Hi sean I have the impression that this is related to a hiccup of smalltalkhub. I'm about to get rid of Magritte in Pillar.

Re: [Pharo-dev] call for help: answer on HN :)

by Dimitris Chloupis

yeah the guy (martin whatever) is a troll, if I remember correctly its the same dude we had on the reddit forum for Smalltalk that has been attacking Pharo with pure lies. He is a typical troll that blows off steam by annoying other people. I am with Stef with this one, the only way to win against a troll is silence. I had a very recent experience where the person in charge underestimated a troll, he overflown the mailing list with negative, many people took the bait and tried to have a civilized discussions with him, he drag it one for month until people started abandoning the community and the community essentially died. I adviced them not to feed the troll but as in many other cases, people dont even listen. Pharo is far from perfect, but this is not a logical discussion , its pure troll tactic. Do not underestimate the power of a troll, it is more powerful than you can imagine and feed on politeness and rationality. Don't feed the troll.

I would really dream of a stable, correctly interruptible (i.e. a Cmd-. that really works), limited Pharo core. That would help development so significantly and allow more experiments. I solve that by making stuff that distance itself as much as possible from a lot of the Pharo stuff that evolves far too much, far too fast to be relied upon (widgets, graphics, editors), and I'm looking forward to building a limited(*) image with just and only the things I rely on.

[ann] gt diagrammer

by Tudor Girba

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."
