How can I iterate through this structures in the array? I mean want to do somthing like:

for person in ``peaople.items()``
  echo ``person.name``
  echo ``person.age``
done

[kristopolous]

I'm sorry, not trying to be mean, but that's not valid syntax. You are doing { [] } ... which is invalid, hashes have to have keys. I don't have elegant ways of dealing with syntax issues. Maybe we can figure something out.

[kristopolous]

As far as the original question ... even if you did the syntax fix we still have a problem ... because person gets expanded ... If you really want something, I think ${!person}_name will work, but that's not discoverable at all. Man, what a silly project this is ... I'll see what I can do about it. Thanks.

Of course you're right the syntax wasn't valid. I fixed it:

    echo ${!person}                                                                                                                                                                            
done 

The main problem why it doesn't work is that each element of structure in array is treated as element of array. Output:

23
Alice
43
Bob
13
Harry

I don't call it big bug, just was curious what's TickTick is capable of. :) Maybe I'll think how to add this feature.

well this was a project to amuse my peers in the extreme shell scripting world ... not really to facilitate awesomeness. Let me satisfy a separate pull request and then address this.

I ran into this very same issue.. I have

{"id":"519f1f8c47c12c347900290a","name":"Test","desc":"","lists":[{"id":"519f1f8c47c12c347900290b","name":"To Do"},{"id":"519f1f8c47c12c347900290c","name":"Doing"},{"id":"519f1f8c47c12c347900290d","name":"Done"}]}

and want to do something like:

for list in ``lists.items()``; do
  echo "Item: ${!list}_name [${!list}_id]"
done

Will probably work around it with looping over the indexes instead based on lists.length()..
