Running an executable with JSON output

[jandamm]

Hi,

I want to run a executable which returns JSON and use this JSON data in Hazel (5).
It's easy to run the executable in the "Passes shell script" part but I cannot use the returned data since Hazel just uses the exit code.
I tried running an executable in JS but every snippet I found on the internet didn't work.

Has someone achieved something comparable and could give me a hint?

Cheers
Jan

What do you want Hazel to do with the JSON?

I would want to use the values in the JSON as variables in Hazel.

I got it somewhat working with this snippet for AppleScript but it would be easier to handle JSON:

Code: Select all

set filesLists to do shell script "ls"
set AppleScript's text item delimiters to return
set theArray to every text item of filesLists
return {hazelPassesScript:true, hazelOutputAttributes:theArray}


In the settings for this step I then set output variables to grab the values.

("ls" is just for testing)


My main issue is that I've currently using many rules to sort my pdfs into DEVONthink.
The rules are written in JS and are very duplicated since they basically do a regex and return a new filename if matched.
I've started to write a kind of matcher in Swift which I know much better than JS and wanted to return a JSON which can be interpreted by Hazel and then use Hazel to rename/move etc based on the returned values.
I've thought about using just the Swift matcher but I'd prefer using Hazel for filesystem mutations since it is better tested and has error messages when something failed.
