New Iceberg Version 1.2.1

New Iceberg Version 1.2.1 [ https://github.com/pharo-vcs/iceberg/releases/tag/v1.2.0 + https://github.com/pharo-vcs/iceberg/releases/tag/v1.2.1] Thanks to all brave users, issue reporters, and contributors :). This version includes the implementation of projects. Projects are a way of defining basic metadata of the repository. Now, this metadata just includes the source directory. This means that people do not need anymore to provide ALL THE TIME the source directory. Instead, every repository includes a project file that provides it. Iceberg will guide people to create the given file. This file is managed by Iceberg and people should not touch it from the outside or accept the consequences :). This version is integrated in the latest Pharo 7 images. #New Features - #866 Introduce first version of Projects #Infrastructure - #870 Improving tests of Metacello Integration - #903 Split basic tests from metacello tests in CI - #914 Sync Wiki with documentation directory automatically - #934 Manually check metacello integration dialogs - #935 Try to refrite the metacello integration tests. - #940 Installation in new Pharo should also bootstrap pharo repository #Enhancements - #675 The History of a Method in Calypso should show a progress bar. - #788 Show progress during network operations (fetch,push, ...)

Hi Evan, yes exactly. the defaultÂ if i dont change & _store_ settings is: i make via launcher a pharo6.1blabla, it has its own repository-directory; i make the next one, pharo6.1blabla-01, open monticello and it has another package-cache. i did not test this, but i guess it could be possible that if you store settings just once even _without_ changing anything, the local cache directory will be stored, as the class-var-accessor produced a valid path, and from then on this setting will not change anymore for new builds via launcher. you either reset the settings via deleting the monticello records in the settings file found via StartupPreferencesLoader preferencesVersionFolder. or if you need to store changed settings in a general way eg for all 6.1 versions, you do that deleting afterwards. i agree that the 2 monticello-settings behave differently and that this is either irritating or probably a bug (because the second behaviour can make storing other settings difficult), but then <shrugging shoulders> i have to admit i was never bothered by this behaviour. werner

BS Web and Pharo
by Tim Mackinnon Aug. 7, 2018

Aug. 7, 2018

Hey guys - when reading about the BS web (great article btw - https://pxlnv.com/blog/bullshit-web/ ) it reminded me about the constant pestering to sign up for the Pharo newsletter. Given I am signed up - how can I stop it always popping up? Itâs in the list of the BS web... so do we really need it to do this? At least it should be a cookie that if I have it it goes away, or better still - just put it as a menu entry and let people sign up if they like out stuff? Given our community fights the BS can't we lead better? Tim Sent from my iPhone

Pharo Launcher & Stored Settings
by Evan Donahue Aug. 7, 2018

Aug. 7, 2018

Is there a way to handle settings that should be different for every image when using Pharo Launcher? In particular, Settings > Software Configuraiton > Monticello > Default Local Repository & Local Cache Directory should be specific to the new image, but if I ever store settings for any reason, they get saved and incorrectly propagate to fresh images. Also, they are initialized wrong in the first place. How can I avoid this issue without manually adjusting these paths every time I make a new image? Thanks, Evan

Morph reacting to Window being closed
by Peter UhnÃ¡k Aug. 7, 2018

Aug. 7, 2018

Hi, how can a Morph react to its parent window being closed? E.g. Morph subclass: #MyMorph. MyMorph new openInWindow how can MyMorph cleanup itself on window close? I thought Morph>>delete would do the trick, but it is not being called. Thanks, Peter

Cargo & Future Proofing Releases
by Evan Donahue Aug. 7, 2018

Aug. 7, 2018

Hi, I will have a few general interest packages to release in the near future, for performance testing, contracts, and the like, and I'm wondering what the current story is for package release. I've heard some things about an upcoming "Cargo" package manager, so I'm wondering what the timeline on that is and whether I should be doing anything in anticipation of that, whether I should be putting things on the old Catalog, and just generally what the standard story is right now for releasing packages. Thanks, Evan

Pillar Book Tester
by Quentin DUCASSE (CI_2020) Aug. 5, 2018

Aug. 5, 2018

Hello everyone! I am currently in an internship within the RMoD team and would like to present my work. My internship subject was the following: âHow to test documents (books, slides) written in Pillar?â. Let me first introduce Pillar then what I managed to implement and what is left to do. -What is Pillar? Pillar is a markup syntax and associated tools to write and generate documentation, books, slide-based presentations or websites. Pillar syntax is similar to Markdownâs one but its emphasis is stressed on publishing to different formats/languages (Markdown, html, LateX, pdf). -What does it mean to âtest a bookâ? -- Display code within the book Pillar syntax allows you to write codeblocks, showing a part of code. The inside of a codeblock allows one to display any part of code you might want to. For example: [[[ YourClass >> yourMethod ^ âblaâ ]]] This codeblock presents a method definition, the other two possible codeblocks are the following: Class definition [[[ Object subclass: #YourClass instanceVariableNames: '' classVariableNames: '' package: YourPackage' ]]] Example [[[ 1+1 >>> 2 ]]] -- How to test it? The use of â>>>â and parameters in the codeblock will help us to test the code within it. The BookTester will turn examples into tests. Testing examples: [[[testcase=true 3+4 becomes self assert: (3+4) equals: 7 >>>7 ]]] Testing methodDefinitions and classDefinitions: Testing method or class definitions resumes is the same as testing if the compilation of the method does not raise any error. It can help make sure your book is up to date with the latest Pharo version. Those tests are done the same way as testing an example: stating methodDefinition=true or classDefinition=true as code block parameters will make them elible for tests. Now, we are adding more features to code block or Pillar to help book writers. -Additional Features In Pillar, several annotations can be used for different purposes like including columns/tables/citations/figures/linksâ¦ -- Loading code: loader ${loader:account=QDucasse|project=TestBook|tag=Chapter1}$ allows you to load the github project as it was in the commit tagged Chapter1. This will help you test every chapter of your code with its current progression and also allow you to test the objects you are defining in your book. - Executing Tests: run ${run:testClass=YourClassTest}$ runs the test defined in the class testClass. And of course this testClass can be Other annotations have been added to help you write your book: - Display a class definition: showClass: ${showClass:className=YourClass}$ displays a codeblock with the class definition within it This helps you quickly include a class definition you want to display in your book. Combined with the loader it means that the code can be the source of your book. - Display a method definition: showMethod: ${showMethod:className=YourClass|methodName=yourMethod}$ will display a codeblock with the method definition within it This helps you quickly include a method definition you want to display in your book. - Screenshot: ${showMethod:packageName=yourPackage|className=YourClass|methodName=yourMethod|caption|width|label}$ saves a screenshot of a Calypso browser open at the selected package, class and method and includes it in both your book (using the designated Pillar figure reference) and the figures subfolder in the pillar book folder (saved as PNG). -Future objectives One of the future improvements would be to make everyone able to write examples and test them in the comments of method definitions. It is already partially possible â3+4 >>> 7â will be highlighted differently and if printed will display â7->7â. However, an automation or UI improvement would be nice. I hope this gave you the will to write something you had in mind. Are there any books you want to try the tools on? Feel free to ask ! Quentin Ducasse
