Extension no longer has access to folders from `pickFolder`

[n8gray]

I’m trying to build a shortcut that will do some git operations in another app’s sandbox.

• I’ve used pickFolder to create a bookmark to that folder called LogSeq.
• I’m running a script to cd to that folder and do the work
• The script works when run in the full app, but doesn’t work in the extension
• I’ve tried using the full path to the folder instead of the bookmark. Neither way works
• I believe this used to work? I’m basing this belief off comments from people in the LogSeq community who used this workflow in the past, but I’ve never personally used it before.

Thanks!

From Apple's point of view, the App and the extension are two different apps, with different permissions. The extension does not have access to the same folders as the app (and reciprocally). They have a few bookmarks in common (~iCloud and ~shortcuts/~group), but that's it.

Thanks for the reply! The "Working Copy" app makes this work somehow. You can make shortcuts that operate on a repo in the LogSeq sandbox without bringing Working Copy to the foreground. I suspect there's a way to configure your entitlements so that the extension and the app share these acquired permissions. I'll do some research this weekend and see if I can find the info.

Thank you for pointing out that it was possible; I may have found out how to do it. I'm implementing it.

Awesome, great to hear it.

Hello again! Just curious - did you found a way to make this work?

[holzschu]

Not for now. I'm back to "I have no idea how this could work".

How Working Copy does it?

@holzschu do you have any pointers to what you thought might be the 'trick'? I'd like to do some digging in the Apple documentation to see what might be possible

[holzschu]

Apple documentation explicitly says that this is impossible. I have no idea how Anders Borum does it with WorkingCopy, and I think the only way to know would be to ask him directly.

@holzschu tnx - I first had to figure out what is exactly the Shortcut Item where this is used, but yes it indeed works in Working Copy (Pro Version):

1. Create a new repository in Working Copy with "Link to external directory" and e.g. select On iPhone > Obsidian > Notes (which is my repository name in Obsidian) as the folder
2. Create a Shortcut with an action "Get Repository Files", select the Repository Created and select the path to a test file e.g. /Test.md which is in my On iPhone > Obsidian > Notes directory
3. Switch to Obsidian and make a test edit in the Test.md file
4. Switch back to Shortcuts and run the Shortcut: it indeed shows the updated content!

So somehow Andreas is able to make this work (which is nifty!) Let's see if we can ask him if he would be able to shed some light on he is able to get this to work! https://mastodon.nl/@mdbraber/112433500468179009 @palmin

Working Copy will run most of its Shortcuts actions from the main binary (while staying in the background) as the memory limits are a little relaxed compared to an intent extension. A side effect is that security scoped bookmarks made by the main app work.

I'm not 100% sure this is the whole story but I would try this as a first thing.

[mdbraber]

Thanks for thinking along @palmin! I have to get a bit acquainted with the code (and Intents API), but would this mean that NSExtensionPointIdentifier would not be com.apple.intents-service or NSExtensionPrincipalClass has to be changed?

This video describes how to handle intents in the main app:

[holzschu]

Thank you for the explanation, @palmin! If the Shortcuts actions are run from the main app, not the extension, that explains everything.

[mdbraber]

With my limited knowledge of building iOS apps, this does seem rather possible as most of the Intent logic is already there. It seems that handling intents can be simplified as we don't need to repeat code as is now done in e.g. IntentHandler.

@holzschu what do you think? Would it be feasible to change from running apps in the extension to running from the main app?
