AST Inspector
by Mark Rizun June 29, 2015

June 29, 2015

Hi, everyone! When I was exploring AST in Pharo, at the beginning it seemed a bit confusing for me how the tree looks like, or which part of code some node represents etc. As I'm working with ASTs for a while now, still not an expert ;), I decided to make a simple AST Inspector for myself and everyone that needs it. Hopefully, this inspector will make peoples lives easier when learning ASTs. For now its very raw. Inspector shows the code and its AST representation visually like in the picture. Also you can select/deselect a nodes of AST an see which part of code it represents (like in the picture above). Functionality ends here :) What do you think about it? Maybe you guys have some cool ideas for this inspector? <http://forum.world.st/file/n4834638/AST_Inspector.png> Cheers, Mark -- View this message in context: http://forum.world.st/AST-Inspector-tp4834638.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

RESTful API with Pharo with Gemstones
by sergio_101 June 28, 2015

June 28, 2015

I have been a project coming up that I really onlyneed a restful API on. The front end will be first built on a mobile device(iOS )then back on possibly android, with a very stripped down web application. i would like to use pharo/gemstones as the database. is there a project out there that allows for such restful API development in pharo land? This would be so fun! thanks

Data Week: A week long workshop on data visualization using Pharo and Roassal
by Offray Vladimir Luna CÃ¡rdenas June 27, 2015

June 27, 2015

Hi all, All this week we have been doing a workshop on data visualization using Pharo and Roassal on Grafoscopio. It started on last Monday and will end on next Saturday. Details are on [1][2]. The experience so far has been really gratifying and enjoyable. Newbies (with no background on programming and/or Smalltalk) liked the language, the Roassal capabilities and galleries and the inclusion of GT-Tools help a lot with code learning and exploration. I was planing to announce this before the event, but I had a really busy week and even I planned to aski for help with bugs or other questions, but so far we had only minor glitches. [1] http://mutabit.com/dataweek [2] https://twitter.com/hashtag/DataWeekCo?src=hash So, thank all the community once more for your awesome work. Now that Alexandre and others talk about "the blues" because of absences on GitHub or SO, it important to talk about this small, significant and even life changing experience that happens on next door, thanks to what you have make possible. Let's not forget that. Cheers, Offray Ps: I will follow this thread with some questions that rose on the workshop. I was thinking on asking the participants to share their questions on SO, so may be is time to do it... We will see tomorrow.

Hi we are giving some skype lectures to cameron students with damien. A fun experience, because the network is so bad that I cannot demo Pharo interactively. But I'm learning from it. Stef

Status of Twitter (api/analysis/visualization) in Pharo?
by MartinW June 25, 2015

June 25, 2015

Hi, I want to do some interaction with the Twitter API (retrieve tweets based on hashtags mostly) and visualize results of some analyses using Roassal. I saw there are some projects on Smalltalkhub, but none has much/any/up-to-date documentation. What is the current status of these projects? Does anyone know about any up-to-date documentation or examples? I am thankful for all hints. Best regards, Martin. -- View this message in context: http://forum.world.st/Status-of-Twitter-api-analysis-visualization-in-Pharo… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

the importance of your story
by Tudor Girba June 25, 2015

June 25, 2015

Hi, I gave last week a talk at NDC Oslo on "Don't demo facts. Demo stories!". While the talk is less technical, I did exemplified the message by demoing Spotter in comparison with the search support from Eclipse. There are several things I would like to emphasize. I compared our solution with an "industry standard" one. We often think our system as being niche and perhaps not mature enough. We need to change that perception about our work. We build state of the art. One thing that I did not mention explicitly in the talk is the size of the implementation. The Spotter implementation is 3500 lines of code -- and that it is so large because it currently comes with its own widgets. Furthermore, the extensions average 8 lines per custom processor (including the method header and the pragma). This is orders of magnitude smaller than what is typically out there, and it is precisely the reason why we can compete even if we are fewer. But, to get out there and compete we have to set that high goal for ourselves. For example, with GT we do not want to compete. We want to outcompete. So can you. While details are important, high goals require us to get away from those details. Only polishing details will tend to limit you to incremental improvements. We need to jump from time to time. But, these jumps are hard. On the one hand, it is hard to find the right jump and convince people to jump with you. On the other hand, they are hard to predict. For example, Spotter would have not been predictable one year ago. Yet, dry goals are not enough to keep us going. We need stories that make us dream. And the beauty is that Pharo breaths such a story. We should not limit ourselves to that story only. For example, with GT we want to reinvent the developer experience by making the developer be able to mold visual tools to her context because that is the only effective way to build sustainable systems. This little point of view will turn the IDE upside down, and this is only possible in a system like Pharo. Choose your high goal and tell its story through the system that you build. And remember that Pharo already offers a beautiful story to start from. Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"
