flisboac / test-constexpr-elements-set-2.cpp
Last active December 30, 2016 07:54
Note: C++11 has a crappy std::array API for constexpr usage. Why, standard bodies? Why?
// This is a better version (i think), it does not use std::get().
#include <iostream>
#include <array>
template <typename T, T T1, T... Ts>
struct ConstexprSetHelper {
constexpr static size_t size = 1 + sizeof...(Ts);
constexpr static bool contains(T elem) {
return (elem == T1) || ConstexprSetHelper<T, Ts...>::contains(elem);

flisboac / test-simple-facade-with-sfinae.cpp
Created January 22, 2017 04:27
C++11: Testing a combination of a (possibly constexpr) facade from various adapters to concrete classes. Possible use on concept checking. (saying no to Boost, before someone asks!)
// compiled as in: `g++ -std=c++1y 'test-facade-through-sfinae.cpp' -o 'test-facade-through-sfinae'
#include <iostream>
template <typename T, template <typename TTTs> class... TTs>
struct facade : public TTs<T>... {
facade(T& t): state__(&t) {}
constexpr inline operator T&() { return *state__; }
private:
T* state__;

silly gist hack, why do we need you? :(

Last active July 25, 2018 17:26
Forcibly deletes/purges individual artifact coordinates from a default-layout M2 repository, without using `mvn` or downloading any dependency tree. (P.S.: Does not work with transitive dependencies! For that, use https://maven.apache.org/plugins/maven-dependency-plugin/purge-local-repository-mojo.html)
