Class | Inflector::Inflections |
In: |
lib/assistance/inflector.rb

Parent: | Object |
A singleton instance of this class is yielded by Inflector.inflections, which can then be used to specify additional inflection rules. Examples:
Inflector.inflections do |inflect| inflect.plural /^(ox)$/i, '\1\2en' inflect.singular /^(ox)en/i, '\1' inflect.irregular 'octopus', 'octopi' inflect.uncountable "equipment" end
New rules are added at the top. So in the example above, the irregular rule for octopus will now be the first of the pluralization and singularization rules that is runs. This guarantees that your rules run before any of the rules that may already have been loaded.
plurals | [R] | |
singulars | [R] | |
uncountables | [R] |
# File lib/assistance/inflector.rb, line 27 27: def initialize 28: @plurals, @singulars, @uncountables = [], [], [] 29: end
Clears the loaded inflections within a given scope (default is :all). Give the scope as a symbol of the inflection type, the options are: :plurals, :singulars, :uncountables
Examples:
clear :all clear :plurals
# File lib/assistance/inflector.rb, line 70 70: def clear(scope = :all) 71: case scope 72: when :all 73: @plurals, @singulars, @uncountables = [], [], [] 74: else 75: instance_variable_set "@#{scope}", [] 76: end 77: end
Specifies a new irregular that applies to both pluralization and singularization at the same time. This can only be used for strings, not regular expressions. You simply pass the irregular in singular and plural form.
Examples:
irregular 'octopus', 'octopi' irregular 'person', 'people'
# File lib/assistance/inflector.rb, line 49 49: def irregular(singular, plural) 50: plural(Regexp.new("(#{singular[0,1]})#{singular[1..-1]}$", "i"), '\1' + plural[1..-1]) 51: singular(Regexp.new("(#{plural[0,1]})#{plural[1..-1]}$", "i"), '\1' + singular[1..-1]) 52: end
Specifies a new pluralization rule and its replacement. The rule can either be a string or a regular expression. The replacement should always be a string that may include references to the matched data from the rule.
# File lib/assistance/inflector.rb, line 33 33: def plural(rule, replacement) 34: @plurals.insert(0, [rule, replacement]) 35: end
Specifies a new singularization rule and its replacement. The rule can either be a string or a regular expression. The replacement should always be a string that may include references to the matched data from the rule.
# File lib/assistance/inflector.rb, line 39 39: def singular(rule, replacement) 40: @singulars.insert(0, [rule, replacement]) 41: end
Add uncountable words that shouldn‘t be attempted inflected.
Examples:
uncountable "money" uncountable "money", "information" uncountable %w( money information rice )
# File lib/assistance/inflector.rb, line 60 60: def uncountable(*words) 61: (@uncountables << words).flatten! 62: end
