AST source interval isn't changed
by Mark Rizun Aug. 14, 2014

Aug. 14, 2014

Hello, I have MyTextModel class - a subclass of TextModel, it holds an ast of it's text. When I replace node of the ast using replaceWith: ast is changed, then I say text: ast formattedCode, so the text is changed too. But! when I inspect new ast(after replacing some node), I see that source interval isn't changed. Why? If I say bestNodeFor: someInterval, it doesn't give me the right node, because sourceInterval of ast wasn't changed, and I don't know why. Hope you will help me out:) Best, Mark -- View this message in context: http://forum.world.st/AST-source-interval-isn-t-changed-tp4772779.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Issue identified, but help required! Re: Build failed in Jenkins: Pillar Â» 30,development,vm #636
by Ben Coman Aug. 13, 2014

Aug. 13, 2014

I have identified the problem with the failing Pillar CI development builds, but I'm not sure what action should be taken. "Pillar-ExporterHTML-EstebanLorenzano.47" which is commented as... "bugfix: PRHTMLWriter>>#writeEmbeddedPicture: should not add '%' to width property. That should be responsibility of author." made the following change... PRHTMLWriter>>writeEmbeddedPicture: - anExternalLink parameterAt: 'width' ifPresent: [ :width | img parameterAt: 'width' put: width greaseString, '%' ]. + anExternalLink parameterAt: 'width' ifPresent: [ :width | img parameterAt: 'width' put: width greaseString ]. ...which causes PRHTMLWriterTest (PRDocumentWriterTest) >> testFigureWithWidth to fail. It can be fixed as follows (plus some debugging instrumentation)... PRDocumentWriterTest >> testFigureWithWidth | item width | - width := '50'. + width := '50%'. item := PRExternalLink new reference: 'file://picture.png'; embedded: true; parameterAt: 'width' put: width; yourself. + Transcript crShow: self printString ; crShow: (self write: item). self assertWriting: item includesText: self widthFor50percents ...but I'm not sure if modifying #testFigureWithWidth is the right thing to do to fix PRHTMLWriterTest, since this test is inherited by six other subclasses of PRDocumentWriterTest. None of the other tests complain, but that doesn't make it right. ==================== With [width := '50'] running all Pillar tests produces the following Transcript... PRLaTeXWriterTest>>#testFigureWithWidth \begin{figure} \begin{center} \includegraphics[width=0.5\textwidth]{picture.png}\caption{file:$/$$/$picture.png.\label{picture.png}}\end{center} \end{figure} PRHTMLWriterTest>>#testFigureWithWidth <figure><img src="picture.png" width="50"> </img><figcaption></figcaption></figure> PRGitHubMarkdownWriterTest>>#testFigureWithWidth <a name=""></a><figure><img src="picture.png" width="50%"> </img><figcaption>file://picture.png</figcaption></figure> PRMarkdownStreamWriterTest>>#testFigureWithWidth <a name=""></a><figure><img src="picture.png" width="50%"> </img><figcaption>file://picture.png</figcaption></figure> PRPillarWriterTest>>#testFigureWithWidth +file://picture.png|width=50+ ==================== With [width := '50%'] running all Pillar tests produces the following Transcript... PRLaTeXWriterTest>>#testFigureWithWidth \begin{figure} \begin{center} \includegraphics[width=0.5\textwidth]{picture.png}\caption{file:$/$$/$picture.png.\label{picture.png}}\end{center} \end{figure} PRHTMLWriterTest>>#testFigureWithWidth <figure><img src="picture.png" width="50%"> </img><figcaption></figcaption></figure> PRGitHubMarkdownWriterTest>>#testFigureWithWidth <a name=""></a><figure><img src="picture.png" width="50%%"> </img><figcaption>file://picture.png</figcaption></figure> PRMarkdownStreamWriterTest>>#testFigureWithWidth <a name=""></a><figure><img src="picture.png" width="50%%"> </img><figcaption>file://picture.png</figcaption></figure> PRPillarWriterTest>>#testFigureWithWidth +file://picture.png|width=50\%+ ==================== Now would existing projects be broken by pictures becoming 50 pixels wide rather 50% wide ? If the goal is to be able to specify pixel width, maybe it would be better to introduce a Pillar parameter "pixelWidth" . Presumably the Pillar documentation https://github.com/pillar-markup/pillar-documentation would need updating also. cheers -ben

