How to contribute to Pharo Launcher?
by Tim Mackinnon June 19, 2018

June 19, 2018

Is PharoLauncher using git - there is a note saying the StHub repo is about to be moved? I ask as I wanted to contribute a simple change that shows the modified date of the images and lets you sort by that (I sometimes forget which was the latest image I was using and have a few old ones kicking around).

Re: [Pharo-users] How to fix the Pharo launcher Windows installation! (WAS: Windows installation broken?)
by Vincent.Blondeau＠lamresearch.com June 18, 2018

June 18, 2018

Hi all, Indeed, the Windows environment is not the one where Pharo is working the best. Last week, I tried to install it on one of my coworker desktop and there was some issues that was solvable with some workarounds, it is temporary and the windows support will be improved soon: I'm currently working on it, especially on making the Pharo launcher in a read only mode. This way, no administrative privileges will be required to run the launcher. In the meantime, to make the launcher working under Windows: 1. Run with administrative privileges 2. Uncheck: [cid:image001.png@01D406FB.17336870] If you are in a mood to help and contribute to this project (I hope you are!), please report the issues there: https://github.com/pharo-project/pharo-launcher/issues and feel free to suggest some fixes to them :) And please, keep this thread related to Pharo...

This is what concerns me. I don't care that there are workarounds (undocumented or hard to find). I care that Windows is a most popular development platform. I care that newcomers to Pharo easily find what they need to get started. I care about Pharo's reputation. The last thing Pharo needs is a black eye.

Nice Pharo teaser in English?
by Andrei Stebakov June 18, 2018

June 18, 2018

I remember there used to be a nice Pharo teaser video at the top of pharo.org which had some catchy images for data visualization etc. Now all I can see is this link https://www.dailymotion.com/video/x3qedvo and it's in French. Could someone point me to the old teaser I am referring to? Thanks! Andrei

Windows installation broken?
by horrido June 18, 2018

June 18, 2018

Someone told me that they had difficulties installing Pharo under Windows. So I had to see for myself. I booted my Mac mini into Windows 7 Ultimate (using Boot Camp), downloaded and installed Pharo Launcher. That person was indeed correct. The Windows version of Pharo is badly broken. I created images for Pharo 5.0, 6.1, and 7.0, and all three refused to open (presumably, they just crash). Am I missing something? What am I doing wrong? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Confusion for Pharo MOOC
by horrido June 18, 2018

June 18, 2018

I just discovered a huge source of confusion for the Pharo MOOC. There are two different websites that seem disconnected. One presents information on the next Pharo MOOC session, and the other doesn't. https://www.fun-mooc.fr/courses/course-v1:inria+41010+session03/about http://mooc.pharo.org If you're in the know, this isn't a problem, but if you're a newcomer to Pharo, it's a BIG problem. How do I know? Because I was totally confused! -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Why doesn't Iceberg checkin other assets (scripts) but does check them out?
by Tim Mackinnon June 18, 2018

June 18, 2018

Hi - my second attempt at using Pharo with Git has proven very satisfying (I saw the potential in phase 1, but it was often difficult to understand what was happening and the workflow to use). One thing that has come up a few times for me however - and its something that using git nicely highlights, there are many non-smalltalk assets in my project that donât need to live in the image (like Seaside FileLibraries were trying to do) but do need to be versioned and be part of my project. Common examples are server config files, images and even the playground history files that are useful to pull up when on another computer. It seems that while Iceberg does check out a full project, if I change any of the files outside of the src directory (like edit a .txt file using the crude Pharo file editor), those changes donât get committed when I do a checkin? Is this on purpose? It makes the workflow a bit trickier to do an atomic commit of a piece of work - and Iâm not clear whether this is a conscious thing, or an MVP thing (and it will come later). As mentioned above, I was also thinking it would be nice if I could checkin some of the play-xxxx/*.sh files to essentially keep some of that history synced between environments (or team members?). It strikes me that this is the kind of thing that git integration should bring to us? I can overlay my copy of IntelliJ on top of my local iceberg directory and then use it for checkins - but then I still have the atomic problem, as its only when I commit that tonel files are written out onto the file system for me to checkin along with any other assets Iâve changed. Does anyone else have a good workflow for this? What do you guys do? Tim

NeoJSON extension - easier list handling with NeoJSONPropertyMapping
by Ben Coman June 17, 2018

June 17, 2018

hi Sven, With NeoJSON I have found several times in handling lists that I need to indirect through #for:customDo: like this...... reader for: ExercismProblems do: [ :mapping | self halt. (mapper mapInstVar: #problems) valueSchema: #ArrayOfProblems ]. reader for: #ArrayOfProblems customDo: [ :mapping | mapper listOfElementSchema: ExercismProblem ]. when I'd really like to be simpler and more concise like this... reader for: ExercismProblems do: [ :mapping | (mapping mapInstVar: #problems) listOfType: Array withElementSchema: ExercismProblem ]. so I'm seeking your feedback on the following hack which facilitates that. (and if I missed something that already makes it simpler) ---------------------------- Object subclass: #NeoJSONPropertyMapping instanceVariableNames: 'propertyName valueSchema getter setter collectionClass' "Added collectionClass" NeoJSONPropertyMapping >> listOfType: aCollectionClass withElementSchema: elementSchema collectionClass := aCollectionClass. valueSchema := elementSchema NeoJSONPropertyMapping >> readObject: anObject from: jsonReader | value | value := collectionClass ifNil: [jsonReader nextAs: valueSchema] "nil by default retains the original behaviour" ifNotNil: [jsonReader nextList: collectionClass of: valueSchema ]. setter value: anObject value: value NeoJSONReader >> nextList: nextListClass of: schema "copied from #nextAs" "Secondary interface to parse JSON. Return a list of objects, each element according to schema." ^ nextListClass streamContents: [ :stream | self parseListDo: [ stream nextPut: (self nextAs: schema) ] ] ---------------------------- Sample data is shown at: https://github.com/bencoman/pharogui-exercism/blob/master/README.md with the following code to access it. Object subclass: #ExercismAPI instanceVariableNames: 'client rawResponse jsonResponse success message result' classVariableNames: 'ApiKey' package: 'Exercism' ExercismAPI class >> configureApiKey: key ApiKey := key. ExercismAPI >> track: trackIdString self path: 'v2/exercises/' , trackIdString. ExercismAPI >> fetchTrack: trackIdString |znclient response| ApiKey ifNil: [ self error: 'ApiKey not configured. See class-side ExcercismAPI' ]. znclient := ZnClient new https; enforceHttpSuccess: true; accept: ZnMimeType applicationJson; host: 'x.exercism.io' . znclient path: 'v2/exercises/' , trackIdString. znclient queryAt: 'key' put: ApiKey. ^ [ response := znclient get ] on: ZnHttpUnsuccessful do: [ :exception | Transcript crShow: exception ] fetchJsonTrack: trackIdString | reader | reader := NeoJSONReader on: (self fetchTrack: trackIdString) readStream. reader for: ExercismProblems do: [ :mapper | (mapper mapInstVar: #problems) listOfType: Array andElementSchema: ExercismProblem ]. ^ reader nextAs: ExercismProblems In Playground... ExercismAPI configureApiKey: 'ec60c50cb50d4ffaa97903d5ebb3d5ff'. (ExercismAPI new fetchJsonTrack: 'go') inspect I'll reset the apikey shortly. You can get a new one from http://exercism.io/account/key. cheers -ben
