Dependency usage tracking for citations¶
-
sage.misc.citation.
cython_profile_enabled
()¶ Return whether Cython profiling is enabled.
EXAMPLES:
sage: from sage.misc.citation import cython_profile_enabled sage: cython_profile_enabled() # random False sage: type(cython_profile_enabled()) is bool True
-
sage.misc.citation.
get_systems
(cmd)¶ Returns a list of the systems used in running the command
cmd
. Note that the results can sometimes include systems that did not actually contribute to the computation. Due to caching, it could miss some dependencies as well.INPUT:
cmd
- a string to run
Warning
In order to properly support Cython code, this requires that Sage was compiled with the environment variable
SAGE_PROFILE=yes
. If this was not the case, a warning will be given when calling this function.EXAMPLES:
sage: from sage.misc.citation import get_systems sage: get_systems('print("hello")') # random (may print warning) [] sage: integrate(x^2, x) # Priming coercion model 1/3*x^3 sage: get_systems('integrate(x^2, x)') ['ginac', 'Maxima'] sage: R.<x,y,z> = QQ[] sage: I = R.ideal(x^2+y^2, z^2+y) sage: get_systems('I.primary_decomposition()') ['Singular'] sage: a = var('a') sage: get_systems('((a+1)^2).expand()') ['ginac']
