[Glamour] default selection in ListPresentation
by Cyrille Delaunay 24 Mar '18

24 Mar '18

Hello, Is there a way to set a default selection to a list presentation? so that when I open the browser, the morphic list has already a value selected. I tried that: |tmpBrowser| tmpBrowser := GLMTabulator new. tmpBrowser row: #list. tmpBrowser transmit to: #list; andShow: [:a | a list display: [:input | input]; selection: #a; yourself ]. tmpBrowser openOn: #( b c d v a d f r). but the list still open with nothing selected

Delegating views
by Luke Gorrie 21 Dec '17

21 Dec '17

Hoi, What is the best way for an object to delegate one or more GTInspector views to other objects? I have been using a pattern like this: gtInspectorFooIn: composite <gtInspectorPresentationOrder: 5> otherObject gtInspectorFooIn: composite but I am wondering whether there is a better way, and also whether this method is valid (I've occasionally seen odd behavior, like Inspector panes disappearing after I "Refresh", and I wonder if I could be somehow confusing the model or if this is not relevant.) also: Supposing this pattern is valid, is there an easy way to override the title of the view(s) added by otherObject?

[ann] gtspotter: a moldable interface for spotting objects
by Tudor Girba 23 Sep '17

23 Sep '17

Hi, Alex Syrel, Andrei Chis and I are happy to announce a new addition to the Glamorous Toolkit: GTSpotter, a novel interface for spotting objects. GTSpotter has two goals: - Provide a uniform yet moldable interface that can work on any object, and - Handle searching through arbitrary levels of object nesting. We think this will have a significant impact on the development workflow in Pharo. Here is a couple of screenshots: [image: Inline image 2] [image: Inline image 1] [image: Inline image 3] A trailer is available here: https://www.youtube.com/watch?v=PhSmjR3NOlU A detailed description is available here: http://www.humane-assessment.com/blog/introducing-gtspotter It works already in Pharo 3.0 and can be played with by following the instructions from: http://gt.moosetechnology.org Please let us know what you think. Enjoy, The Glamorous Team

[ann] moldable editor - with expandable elements
by Tudor Girba 27 Aug '17

27 Aug '17

Hi, We are really pleased to announce another major advancement in the development of the moldable editor, and most of it was enabled because of one new feature: expandable elements. We think this will impact significantly our day to day interactions. To exemplify what we mean, we will make use of two more alpha projects that we did not announce yet: GT Documenter (a set of documentation tools based on Pillar and GT Examples) and GT Mondrian (the graph visualization engine), both of which are being implemented in Bloc. Please take a look at the following pictures showing the documentation Pillar file that ships together with GT Mondrian. What stands out are the two embedded pictures. These are actually not pictures, but visualizations rendered live during the viewing of the document out of a referenced GT Example. Now, GT Examples are likely also new for most people. We introduced them a couple of years ago based on the original idea of Markus Gaelli. These are a kind of tests that return an object and that can be built out of other examples. The nice thing is that they are always executable and testable. So, of course, if you see the resulting object, you can also see the code that created it, and if you see the code, you can even execute it live, right in place (notice the preview of the second snippet). Perhaps the most controversial part of GT Examples is that they offer a mechanism to define static dependencies via pragmas. Please, let’s leave this debate to another occasion, but please also notice that tools can use that static information to unfold the code of the referenced method (notice the nested code editors). A side note: if you look closer at the list with three items at the top of the Tutorial section, you will notice numbering next to #. That is actually syntax highlighting and so is the mechanism that embeds the expandable elements. It’s really cool. Taking step back, when we introduced the editor a few weeks ago, we called it moldable because we said we can make it take different shapes easily. GT Documenter with everything you see in the above screenshots has currently ~500 lines of code, and all this while still having an editor that is highly scalable. We think that Bloc and Brick will change dramatically face of Pharo and now we can start to get a glimpse of what is possible. For example, the use case presented above is more than a technical tool, and we think this will change both the way we write documentation and the way we consume it. All these will be presented at ESUG both during presentations and at the Innovation Awards competition. In the meantime, those that want to play with it can execute the following in both Pharo 6.1 and Pharo 7.0: Iceberg enableMetacelloIntegration: true. Metacello new baseline: 'GToolkit'; repository: 'github://feenkcom/gtoolkit/src'; load. And then inspect: './pharo-local/iceberg/feenkcom/gtoolkit/doc/mondrian/index.pillar' asFileReference Cheers, The feenk team -- www.tudorgirba.com www.feenk.com "Innovation comes in the least expected form.

That is ok :) Those are not used modules and can be ignored. I am glad it worked! I will see, maybe it is possible to get rid of at least one gtk dependency.

PetitParser / YAML in Pharo 6.0/6.1?
by H. Hirzel 21 Aug '17

21 Aug '17

Hello Who can help to get a Pharo 6.0/6.1 catalog entry for PetitParser and YAML? Who is maintaining PetitParser? I successfully did a manual installation Repository: MCSmalltalkhubRepository owner: 'Moose' project: 'PetitParser' user: '' password: '' I loaded Name: ConfigurationOfPetitParser-TudorGirba.80 Author: TudorGirba Time: 13 September 2016, 9:59:15.01645 pm Then ConfigurationOfPetitParser load All 232 tests are green for PetitTests-Core and PetitTests-Tests For YAML parsing I loaded PetitYAML-PhilippeBack.11 Author: PhilippeBack Time: 29 May 2017, 12:53:55.994195 pm from the same repository. All 76 tests are green. How do these two packages get a Pharo 6.0/6.1 ** catalog entry? Regards Hannes ** The entry should be marked as '6.0'. The image has an 'about information of Pharo 6.0-60510 and on the desktop it shows 6.0. But the same image has been announced as version 6.1.

[ann] moldable editor - syntax highlighting ... with a twist
by Tudor Girba 16 Aug '17

16 Aug '17

Hi, After another intense week, we are happy to announce that the Brick editor now supports some advanced syntax highlighting. To put it in perspective, let us take a look at one screenshot showing an inspector presentation containing a Brick editor opened on a Pillar file that includes some text, a code snippet and a reference to a picture: This shows both that we style the text based on the Pillar grammar, but also that we can style Smalltalk code (in fact, we have two nested stylers here). But, the more interesting thing is that below the picture reference, we get to see the actual picture (which happens to be another inspector screenshot). In fact, this picture is actually just another text attribute (we call it an adornment) that can be dynamically added to any text elements. This opens up a whole lot of expression power and it is all easily compose-able. This is another reason why we say that this editor is moldable and you should expect new applications making use of this moldability and combining it with the liveliness of Pharo. The latest Brick code is loadable through: Metacello new baseline: 'Brick'; repository: 'github://pharo-graphics/Brick/src'; load: #development. If you want to play with Pillar, load the following extra code and just inspect a Pillar file: Metacello new smalltalkhubUser: 'Pier' project: 'Pillar'; configuration: 'Pillar'; version: #development; load. ((IceRepository registry detect: [ :each | each name = 'Brick' ]) packageNamed: 'Brick-Editor-Pillar') loadLatest. One other thing to mention is performance. What Alex (Syrel) managed to do is quite remarkable. To see the impact in practice, try editing the largest method in Pharo (UnicodeDefinitions class >> #data) in both the built-in editor and in the Brick editor by inspecting: BrTextEditor onMethod: UnicodeDefinitions class >> #data There are still issues left to deal with and we will focus on them in the following weeks. But, we can safely say that the most important challenges are now behind us and that the design of the editor code is stable and robust. Please do let us know what you think.

Is this still an issue? Could you also try on another OS (just to make sure)?
