Playground auto-save?
by Hilaire July 22, 2019

July 22, 2019

Hi, I have to admit it is working randomly in P7 with Dr.Geo. (19.06 rel) Sometime script can be retrieved with the playpage button other time no: executed script can not be retrieved. Its behavior is not predictable and it is a problem for me and the kids playing code. Hilaire -- Dr. Geo http://drgeo.eu

Hello everyone, Next week I'm consulting with mentors on how to design an API for Tree data structures. I was researching a bit and wrote this blog post as a starting point: https://pharokeepers.github.io/pharo/2019/06/30/Application-Programming-Int… Feedback and ideas are more than welcome :) Best regards, Smiljana Knezev

Re: [Pharo-users] [Pharo-dev] Information on Spec development

Spec 2 was integrated in Pharo. Here is the changelog: https://github.com/pharo-project/pharo/pull/3667 We will wait a few weeks before reverting all the changes to Spec 1 in order to let people who started to develop in Spec in Pharo 8 migrate to this version. -- Cyril Ferlicot https://ferlicot.fr

Re: [Pharo-users] Python bridges
by Julien June 28, 2019

June 28, 2019

I know a little Kilonâs bridge as I used it as backend for Python3Generator [1] in the beginning. To my understanding , the difference is that Atlas is lower-level than PythonBridge. Basically, Atlas allows one to send python string and get back the returned value if it is a primitive type (int, float, str, etc). PythonBridge uses Python3Generator as DSL to build valid Python code. Atlas expects regular Pharoâs string. PythonBridge provides debugging facilities, Atlas does not to my knowledge. PythonBridge provides facilities to map Pharo classes to Python classes, Atlas does not.

Generating changelogs for projects
by Cyril Ferlicot D. June 27, 2019

June 27, 2019

Hi, Since I maintain multiple projects I have some tricks to reduce the "administrative load". Here is a blog post where I explain how I am using Iceberg features and some conventions to be able to easily generate the base for my changelogs: https://medium.com/@cyril_98037/pharo-projects-changelogs-generation-based-… There is no tool to install and produce most of the changelog in a readable format. This can also be used to generate some reports about work done. I hope it can help some of you :) Have a nice day. -- Cyril Ferlicot https://ferlicot.fr

Sang did something similar a while ago too. https://github.com/lxsang/SystemProcess <https://github.com/lxsang/SystemProcess> It allows an image to launch workers. One thing interesting is that they share virtual memory, so they can exchange data during the execution Noury > On 27 Jun 2019, at 06:26, Alexandre Bergel via Pharo-users <pharo-users(a)lists.pharo.org> wrote: > > > From: Alexandre Bergel <alexandre.bergel(a)me.com> > Subject: Re: [Pharo-users] Anything on Pharo that would be like Opentalk on VW? > Date: 27 June 2019 at 06:26:32 CEST > To: Norbert Hartl <norbert(a)hartl.name> > Cc: Any question about pharo is welcome <pharo-users(a)lists.pharo.org> > > > I do not know what is ImageWorker, but DMirror is a simple and efficient way to distribute a computation on single CPU. > > Alexandre > >> On Jun 25, 2019, at 3:05 PM, Norbert Hartl <norbert(a)hartl.name <mailto:norbert@hartl.name>> wrote: >> >> >> >> Am 25.06.2019 um 20:44 schrieb Alexandre Bergel <alexandre.bergel(a)me.com <mailto:alexandre.bergel@me.com>>: >> >>> Hi Jerry, >>> >>> We have worked on bridging Pharo with Python.
