Storing long strings in PIO objects

[Jayme McColgan]

I'm looking for a way to store basically a log in one of my PIO objects. what is the max length of characters i can have in a hidden parameter? is there a better place to store it that would be linked to the PIO instance no matter what user/computer has the drawing open.

The last time I tried it was 32767, something to do with Int types or LongInt, I can't remember.

I've in the past used a splitter command and had 3 params set aside for storing data eg (storeParam1, storeParam2).

 

code below is an example of how it would go

# Split every_length x characters
def value_splitter(listparams:list, value_to_store):
    """
    listparams is List of record/plugin | field/parameter names
    """
    val_str = str(value_to_store)
    max_char_length = 32767
    val_params = [val_str[i: i + max_char_length] for i in range(0, len(val_str), max_char_length)]
    
    if len(val_params) <= len(listparams):
        for i, x in enumerate(listparams):
            vs.SetRField(plugin_handle, record, x, val_params[i])
    
    else:
        raise ValueError("Number of parameters too few for splitter")

 

 

A while back, VW introduced the use of ObjectUUIDs. You could try storing these in a json file together with the rest of the other data you're wanting to store.

ill have to give this a try. ideally i want to store it in a json format in the field. i think i could be fine with 32767 characters. i could also have it delete older data as it fills up. ill report back with what i come up with.
