Constructor Details

#initialize(value = '', options = {}) ⇒ Vedeu::DSL::Truncate

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Returns a new instance of Vedeu::DSL::Truncate.

Parameters:

  • value (String) (defaults to: '')
  • options (Hash<Symbol => Boolean|Fixnum|NilClass|String| Symbol]) (defaults to: {}) —

    ptions [Hash<Symbol => Boolean|Fixnum|NilClass|String| Symbol]

Options Hash (options):

  • name (String|Symbol) —

    The name of the geometry to use to determine the width if the width option is not given.

  • truncate (Boolean) —

    Whether to truncate the value.

  • width (Fixnum) —

    The width of the new value.
