Erlang code critique
- by dagda1
Hi,
I am trying to get my head round some basic erlang functionality and I could do with some comments on the following.
I have the following erlang code that takes a list of tuples and returns a list minus an element if a key is found:
delete(Key, Database) ->
remove(Database, Key, []).
remove([], Key, Acc) ->
Acc;
remove([H|T], Key, Acc) ->
if
element(1, H) /= Key ->
[H| remove(T, Key, Acc)];
true ->
remove(T, Key, Acc)
end.
Is this a good way of doing this?
The if statement seems incorrect.
Also is my use of the accumulator Acc making this tail recursive?
Cheers
Paul
