Description

Miscelaneous list functions

copy_tuple_except/5	Copy every element of tuple TS to tuple TT ignoring the item at Ignore position.
group/2	Group elements in the `List` by element at position `Pos`.
sum/1	Add every positional element of each tuple in the list.
sum/2	Add every positional element of two tuples.
zip_record/2	Convert a record/tuple to a list of `{Name,Value}` pairs, where `Name` is a field name taken from the `Fields` list.

copy_tuple_except(Ignore, I, N, TS, TT) -> any()

Copy every element of tuple TS to tuple TT ignoring the item at Ignore position

group(Pos :: integer(), List :: [tuple()]) -> [{any(), tuple()}]

Group elements in the List by element at position Pos.

sum(ListOfTuples) -> any()

Add every positional element of each tuple in the list. E.g. sum([{1,2}, {3,4}, {5,6}]) -> {9,12}.

sum(Tuple1, Tuple2) -> any()

Add every positional element of two tuples. E.g. sum({1,2}, {3,4}) -> {3,6}.

zip_record(Fields :: list(), State :: tuple()) -> list()

Convert a record/tuple to a list of {Name,Value} pairs, where Name is a field name taken from the Fields list.
