# File 'rspec-core/lib/rspec/core/formatters/console_codes.rb', line 34
def config_colors_to_methods @config_colors_to_methods ||= Configuration.instance_methods.grep(/_color\z/).inject({}) do |hash, method| hash[method.to_s.sub(/_color\z/, '').to_sym] = method hash end end
.console_code_for(code_or_symbol) ⇒ Fixnum (mod_func)
Fetches the correct code for the supplied symbol, or checks that a code is valid. Defaults to white (37).
# File 'rspec-core/lib/rspec/core/formatters/console_codes.rb', line 47
def console_code_for(code_or_symbol) if (config_method = config_colors_to_methods[code_or_symbol]) console_code_for RSpec.configuration.__send__(config_method) elsif VT100_CODE_VALUES.key?(code_or_symbol) code_or_symbol else VT100_CODES.fetch(code_or_symbol) do console_code_for(:white) end end end
.wrap(text, code_or_symbol) ⇒ String (mod_func)
Wraps a piece of text in ANSI codes with the supplied code. Will only apply the control code if RSpec.configuration.color_enabled? returns true.
# File 'rspec-core/lib/rspec/core/formatters/console_codes.rb', line 66
def wrap(text, code_or_symbol) if RSpec.configuration.color_enabled? "\e[#{console_code_for(code_or_symbol)}m#{text}\e[0m" else text end end
