Feature for testing the presence of PARI/GP.¶

class sage.features.pari.Gp(*args, **kwds)[source]¶

Bases: Executable

A Feature describing the presence of the gp executable.

EXAMPLES:

Sage

sage: from sage.features.pari import Gp
sage: Gp().is_present()                                # needs sage.libs.pari
FeatureTestResult('gp_executable', True)

Python

>>> from sage.all import *
>>> from sage.features.pari import Gp
>>> Gp().is_present()                                # needs sage.libs.pari
FeatureTestResult('gp_executable', True)

class sage.features.pari.PariFeature(*args, **kwds)[source]¶

Bases: Feature

A Feature describing the presence of a PARI/GP functionality.

EXAMPLES:

Sage

sage: from sage.features.pari import PariFeature
sage: F = PariFeature('pari_seadata', 'ellmodulareqn(211)')
sage: F.is_present()                                   # optional - pari_seadata
FeatureTestResult('pari_seadata', True)

Python

>>> from sage.all import *
>>> from sage.features.pari import PariFeature
>>> F = PariFeature('pari_seadata', 'ellmodulareqn(211)')
>>> F.is_present()                                   # optional - pari_seadata
FeatureTestResult('pari_seadata', True)
