• header-only C++11
• parses semver string
• inspired by Semantic Versioning and npm-semver

• semver::valid( v ): return true if the given version or range is syntactically and semantically valid.
• semver::intersects( range1, range2="*" ): return true if the given version ranges or comparators intersect.
• semver::satisfies( version, range ): return true if the version satisfies the range.
• semver::gt( v1, v2 ), semver::gte( v1, v2 ), semver::lt( v1, v2 ), semver::lte( v1, v2 ), semver::eq( v1, v2 ), semver::neq( v1, v2 ), semver::gtr( version, range ), semver::ltr( version, range ): various comparators.
• semver::prerelease( version ), semver::major( version ), semver::minor( version ), semver::patch( version ): get version parts if possible.

// example/demo.cpp

#include "cpp-semver.hpp"
#include <iostream>

int main()
{
  {
    const std::string ver1 = "1.0.0 || 1.5 - 3.0";
    const std::string ver2 = ">1.1 <2.0";

    const bool intersected = semver::intersects(ver1, ver2);

    std::cout << "\"" << ver1
      << "\" and \"" << ver2
      << "\" are " << (intersected ? "" : "not ")
      << "intersected." << std::endl;
  }

  {
    const std::string comp = "<1.* >2.2";

    const bool intersected = semver::intersects(comp);

    std::cout << "\"" << comp
      << "\" is " << (intersected ? "" : "not ")
      << "intersected." << std::endl;
  }

  return 0;
}

To build:

> g++ -std=c++11 -Iinclude example/demo.cpp

Or build with optional PEGTL parser: (to cross test, or to quickly evaluate any grammar change for development purpose.)

> git submodule update --init --recursive
> g++ -std=c++11 -D USE_PEGTL -Iinclude -IPEGTL/include example/demo.cpp

The result:

> ./a.out
"1.0.0 || 1.5 - 3.0" and ">1.1 <2.0" are intersected.
"<1.* >2.2" is not intersected.
