Re: [boost] Boost.Parser questions

When testing I noticed that <algorithm> was missing app/raw.githubusercontent.com/tzlaine/parser/single_header/include/boost/parser/parser_unified.hpp:13853:17: error: no matching function for call to 'find' 13853 | std::find(detail::eol_cps.begin(), detail::eol_cps.end(), c) != | Darrell

* My use case involves parsing identifiers that can only contain ASCII lowercase, uppercase, digits and the underscore.

Spirit used to have helpers like this but Parser doesn't seem to have them. I noticed this too but it's actually pretty easy to fill this in yourself.

Here's a working example: https://godbolt.org/z/6P6dTbGYY

auto const digit = p::char_('0', '9'); auto const lower = p::char_('a', 'z'); auto const upper = p::char_('A', 'Z'); auto const ident = digit | lower | upper | '_';

...

* I started my evaluation using clang-18 (Linux) but builds fail (seems to happen under all clang versions I tried).

Hmm, I can't actually can't replicate this, btw.

I'm using the latest tip of develop here: https://github.com/cmazakas/parser-review/blob/main/overlays/boost-parser/po...

Compiles fine for me using clang-17 on Ubuntu 23.10

You should include details about the nature of your build failures.
