Clean up method like #exiting from VAST
by Vince Refiti March 13, 2020

March 13, 2020

Hello In VAST there is a class-side method #exiting which can be implemented in an application and is called just before the image is shut down. I use it to typically implement clean-up code. Is there something similar in Pharo? If I use aBlock ensure: cleanUpBlock, is the cleanUpBlock guaranteed to run in what circumstances? Vince

Re: [Pharo-users] Generate class hierarchy from JSON Schema

Todd, this is great, I didn't know that you are working on ActiveRecord. BTW, I have some minor additions to SQLServerPlatform (support for National Language Character Set) and OraclePlatform (Decimal data type) - is there a central git repository for Glorp so that I could PR to? Thanks and best wishes, Tomaz -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

How to get a list of package versions?
by HernÃ¡n Morales Durand March 12, 2020

March 12, 2020

Hi there, I would like to compare two Pharo deployed images. Specifically, get a list/tree of the installed packages with their version number each one, so I can compare if there were updates between both deployments. I started by doing IceRepository registry collect: #workingCopy Then discovered the #commitish, though don't know is there another way? Cheers, HernÃ¡n

Hi. Are there any recent update with PharoLauncher ? It worked fine yesterday, but today I cannot launch default 8.0 image. It fail with a debug message: Instance of ZnBufferedWriteStream did not understand #name. I'm surprised to receive such message, and can't find out what has change to get suddenly such behaviour. Pharo Launcher is the latest version: Pharo 1.9.2-2019.08.01 - This distribution was built August 01, 2019. I'm using default Pharo 8.0 VM and Image, all refreshed to their latest version. However, the launcher is working well with default Pharo 9.0 VM and Image. Here is an extract of the log (full log attached) Instance of ZnBufferedWriteStream did not understand #name 11 March 2020 10:51:09.200161 am VM: Win32 - IX86 - 10.0 - CoInterpreter VMMaker.oscog-eem.2504 uuid: a00b0fad-c04c-47a6-8a11-5dbff110ac11 JanÂ 5 2019 StackToRegisterMappingCogit VMMaker.oscog-eem.2504 uuid: a00b0fad-c04c-47a6-8a11-5dbff110ac11 JanÂ 5 2019 VM: 201901051900 https://github.com/OpenSmalltalk/opensmalltalk-vm.git Date: Sat Jan 5 20:00:11 2019 CommitHash: 7a3c6b6 Plugins: 201901051900 https://github.com/OpenSmalltalk/opensmalltalk-vm.git Image: Pharo7.0.3 [Build information: Pharo-7.0.3+build.158.sha.0903ade8a6c96633f07e0a7f1baa9a5d48cfdf55 (32 Bit)] ZnBufferedWriteStream(Object)>>doesNotUnderstand: #name Receiver: a ZnBufferedWriteStream Arguments and temporary variables: aMessage: name exception: MessageNotUnderstood: ZnBufferedWriteStream>>name resumeValue: nil Receiver's instance variables: stream: BinaryFileStream: 'C:\Users\villemre\devzone\Pharo\images\Pharo 8.0 - 6...etc... buffer: nil position: 0 Any advice ?
