RubyMine IDE中包的Ruby方法下拉列表？

Question

通常，在导入包并输入其名称但不在RubyMine中后，通过按Tab键来显示IDE中的下拉列表。我有Vim模拟。我打开了交互式红宝石外壳irb，但无法使自动完成适用于软件包的方法。

自动完成在RubyMine中如何工作以及如何列出软件包的方法（如OAuth）？

Answer 1

的RubyMine的自动完成作品大多通过完成整个项目使用的名称和关键字，请参阅here关于如何工作的一些细节。还有一个this问题可能会提供一些清晰的说明RubyMine中的完成工作方式。

至于关于列出程序包中的可用方法（真的在任何对象中）的问题。您可以使用方法.methods来获取对象响应的一组方法。 由于ruby的动态性和可能性实现method_missing，列表中可能不包含所有可能的方法。

这里有一个例子

"string".methods 
#=> [:include?, :%, :*, :+, :to_c, :count, :unicode_normalize, :unicode_normalize!, :unicode_normalized?, :partition, :unpack, :unpack1, :sum, :next, :casecmp, :casecmp?, :insert, :bytesize, :match, :match?, :succ!, :[email protected], :[email protected], :index, :rindex, :<=>, :replace, :clear, :upto, :getbyte, :==, :===, :setbyte, :=~, :scrub, :[], :[]=, :chr, :scrub!, :dump, :byteslice, :upcase, :next!, :empty?, :eql?, :downcase, :capitalize, :swapcase, :upcase!, :downcase!, :capitalize!, :swapcase!, :hex, :oct, :split, :lines, :reverse, :chars, :codepoints, :prepend, :bytes, :concat, :<<, :freeze, :inspect, :intern, :end_with?, :crypt, :ljust, :reverse!, :chop, :scan, :gsub, :ord, :start_with?, :length, :size, :rstrip, :succ, :center, :sub, :chomp!, :sub!, :chomp, :rjust, :lstrip!, :gsub!, :chop!, :strip, :to_str, :to_sym, :rstrip!, :tr, :tr_s, :delete, :to_s, :to_i, :tr_s!, :delete!, :squeeze!, :each_line, :squeeze, :strip!, :each_codepoint, :lstrip, :slice!, :rpartition, :each_byte, :each_char, :to_f, :slice, :ascii_only?, :encoding, :force_encoding, :b, :valid_encoding?, :tr!, :encode, :encode!, :hash, :to_r, :<, :>, :<=, :>=, :between?, :clamp, :instance_of?, :kind_of?, :is_a?, :tap, :public_send, :remove_instance_variable, :singleton_method, :instance_variable_set, :define_singleton_method, :method, :public_method, :extend, :to_enum, :enum_for, :!~, :respond_to?, :object_id, :send, :display, :nil?, :class, :singleton_class, :clone, :dup, :itself, :taint, :tainted?, :untaint, :untrust, :untrusted?, :trust, :frozen?, :methods, :singleton_methods, :protected_methods, :private_methods, :public_methods, :instance_variable_get, :instance_variables, :instance_variable_defined?, :!, :!=, :__send__, :equal?, :instance_eval, :instance_exec, :__id__] 

一个更有用的列表中，您可能要删除那些从Object继承的方法，像这样

"string".methods - Object.methods 
#=> [:%, :*, :+, :to_c, :count, :unicode_normalize, :unicode_normalize!, :unicode_normalized?, :partition, :unpack, :unpack1, :sum, :next, :casecmp, :casecmp?, :insert, :bytesize, :match, :match?, :succ!, :[email protected], :[email protected], :index, :rindex, :replace, :clear, :upto, :getbyte, :setbyte, :scrub, :[], :[]=, :chr, :scrub!, :dump, :byteslice, :upcase, :next!, :empty?, :downcase, :capitalize, :swapcase, :upcase!, :downcase!, :capitalize!, :swapcase!, :hex, :oct, :split, :lines, :reverse, :chars, :codepoints, :bytes, :concat, :<<, :intern, :end_with?, :crypt, :ljust, :reverse!, :chop, :scan, :gsub, :ord, :start_with?, :length, :size, :rstrip, :succ, :center, :sub, :chomp!, :sub!, :chomp, :rjust, :lstrip!, :gsub!, :chop!, :strip, :to_str, :to_sym, :rstrip!, :tr, :tr_s, :delete, :to_i, :tr_s!, :delete!, :squeeze!, :each_line, :squeeze, :strip!, :each_codepoint, :lstrip, :slice!, :rpartition, :each_byte, :each_char, :to_f, :slice, :ascii_only?, :encoding, :force_encoding, :b, :valid_encoding?, :tr!, :encode, :encode!, :to_r, :between?, :clamp] 

你的情况

，你可能想调用OAuth.methods - Object.methods

更上methods方法here
