Boost.Parser (Part 1 of 2) - A Parser Combinator Library for C++
summary
Boost.Parser is a new Boost candidate (C++17+) that grafts Spirit 2’s ergonomics onto X3’s modernization, claiming much shorter compile times and safer diagnostics. It exposes parse / prefix_parse overloads with skipper support, uses Boost.Charon for fast numeric parsing, and implements container-aware attribute insertion so parsed sequences can be fed directly into sets, vectors or user structs. Parsers are cheap to construct (no hidden allocations), support permutation, expectation points, semantic actions, and a small set of documented collapsing rules for predictable attribute types.
