### Public Class Methods

list(obj) click to toggle source

@note The returned string has a leading space except when given an empty list.

Converts an object (often a collection of objects) into an English list.

    list(['banana', 'kiwi', 'mango'])
    #=> " \"banana\", \"kiwi\", and \"mango\""

Given an empty collection, returns the empty string.

    list([]) #=> ""

    # File lib/rspec/matchers/english_phrasing.rb, line 26
    def self.list(obj)
      return " #{RSpec::Support::ObjectFormatter.format(obj)}" if !obj || Struct === obj
      items = Array(obj).map { |w| RSpec::Support::ObjectFormatter.format(w) }
      case items.length
      when 0
        ""
      when 1
        " #{items[0]}"
      when 2
        " #{items[0]} and #{items[1]}"
      else
        " #{items[0...-1].join(', ')}, and #{items[-1]}"
      end
    end

Converts a symbol into an English expression.

    split_words(:banana_creme_pie) #=> "banana creme pie"

    # File lib/rspec/matchers/english_phrasing.rb, line 9
    def self.split_words(sym)
      sym.to_s.gsub(/_/, ' ')
    end
