P1967 - #embed

[ThePhD]

#embed is a pre-processor directive for the inclusion of binary data into a program through implementation-defined resource lookup.

Latest draft is: https://thephd.github.io/vendor/future_cxx/papers/source/C%20-%20embed

I now have to figure out how

#embed [bits-per-element]opt [max-elements]opt header-name

can be done. Disambiguation of the numeric constant for bits-per-element versus max-elements means you cannot specify just one of them and have the preprocessor know which one...

[ThePhD]

This paper is on track. The next time it is seen it will just be

#embed [max-elements]opt header-name

It will always produce a comma-delimited sequence of unsigned char. Just need to update the paper now.

The wording needed a lot of work, so we fixed it up quite a bit:

Not sure where to best put this, but I found this issue so I'll comment here. Comments apply to draft proposal of June 15, 2021.

• 2.1 "Others pointed out that ... is very dangerous to portably." Should be "portability"?
• 2.2 The link to std::embed displays the markdown source in the rendered document
• 3.2.1 "Speed Size". Should this just be "Speed"?
• 3.2.3 "require an extremely large refactor and functionality add of parser internals" Not sure "add" is the right word here?
• 4.4 "casted" should probably just be "cast"
• 4.6 you probably also want to #include <cstdio> if you're including includes in the example
• 4.6 the section talks about fread() into an array of ints, but the example uses unsigned char
• 8 the the includecpp.org link is also not rendered correctly
• 9.1.4 the incbin link isn't rendered correctly
• 9.2 at the end "the proposal now let’s the implementation "figure it out"" should be "lets" without the apostrophe

When I refer to links that don't render correctly, this is the document I'm looking at: https://thephd.dev/_vendor/future_cxx/papers/d1967.html

Thanks for looking out; these have all been edited / fixed.

C++ paper has been split off into it's own thing. Which looks prettier because it uses bikeshed now:

C++ and C papers have been properly split up. Wording is based on which link you travel:
