settings

Global settings for the package.

class sage_acsv.settings.ACSVSettings

Global settings for the package.

This class is used to store global settings for the package. It provides a mechanism to set and get the default settings.

EXAMPLES:

sage: from sage_acsv import ACSVSettings
sage: list(ACSVSettings.Output)
[<OutputFormat.ASYMPTOTIC: 'asymptotic'>,
 <OutputFormat.SYMBOLIC: 'symbolic'>,
 <OutputFormat.TUPLE: 'tuple'>]
sage: ACSVSettings.Output.ASYMPTOTIC
<OutputFormat.ASYMPTOTIC: 'asymptotic'>
sage: ACSVSettings.set_default_output_format("tuple")
sage: ACSVSettings.get_default_output_format()
<OutputFormat.TUPLE: 'tuple'>
sage: ACSVSettings.set_default_output_format("symbolic")
sage: ACSVSettings.get_default_output_format()
<OutputFormat.SYMBOLIC: 'symbolic'>
sage: ACSVSettings.set_default_output_format()
sage: ACSVSettings.get_default_output_format()
<OutputFormat.ASYMPTOTIC: 'asymptotic'>

classmethod get_default_groebner_backend()

Get the default groebner basis backend.

classmethod get_default_kronecker_backend()

Get the default kronecker representation backend.

classmethod get_default_output_format()

Get the default output format chosen when not explicitly specifying one.

classmethod get_logging_level()

Get the logging level for the package.

classmethod get_macaulay2()

Get the Macaulay2 installation path.

classmethod set_default_groebner_backend(backend)

Set the preferred method for performing Groebner Bases and related computations, including groebner.compute_groebner_basis(), groebner.compute_primary_decomposition(), and groebner.compute_radical().

Will default to singular.

INPUT:

• backend – a given GroebnerBackend, a string identifying one, or None to restore the default behavior.

classmethod set_default_kronecker_backend(backend)

Set the preferred method for computing a Kronecker Representation. Will default to the sage_acsv implementation if not specified.

See _kronecker_representation().

INPUT:

• backend – a given KroneckerBackend, a string identifying one, or None to restore the default behavior.

classmethod set_default_output_format(output_format=None)

Set the default output format chosen when not explicitly specifying one.

INPUT:

• output_format – a given OutputFormat, a string identifying one, or None to restore the default behavior.

classmethod set_logging_level(level)

Set the logging level for the package.

INPUT:

• level – a logging level.

EXAMPLES:

sage: from sage_acsv import ACSVSettings
sage: import logging
sage: ACSVSettings.set_logging_level(logging.DEBUG)
sage: ACSVSettings.get_logging_level()
10
sage: ACSVSettings.set_logging_level(logging.INFO)
sage: ACSVSettings.get_logging_level()
20

classmethod set_macaulay2_path(path)

Set the path of the Macaulay2 executable.

INPUT:

• path – a filepath string or \(None\) to run from anywhere
