[SOLVED] Shortcut CMD-v for version history
by Davide Varvello May 26, 2024

May 26, 2024

Hi, If you too miss some shortcuts like... cmd-v to show the versions of a method, here is the solution, you have to add methodShortcutActivation to SycShowMethodVersionCommand class: SycShowMethodVersionCommand class >> methodShortcutActivation <classAnnotation> ^ CmdShortcutActivation by: $v meta for: ClyMethod asCalypsoItemContext HTH Cheers Davide

3D graphics?
by Kasper Osterbye May 24, 2024

May 24, 2024

Cheers all I am looking for classes which can be used to build 3D pictures. Spheres, Boxes, etc. It is a fun thing for me to build, but on the other hand, if it is already done, I will use them. Also, I am interested in 3D figures being outputtet in STL files. Is that done? It is an easier thing for me to build (have done some work already). I want the stl format as I can pass that on to 3D printers. Are there anyone else who have worked from Pharo to 3D printing (prusa for example). Best, Kasper

DATE CORRECTION - UKSTUG Meeting - Javier Pimas -- Live Metacircular Runtimes: The case of Egg Smalltalk - 29 May 2024
by UK Smalltalk May 22, 2024

May 22, 2024

Egg is a new Smalltalk dialect that was designed from scratch to incorporate some interesting features: A module system with namespaces that replaces the old-good Smalltalk global. Dynamic identifiers, which are bound lazily similarly to how methods are lazily bound. A multi-VM architecture, with different VM implementations written in C++, Pharo, JavaScript and Egg. The Egg-in-Egg VM is special in that the VM component is just another module of the system, creating what we have named Live Metacircular Runtimes (LMRs) [1]. The most interesting characteristic of LMRs in Smalltalk is that they can be developed using standard Smalltalk tools, which shorten feedback loops when doing VM development. During the talk I'll show a little bit about Egg and its LMR, and how not only VM developers get more productive when writing VMs, but also application developers can better understand what the VM does behind the scenes. [1] https://arxiv.org/abs/2312.16973 - Live Objects All The Way Down: Removing the Barriers between Applications and Virtual Machines Javier Pimas is a fan of high-level low-level programming. He has been successfully mixing Smalltalk and assembly code for more than a decade. Within Bee Smalltalk, SqueakNOS and now Egg Smalltalk projects he has been trying to make live-programming of system-level concerns more practical to application programmers. Javier works for Labware and Quorum Software, where he applies his expertise to real-world challenges while pursuing a PhD in Computer Science at Buenos Aires University. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's Meetup page ( https://www.meetup.com/ukstug/events/300511322/ ) to receive the meeting details.

https://github.com/orgs/pharo-project/projects/8 lists some easy projects. I'd like to make a contribution. Where are the instructions on how to sign up and what to do? Fair warning, I'll probably need a bit of hand-holding...

P12 new Tonel formatting and PR implications
by Tim Mackinnon May 15, 2024

May 15, 2024

Asking this here as it didnât get much traction on Discord - but with the move to P12, the category format in Tonel has changed from a symbol to a string e.g. { #category : #examples } vs { #category : 'examples' } - this causes mega noise when submitting tiny PR's - how is everyone else handling this? Should projects resave every project module to get the new format while people are out of the pool? Or is there a way to force the old format on specific projects until they can be upgraded ? It seems like a change whose consequences need some attention ? What are others doing? Tim
