click-lock 0.5.1

Adds locks and timeouts to Click entrypoints.

Where is only one function click_lock.lock_group with the same interface as click.group. You define root group and can use it to declare commands or subgroups:

# example.py
import click
from click_lock import lock_group

cli = lock_group()

@cli.command()
@click.argument('seconds', type=int)
def wait(seconds):
    """Wait for particular amount of seconds"""
    import time
    time.sleep(seconds)

cli()

Now you have some additional options:

Usage: example.py [OPTIONS] COMMAND [ARGS]...

Options:
  --lock fname          Path to lock file
  --timeout seconds     Limit script execution time
  --trace / --no-trace  Log traceback in case of timeout  [default: True]
  --help                Show this message and exit.

Commands:
  wait  Wait for particular amount of seconds

For example, lock script execution:

python example.py --lock /tmp/example.lck wait 10

Limit script execution:

python example.py --timeout 5 wait 10
