Git pre-push hook

Checks if the remote branch is master, then asks a confirmation. Based on https://gist.github.com/ColCh/9d48693276aac50cac37a9fce23f9bda, but modified to check the remote name instead of local, making it work also for the really dangerous accidents like below:

git push -f origin e09b7418a310114f6aaf495f969c3859095a99af:master

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

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

#include <iostream>
#include <typeinfo>

auto eh() {
	struct Voldemort {

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))*

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"}

);
