hashidsxx's Issues

test suit failed

I am using a different suite library (not gtest), but the test.cpp file seems broken anyways.

Bump up to 1.0

Hi @schoentoon,

I updated the site (http://hashids.org/) + my versions to 1.0. Here's what's different: https://github.com/ivanakimov/hashids.js#changelog (which is not much).

If you want to come over to Hashids group, we'd be glad to have you. Are you still up for maintaining C++ port?

If you have any issues with the site (hashids/hashids.github.io#4) or any issues in general, just ping :]

compiled failed in Visual Studio

When compile the demo src in vs, will get an error.

error C2511: 'hashidsxx::Hashids::Hashids(hashidsxx::Hashids &&)': overloaded member function not found in 'hashidsxx::Hashids'

the __cpluscplus is defined to 199711L , but in the hashids.cpp:71 need

if __cplusplus >= 201103

Hashids::Hashids(Hashids &&that)
: _salt(std::move(that._salt)), _alphabet(std::move(that._alphabet)),
_min_length(that._min_length), _separators(std::move(that._separators)),
_guards(std::move(that._guards)) {}

endif

same as the header file.

How to compress UUID string?

I tried this but it generates a way too long hash v25TOEtz2CqquQ5c4ri7KtDFxQfNxfpoSp9TEKcMRiGTwX

using namespace boost::uuids;

std::string guidString {"3eb3ad5a-a9ae-4216-ab74-d96ea2fd0c96"};
uuid guidBytes {boost::lexical_cast<uuid>(guidString)};

hashidsxx::Hashids hasher {};
std::string hash {hasher.encode(guidBytes.begin(), guidBytes.end())};

std::stringstream ss;
for (uint8_t byte : guidBytes) {
    ss << std::to_string(byte) << ", ";
}

return session->close(
    guidString + "\n" + 
    std::to_string(guidBytes.size()) + "\n" + 
    ss.str() + "\n" + 
    hash
);

This is the equivalent in JS https://codepen.io/anon/pen/KQKKrK
