Re: [PD] Further questions on struct and the external api
I’m discovering the superb world of struct (with the 3 recommended tutorials, all of which very biased towards the graphic angle at least there is a visible reward for all the effort it takes to work with data-s I understand the argument, but for me I read it was ‘for graphics’ - it was limiting until I understood it was not just for that. it was just a joke. but yes, most of the patching around is used for graphic display/interaction. what you mean with dummy? [append] needs at least one float to be declared That is what I mean, in this case I just need key -> float array, neither of them would be able to trigger a creation of a new item. This is why [text] is my new friend, although it won’t help with nested lists and arbitrary dictionary style structures. I’ll find a way. I just tried to store and retrieve a pointer from [text] , it didn't work. But it does work with [list]. Maybe there is some smart hack that allows for (pointer) to be correctly read from [text]. if you're into consoles full or red letters. :D I’m trying to behave so the 2 proposals you put are great. I guess so far no one predicted that a scalar could have no variables at all. I am aware I’m bending the concept of struct. It was not meant to be a dictionary, especially not with nested ones. that indicates the principle could be improved. such like it's not possible to append a scalar with a symbol directly, there are still things to improve. if a struct template doesn't need a float, why force it to have one? the question I now have is for people developing externals Is this list the right place for that question? I would like to be able to read and write [text] and [struct] declared in the patch within my externals but I don’t know if that is possible in the API. probably the dev list might be more helpful, although they also are here. ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list

Re: [PD] Further questions on struct and the external api
I’m discovering the superb world of struct (with the 3 recommended tutorials, all of which very biased towards the graphic angle at least there is a visible reward for all the effort it takes to work with data-s but I found ways around) and my new favourite friend is [text] for that reason :) 2 questions: - in the attached patch, I needed to create a dummy entry to my ‘test-item’ struct to be able to dynamically add entries infusing [append] - do I understand right? what you mean with dummy? [append] needs at least one float to be declared, if that's what you mean (unless someone implements a bang method to add a scalar without variables). the "key" variable can be removed from the template, if you wish. But the scalar created isn't a dummy, but the array itself. Btw you can use [append test-item] with no further arguments. But there will be an error message "pd-test-item.: no such field" every time it receives an input, although it does create the scalar. You can even remove all variables and leave only [struct test-item array value float], if you're into consoles full or red letters. I guess so far no one predicted that a scalar could have no variables at all. - it seems that I would be able to find workarounds the fact we cannot search my dataset by making an entry that would hold my keys at the top but that is cumbersome so I’m now making friends with the fantastic [text] object… the question I now have is for people developing externals: is it possible to access and write to struct and/or arrays from an external developed through the API? I didn’t find examples doing so nor any reference to text_buf in the API so I wonder if anyone has any pointers on that. Worse case I can use a message to dump a list and then [text fromlist] but that would be limited by the maxlength of the said list which was a problem in Max (hence us going the extra mile of supporting native dicts there) Thanks all for your help. p ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list ___ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list
