Re: [Pharo-dev] Creating the smallest server runtime footprint

I really appreciate your patience and help on this - it looks very promising and I am giving it a spin nowâ¦ When you say the pharo repository - are you referring to this: https://github.com/pharo-project/pharo/tree/master/src <https://github.com/pharo-project/pharo/tree/master/src>. ? Just so I know for the future.

Re: [Pharo-dev] Creating the smallest server runtime footprint

by Pavel Krivanek

The easiest think you can do is to copy to your repository (or some other) related packages from the Pharo repository (to do not have to clone it all): Metacello-GitBasedRepository.package Metacello-GitHub.package SUnit-Core.package and create baseline to load them. I already tried it so you can test it: https://drive.google.com/open?id=0BzSsmZhqtUTeMVJacTZtdW5UQW8 Then you will do something like: 2017-08-02 15:18 GMT+02:00 Tim Mackinnon <tim(a)testit.works>: > Ah, I think Iâm starting to get closer to what I needâ¦ > > So if I want to load in that last piece to enable more general remote > loading - how do I figure out how to do that?

Live Programming in Smalltalk development environments survey + raffle

by Juraj Kubelka

â âWe are apologize for multiple copies.â â Dear Smalltalker, Live programming frees developers from the "edit-compile-run" loop and allows people to interact with running programs very easily. Live programming is getting popular, but many of its features have been present in Smalltalk for a very long time. We want to understand how Smalltalk software developers use live programming features in practice. We would be grateful if you could participate in our 10-minute survey on this subject: http://bit.ly/2ufcg2D <http://bit.ly/2ufcg2D> As a thank you for your participation, you will be able to participate in a raffle to win a Smalltalk book of your choice. If you wish to participate, you will need to share your email with us, so that we can contact you. We will appreciate if you share the survey - Twitter post: https://twitter.com/JurajKubelka/status/893006267085709312 <https://twitter.com/JurajKubelka/status/893006267085709312> - Facebook post: https://www.facebook.com/juraj.kubelka/posts/10212505941300008 <https://www.facebook.com/juraj.kubelka/posts/10212505941300008> By participating in the survey you will: - help me to successfully finish my PhD, - push Smalltalk awareness in Live Programming research community, - bring new integrated electronic communication ideas, and - bring new ideas to improve our Smalltalk Live Programming experience :-) We will close the survey on Wednesday, August 9, 2017 AoE. Thank you and we really hope you enjoy participating in our survey!

Question about Bloc

by Alexandre Bergel

Hi! We were wondering whether someone did some workload with Bloc. How many elements can Bloc render, at the same time? Is there a support for Quad-Tree ?

Re: [Pharo-dev] Creating the smallest server runtime footprint

by Tim Mackinnon

As an aside, Iâve just noticed that I get the same error in a normal 6.1 image when you try to load a baselineof package in Iceberg using the install menu option. So I wonder if this might actually be a bug in the image that the minimal version is getting as well?

OR is there something simple I can checkin and load locally to return that behaviour? (Personally I think it would make sense to allow remote loading - Iâm guessing Pharo itself as a core has everything it needs - but if you want to do any experimentation on the core and need remote packages, you would hit this too - so it feels a bit limiting). > > Tim > >> On 1 Aug 2017, at 10:06, Pavel Krivanek <pavel.krivanek(a)gmail.com <mailto:pavel.krivanek@gmail.com>> wrote: >> >> >> >> 2017-07-31 22:51 GMT+02:00 Tim Mackinnon <tim(a)testit.works <mailto:tim@testit.works>>: >> I wasnât clear on which image to retry - the https://ci.inria.fr/pharo/job/Pharo-6.0-Update-Step-3.2-Minimal/lastSuccess… <https://ci.inria.fr/pharo/job/Pharo-6.0-Update-Step-3.2-Minimal/lastSuccess…> one still shows as being last updated 7 days ago. >> >> The https://ci.inria.fr/pharo/view/6.0-SysConf/job/Pharo-6.0-Step-04-01-Configu… <https://ci.inria.fr/pharo/view/6.0-SysConf/job/Pharo-6.0-Step-04-01-Configu…> one gives me a mismatch error: This interpreter (vers. 68021) cannot read image file (vers. 6521). >> >> The https://ci.inria.fr/pharo/view/7.0/job/70-Bootstrap-32bit-Conversion/lastSu… <https://ci.inria.fr/pharo/view/7.0/job/70-Bootstrap-32bit-Conversion/lastSu…> one gives me a walkback when trying to run my install script : >> >> 25 UndefinedObject(Object)>>doesNotUnderstand: #addTo: >> 26 MCRepositoryGroup>>addRepository: >> 27 createRepository >> | repo | >> repo := self project createRepository: self. >> ^ MCRepositoryGroup default repositories >> detect: [ :each | each = repo ] >> ifNone: [ >> MCRepositoryGroup default addRepository: repo. >> repo ] in MetacelloRepositorySpec>>createRepository >> >> I think this is because the image doesnât support Metacello?

These classes are not gone > just deprecated. Not just Moose, also all the packages it depends on. Included in said image, at a cursory glance; - Metacello - Fuel - SmaCC - Beacon - Fame - Grease - PetitParser2 - Roassal2 - Rubric And that's just a quick count of the *direct* FileStream references, not including the majority of cases requiring rewrites as a result of FileHandle write/readStream now returning a pure binary stream / API of Zn stream being different from old File streams.

Deprecated in 70 means slated for removal in 80 / only deprecation warnings on use in 7.0, no? So going to 7.0 will still be possible in most cases, with warnings turned off. 8.0 is where the leap will be. Stephane Ducasse-3 wrote > We would to resurrect andre automatic evolver.
