v5 changes:
- add json print to print_ap_channel_report()
- minor refactor open_json_object()
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.
