[ANN] file dialog replacement experiment
by Peter UhnÃ¡k July 17, 2016

July 17, 2016

Hi, last week I stitched together a simple file dialog replacement and today I managed to somewhat finish it. There is still a lot to be desired, but right now it supports things that were the most pain for me: * list of most common places (home, root, image directory, temp) * custom bookmarks by dragging folders from file-pane to bookmark-pane * toggle hidden files (right-click on file listing) * preset file name * filtering files by extensions or patterns and toggling between filters * synchronous and asynchronous mode â You can use it independently of Pharo's native dialogs FDOpenFileDialog new extensionFilters: {'STON files' -> #(ston). 'All files' -> #()}; defaultFolder: FileLocator imageDirectory asFileReference; openModal Or if you feel brave, I have an extended UIManager that will use thisâ¦, and then you can use regular manager commands UIManager default chooseFileMatching: #('*.ston') but you can always go back FDMorphicUIManager new beDefault. "use new dialogs" MorphicUIManager new beDefault. "use old dialogs" and of course the installation itself (I'll add it to catalog soon after I find a way to autogenerate configurations from git tags) Metacello new baseline: 'FileDialog'; repository: 'github://peteruhnak/file-dialog/repository'; load. More info and docs on GitHub https://github.com/peteruhnak/file-dialog Any comments/feedback/bug reports is appreciated. Peter

Hi, I just updated Pharo Launcher. A new version 0.2.11 is available. Here are the change log: move Pharo Launcher to the latest stable pharo image: pharo 5.0. It implies That Pharo Launcher is now shipped with Spur VM. allow an easy download of the new beta image: pharo 6.0 the Launcher now comes with 2 VMs: Spur VM (pharo 5.0 and Pharo 6.0) Non-Spur VM (to be able to run old images) the Launcher is now shipped with a default template that is the current default Pharo image. It can be found in local templates. there is a new OS bundle for linux: we now ship more files with the launcher and it was needed to have a bundle. update of the default name propose when you create an image from a template: the default name will be the project name. If you want to give it a try, executables are there: windows: http://files.pharo.org/platform/launcher/blessed/pharo_installer-0.2.11.exe <http://files.pharo.org/platform/launcher/pharo_installer-0.2.11.exe> mac: http://files.pharo.org/platform/launcher/blessed/Pharo_0.2.11.dmg <http://files.pharo.org/platform/launcher/Pharo_0.2.11.dmg> linux: http://files.pharo.org/platform/launcher/blessed/Pharo-linux-0.2.11.zip <http://files.pharo.org/platform/launcher/PharoLauncher-user-0.2.11-2016.05.…> Christophe.

Failing to create a project on SmalltalkHub
by Victor RENE July 10, 2016

July 10, 2016

http://smalltalkhub.com/#!/~VictorRene I am trying to create a project on Smalltalk hub to save progress on the MOOC. But it fails with "incorrect username or password", and i can not logout. Okay, I can probably empty my browser cache but it's still incorrect behavior. Also, they say it's possible to use Git but they don't describe the setup. Any ideas? Thanks in advance.

How do I convert a FileTree project to Metadataless GitFileTree project?
by Dale Henrichs July 5, 2016

July 5, 2016

Thierry, I think I tried the obvious: 1. open existing repository with gitfiletree:// 2. reload all packages from gitfiletree repo and remove old filetree:// repo from each package 3. edit .filetree and add `"Metadata" : "false"` but when I save a package I continue to get metadata created ... I even tried removing and adding the repo after editting the .filetree file .... I have a handful of additional random things that I will try, but I think it is also time to find out the proper technique:) I want to gain experience with GitFileTree; test out the Metacello Cypress mode; and perhaps honor the `"Metadata" : "false"` in the GemStone version of FileTree ... With a short time of usage, I would really like to be able to save all of the packages in a project (including the BaselineOf) in one commit ... I often have multi-package units of work that really should be committed together and of course if a method is moved across a package boundary, the independent commits don't allow git to recognize the move as a "rename" ... Also I'm hoping that in metadataless mode I stop scanning the entire known repository universe for package versions that will not be found anywhere but in the repositories that I've explicitly associated with the the package itself:) Thanks, Dale

[ANN]Windows previewer / switcher for Pharo
by Julien Delplanque July 3, 2016

July 3, 2016

Hello, This mail to announce you that I am working on a windows previewer / switcher for Pharo [1]. It is still in early stage of development but it is usable. To install it: |Metacello new repository: 'github://JulienDelplanque/WindowsPreviewer/repository'; baseline: 'WindowsPreviewer'; load| See the README for details on activation/shortcuts. Please, if you have some ideas or critics let me know! Also, a better name than "Windows Previewer" would be cool but I have no other idea :-)...

Styling a Pharo UI application
by Tommaso Dal Sasso July 2, 2016

July 2, 2016

Hello everybody, I have a question about the UI toolkits available for Pharo. I already asked something about this on Slack, but since I saw that there was a recent discussion about UI in the mailing list, I think this is a better place to discuss the matter. I am writing an application for Pharo where I am displaying some structured text. The structure is similar to the one of a web page: A main title with a list of paragraphs, where each paragraph has a title and a description. What I would like to do is to format the text to present the contents in a meaningful way: For example, I would like a bigger font for the title, and change the background of the text, to give a better separation between the paragraphs. Basically I would like to manipulate and display my contents as I would do in a web page. To write UI widgets I usually use Spec, but I found that going beyond easy formatting (e.g. bold text and emphasis) is harder than I thought. I saw there were discussion about the styling text and the role of the theme class, using TextStyle but that part is not really documented. So far, the easiest way to solve my problem seems to be to use Morphic to display the contents as I want it, and then include my widget in my spec application. Do you have any suggestions about how to do that? I think that styling the UI widgets is an important part of the application development, but it is really hard to find documentation about this. Thanks, have a nice day! Tommaso

Provide a mapping for a collection of <Association>s in NeoJSON
by PBKResearch July 1, 2016

July 1, 2016

Hello I have recently used NeoJSON for the first time. All went pretty well, but I would like to make a small tweak to the output, which probably involves defining a mapping. I have read through the information in the NeoJSON pdf, and also looked at the class comments, but I am a bit lost. Could Sven or anyone please give me a hint? What I want is to construct a JSON object as a Pharo dictionary, but then control the order in which the fields are output to the JSON file. Clearly the order is irrelevant for a computer, but it could be helpful to a human reader to put them in an order which reflects the way humans think about the objects. The keys of a dictionary are of course unordered, so this is not possible, but if we step back a bit we see that a dictionary is often constructed from a collection of associations; if we could stop at this stage, and have a mapping which outputs the associations in the order in which they appear in the collection, this would give the control I am looking for. Am I talking nonsense, or is there any way of implementing this using NeoJSON mappings? Best wishes Peter Kenny
