Re: [Pharo-dev] Making screenshots programmatically for book

I haven't given the way to integrate this in the Pillar workflow enough thought. I need new pictures when: - I don't have any yet; - Possibly when the text changed; - When the image changed; - With a different UITheme. For web applications, I need to integrate with something like Selenium Webdriver to get browser screenshots Stephan Verstuurd vanaf mijn iPhone

Installing Rubric
by kilon alios May 21, 2014

May 21, 2014

Besides the reported problem of configurationsOfRubic not working as every class method returns an error I have also a problem with RubicTextAreaDecoratorExample package that seems to missing some dependencies and it particular "This package depends on the following classes: PPCompositeParser You must resolve these dependencies before you will be able to load these definitions: RbEPersonColorizer parseAndShowInAWorkspace attribute attributeList attributeValue blanks identifier person personKW registry start '' Also I tried the RubTextFieldExample open, it creates the text field and I can put text inside it but if I press ESC it sends a MNU: RubTextFieldExample>>menu. Right clicking too sends the same messages as well .

Re: [Pharo-dev] Roassal2 starting point
by Alexandre Bergel May 21, 2014

May 21, 2014

Hi Uko, Roassal2 has not been officially announced and released. The reason is simple: Roassal2 targets an audience larger than the Pharo/VW/Amber communities. We would love to see Journalists, Data scientists, Artists, Educators and software engineers enjoying our tools. However, we have to be ready to expose Roassal2 to the World. There are many missing pieces: the font problem has to be solved, we need for a proper documentation, need more sexy examples, nicer integration on the webâ¦ Roassal2 is largely compatible with Roassal1. However, you probably want to do some significant rewriting to benefit from all the cool animations, color fading, fancy interactions, and much more. We do not have much documentation so far. It will soon come. A book is currently being written (by the way, I am looking to see the effort of Pillar). A large Chilean crew will be present at esug to demonstrate Roassal2 with fireworks and trumpets.

This code allows me to generate some screenshots. The exporter deletes the old picture, if it exists. |directory exporter window bounds | directory := FileSystem workingDirectory / 'pictures' . directory ensureCreateDirectory. exporter := DOScreenshotExporter new. exporter directory: directory. exporter writeWorldAs: 'world.png'. window := DOPartiesList new openWithSpec window. exporter writeMorph: window value as: 'PartiesList.png'. bounds := window fullBounds. exporter writeMorph: window value rectangle: (bounds insetBy: 20@20) as: 'PartOfPartiesList.png'. window close.

NativeBoost and WKHTML

That is why I am asking: why this road and not the other >? Short Answer: So you know the usual "Pharo does not yet rule the world" and the usual "designers do not yet code in Smalltalk" discussion ;) Long Answer: You half-way answered yourself "if we can do it directly in Pharo ..." which could be answered with "not yet out of the box". It's not that I dislike the Artefact "Smalltalk only" approach. In fact I have contributed also to this project (cleaned and refactored it) and use it for simple stuff. Still there are some small issues remaining (no support to embedd fonts, etc). Also there is no "visual template editor" - so currently you have to "code your layout". So very often using HTML and CSS for an easy and good looking print is much better and easier to do than manually code each box, line, text manually. Also there are tons of visual HTML Editors, HTML is easy to generate and CSS allows you to style. If you work with Seaside then you also already have the HTML. So far there is no HTML/CSS to Artfeact project and it would not be easy to reimplement such a beast (if done for all possible cases). WKHTML uses the QT Webkit rendering engine and we do not have to reinvent the wheel. I fully understand that the native library is not as portable as a ST only solution but we already provide and use Cairo, Freetype and others with the default Pharo release. WKHTML is LGPL so if I understand correctly there is no conflict in using and redistributing. Bye T.

Magritte versions
by Diego Lont May 21, 2014

May 21, 2014

Hi all, We would like to have more communication about the Magritte configuration. We will start by describing the current state, as far as we know it. The current released version of Magritte is 3.1.3. This versions contains the latest changes and is a release version, so should not be changed. Please use #release3.1 in referring to this version, to allow for minor updates and bug fixes to be automatically integrated. The #release3.0 is also maintained, as this refers to #release3.0 of Seaside. And as long as #release3.1 of Seaside is not released on Gemstone, I will maintain this version. There is also versions 3.2. We do not know why this version is created. It uses a duplicate baseline (only the Grease version differs), and no big changes for Magritte are planned (to my knowledge). So we propose to remove this version. If you want this version to be kept, please reply this mail with a reason. Version 3.2 is outdated, but it implies to be more recent than 3.1.3. For the time being I will only remove the 3.2-baseline, as it is duplicate. If I do not receive a mail saying 3.2 should be kept, I will remove this version beginning of June. For development I will create a version 3.1.4. I will also point #development to this version. Discussion on Magritte List. Cheers, Stephan and Diego

Fixing configurations: XML-Parser
by Stephan Eggermont May 21, 2014

May 21, 2014

XML-Parser did have breaking tests in Pharo 2, due to the use of selectorsInCategory:. This method is defined on TClassDescription. We added a package XML-Pharo2-Parser containing a copy in an extension method on TClassAndTraitDescription. It might be useful to add to Pharo 2. Diego & Stephan

NativeBoost and WKHTML
by Torsten Bergmann May 21, 2014

May 21, 2014

Hi, tried to wrap the WKHTML library (wkhtmltopdf.org) with NB to easily generate a PDF using HTML from Pharo. I think this could serve as an easy printing solution for Pharo. Code for an initial wrapper is on http://smalltalkhub.com/#!/~TorstenBergmann/WKHTML2PDF with a simple class calling the component using NativeBoost. See class "WKPDFLibrary example" I used Windows and the wkhtmltox.dll. The C example I follow with only a few function calls is very simple and can be found at the bottom of: http://m.blog.csdn.net/blog/pengqianhe/8089007 The component is called, I get correct structs in return - but still no PDF file is generated. Currently I cant see the forest for the trees. Maybe someone can have a short look what I'm doing wrong. Thanks in advance T.
