jp: --output option: - new --output option can be added wich use_output. use_output can be True (in which case it wild default to C.OUTPUT_TEXT), or any of C.OUTPUT_TYPES (currently text, list and dict) - output change the output format mainly to make command result parsing more easy, but it can also be use to add fancy effects (like coloration) - outputs are added with plugins in the same way as commands (import of both is done in the same method) - in the command class, output need to be declared with use_output=C.OUTPUT_xxx, then the data only need to be processed with self.output(data) - outputs can have description (not used yet) - use_xxx argument handling has been refactored (minor refactoring) to be more generic - first outputs are "default", "json" (pretty printed) and "json_raw" (compact json) - the first command to use them is "profile list"
