for my $author ( @$authors ){
   $reputation_sum += int( $author->{reputation} / 1000_000_000 );

get_discussions_by_xxxxxx

all those methods will sort the results differently and accept one query parameter with the values:

{
   tag   => 'tagtosearch',   # optional
   limit => 1,               # max 100
   filter_tags => [],        # tags to filter out
   select_authors => [],     # only those authors
   truncate_body  => 0       # the number of bytes of the post body to return, 0 for all
   start_author   => ''      # used together with the start_permlink gor pagination
   start_permlink => ''      #
   parent_author  => ''      #
   parent_permlink => ''     #
}

so one example on how to get 200 discussions would be

my $discussions = $steem->get_discussions_by_created({
      limit => 100,
      truncate_body => 1,
});

my $discussion = $discussions[-1];

push @$discussions, $steem->get_discussions_by_created({
      limit => 100,
      truncate_body => 1,
      start_author   => $discussion->{author},
      start_permlink => $discussion->{permlink},
});

vote

this requires you to initialize the module with your private posting key like this:

my $steem = Steemit::WsClient->new(
   posting_key => 'copy this one from the steemit site',

);

$steem->vote($discussion,$weight)

weight is optional default is 10000 wich equals to 100%

comment

this requires you to initialize the module with your private posting key like this:

my $steem = Steemit::WsClient->new(
   posting_key => 'copy this one from the steemit site',

);

$steem->comment(
      "parent_author"   => $parent_author,
      "parent_permlink" => $parent_permlink,
      "author"          => $author,
      "permlink"        => $permlink,
      "title"           => $title,
      "body"            => $body,
      "json_metadata"   => $json_metadata,
)

you need at least a permlink and body fill the parent parameters to comment on an existing post json metadata can be already a json string or a perl hash

delete_comment

$steem->delete_comment(
   author => $author,
   permlink => $permlink
)

you need the permlink author will be filled with the user of your posting key if missing
