Installation
============
TinyFSM is an header-only library, no special installation steps are
needed. Just point your compiler to the "include" directory, and in
your source files:
#include <tinyfsm.hpp>
Prerequisites
-------------
TinyFSM requires a compiler supporting the C++11 language standard
("-std=c++11" in gcc).
TinyFSM does not depend on RTTI, exceptions or any external library.
If you need to compile without standard libraries (e.g. in conjunction
with `-nostdlib` linker option), add `-DTINYFSM_NOSTDLIB` to the
compiler options: this removes all dependencies on the standard
library by disabling some compile-time type checks.
Building the Elevator Example
-----------------------------
Change to the elevator example directory and compile the sources:
$ cd examples/elevator
$ make
Our elevator has call buttons on every floor, sensors reporting the
current position, and an alarm button for emergency. These actors can
be triggered via a simple command interface:
$ ./elevator
Motor: stopped
Motor: stopped
c=Call, f=FloorSensor, a=Alarm, q=Quit ?
Let's call the elevator to floor 2:
c=Call, f=FloorSensor, a=Alarm, q=Quit ? c
Floor ? 2
Motor: moving up
c=Call, f=FloorSensor, a=Alarm, q=Quit ?
Now the elevator is moving up, and we need to trigger the floor sensor:
c=Call, f=FloorSensor, a=Alarm, q=Quit ? f
Floor ? 1
Reached floor 1
c=Call, f=FloorSensor, a=Alarm, q=Quit ? f
Floor ? 2
Reached floor 2
Motor: stopped
c=Call, f=FloorSensor, a=Alarm, q=Quit ?
Now we simulate a sensor defect:
c=Call, f=FloorSensor, a=Alarm, q=Quit ? c
Floor ? 1
Motor: moving down
c=Call, f=FloorSensor, a=Alarm, q=Quit ? f
Floor ? 2
Floor sensor defect (expected 1, got 2)
*** calling maintenance ***
Motor: stopped
