Is it possible to use C-u to choose whether to go to the first decorator or the
function definition? Remember, you can have a bunch of function decorators,
not just one. So going to the first decorator could put you way off from where
you expect.
E.g. if you use click, from Mailman 3:
@click.command(
cls=I18nCommand,
context_settings=dict(help_option_names=['-h', '--help']),
help=_("""\
Master subprocess watcher.
Start and watch the configured runners, ensuring that they stay alive and
kicking. Each runner is forked and exec'd in turn, with the master waiting
on their process ids. When it detects a child runner has exited, it may
restart it.
The runners respond to SIGINT, SIGTERM, SIGUSR1 and SIGHUP. SIGINT,
SIGTERM and SIGUSR1 all cause a runner to exit cleanly. The master will
restart runners that have exited due to a SIGUSR1 or some kind of other
exit condition (say because of an uncaught exception). SIGHUP causes the
master and the runners to close their log files, and reopen then upon the
next printed message.
The master also responds to SIGINT, SIGTERM, SIGUSR1 and SIGHUP, which it
simply passes on to the runners. Note that the master will close and
reopen its own log files on receipt of a SIGHUP. The master also leaves
its own process id in the file specified in the configuration file but you
normally don't need to use this PID directly."""))
@click.option(
'-C', '--config', 'config_file',
envvar='MAILMAN_CONFIG_FILE',
type=click.Path(exists=True, dir_okay=False, resolve_path=True),
help=_("""\
Configuration file to use. If not given, the environment variable
MAILMAN_CONFIG_FILE is consulted and used if set. If neither are given, a
default configuration file is loaded."""))
@click.option(
'--no-restart', '-n', 'restartable',
is_flag=True, default=True,
help=_("""\
Don't restart the runners when they exit because of an error or a SIGUSR1.
Use this only for debugging."""))
@click.option(
'--force', '-f',
is_flag=True, default=False,
help=_("""\
If the master watcher finds an existing master lock, it will normally exit
with an error message. With this option,the master will perform an extra
level of checking. If a process matching the host/pid described in the
lock file is running, the master will still exit, requiring you to manually
clean up the lock. But if no matching process is found, the master will
remove the apparently stale lock and make another attempt to claim the
master lock."""))
@click.option(
'--runners', '-r',
metavar='runner[:slice:range]',
callback=validate_runner_spec, default=None,
multiple=True,
