During an iex session, I can do a little introspection on modules using
either the
__info__/1
function or Erlang's
module_info/0
function. In particular, I can pass :functions to either one to get a list
of the functions for that module.
This is what __info__/1 looks like for the functions of the List
module:
> List.__info__(:functions)
[delete: 2, delete_at: 2, duplicate: 2, first: 1,
flatten: 1, flatten: 2, foldl: 3, foldr: 3, insert_at: 3,
keydelete: 3, keyfind: 3, keyfind: 4, keymember?: 3,
keyreplace: 4, keysort: 2, keystore: 4, keytake: 3,
last: 1, replace_at: 3, to_atom: 1, to_existing_atom: 1,
to_float: 1, to_integer: 1, to_integer: 2, to_string: 1,
to_tuple: 1, update_at: 3, wrap: 1, zip: 1]
