Discussed in today's EWG telecon.

Polls:

We want #embed [optional limit] header-name (no type name, no other specification) as a feature.

SF	F	N	A	SA

We want to explore allowing an optional sequence of tokens to specify a type to #embed.

[AaronBallman]

This paper has progressed within WG14 and WG21 and no longer needs SG22 involvement unless the author desires it, so removing the label.

D1967(To be R7) was discussed during the EWG 6/23/2022 Telecon, and the following poll was taken:

EWG encourages P1967 to define the form of vendor extensions as parameters to #embed?	SF	F	N	A	SA
4	4	3	1	0

Result: Consensus

Author expected to return with a revisioned paper based on the feedback received during this meeting.

[wg21bot]

P1967R9 #embed - a simple, scannable preprocessor-based resource acquisition method (JeanHeyd Meneide)

[erichkeane]

Forward P1967R9, with both 'optional' sections included to CWG for inclusion in C++26. This is as WG14 accepted.

SF	F	N	A	SA
7	5	2	2	2

Result: Stronger Consensus

Forward P1967R9, including section 7.3.6 (__has_embed with return value 2), but not 7.3.7 (prefix/suffix/if_empty) to CWG for inclusion in C++26. This diverges from what was accepted by WG14.

SF	F	N	A	SA
6	6	4	3	2

Result: Weaker Consensus

The former poll has greater consensus, so EWG is forwarding P1967R9 and both optional sections.

[jensmaurer]

The author intends to add preprocessor constants __STDC_EMBED_NOT_FOUND__, __STDC_EMBED_FOUND__, and __STDC_EMBED_EMPTY__. Back to EWG for approval of that change.

P1967R10 #embed - a simple, scannable preprocessor-based resource acquisition method (JeanHeyd Meneide)

[erichkeane]

This was discussed during the Feb 6, 2023 Morning Session in Issaquah, and the following polls were taken:

P1967 should include the macro'ed textual versions of has-embed-expressions results, as proposed (and as accepted by WG14).	SF	F	N	A	SA
20	12	2	1	0

Result: Consensus

P1967 should remove embed-standard-parameter 'prefix', 'suffix', and/or 'if_empty', if WG14 also chooses to do so, for the purposes of C compatibility of this feature.	SF	F	N	A	SA
7	17	6	0	3

Result: Consensus

Forward P1967R10 (as modified by the above polls/WG14) to CWG.	SF	F	N	A	SA

Result: Unanimous Consent

P1967R12 #embed - a simple, scannable preprocessor-based resource acquisition method (JeanHeyd Meneide, )

[IRainman]

I'm waiting for it, since 2002, and I really suffer every time that I need it and completely don't understand why that very simple feature doesn't include in C++ before.
