Question: PEP 3118 format strings and the buffer protocol

[pitrou (Antoine Pitrou)]

by documented I mean documented on docs.python.org. At least a link to the proposal would be good, though an actual explanation would be better. I think the usual standard for being documented isn’t “the information exists in a proposal but docs.python.org does not mention the proposal and contradicts it.

Ah, fair enough. Yes, PEP 3118 should be linked to in relevant portions of those docs. For example, it should be mentioned in the C API doc to Py_buffer::format.

@hoodmane

• Meador Inge and others seems to suggest that 3118 is overly vague and in particular leaves it unclear what a grammar for the format strings is implement PEP 3118 struct changes · Issue #47382 · python/cpython · GitHub

Hmm, to be honest, I don’t think the most complex parts of PEP 3118 will ever be implemented anywhere (does any library make use of the “pointer” prefix? or of suboffsets?).