[ANN] TinyMCE for Seaside
by Torsten Bergmann Aug. 13, 2014

Aug. 13, 2014

Hi, if you want to use the TinyMCE Editor in your web application with Seaside then you should/could use this one: Project + Documentation http://smalltalkhub.com/#!/~TorstenBergmann/TinyMCE Simple Demo: http://pharo.pharocloud.com/tinymce Nothing special, just a simple file library and an example on how to use it. But maybe it safes others some time. Bye T.

Making the tree of a Moose browser editable
by Offray Vladimir Luna CÃ¡rdenas Aug. 13, 2014

Aug. 13, 2014

Hi, With the help of this community, I'm making some progress on my tree/outline like interface. By default, all text panels are editable and all trees are not, you just can expand or collapse them, but I would like to edit the text on the trees. There is any way to do it? Cheers, Offray

How to contribute to PharoLauncher?
by Tim Mackinnon Aug. 11, 2014

Aug. 11, 2014

Hi - Iâve added a few interesting features to PharoLauncher, but Iâm not sure what the steps are for contributing to a SmalltalkHub project? My proposed changes are as follows: - Change default image template name to include the parent folder name (e.g. Pharo 4.0 (beta)-540123 vs. 450123) - Add a new image command âImage Summaryâ that shows you the date of the last image modification as well as the contents of âdescription.txtâ - as I canât always remember why I have some old images kicking around (this change is quite basic - I couldnât see how best to create a nice popup window so I reused the deny: one with a new title. I did think possibly a hover over balloon or having something like the comments panel in Pharo - but its a modal dialog for now) - I changed the Run icon to a play button (as the process icon used - seemed a bit obscure) Tim

How do I trace through implementors in Pharo?
by Tim Mackinnon Aug. 11, 2014

Aug. 11, 2014

As I relearn/learn how to use Pharo, Iâm struck by some of the excellent changes and confounded by some of the simple things that boggle me. So, I wanted to follow a path through some message sends - the use of #alert:title: in UIManager specifically. So I browser UIManager, find the method (its subclassResponsiblity) - so I find other implementers (cmd+b, cmd+m) - (Iâm really liking that there are more keystrokes in newer Pharoâs but not liking that the same operations donât have the same bindings in different windows - e.g. in the debugger - its not this!!) Anyway - this gives me an implementors window on TEasilyThemed - great! In the source, there is another msg send - ^self alert:title:configure: So I want to follow its implementers - I hi light the source and cmd+b,cmd+m does nothing? hmmm - right click there and the context menu doesnât have an obvious way - until I spot (Extended Searchâ¦) [which by the way should be shown as a submenu - like it does in the SystemBrowser). In this menu there is âimplementers of itâ - however this does nothing? (this is in both Pharo 3.0 and Pharo 4.0) So how do you trace through method calls? Am I doing something wrong - or has this been broken for a long time? Tim

Can I create a personal slice?
by Tim Mackinnon Aug. 10, 2014

Aug. 10, 2014

Hi - i was playing around with some changes in a few packages to see if I can make a contribution to PharoLauncher. I want to version my spikes, in case I trash my image - but Iâm not yet ready to propose anything to commit yet. While I can version each of the dirty packages - how can I group them to load them in one go? I thought maybe I could make a quick personal slice - store it in my personal file disk repository and then load it again if something goes wrong or I want to revert. However it seems that to create a slice I need a Fogbugz number - which seems more like Iâm ready to contribute? Canât I make a personal slice? Or is this where I have to use Metacello? Tim
