Wow things have changed.

Looking at Pharo 4.0 First, I'm a little confused by the Configuration Browser - did this replace Monticello?. I'm not clear on the difference between a package and configuration and also the "Load Stable" vs "Load Configuration". Is Load Configuration the bleeding edge or something? I guess I could use a primer on the new modern way of managing code packages. I have a project to do that will involve a raspberry pi 2, a data feed from an arduino managing sensors, mapping/navigation, and a touch screen. In my googling I have spotted some articles on running Pharo on raspberry pi, and open street map with roassal2. I'm basically building an appliance here but would love to develop on my mac and deploy to the raspberry pi 2 as full screen. I looked at the release notes for raspbian OS and it seems a package 'squeak-vm' was updated in 2013 for it. Not sure about cairo for roassal2? Any pointers? I think this could be a really cool use case for Pharo. Thanks -Todd Blanchard

Flow layout for Bloc/Brick?
by Stephan Eggermont Nov. 6, 2015

Nov. 6, 2015

Is there already a layout for Bloc/Brick that lays out submorphs horizontally as long as they fit and then adds them on new lines? It is still unclear to me where Bloc/Brick questions should go. Stephan

NativeBoost: Could not find accessor for variable "aModuleName" in NativeBoost>>#loadModule:
by Nicolas Anquetil Nov. 5, 2015

Nov. 5, 2015

Anybody has an idea what the problem could be? Difficulty is that I cannot debug directly because it is not on my computer. The library to load (/usr/lib/cairo.so.2) is present on the computer and pharo detects it. Any idea on how to investigate this or where the issue could lie? nicolas

Nautilus with fasttable and transparenticons
by Nicolai Hess Nov. 5, 2015

Nov. 5, 2015

Since we use FastTable in Nautilus, if you drag a Nautilus window, some icons become transparent. (protocol icons for "private" and "initialization"). This is because fast table scales all icons to size 16@16 and this will convert 8bit forms to 16 bit forms and this may lose transparency information. you can simulate this with f:= Form extent: 100@ 100 depth:32. fill := (GradientFillStyle colors: (Color wheel: 10)) origin: 50@50 ; direction: 0@50;radial:true. f getCanvas fillRectangle: (10@10 extent: 80@80) fillStyle: fill. f getCanvas frameRectangle: f boundingBox width:2 color:Color blue. (f asFormOfDepth:16) asMorph openInHand. drawing this imagemorph works on the display screen but if you drag the morph it becomes invisble (what you see is only the shadow). the same behavior if you start with a form of depth 8. converting a form of depth 32 to 8 or 8 to 32 works. 8 to 16 or 32 to 16 does not work. There were some discussions on pharo/squeak ML (search for "fixalpha") But I don't know where this is fixed in squeak, but it works in squeak. I don't know exaclty what's the problem, converting the form or displaying it? any ideas?

[ANN] CalipeL: a benchmarking tool for Smalltalk/X and Pharo
by Jan Vrany Nov. 5, 2015

Nov. 5, 2015

Hi there, After more than 2 years of (time-to-time) development and aboutÂ that much time of use, I'd like to announce CalipeL, a tool for benchmarking and monitoring performance regressions. The basic ideas that drove the development: * Benchmarking and (especially) interpreting benchmark resultsÂ Â is always a monkey business. The tool should produce raw numbers, Â letting the user to use whichever statistics she need to make up Â (desired) results. * Benchmark results should be kept and managed at a single place so Â one can view and retrieve all past benchmark results pretty muchÂ Â the same way as one can view and retrieve past versions ofÂ Â the software from a source code management tool. Features: - simple - creating a benchmark is as simple as writing a methodÂ Â in a class - flexible - a special set-up and/or warm-up routines could be Â specified at benchmark-level as well as set of parametersÂ Â to allow fine-grained measurements under different conditions - batch runner - contains a batch runner allowing one to runÂ Â benchmarks from a command line or at CI servers such as Jenkins. - web - comes with simple web interface to gather and processÂ Â benchmark results. However, the web application would deserve Â some more work. Repository: Â https://bitbucket.org/janvrany/jv-calipel Â http://smalltalkhub.com/#!/~JanVrany/CalipeL-S (read-only export Â from the above and Pharo-specific code) More information: Â https://bitbucket.org/janvrany/jv-calipel/wiki/Home I have been using CalipeL for benchmarking and keeping track ofÂ performance of Smalltalk/X VM, STX:LIBJAVA, a PetitParser compilerÂ and other code I was working over the time. Finally, I'd like to thank to Marcel Hlopko for his work on theÂ web application and Jan Kurs for his comments. I hope some of you may find it useful. If you have any commentsÂ or questions, do not hesitate and let me know! Regards, Jan

[ANN] QuickAccess for Pharo 5
by Torsten Bergmann Nov. 5, 2015

Nov. 5, 2015

Hi, I quickly wrote yet another small tool to work faster with Pharo. I call it "QuickAccess" - it's some kind of "ScriptManager 2.0" allowing you to quickly access actions (defined as code scripts) via Spotter, Menu, Button, etc. You can load it from Spotter/Catalog in Pharo 5.0 beta. The following video demonstrates how to use it: http://youtu.be/j-dTp6i_P3s The defined structure including the scripts can be exported to a file and send around. So far it is "complete" for my own requirements - if you feel something is missing you can contribute and help moving it forward. The repo is at http://www.smalltalkhub.com/#!/~TorstenBergmann/QuickAccess Contact me with your STHub account if you need access. The tool has some similarities with Playground/script cache, but GT tools lack the category structuring for scripts that you find in QuickAccess. It might be an inspiration for a future unified script management solution in Playground. Have fun! Bye T.
