trigger on setting a tag

[jkumeboshi]

I think that trigger from a specific set of tags would be useful, to avoid to OCR any loaded PDF.

I would like to set a flow triggered by "ocr" tag, so I could:

1. control which files are sent to OCR
2. OCR also any already loaded files

Hi @jkumeboshi and thanks for this nice suggestion. I did a quick test and indeed the workflow engine is now possible to trigger workflows based on the Tag assigned event (when we first developed this app, that event wasn't yet available).

So yes we're looking forward to implement this feature. Just to pin the use-case:

1. Create a new OCR workflow based on the event type Tag assigned with an arbitrary tag name
   

2. Tag the files you want to be processed with the matching tag used in step one by using the file details menu
   

Expected result: the file will be added to the OCR queue and will be processed the next time NC cron runs.

@jkumeboshi is that how you would like it to work?

@bahnwaerter FYI some technical todos:

• Allow the event name OCP\SystemTag\ISystemTagObjectMapper::assignTags with event type OCP\SystemTag\MapperEvent in https://github.com/R0Wi/workflow_ocr/blob/2bac1874cec319a4e9e884576f4fb2b513ae7fa3/lib/Operation.php#L126
• Check if its possible to retrieve the file details from this event in https://github.com/R0Wi/workflow_ocr/blob/2bac1874cec319a4e9e884576f4fb2b513ae7fa3/lib/Operation.php#L100
• Add some tests for this kind of event
• Add the use case to the docs

[jkumeboshi]

yes, the use case is exactly what I expect (indeed I already tried that exact use case, hoping it was already working :) )

Shouldn't be too hard to implement this. I'd really appreciate if you volunteer to test this if it's ready 👍

[jkumeboshi]

@R0Wi of course I can test it

@jkumeboshi @bahnwaerter a draft ist ready at https://github.com/R0Wi/workflow_ocr/suites/4422620243/artifacts/116982028. Would be nice if you could give me some feedback 👍

[jkumeboshi]

I did many test this morning and works perfectly for me.
I'll use that test version by now, waiting an update in the app store.

[R0Wi]

Thanks for your feedback @jkumeboshi. You can track the progress at #74. We're working on that feature so we try to push it to the appstore these days.

FYI this is now officially included in v1.23.0 (Nextcloud 23) and v1.22.3 (Nextcloud 22), see https://apps.nextcloud.com/apps/workflow_ocr. Thank you all for contribution ❤️
