Tests for the IPython integration

First, test the pinfo magic for Python code. This is what IPython calls when you ask for the single-questionmark help, like \(foo?\)

sage: from sage.repl.interpreter import get_test_shell
sage: shell = get_test_shell()
sage: shell.run_cell(u'from sage.repl.ipython_tests import dummy')
sage: shell.run_cell(u'%pinfo dummy')
Signature:      dummy(argument, optional=None)
Docstring:
   Dummy Docstring Title

   Dummy docstring explanation.

   INPUT:

   * "argument" -- anything. Dummy argument.

   * "optional" -- anything (optional). Dummy optional.

   EXAMPLES:

...
Init docstring: ...ee help(type(...)) for...signature...
File:           .../sage/repl/ipython_tests.py
Type:           function

Next, test the pinfo magic for Cython code:

sage: from sage.repl.interpreter import get_test_shell
sage: shell = get_test_shell()
sage: shell.run_cell(u'from sage.tests.stl_vector import stl_int_vector')
sage: shell.run_cell(u'%pinfo stl_int_vector')
...
   Example class wrapping an STL vector

   EXAMPLES:

...
Init docstring: ...ee help(type(...)) for...signature...
File:           .../sage/tests/stl_vector.pyx
Type:           type
...

Next, test the pinfo magic for R interface code, see trac ticket #26906:

sage: from sage.repl.interpreter import get_test_shell   # optional - rpy2
sage: shell = get_test_shell()                           # optional - rpy2
sage: shell.run_cell(u'%pinfo r.lm')                     # optional - rpy2
Signature:       r.lm(...*args, **kwds)
...
String form:     lm
File:            .../sage/interfaces/r.py
Docstring:

Next, test the pinfo2 magic for Python code. This is what IPython calls when you ask for the double-questionmark help, like \(foo??\)

sage: from sage.repl.interpreter import get_test_shell
sage: shell = get_test_shell()
sage: shell.run_cell(u'from sage.repl.ipython_tests import dummy')
sage: shell.run_cell(u'%pinfo2 dummy')
Signature: dummy(argument, optional=None)
...
Source:
def dummy(argument, optional=None):
    """
    Dummy Docstring Title

    Dummy docstring explanation.

    INPUT:

    - ``argument`` -- anything. Dummy argument.

    - ``optional`` -- anything (optional). Dummy optional.

    EXAMPLES::

    ...
    """
    return 'Source code would be here'
File:      .../sage/repl/ipython_tests.py
Type:      function

Next, test the pinfo2 magic for Cython code:

sage: from sage.repl.interpreter import get_test_shell
sage: shell = get_test_shell()
sage: shell.run_cell(u'from sage.tests.stl_vector import stl_int_vector')
sage: shell.run_cell(u'%pinfo2 stl_int_vector')
...
cdef class stl_int_vector(SageObject):
    """
    Example class wrapping an STL vector

    EXAMPLES::

...
    """

    cdef vector[int] *data
    cdef string *name

    def __cinit__(self):
        """
        The Cython constructor.

        EXAMPLES::

...
File:   .../sage/tests/stl_vector.pyx
Type:   type
...

Next, test the pinfo2 magic for R interface code, see trac ticket #26906:

sage: from sage.repl.interpreter import get_test_shell   # optional - rpy2
sage: shell = get_test_shell()                           # optional - rpy2
sage: shell.run_cell(u'%pinfo2 r.lm')                    # optional - rpy2
Signature:       r.lm(...*args, **kwds)
...
String form:     lm
File:            .../sage/interfaces/r.py
Source:
function (formula, data, subset, weights, na.action, method = "qr",
...

Test that there are no warnings being ignored internally:

sage: import warnings
sage: warnings.simplefilter('error');  get_test_shell()
<sage.repl.interpreter.SageTestShell object at 0x...>
sage.repl.ipython_tests.dummy(argument, optional=None)

Dummy Docstring Title

Dummy docstring explanation.

INPUT:

  • argument – anything. Dummy argument.

  • optional – anything (optional). Dummy optional.

EXAMPLES:

sage: from sage.repl.ipython_tests import dummy
sage: dummy(1)
'Source code would be here'
