This avoids C++'s standard library regexes, which aren't the same across platforms, and have many other issues, like using stack so much that they stack overflow when processing a lot of data. To avoid backwards and forward compatibility issues, regexes are processed using a function converting libstdc++ regexes into Boost regexes, escaping characters that Boost needs to have escaped, and rejecting features that Boost has and libstdc++ doesn't. Related context: - Original failed attempt to use `boost::regex` in CppNix, failed due to boost icu dependency being large (disabling ICU is no longer necessary because linking ICU requires using a different header file, `boost/regex/icu.hpp`): https://github.com/NixOS/nix/pull/3826 - An attempt to use PCRE, rejected due to providing less backwards compatibility with `std::regex` than `boost::regex`: https://github.com/NixOS/nix/pull/7336 - Second attempt to use `boost::regex`, failed due to `}` regex failing to compile (dealt with by writing a wrapper that parses a regular expression and escapes `}` characters): https://github.com/NixOS/nix/pull/7762 Closes #34. Closes #476. Change-Id: Ieb0eb9e270a93e4c7eed412ba4f9f96cb00a5fa4
