Re: [Pharo-users] CodeCity like visualization in Linux

by Rafael Luque

Thank you for your help Tudor. I'm trying with the CodeCity image I've downloaded from your post ( http://www.humane-assessment.com/blog/communicating-changes-in-pharo-3-0) and I get the error "MessageNotUnderstood: receiver of "platformId" is nil" in the NBMacGLContextDriver class>>supportsCurrentPlatform method. By this reason I thought it only works on Mac or maybe I must previously configure something to get the NativeBoost working on Linux.

Re: [Pharo-users] Dynamically changing code in a safe way

Once the value was sent to the block, the block started executing and is no longer under the control of the HotSwapping object. Another way of looking at this is to ask yourself what is the granularity of the think that you are changing. In your original example, you made a new assignment to currentBlock, but the code (operating on the old value of currentBlock) does not re-read this variable each time aroind the loop. It reads it just once, before it starts looping. So changing it afterwards wonât matter. In contrast, suppose that you were to recompile a new version of Trasncript>>#show: while your loop is running. The version that is currently executing would finish, but the next time that #show: is sent to Transcript, you would execute the new version.

Re: [Pharo-users] Glorp: #includesKey:

by jtuchel＠objektfabrik.de

Herby, I must admit I've never used Dictionary Mappings with Glorp, so I don't have an answer. But I am a bit confused by your code examples.

Is #tools really a Dictionary? Inside the Block, I'd expect the :tool parameter to be an Association, and that doesn't understand #id,does it? I guess @each is the parameter within an Block like in self session read: MyClass where: [:each| each tools ...] If so, I have a hard time believing that anySatisfy: would work (never tried)... > > > Is it the bug / feature / problem in my approach?

My first tip would be to try and find some slides (most likely made by Niall and presented at an ESUG) including the words "subquery", "glorp" and "exists". You won't find much, but that may be a starting point.

CodeCity like visualization in Linux

by Rafael Luque

Hi all, I'm working on an introductory talk about Pharo for a software craftsmanship local meetup. The presentation will be mainly driven by demos and I'd like to show a CodeCity-like visualization. I've been able to load it in Pharo 5, but it get an error when select the "City" tag in GTInspector. It seems that NBOpenGL does not work in Linux. Do you know any way to make it work in Linux? Thank you. â

Re: [Pharo-users] Can we halt on memory growth beyond a limit?

by ClÃ©ment Bera

Hi, You can start the VM with this parameter: --memory <size>[mk] use fixed heap size (added to image size) When the memory is reached you have an out of memory error. Check --help on the VM.
