How it works: text output: Tabs for text output is based on json depth. For example: ssid is depth 3 or something so 3 tabs will be printed before "SSID: %s" json output: iw_printf will print number (without "") or text based on passed format. For all number formats. Formats: %d %i %p %hu etc will print without quotes If else format is passed iw_print will print it with quotes. To make it work some new functions added. branch: v5.19 This commit introduces the ability to output scan results from 'iw' in JSON format, similar to the 'ip' utility from the iproute2 package. The addition aims to enhance the tool's usability and scriptability by providing a structured data format option. Two new command-line options are added: - '-j': Outputs scan results in compact JSON format. - '-jj': Outputs scan results in pretty-printed JSON format. The implementation focuses on modifying the printing functions to format the output as JSON without altering the existing netlink response parsing logic. This patch demonstrates the concept with scan results, showcasing the potential for expanding JSON support to other 'iw' functionalities. If these changes prove valuable, I am prepared to continue working on extending JSON output support throughout the tool. Feedback is welcome and appreciated. Thank you.
