split_commas

lsst.daf.butler.cli.utils.split_commas(context, param, values)

Process a tuple of values, where each value may contain comma-separated values, and return a single list of all the passed-in values.

This function can be passed to the ‘callback’ argument of a click.option to allow it to process comma-separated values (e.g. “–my-opt a,b,c”).

Parameters:

contextclick.Context or None

The current execution context. Unused, but Click always passes it to callbacks.

paramclick.core.Option or None

The parameter being handled. Unused, but Click always passes it to callbacks.

values[str]

All the values passed for this option. Strings may contain commas, which will be treated as delimiters for separate values.

Returns:

list of string

The passed in values separated by commas and combined into a single list.
