A Formatter object formats an output object (using #format_output) into a string based on the views defined for its class and/or ancestry.
This config is used by #format_output to lazily load dynamic views defined with Hirb::DynamicView. This hash has the same format as #config.
Array of classes whose objects respond to :to_a and allow the first element of the converted array to determine the output class.
Adds the view for the given class and view hash config. See #config for valid keys for view hash.
# File lib/hirb/formatter.rb, line 42 def add_view(klass, view_config) @klass_config.delete(klass) @config[klass.to_s] = view_config true end
A hash of Ruby class strings mapped to view hashes. A view hash must have at least a :method, :output_method or :class option for a view to be applied to an output. A view hash has the following keys:
Specifies a global (Kernel) method to do the formatting.
Specifies a class to do the formatting, using its render() class method. If a symbol it's converted to a corresponding Hirb::Helpers::* class if it exists.
Specifies a method or proc to call on output before passing it to a helper. If the output is an array, it's applied to every element in the array.
Options to pass the helper method or class.
Boolean which when true causes subclasses of the output class to inherit its config. This doesn't effect the current output class. Defaults to false. This is used by ActiveRecord classes.
Examples: {'WWW::Delicious::Element'=>{:class=>'Hirb::Helpers::ObjectTable', :ancestor=>true, :options=>{:max_width=>180}}} {'Date'=>{:class=>:auto_table, :ancestor=>true}} {'Hash'=>{:method=>:puts}}

This method looks for an output object's view in #config and then ::dynamic_config. If a view is found, a stringified view is returned based on the object. If no view is found, nil is returned. The options this class takes are a view hash as described in #config. These options will be merged with any existing helper config hash an output class has in #config. Any block given is passed along to a helper class.
