Per (https://github.com/exercism/meta/issues/91) it looks like the syntax highlighter is "prism" (https://prismjs.com/) I added ".st" for Pharo... ( https://github.com/exercism/meta/issues/90#issuecomment-399412215) It briefly crossed my mind to wonder if using ".st" for both traditional fileout format and tonel format might cause complications, but that might be jumping at shadows.

Hi Ben - it looks completely do-able. Just submitted my hello world for python - and it wasnât anything particularly special. I thought your suggestion of using Tonel is perfect - Iâm just not sure how well the exercism site will render tonel format (ideally with correct colour coding). Iâve noticed there are lots of Textmate themes for Smalltalk floating around (and indeed I took one and put it on my iPad for a text app whoâs name Iâve forgotten and it seemed to render tonal fine). So if exercism uses that - then it really shouldnât be a ton of work to make the submit/pull calls like you suggested?

I haven't put any thought into exercises, but have been thinking about infrastructure. Here is some discussion about making a code exporter to be able to use the command line tool to interact with the server. https://github.com/exercism/pharo/issues/6#issuecomment-398346884 I've been looking at how the command line tool communicates with the server to determine how hard it would be too hard to write a Pharo direct interface to their server.

Re: [Pharo-users] Tonel Fileout

by Tim Mackinnon

Just as a followup to this - Bens suggestion can be slightly simplified (and less dependent on implementation details) as: tonelStream := ââ¦pathâ¦./src/Polymorph-Widgets-Rules/IconShortcutRule.class.st' asFileReference readStream. parser := (TonelParser on: tonelStream). parser document do: [ :item | item load ]. If you want to load an entire directory you can use a reader (but sadly the reader doesnât let you load only one file) tonelLocator := ââ¦pathâ¦./src/Polymorph-Widgets-Rules/IconShortcutRule.class.st' asFileReference. (TonelReader on: tonelLocator fileName: tonelLocator path parent pathString ) loadDefinitions.

Re: [Pharo-users] ApplicationSecurity Questions

by Sean DeNigris

Moved from Pharo-Devâ¦ > Please let me know how it is going Iâm at the point where I seem to have a basic understanding of the library and Iâm ready to integrate into an app Iâm writing. Here are a few questions, which I put into an issue [1] to fold back into the docs when the conversation is âcomplete" Repository Access The following code seems problematic: ASRepository class>>#repositoryNamed: aString â¦ ^ self allInstances detect: â¦ Isn't it possible that a rogue instance could be returned instead of the one that's part of the model? For example, some persistence libraries like SimpleImagePersistence replace segments of the object graph and might have the old and new copy present during a load. Where do Check Points Live? In the IGEVET app, it seems that each session hasA checkPoint which hasA repository. Is this the way youâd recommend using AS in a real app? It seems that the default repository implementation loads the whole user DB from disk via Fuel, so wouldnât that happen for each session?! 1. https://github.com/hernanmd/ApplicationSecurity/issues/3 <https://github.com/hernanmd/ApplicationSecurity/issues/3>

What's the status of Pharo exercism?

by Tim Mackinnon

Presumably someone is working on Pharo Exercism (did I notice Ben or Hilaire asking about the tonel format for it?) Is it possible for someone to put a comment in the repo for it - so we can coordinate effort? Iâm assuming that someone can at least get hello world working as an example? It would also be handy if someone who understands how it works, can give a quick explanation here - as I would offer to suggest it as something for the next UK Smalltalk gathering next month. Iâm assuming the cli submits files to some travis runner and you get results back - and we just have to fill something in that will interpret those files and launch a command line pharo to get the results (presumably handling walkbacks in a way that the results get fed back). And then Iâm guess we have a pharo add-in that would let you do this from the image some way too? Tim
