xstate-cpp

I needed xstate in C++. Here we are

Features

• Basic stuff (I dunno I'm new here I just wanted a state machine for myself ☃)
• Nested state machines just landed in by #5 - see ./example.cpp for an example.
• Others coming in real soon. Actually, even sooner, if you wanna contribute:P

Installation

• platformio

platformio lib install --save XState-cpp

For everything else, you need to compile all .cpp files - makefile coming soon.

• git + submodules

git submodules add https://github.com/sarpik/xstate-cpp.git
# or:  git submodules add git@github.com/sarpik/xstate-cpp.git

git submodules update --init --recursive

g++ -std=c++11 ./xstate-cpp/src/*.cpp ./xstate-cpp/example.cpp -o example.out
./example.out

• git

git clone https://github.com/sarpik/xstate-cpp.git
# or:  git clone git@github.com:sarpik/xstate-cpp.git

g++ -std=c++11 ./xstate-cpp/src/*.cpp ./xstate-cpp/example.cpp -o example.out
./example.out

obviously, you subsitute example.cpp with your own source files & get some spicy state machines. 🌶

Usage

See also ./example.cpp

#include <iostream>
#include "xstate.h"

using namespace std;
using namespace xs;

int main() {
  StateMachine machine = {
    .id = "light",
    .initial = "green",
    .states = {
      {
        "green" ,
        { .on = { { "TIMER", "yellow" } } }
      },
      {
        "yellow",
        { .on = { { "TIMER", "red"    } } }
      },
      {
        "red"   ,
        { .on = { { "TIMER", "green"  } } }
      }
    }
  };

  Interpreter *toggleMachine = interpret(machine)
    ->logInfo()
    ->onStart([]() {
      cout << "let's go!\n";
    })
    ->onTransition([](Interpreter *self) {
      self->logInfo();
    })
    ->onStop([]() {
      cout << "oh no we stopped c:\n";
    })
    ->start();

  toggleMachine->send("TIMER");

  toggleMachine->send("TIMER");

  toggleMachine->send("TIMER");

  toggleMachine->stop();

  delete toggleMachine;

  return 0;
}

compile with:

g++ -std=c++11

for example,

g++ -std=c++11 ./src/*.cpp ./example.cpp -o example.out

& run with

./example.out

I use ./go
