CHANGELOG

leaderboard 2.5.0 (2012-10-12)

  • Added members_from_rank_range and members_from_rank_range_in methods to be able to retrieve members from a leaderboard in a given rank range.

leaderboard 2.4.0 (2012-07-30)

  • Added all_leaders and all_leaders_from methods to retrieve all members from a leaderboard. You may also use the aliases all_members or all_members_from.

leaderboard 2.3.0 (2012-07-09)

  • Added expire_leaderboard(seconds) to expire the leaderboard in a set number of seconds.
  • Added expire_leaderboard_at(timestamp) to expire the leaderboard at a specific UNIX timestamp.
  • Added optional page_size parameter to the total_pages method.

leaderboard 2.2.1 (2012-06-18)

  • Fix for #17 - Leaderboard not compatible with redis 2.1.1. Redis' zrangebyscore and zrevrangebyscore methods do not return scores by default. No need to pass the option in the initial call.

leaderboard 2.2.0 (2012-06-18)

  • Added members_from_score_range and members_from_score_range_in methods. These will retrieve members from the leaderboard that fall within a given score range.
  • Add member_at and member_at_in methods. These will retrieve a given member from the leaderboard at the specified position.
  • members and members_in are now aliases for the leaders and leaders_in methods.

leaderboard 2.1.0 (2012-06-11)

  • Added ability to store optional member data alongside the leaderboard data.
  • :with_member_data is now a valid request option when retrieving leader data.

leaderboard 2.0.6 (2012-04-26)

  • Added accessor for reverse option so that you can set reverse after creating a leaderboard to see results in either highest-to-lowest or lowest-to-highest order.

leaderboard 2.0.5 (2012-03-14)

  • Added rank_members(members_and_scores) and rank_members_in(leaderboard_name, members_and_scores) allowing you to pass in some variable number of member_name, score and so on or an actual array of those data items. Use this method to do bulk insert of data, but be mindful of the amount of data you are inserting since a single transaction can get quite large.

leaderboard 2.0.4 (2012-02-29)

  • Added page_for(member, page_size = DEFAULT_PAGE_SIZE) and page_for_in(leaderboard_name, member, page_size = DEFAULT_PAGE_SIZE) calls to allow you to determine the page where a member falls in the leaderboard

leaderboard 2.0.3 (2012-02-22)

  • Added :reverse => false to Leaderboard::DEFAULT_OPTIONS to support leaderboards sorted from lowest to highest score instead of highest to lowest score. (Thanks @siuying)

leaderboard 2.0.2 (2012-02-03)

  • Fix for checking to see if a member actually exists in the leaderboard for the around_me calls
  • Return appropriate nil in data returned for calls such as percentile_for and ranked_in_list for non-existent members

leaderboard 2.0.1 (2011-11-07)

  • Allow for only single options to be passed to leaders, around_me and ranked_in_list methods - #4
  • Added percentile_for(member) and percentile_for_in(leaderboard_name, member) methods to calculate percentile for a given member

leaderboard 2.0.0 (2011-08-05)

  • Change add_member to rank_member - #3
  • Added delete_leaderboard and delete_leaderboard_named - #2
  • Ability to pass in an existing Redis connection in initializer - #1
  • Added transaction support for score_and_rank_for, leaders, around_me and ranked_in_list
  • Updated initializer to take a leaderboard name, options hash and redis_options hash
  • Simplified leaders, around_me and ranked_in_list to use an options hash with defaults for the previously individual parameters

leaderboard 1.0.6 (unreleased)

  • Added disconnect method
  • Check for invalid page size when changing

leaderboard 1.0.5 (2011-05-04)

  • Updated Rakefile to run tests under ruby 1.8.7 and ruby 1.9.2
  • Added page_size parameter to total_pages_in to allow for checking what if values in that scenario
  • Added page_size parameter to leaders and around_me calls

leaderboard 1.0.4 (2011-04-26)

  • Minor bug fix

leaderboard 1.0.3 (2011-04-26)

  • Fixing issue using total_pages in leaderboard_in call
  • Internal massage_leader_data method will now respect with_scores

leaderboard 1.0.2 (2011-02-25)

  • Adding XXX_to, XXX_for, XXX_in and XXX_from methods that will allow you to set the leaderboard name to interact with outside of creating a new object
  • Added merge_leaderboards(destination, keys, options = {:aggregate => :min}) method to merge leaderboards given by keys with this leaderboard into destination
  • Added intersect_leaderboards(destination, keys, options = {:aggregate => :min}) method to intersect leaderboards given by keys with this leaderboard into destination

leaderboard 1.0.1 (2011-02-16)

  • redis_options can be passed in the initializer to pass options for the connection to Redis
  • page_size is now settable outside of the initializer
  • check_member?(member): Check to see whether member is in the leaderboard
  • score_and_rank_for(member, use_zero_index_for_rank = false): Retrieve the score and rank for a member in a single call
  • remove_members_in_score_range(min_score, max_score): Remove members from the leaderboard within a score range
