[Newsletter] Content Needed
by Marcus Denker April 12, 2018

April 12, 2018

Hi, The Pharo Monthly Newsletter is working quite well. https://newsletter.pharo.org <https://newsletter.pharo.org/> We now reached a level where it is not just 3 things, but much much more.. of course this comes with a downside: - Sometimes topics that would be worth a small article are just posted as a one-liners - I forget / overlook things for sure (so much happening!) If you want your (or some other project or topic) to be in the newsletter â> send me a mail, in the best of all cases with a fully written text that you want to have posted. This includes: - new libraries and projects - dates - high level description of existing projects - videos - Blog posts - books - lectures - Success Stories of all kinds (nice to present your Company!) - Research (e.g. published papers or project descriptions) - Expanded versions of news posted as one-liners before - â¦. There is a explicit jobs section, too. Marcus

IdentityDictionary reset
by Trussardi Dario Romano April 11, 2018

April 11, 2018

Ciao, in the Pharo 4.0 image i have a IdentityDictionary with ten items. Now when i reset the dictionary the system behaves as follows: Version A) resetAllLocks locks keysAndValuesDo:[:k :v | locks removeKey: k ifAbsent: [self halt]] Not all items are removed fro the dictionary. Version B) resetAllLocks locks keys do:[:k | locks removeKey: k ifAbsent: [self halt]] All the items are always removed. Considerations about it? Thanks, Dario

GemStone/S on Docker?
by sergio ruiz April 10, 2018

April 10, 2018

Has anyone set up GemStone/S on Docker? I have another project that I need persistence on. In the past, I have use voyager, but Iâd really like to use something that doesnât require refactoring. I was looking at Magma, but it looks like that is Squeak only. ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.codeandmusic.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Hello, I don't know how to report that but for several weeks (maybe months), I can't reach the "News" section of the website (I have tried from several locations with different ISP). I usually get a timeout error (error 524 from Cloudflare) that comes from pharo.org. Mathieu

[ann] gt diagrammer
by Tudor Girba April 8, 2018

April 8, 2018

Hi, We are happy to announce an initial version of GT Diagrammer, an engine for constructing diagrams interactively. This is the newest addition to the next generation GT built on Bloc. It looks like this: https://twitter.com/feenkcom/status/976341449267531776 We chose to work on Diagrammer for multiple reasons. First, developers often need to create hand built diagrams to communicate intentions, and an integrated experience should not require us to leave our environment to create them. At the same time, Diagrammer is an application that requires a widgets and interactions, and thus it is a nice exercise for Bloc and Brick. One requirement we had from the beginning was to make it work with any Bloc element. This means that the editing part had to be reasonably generic. To this end, we now have elements that can define visual editors. This is somewhat a combination between Magritte descriptions, and inspector extensions. An interesting side effect is that now we can edit visual properties when inspecting any element. In other words, we got the basic infrastructure of a UI painter. It looks like this: https://twitter.com/feenkcom/status/982656456968241152 The user interface essentially relies on two widgets: scrollable list and toggle button. While the visual look of the toggle button is inspired from material design, the most interesting part is that now we have an implementation for controlling looks per element instance. A key issue here is that looks can react to events coming from the element and inject visual attributes and possible even change behavior (for example, changing an icon while pressing a button). We will post more about looks soon. We now also have a nice solution for overlays. For example, we have an overlay showing selection and an overlay for resizing elements. Perhaps less obvious, Diagrammer also offers a basic infrastructure for the area of visual languages. As Diagrammer works with any Bloc elements, we can simply create dedicated visual elements. As an example, Diagrammer comes with an implementation of a UML class figure. Furthermore, as the functionality does not impose a specific model, custom language semantics can be mapped on visual actions. There are several things to do still for it to become a mature solution. An important next step is to serialize a diagram scene in a reproducible manner. Currently, the diagram (or any element) can be exported as pdf (https://twitter.com/feenkcom/status/976580153802358786) svg (https://twitter.com/feenkcom/status/976578060429484032) png, gif or jpeg by directly using the low level canvas. However, for the diagram to be truly useful we need to store the result in either code or another reloadable form such as STON. Other future directions are related to figure controlling (for example, custom anchors or line bending points) and to enhanced editors. To play with it, the easiest way is to download the new GT in a Pharo 6.1 image: Metacello new baseline: 'GToolkit'; repository: 'github://feenkcom/gtoolkit/src'; load. And then inspect: GtDiagrammerElement new Cheers, The feenk team -- www.tudorgirba.com www.feenk.com "Presenting is storytelling."
