Quick learn for today, when you need to check the public functions from a specific module use the helper exports/1, here an example:
iex(1)> exports Enum
all?/1 all?/2 any?/1 any?/2
at/2 at/3 chunk/2 chunk/3
chunk/4 chunk_by/2 chunk_every/2 chunk_every/3
chunk_every/4 chunk_while/4 concat/1 concat/2
count/1 count/2 count_until/2 count_until/3
dedup/1 dedup_by/2 drop/2 drop_every/2
drop_while/2 each/2 empty?/1 fetch/2
fetch!/2 filter/2 filter_map/3 find/2
find/3 find_index/2 find_value/2 find_value/3
flat_map/2 flat_map_reduce/3 frequencies/1 frequencies_by/2
group_by/2 group_by/3 intersperse/2 into/2
into/3 join/1 join/2 map/2
map_every/3 map_intersperse/3 map_join/2 map_join/3
map_reduce/3 max/1 max/2 max/3
max_by/2 max_by/3 max_by/4 member?/2
min/1 min/2 min/3 min_by/2
min_by/3 min_by/4 min_max/1 min_max/2
min_max_by/2 min_max_by/3 min_max_by/4 partition/2
product/1 random/1 reduce/2 reduce/3
reduce_while/3 reject/2 reverse/1 reverse/2
reverse_slice/3 scan/2 scan/3 shuffle/1
slice/2 slice/3 slide/3 sort/1
sort/2 sort_by/2 sort_by/3 split/2
split_while/2 split_with/2 sum/1 take/2
take_every/2 take_random/2 take_while/2 to_list/1
uniq/1 uniq/2 uniq_by/2 unzip/1
with_index/1 with_index/2 zip/1 zip/2
zip_reduce/3 zip_reduce/4 zip_with/2 zip_with/3
Also works with Erlang modules:
iex(2)> exports :io
nl/1 columns/0 columns/1 rows/1
get_chars/2 get_chars/3 get_password/0 get_password/1
setopts/1 write/1 write/2 read/1
read/2 read/4 fwrite/1 fwrite/3
fread/2 fread/3 scan_erl_exprs/1 scan_erl_exprs/2
scan_erl_exprs/3 scan_erl_exprs/4 scan_erl_form/1 scan_erl_form/2
scan_erl_form/4 parse_erl_exprs/1 parse_erl_exprs/2 parse_erl_exprs/4
parse_erl_form/1 parse_erl_form/2 parse_erl_form/3 parse_erl_form/4
request/1 requests/1 requests/2 scan_erl_form/3
fwrite/2 getopts/1 nl/0 rows/0
put_chars/2 setopts/2 get_line/2 parse_erl_exprs/3
read/3 request/2 getopts/0 get_line/1
put_chars/1 format/1 format/2 format/3
printable_range/0
