io.isis_serial_number — Generate ISIS3 Compliant Serial Numbers

The io.isis_serial_number, using translation tables loaded using the io.io_db module supports generation of ISIS3 compliant serial numbers. These are necessary when creating ISIS3 compliant control networks.

New in version 0.1.0.

class plio.io.isis_serial_number.SerialNumberDecoder(grammar=None, quantity_cls=None)

A PVL Decoder class to handle cube label parsing for the purpose of creating a valid ISIS serial number. Inherits from the PVLDecoder in planetarypy’s pvl module.

decode_simple_value(value: str)

Returns a Python object based on value, assuming that value can be decoded as a PVL Simple Value:

<Simple-Value> ::= (<Numeric> | <String>)

Modified from https://pvl.readthedocs.io/en/stable/_modules/pvl/decoder.html#PVLDecoder.decode_simple_value
Modification entails stripping datetime from list of functions.

decode_unquoted_string(value: str) → str

Returns a Python str if value can be decoded as an unquoted string, based on this decoder’s grammar. Raises a ValueError otherwise.

Modified from: https://pvl.readthedocs.io/en/stable/_modules/pvl/decoder.html#PVLDecoder.decode_unquoted_string Modification entails removal of decode_datetime call
