Method: Tml::Tokens::Data#token_values_from_array

Defined in:
lib/tml/tokens/data.rb

#token_values_from_array(params, language, options) ⇒ Object

tr(“Hello user_list!”, “”, => [[user1, user2, user3], :name]}

first element is an array, the rest of the elements are similar to the regular tokens lambda, symbol, string, with parameters that follow

if you want to pass options, then make the second parameter an array as well

tr(“users joined the site”, => [[user1, user2, user3], :name])

tr(“users joined the site”, => [[user1, user2, user3], lambda{|user| user.name]})

tr(“users joined the site”, => [[user1, user2, user3], {:attribute => :name)

tr(“users joined the site”, => [[user1, user2, user3], {:attribute => :name, :value => “<strong>{$0</strong>”})

tr(“users joined the site”, => [[user1, user2, user3], “<strong>{$0</strong>”)

tr(“users joined the site”, => [[user1, user2, user3], :name, {

:limit => 4,
:separator => ', ',
:joiner => 'and',
:remainder => lambda{|elements| tr("#{count||other", :count => elements.size)},
:translate => false,
:expandable => true,
:collapsable => true

})
