Primitive is not executed
by Jesus Mari Aguirre June 10, 2020

June 10, 2020

I am developing a "numpy arrays" like framework on pharo, I decided to use an Array type depending on the class of its elements (I thought it would be more efficient) i.e if the array contains floats it will be stored in a floatArray but if contains integers, a IntegerArray will be used. I make an extensive use of use of the method replaceFrom: start to: stop with: replacement startingAt: repStart when I do concat and other methods that imply copying but I've realize that primitive 105 is not executes when I call this method from these kind of arrays but it works if I use a normal Array. What do you suggest me to do? is it better to use the normal Array for every type of content or is it a bugg? Is FloatArray/IntegerArray more efficient in any way? If not...what is their purpose? replaceFrom: start to: stop with: replacement startingAt: repStart "Primitive. This destructively replaces elements from start to stop in the receiver starting at index, repStart, in the collection, replacement. Answer the receiver. Range checks are performed in the primitive only. Optional. See Object documentation whatIsAPrimitive." <primitive: 105> super replaceFrom: start to: stop with: replacement startingAt: repStart

PharoExtras group on smalltalkhub -> github ?
by PAUL DEBRUICKER June 10, 2020

June 10, 2020

Are there any projects in PharoExtras (or other public groups) that have not been ported to github? If they've been ported where are they now? Is there any map between smalltalkhub projects and their new locations or is it all on a project by project basis right now? Seems like there's individual mailing list messages and some notes on project sites and thats about it. IS that accurate? Thanks

Roassal and Seaside/Willow

Hello, Is it possible to integrate Roassal with Seaside/Willow? I found a project in smalltalkhub, but I don't know if it is outdated and I know smalltalkhub is being discontinued, so I am not sure if I should use it. Regards, Vitor

Thanks! Willow on top of Seaside really is the best of the world :) On Tue, Jun 9, 2020 at 1:36 PM gettimothy via Pharo-users < pharo-users(a)lists.pharo.org> wrote: > > That sounds really cool! > > Bookmarked, for my next Seaside project. > > thx! > > ---- On Mon, 08 Jun 2020 18:00:14 -0400 *Gabriel Cotelli > <g.cotelli(a)gmail.com <g.cotelli(a)gmail.com>>* wrote ---- > > Hi Vitor, > > Willow is built on top of Seaside and it aims to ease the creation of > interactive AJAX-based web applications.

Thanks Olivier You do not experiment UI glitches so this means that it probably depend on the OS version.

I recommend you to choose a recent model with a powerfull x86 processor. Them support Chrome apps, Android apps and Crostini for Linux apps. This last mode allows running Pharo on Chrome OS.

Hi, has anyone an experience with running Pharo on Chromebook (using Crostini)? It worked reasonably well for me in the past (3 months ago), now I see rendering issues: [image: image.png] I tried with latest and greatest Pharo8 and fresh image, I see the same rendering issue. Thanks, Jan

UK Smalltalk User Group Meeting - Wednesday, June 24th
by Giovanni Corriga June 8, 2020

June 8, 2020

The next meeting of the UK Smalltalk User Group will be on Wednesday, June 24th. Fabio Niephaus (https://fniephaus.com) will talk to us about TruffleSqueak ( https://github.com/hpi-swa/trufflesqueak) a Squeak/Smalltalk VM and Polyglot Programming Environment for the GraalVM (https://www.graalvm.org) He is a Ph.D. student within the Software Architecture Group ( https://hpi.de/swa) at the Hasso Plattner Institute, University of Potsdam, Germany. He has strong interests in dynamic programming languages, virtual execution environments, and software development tools. Fabio will talk about the motivation for his research in the field of Polyglot Programming. With a live demo, he will show how TruffleSqueak can be used as a polyglot IDE for other languages such as Java, Javascript, Python, R, or Ruby. He will also introduce us to the GraalVM ecosystem and discuss his experience in writing a Smalltalk VM in Truffle, GraalVM's language implementation framework. Given the current COVID-19 restrictions, this will be an online meeting. If you'd like to join us, please sign up in advance at the meeting Meetup's page https://www.meetup.com/UKSTUG/events/cbklbrybcjbgc/ to obtain the meeting details. See you there!
