Validating versions and version ranges

[r3ps4J]

Hi!

I want to check if a semver version or version range string is valid. With node-semver I'm using valid(v) (for versions) and validRange(range) (for ranges) to do this. See the following Typescript code:

if (!semver.valid(actualVersion)) {
    return false;
}
if (!semver.validRange(requiredVersion)) {
    return false;
}

Can this be done with your library as well in C++?

For versions I think I can make use of the from_string methods and check the return or error, based on the following from the readme file:

// Non-member from string.
semver::version v5 = semver::from_string(s); // constexpr and may throw.
std::optional<version> v6 = semver::from_string_noexcept(s); // constexpr and no throw.

// From string.
semver::version v7;
v7.from_string(s); // constexpr and may throw.
bool success = v7.from_string_noexcept(s); // constexpr and no throw.

But I'm not sure if something similar is possible for version ranges. What would be the best way to recreate my typescript code in C++ using your library?

I'm a bit new to C++, so let me know if you need more info!
