A customized presenter for Chef::Node objects. Supports variable-length output formats for displaying node data
# File lib/chef/knife/core/node_presenter.rb, line 56 def format(data) if parse_format_option == :json summarize_json(data) else super end end
# File lib/chef/knife/core/node_presenter.rb, line 129 def key(key_text) ui.color(key_text, :cyan) end
Converts a Chef::Node object to a string suitable for output to a terminal. If config or config are set the volume of output is adjusted accordingly. Uses colors if enabled in the ui object.
