keyed value types with pseudo-dict - Methods Library "key_vals"
a set of primitive single-type key/value items, and pseudo-dictionaries
The dictionaries are single arrays of items, each item has a key and value.
The library is 100% methods. add, remove, get and set items by key.
It provides methods to get all the keys, values or items in the dict as arrays.
For those familiar with python, it's similar, but typified.. and the brackets are round.
example syntax.. using floats, the same functions exist for Int, Bool and String
new float_item
new (‘demo’, 1.0 )
set the key of a float_item
float_item.key (‘demo’)
get the key of a float_item
float_item.key ()
set the value of a float_item
float_item.val (1.5)
get the value of a float_item
float_item.val ()
get the number of items in a dict
float_dict.count ()
set an item to a dict by key ( add / update)
float_dict.set ( ‘demo’, 2.0 )
remove an item from a dict by key (changes index, but this is about keys, not ids)
float_dict.remove ( ‘demo’ )
get an item from a dict array
array.get (1 )
get an item from a dict by key
float_dict.get ( ‘demo’ )
get an item from a dict by id (remember, ids change if removed by key) mainlyy an internal function
float_dict.get ( 1)
return all keys as string
float_dict.get_keys()
return all values as float
float_dict.get_values()
return all items as float
float_dict.get_items()
create a new float dict in the multi dict and return the index of it
multi_dict.add_float_dict()
get the float dict at index 0 from the multi dict
multi_dict.get_float_dict( 0)
set an item in a float dict in a multi dict
multi_dict.set_float( ‘demo’, 2.0 )
get an item from a float dict in a multi dict
multi_dict.get_float( ‘demo’ )

Datastorage
Data structure map[string, float]The script shows a workaround for map in pine-script via drawings.
There are few restrictions with them:
1. The size of the map cannot be more that amount of allowed drawings (about 40 by now)
2. Because the map shares the space of drawings throughout the whole script, using drawings with the map must be careful, with handly creating and removing of each drawing, because otherwise pine's garbage collector might break the stack. I'd recommend not using more drawings with the map.
3. setters and getters must be called on every bar, because of implementation of functions in pine there are inner serieses, which must be updated on every bar. So wherever you have a setter or getter in the code - it must be called on every bar. But if it's just an update, then you should pass 'false' as a param of the funtion.
The script shows a way to work with the map: filling it with some tickers and values for each of it and then plot the value if the symbol on the chart equals to one of the tickers in the map.
And there are some examples of updating of the value and removing of the item from the map.
