Hello, I work on a project where I have multiple colls. I want to combine all the lists in there in one single coll. Is there a way to do that directly without unpacking and repacking everything?

In order to be more clear, let's say I have two colls, with the first one being:

I would like the final coll to be one list from 0-199.

Please keep in mind I don't want to unpack everything ( with uzi for instance) cause my lists are very long and I find that it is problematic for the cpu to use colls with such long lists.That's why I broke my huge list into sublists/subcolls in the first place

I don't think there is a non-explicit way but you might be able to do it using javascript (but it may be even less efficient than using an explicit uzi solution); it may be better to approach the problem with the dict system instead of coll ...

Thanks for the answer, I wasn't aware of "dict" as I still prefer to use Max 5. However do you think that this approach is going to be more cpu friendly than coll? I will try to give a shot with dict later today!

depends how the dict data structure is implemented. I know that coll uses a linked list which is slower to access than other possible data structures, such as a hash table, which dict probably uses...

here is a benchmark patch with some interesting results (for my computer anyway) --

it seems dict is generally about 10 - 20 times faster than coll, *except* if you use the dump message, where coll is at least 20 times faster than dict...!

So you may use [dump] for combining colls.

once you wire up the outputs, it turns out there's not that much difference between dumping 2 colls and concatenating two dicts:

dict is a little faster (10% better) with this simple example...

Hey thanks for all the answers and the interesting patches. I feel that although dict is much faster on accessing data, Max is overall slow for this kind of job!
