class polar2grid.core.script_utils.ArgumentParser(prog=None, usage=None, description=None, epilog=None, parents=[], formatter_class=<class 'argparse.HelpFormatter'>, prefix_chars='-', fromfile_prefix_chars=None, argument_default=None, conflict_handler='error', add_help=True, allow_abbrev=True, exit_on_error=True)

Bases: ArgumentParser

_get_group_actions(group)

Get all the options/actions in a group including those from subgroups of the provided group.

Note

This does not group the subgroup options as their own dictionaries.

parse_args(*args, **kwargs)

Parse arguments to support custom polar2grid ‘subgroup’ behavior.

Parameters:

• subgroup_titles – Groups and their arguments that will be put in a separate dictionary in the ‘subgroup_args’ attribute

• global_keywords – Keywords/arguments that should be added to all subgroup dictionaries

class polar2grid.core.script_utils.ExtendAction(option_strings, dest, nargs=None, const=None, default=None, type=None, choices=None, required=False, help=None, metavar=None)

Bases: Action

Similar to the ‘append’ action, but expects multiple elements instead of just one.

class polar2grid.core.script_utils.ExtendConstAction(option_strings, dest, nargs=0, **kwargs)

Bases: Action

Similar to the ‘append’ action, but expects multiple elements instead of just one.

class polar2grid.core.script_utils.NumpyDtypeList(iterable=(), /)

Bases: list

Magic list to allow dtype objects to match string versions of themselves.

class polar2grid.core.script_utils.SatPyWarningFilter(name='')

Bases: Filter

filter(record)

Determine if the specified record is to be logged.

Returns True if the record should be logged, or False otherwise. If deemed appropriate, the record may be modified in-place.

class polar2grid.core.script_utils.ThirdPartyFilter(ignored_packages, level=30, name='')

Bases: Filter

filter(record)

Determine if the specified record is to be logged.

Returns True if the record should be logged, or False otherwise. If deemed appropriate, the record may be modified in-place.

polar2grid.core.script_utils.create_basic_parser(*args, **kwargs)

polar2grid.core.script_utils.create_exc_handler(glue_name)

polar2grid.core.script_utils.rename_log_file(new_filename)

Rename the file handler for the root logger and the traceback logger.

polar2grid.core.script_utils.setup_logging(console_level=20, log_filename='polar2grid.log', log_numpy=True)

Set up the logger to the console to the logging level defined in the command line (default INFO).

Sets up a file logging for everything, regardless of command line level specified. Adds extra logger for tracebacks to go to the log file if the exception is caught. See exc_handler for more information.

Parameters:

• console_level – Python logging level integer (ex. logging.INFO).

• log_filename – Log messages to console and specified log_filename (None for no file log)

• log_numpy – Tell numpy to log invalid values encountered
