Clang-based in-game "REPL" console

Clang-based in-game "REPL" console

Goals

  • Use as much existing functionality as possible for implementation
  • No new APIs, no new language bindings
  • Use Clang for state-of-the-art C++11 support and diagnostics
  • Keep It Simple, Stupid

cosi, minimal stuff for easier soci + picojson usage

Usage

First, create the named tuple from list of cosi::field instances. First parameter is name in resulting JSON, second is optional field name in SQL query. If not used, the same name is used for both JSON and SQL.

auto t = cosi::make(
    cosi::string_f  {"data"},
    cosi::int_f     {"integerData", "COUNT(data)"},
    cosi::double_f  {"moreData", "another_table.data"}

);

Compile-time matrix/vector computations in Magnum

Magnum now has compile-time matrix/vector library. With full C++14 support in Clang 3.4 you can throw out nearly all manual precomputations, just slap constexpr on the result and be done with it:

#include <Magnum/Magnum.h>
#include <Magnum/Math/Matrix4.h>

using namespace Magnum;

int main() {
 constexpr auto a = Matrix4::scaling(Vector3::xScale(3.0f))*

Voldemort types in C++14

Inspired with real D language feature: http://wiki.dlang.org/Voldemort_types

Compile in GCC/Clang with -std=c++14.
