2025-07-13tools: ynl: default to --process-unknown in installed modeJakub Kicinski
We default to raising an exception when unknown attrs are found to make sure those are noticed during development. When YNL CLI is "installed" and used by sysadmins erroring out is not going to be helpful. It's far more likely the user space is older than the kernel in that case, than that some attr is misdefined or missing.

2025-05-09tools: ynl: handle broken pipe gracefully in CLIDonald Hunter
When sending YNL CLI output into a pipe, closing the pipe causes a BrokenPipeError. E.g. running the following and quitting less: ./tools/net/ynl/pyynl/cli.py --family rt-link --dump getlink | less Traceback (most recent call last): File "/home/donaldh/net-next/./tools/net/ynl/pyynl/cli.py", line 160, in <module> main() ~~~~^^ File "/home/donaldh/net-next/./tools/net/ynl/pyynl/cli.py", line 142, in main output(reply) ~~~~~~^^^^^^^ File "/home/donaldh/net-next/./tools/net/ynl/pyynl/cli.py", line 97, in output pprint.PrettyPrinter().pprint(msg) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^^^^^ [...] BrokenPipeError: [Errno 32] Broken pipe Consolidate the try block for ops and notifications, and gracefully handle the BrokenPipeError by adding an exception handler to the consolidated try block.

2025-01-13tools/net/ynl: add support for --family and --list-familiesDonald Hunter
Add a --family option to ynl to specify the spec by family name instead of file path, with support for searching in-tree and system install location and a --list-families option to show the available families. ./tools/net/ynl/pyynl/cli.py --family rt_addr --dump getaddr Signed-off-by: Donald Hunter <donald.hunter@gmail.com> Link: https://patch.msgid.link/20250111154803.7496-1-donald.hunter@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-01-09tools: ynl: move python code to separate sub-directoryJan Stancek
Move python code to a separate directory so it can be packaged as a python module. Updates existing references in selftests and docs. Also rename ynl-gen-[c|rst] to ynl_gen_[c|rst], avoid dashes as these prevent easy imports for entrypoints.
