以前作ったものをgemにまとめました。実行中のオブジェクトのクラス階層や、メソッド一覧を簡単に調べることが出来ます。
require 'rubygems' require 'rubywho' # Hello. 1.who? "string".who? String.who? [1, 2, 3].who? # Method filtering. require 'active_record' ActiveRecord::Base.who?(/sql/)
実行結果
Fixnumのクラス階層

Stringのクラス階層

クラスを引数に取るとシングルトンメソッドを表示
== String.who? == String(Class) | yaml_new, yaml_tag_subclasses? v------------------------------------------------------------------------------- . . Kernel(Module) . .
配列
== [1, 2, 3].who? == Array# | assoc, at, choice, clear, collect, collect!, combination, compact, compact! | concat, count, cycle, delete, delete_at, delete_if, drop, drop_while, each . .
ライブラリもOK
== ActiveRecord::Base.who? == ActiveRecord::Base(Class) | count_by_sql, find_by_sql, sanitize_sql, sanitize_sql_array | sanitize_sql_for_assignment, sanitize_sql_for_conditions, sanitize_sql_hash | sanitize_sql_hash_for_assignment, sanitize_sql_hash_for_conditions v------------------------------------------------------------------------------- ActiveRecord::Aggregations(Module) v------------------------------------------------------------------------------- ActiveRecord::Transactions(Module) . .

特殊機能
moroさんの改良版に影響を受けtapスタイルになってます。他にも色々な機能を追加しました。
require 'rubygems' require 'rubywho' # フィルタリング 1.who?("to_") # クラス階層の深さを指定 1.who?(nil, 3) # ショートカット 1.who1? puts "== who0? display 1-line. ==" 1.who0? # 強制的にインスタンスメソッドを表示 1.who_instance? Fixnum.who_i? # 強制的にシングルトンメソッドを表示 1.who_singleton? Fixnum.who_s? # メソッドチェインの間に挟み込む puts "== who0? method chain. ==" [1, "cat", "cat", 2, "cat", 3].who0?.select{|i| i == 'cat'}.who0?.count.who0?
