Release 0.1.8

New features

• Add amalgamation into a single header file (PR #48):
  • The amalgamated header will be available together with the deliverables from each release.
  • To generate the amalgamated header:

    $ python tools/amalgamate.py c4core_all.hpp
    

  • To use the amalgamated header:
    • Include at will in any header of your project.
    • In one - and only one - of your project source files, #define C4CORE_SINGLE_HDR_DEFINE_NOW and then #include <c4core_all.hpp>. This will enable the function and class definitions in the header file. For example, here's a sample program:

      #include <iostream>
      #define C4CORE_SINGLE_HDR_DEFINE_NOW // do this before the include
      #include <c4core_all.hpp>
      int main()
      {
          for(c4::csubstr s : c4::csubstr("a/b/c/d").split('/'))
              std::cout << s << "\n";
      }

• Add csubstr::is_unsigned_integer() and csubstr::is_real() (PR #49).
• CMake: add alias target c4core::c4core, guaranteeing that the same code can be used with add_subdirectory() and find_package(). (see rapidyaml #173)
• Add support for compilation with emscripten (WebAssembly+javascript) (PR #52).

Fixes

• Fix edge cases with empty strings in span::first(), span::last() and span::range() (PR #49).
• Accept octal numbers in substr::first_real_span() and substr::is_real() (PR #49).
• substr: fix coverage misses in number query methods (PR #49).
• Use single-header version of fast_float (PR #49).
• Suppress warnings triggered from fast_float in clang (-Wfortify-source) (PR #49).
• Add missing inline in src/c4/ext/rng/rng.hpp (PR #49).
• Fix compilation of src/c4/ext/rng/inplace_function.h in C++11 (PR #49).
• Change order of headers, notably in windows_push.hpp (PR #47).
• In c4/charconv.hpp: do not use C4_ASSERT in to_c_fmt(), which is constexpr.
• Fix #53: cmake install targets were missing call to export() (PR #55).
• Fix linking of subprojects with libc++: flags should be forwarded through CMAKE_***_FLAGS instead of being set explicitly per-target (PR #54).
