54 /* This is a clever little trick to make writing the various object reprs
55 * easier. It relies on Python's %V format option which consumes two
56 * arguments. The first is a unicode object which may be NULL, and the second
57 * is a char* which will be used if the first parameter is NULL.
59 * The issue is that we don't know whether the `parent_repr` at the call site
60 * is a unicode or a bytes (a.k.a. 8-bit string). Under Python 3, it will
61 * always be a unicode. Under Python 2 it will *probably* be a bytes/str, but
62 * could potentially be a unicode. So, we check the type, and if it's a
63 * unicode, we pass that as the first argument, leaving NULL as the second
64 * argument (since it will never be checked). However, if the object is not a
65 * unicode, it better be a bytes. In that case, we'll pass NULL as the first
66 * argument so that the second one gets used, and we'll dig the char* out of
67 * the bytes object for that purpose.
69 * You might think that this would crash if obj is neither a bytes/str or
70 * unicode, and you'd be right *except* that Python doesn't allow any other
71 * types to be returned in the reprs. Also, since obj will always be the repr
72 * of a built-in type, it will never be anything other than a bytes or a
73 * unicode in any version of Python. So in practice, this is safe.
