v3.9.0

• you can now use CTRE as C++ module! with -DCTRE_MODULE=ON (experimental) 🎉
• ctre::range is deprecated and replaced with ctre::search_all

void print_all_string(std::string_view subject) {
  for (auto word: ctre::search_all<"\\w+">(subject)) {
    std::cout << word.to_view() << "\n";
  }
}

• simple ctre::capture_group concept
• capture groups / result type now has .to_optional_number(...) member function which returns std::nullopt if group is not matching

std::optional<int> parse_number(std::string_view) {
  return ctre::match<"([0-9]+)">(subject).to_optional_number();
}

• fixed #305 (missing binary_property first-follow checker

v3.8.1

• fix of error with checked iterators in MSVC when ctre::split range return last item empty
• update cmake project version to mirror release version

v3.8

• ability to build ctll::fixed_string from pointer and std::array (ctll::fixed_string<N>(ctll::construct_from_pointer, ptr))
• improved compatibility issues of operator== and operator!= utf8_iterator and utf8_sentinel

explicit operator bool

conditional [[msvc::flatten]] and explicit operator bool on capture groups, which fixes #275

miscellaneous fixes + switching modes

• switching modes inside pattern (pattern: (?i)AB(?c)AB matches string: "abAB")
• better detection of char8_t support
• fix build failure in libc++ debug mode
• remove some shadowing warnings

case-insensitive matching and look-behind

Support for:

• lookbehind positive (<=abc) and negative (<!abc)
• case insensitive matching for ASCII only ctre::OPERATION<"regex", ctre::case_insensitive>(subject_or_range) (example: ctre::match<"[a-z]+", ctre::case_insensitive>(input)

Notes:
don't use mixes case range when doing case_insensitive:

• [a-z] will match a-zA-Z
• [a-Z] won't match anything (as ascii(a) > ascii(Z))
• [A-z] will match more than you expect A-Z[\]^_a-z + backtick (as I don't know how to type in markdown correctly)

v3.6

• [[:punct:]] behaves as ispunct in C
• fix for several MSVC warnings
• cmake library is using C++20 by default (you can change it back with -DCTRE_CXX_STANDARD=17)
• CI/CD for all supported compilers (+ some fixes along the way)

Unicode 14 support

• updated to Unicode 14
• fix in UTF-16 support in patterns
• better support of C++17 modes on newer compilers

clang 12 support + gcc ranges support
