see https://gist.github.com/mtao/172c73a4a7abdf7a5724b71523a5fbe8, but for matlab; mtao imports are findable here: https://github.com/mtao/core/blob/master/include/mtao/eigen/stack.h

mtao / enumerate_sb_it.cpp
Created December 28, 2017 15:13
stupidly joked that ``c++ is turning into compiled python'' and was sent ``pairs = dict(enumerate([1, 5, 4, 3, 2])); print(pairs)''
#include <map>
#include <tuple>
#include <iostream>
template <typename IteratorType>
struct enumerate {
using value_type = std::pair<int,std::remove_pointer_t<IteratorType>>;
struct enum_iter {
IteratorType it;
int idx = 0;

turns out structured bindings work in ranged for loops!
#include <map>
#include <iostream>
int main() {
std::map<int,int> pairs;
pairs[0] = 1;
pairs[1] = 5;
pairs[2] = 4;
pairs[3] = 3;

mtao / structured_bindnig_array.cpp
Created December 22, 2017 05:03
just a quick example of why structured bindings make live easier
#include <array>
#include <iostream>
int main() {
std::array<int,2> size = {640,480};
auto [w,h] = size;
std::cout << w << " " << h << std::endl;

mtao / static_if.cpp
Created December 21, 2017 00:23
if (and presumably for) can have static variables in initialization. test is due to me trying to not pollute my namespaces with static variables with imgui Raw
#include <iostream>
void run() {
if(static bool f = false; f) {
std::cout << "true!" << std::endl;
f = false;
} else {
std::cout << "false!" << std::endl;
f = true;

mtao / daemon.cpp
Created December 5, 2017 04:09
simple example for using cpp thread / mutex / condition_variable to toggle running a daemon in the background
#include <iostream>
#include <condition_variable>
#include <thread>
#include <chrono>
#include <mutex>
#include <atomic>
std::condition_variable activity_cv;
std::mutex activity_mutex;
std::atomic<bool> run_daemon = false;

mtao / lhs_determined_returns.cpp
Created November 13, 2017 20:29
a bizarre (working) attempt at getting c++ to "see" the functions on the lhs of an equals sign.
#include <tuple>
#include <functional>
#include <iostream>
template <int N>
struct int_c {constexpr static int value = N;};
template <typename CallType>
