Can you extract all tags names down to their atomic form?

[TheWicklowWolf]

For example, if you have a user-defined data type (UDT) tag consisting of a Real and a DINT... How can you obtain a tag list containing all elements?

I tried get_tag_list() but that returns:

complexTag

Whereas I'm looking to extract in down to:

complexTag.myUDT.myDint
complexTag.myUDT.myReal

get_tag_list() returns a dictionary of all the top-level tags, so that's why you're not seeing all of the sub-tags. You can write a small function to recursively walk all of the structs to get a flattened list:

from pycomm3 import LogixDriver
from rich import print


def flatten_tags(tags):
    def flatten_struct(struct):
        for attr in struct['attributes']:
            yield attr
            if struct['internal_tags'][attr]['tag_type'] == 'struct':
                yield from (f'{attr}.{x}' for x in flatten_struct(struct['internal_tags'][attr]['data_type']))
                
    
    for tag, _def in tags.items():
        yield tag
        if _def['tag_type'] == 'struct':
            yield from (f'{tag}.{attr}' for attr in flatten_struct(_def['data_type']))
        
    
    
with LogixDriver('...') as plc:
    print(plc.tags)  # same as get_tag_list, set automatically when connection is opened
    print(list(flatten_tags(plc.tags)))

Just what I was looking for, thank you!
By the way, the library is absolutely fantastic! Great Work
