Updating CI plugins
by Guillermo Polito Sept. 10, 2017

Sept. 10, 2017

Hi all, I'm updating several CI plugins related to Multibranch builds. Since Jenkins is moving fast is this direction, it is healthy that we follow updates regularly. You'll see the exact list of plugins and versions installed in here: https://pharo.fogbugz.com/f/cases/20402/Update-CI-Plugins -- Guille Polito Research Engineer French National Center for Scientific Research - *http://www.cnrs.fr* <http://www.cnrs.fr> *Web:* *http://guillep.github.io* <http://guillep.github.io> *Phone: *+33 06 52 70 66 13

Bloc Shock
by Sean P. DeNigris Sept. 10, 2017

Sept. 10, 2017

I was playing with Bloc when I came across the following: <http://forum.world.st/file/t128965/Screenshot_2017-08-31_14.jpeg> I am taken aback by the elegance and utility of this widget, and also aware of all the countless steps we took to have it appear there - Bloc, GT, etc, etc. It feels like proof of the synergy of moving one step forward every day. Thanks to all. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html

Changing pharo default branch to development
by Guillermo Polito Sept. 10, 2017

Sept. 10, 2017

As we discussed in ESUG, and since this is a cheap change to do in the airport, we are making the development branch in pharo the default branch. This will help avoiding accidental pull requests targeting master instead of development. For those who may ask, we will not remove the master branch yet. This is because we are in the airport doing this and we would like to give it a better thought :).

STON: SortedCollection Bug?
by Sean P. DeNigris Sept. 9, 2017

Sept. 9, 2017

I serialized aSortedCollection with a sort block comparing via a #startTime message on the domain objects. When I attempted to materialize it, I got an error that my domain objects don't understand #<=. It seems that the elements are being loaded before the sort block. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html

[ANN] Git Thermite
by Ronie Salgado Sept. 7, 2017

Sept. 7, 2017

Hello, I am releasing an initial version of Git Thermite, the GitHub pull request visualization that I presented at IWST. SmalltalkHub page: http://smalltalkhub.com/#!/~ronsaldo/GitHubAPI Script for loading Git Thermite: Gofer it smalltalkhubUser: 'ronsaldo' project: 'GitHubAPI'; configurationOf: 'GitStats'; loadBleedingEdge For visualizing a GitHub pull request, you can use the dialog on the World menu -> Git Thermite -> Visualize pull request. The GitHub access credential can be entered through the System Settings. I recommend to generate a GitHub API secret token instead of using your GH password for the access token. https://github.com/blog/1509-personal-api-tokens Because this project is for my Master Thesis, and I need to gather experimental data to validate the visualization, I will ask to the people at Lille to not experiment with this tool until I test it with you during the next two weeks at Lillle. The current implementation is quite hackish because I am building this in an exploratory way. Later I will make a full rewrite to clean the tool and make it easy to extend and experiment with more visualizations with it. Best regards, Ronie

[ANN] Lowtalk, a new Smalltalk dialect that could eventually replace Slang
by Ronie Salgado Sept. 6, 2017

Sept. 6, 2017

Hi All, I am finally glad to announce an initial version of my secret experiment, Lowtalk: https://github.com/ronsaldo/lowtalk Lowtalk is a new Smalltalk dialect that generates relocatable binary object code, that can be linked with any C program or used to generate a standalone executable with the C linker. I am designing Lowtalk as a language for video game developing, where performance and multi-threading support is important. The Lowtalk compiler is completely written in Pharo. The main features of Lowtalk are the following: - The compiler is actually a meta circular evaluator, whose features are used for bootstraping the Lowtalk kernel. - The Lowtalk object model, including the layout of the objects is defined in the language itself. - Direct interface with C. There is an almost 1:1 mapping between the Lowtalk native types and the C types. There is a syntax extension for calling C functions. -Support for real multi-threading. - The current object model uses automatic reference counting, which is slow, but makes supporting real multi-threading easier. - Immediates are based on the Spur object model. - Partial support for generating debugging information in the DWARF standard. It is possible to place breakpoints and get correct stack traces with gdb. Lowtalk is on the line of my work with Lowcode, and I am planning on making a Lowtalk backend that uses Lowcode. The Lowtalk type system is almost the same as the one that I described at the paper: Lowcode: Extending Pharo with C Types to Improve Performance I will make a video later, and a proper demonstration at ESUG. Best regards, Ronie
