6.1.0 is compatible with c++17 from VS2019?
A default console project in VS2019, append #include "chaiscript/chaiscript.hpp" in the main.cpp and build
the result: many warnings

========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========
the code is dummy:
include "chaiscript/chaiscript.hpp"
include <iostream>
int main(){
std::cout << "Hello World!\n";
}
so, the dummy project will never compile
return to_string(retval); ehre retval is a wchar_t*
and
template<typename T>
static std::string to_string(const T &t_str)
{
return std::string(t_str.begin(), t_str.end());
}
static std::string to_string(const T &t_str)
{
return std::string(t_str.begin(), t_str.end());
}
if T=wchar_t then the result is malformed
That back and forth passing of objects between cpp and the scripting language is something I really need.
Additionally, is chai script multi threaded? Is there any threading support? That's particularly important for events.
Sorry for the questions, wasn't able to deduct this information from the wiki.
Well, please let me know if anyone knows anything about it.
On that note, could anytone tell me please if I can retrieve an arbitrary variable defined in the script file? If I have an object called v in the script, so far the only way I can see to do this is
chai.boxed_cast<SomeType>(chai.eval("v"));

And no worries
I.e.
auto x = SomeType()
auto a = x.property("count"); auto b = x.count
print(a.to_string() + " == " + b.to_string)
Or even just to get the type of an object? It's hard to debug dispatch issues, I have occasions when the backtrace I get from the eval exception isn't quite correct, and I also don't know what types my variables have been resolved to. I had something funky with a pair yesterday, where the instantiation hadn't been bootstrapped.
