Oh and short but still readable is the objective.
This is a rake task, so much is allowed imo. As in, it doesn't need to be the cleanest code ever.

Ok for fun, but not really an improvement:
1 2 3 4 5 6
desc 'Prints out the status codes and their named symbols. Limit by specifying `code=`, with one or more digits or with the start of a named code.' task :status_codes do lib = 'ActionController::StatusCodes'; require lib.underscore and include lib.constantize longest_symbol = SYMBOL_TO_STATUS_CODE.map { |code, _| code.to_s.length }.max puts STATUS_CODES.keys.sort.map { |code| "#{code} :#{SYMBOL_TO_STATUS_CODE.index(code)} #{STATUS_CODES[code].rjust(longest_symbol)}" }.grep(/(^|:)#{ENV['CODE'] || ENV['code']}/i) end

task :status_codes do require 'action_controller/status_codes' include ActionController::StatusCodes SYMBOL_TO_STATUS_CODE.sort_by(&:last).map do |symbol,status| "%-4s :%-32s %s\n" % [ status, symbol, STATUS_CODES[status] ] end.grep(/(^|:)#{ENV['CODE'] || ENV['code']}/i).display end
This is a rake task that will pretty print the HTTP status codes and their named symbol variants as used in Rails.
You can either list all of them with "$ rake status_codes" or drill down with a specific code or match.
Match all codes starting with "42": $ rake status_code code=42
Match all named codes starting with "re": $ rake status_code code=re
Especially the longest_name line could be a good candidate for refactoring (maybe some stdlib lib?).
