Passes tests for me.
I tried to play with this a little bit, which lead to some questions:
1. Is there any way to get tab-completion to work in this situation:
{{{
sage: groebner = sage.libs.singular.ff.gro<TAB> ? cannot open
`__members__.lib`
? cannot open `__methods__.lib`
? cannot open `trait_names.lib`
? cannot open `_getAttributeNames.lib`
}}}
(If yes, maybe this should be a new ticket.)
2. After I got over my laziness, I typed in the whole thing:
{{{
sage: groebner = sage.libs.singular.ff.groebner
sage: P.<x, y> = QQ[]
sage: I = P.ideal(x^2-y, x+y)
sage: groebner(I)
? error occurred in standard.lib::groebner line 850: `parameter def
i_par; parameter list #; `
---------------------------------------------------------------------------
SystemError Traceback (most recent call
last)
/home/ghitza/<ipython console> in <module>()
SystemError: NULL result without error in PyObject_Call
sage: groebner(I, ring=P)
skipping text from `parameter` error at token `;`
---------------------------------------------------------------------------
SystemError Traceback (most recent call
last)
/home/ghitza/<ipython console> in <module>()
SystemError: NULL result without error in PyObject_Call
sage: from sage.libs.singular.function import SingularLibraryFunction
sage: f = SingularLibraryFunction("groebner")
sage: f(I)
---------------------------------------------------------------------------
SystemError Traceback (most recent call
last)
/home/ghitza/<ipython console> in <module>()
SystemError: NULL result without error in PyObject_Call
}}}
Is this a bug? Or am I doing something silly? If it's the latter, it
would be good if there were an easy way for me to get help from the
documentation. I tried groebner? and groebner?? (which give very
different results) but I couldn't get an answer quickly.
So I feel a little clueless at the moment. I'm hoping your answers will
help me out, and I'll look at this again.
(I still think it's terrific stuff, though!)
