on FileBrowser #813 https://github.com/pharo-spec/NewTools/pull/813 - Use equality to compare file references in file navigation system #811 https://github.com/pharo-spec/NewTools/pull/811 # Improvements - Enable specification of a comparison strategy to compare list items #1573 https://github.com/pharo-spec/Spec/pull/1573 - Improve IconStyler highlight to be base on theme #16943 https://github.com/pharo-project/pharo/pull/16943 - Add isPackage #16935 https://github.com/pharo-project/pharo/pull/16935 # Rules - improve ReCollectionProtocolRule #16918 https://github.com/pharo-project/pharo/pull/16918 - Deprecated package #16931 https://github.com/pharo-project/pharo/pull/16931 - change rules description UI #16929 https://github.com/pharo-project/pharo/pull/16929 # Cleanup - ListView-Tests should depends on Tests #1576 https://github.com/pharo-spec/Spec/pull/1576 - ListView adapters should be close to morphic adapters #1575 https://github.com/pharo-spec/Spec/pull/1575 - Fix dependency test #806 https://github.com/pharo-spec/NewTools/pull/806 - Remove MCMergeBrowser #16950 https://github.com/pharo-project/pharo/pull/16950 - Monticello: remove dead code and some Morphic UI #16949 https://github.com/pharo-project/pharo/pull/16949 - Move UndefinedClassVariable out of the Kernel #16947 https://github.com/pharo-project/pharo/pull/16947 - Remove useless method: CompiledMethod >> argumentNames #16937 https://github.com/pharo-project/pharo/pull/16937

MethodProxies
by Sebastian Jordan Montano July 16, 2024

July 16, 2024

Hello, As presented at ESUG, we have released the new version of MethodProxies for Pharo 12 and 13. MethodProxies is a library that allows to control message-passing to instrument any method in the system to execute an action before and after a method's execution. We worked a lot on this new version to optimize it to have a low overhead. We have also a release for Pharo11 and less but that version does not have our optimizations, but you can use it without any problem. If you really need Pharo 11 and want to use the new fast and optimized version, you can contact me. You can find it here: [ https://github.com/pharo-contributions/MethodProxies | https://github.com/pharo-contributions/MethodProxies ] Cheers, Sebastian Jordan

Looking for new adventures
by Koen De Hondt July 12, 2024

July 12, 2024

Dear Pharo Community, As you may have read on my blog <https://all-objects-all-the-time.st/#/blog/posts/1> or heard during my ESUGâ23 presentation, eighteen months ago I entered the Pharo scene after being away from the Smalltalk community for 20 years. For the last one and a half years, I have been a member of a team using Pharo and GemStone. I attended almost all Pharo Sprints in Lille (every last Friday of the month). In this channel, I have informed you about my intention to build a new browser based on Spec. That development has been on the back burner for the last five months because I have been working hard with StÃ©phane Ducasse to finish the book âApplication Building with Spec 2.0â. I have presented at ESUGâ23, and I am sad that I could not attend ESUGâ24 this week. >From the above, my contribution to the Pharo community is clear, and I think my drive to contribute more is also clear. In a few months, I will leave the team I am working with now. Therefore, I am looking for new adventures. If you are looking for a seasoned software developer who likes working in Smalltalk/Pharo very much, please send me a message, and I will be in touch rapidly. Please find more details on my career history on LinkedIn <https://www.linkedin.com/in/koendehondt/>. Best regards, Koen

Help with PetitParser2 rules
by Rafael Luque July 7, 2024

July 7, 2024

Hi all, I'm struggling with a small parser using PetitParser2. Here is a fragment of some of the rules I'm defining but their behaviour is not as I could expect: andKeyword := 'and' asPParser trim, #letter asPParser not. notKeyword := 'not' asPParser trim, #letter asPParser not. keyword := andKeyword / notKeyword. nonKeywordIdentifier := keyword not, #letter asPParser, #word asPParser star. word := nonKeywordIdentifier, #blank asPParser star. words := word star. The behaviour of the "nonKeywordIdentifier" is the expected: identifier end parse: 'hello'. "It parses successfully" identifier end parse: 'and'. "It fails as 'and' is a keyword" However the "words" rule's behavior is the following: words end parse: 'hello Pharo'. "It parses successfully" words end parse: 'hello and bye'. "It parses, when I would expect it fails because of 'and' is a keyword" I don't understand why the "words" rule works this way, but I'm starting with PetitParser. Any suggestions? Thank you.
