Project Description

XCOFDK is an eXtensible, Customizable and Object-oriented Framework Development Kit with the primary purpose of providing:

• complete, reliable life cycle management,

• ready-to-use runtime environment for multithreading.

XCOFDK is designed by the concept of high-level abstraction and implemented to enable rapid development of reliable (embedded) applications by providing a software framework composed of building blocks called subsystems. Subsystems are defined and designed by focusing on their associated, high-level functionality and responsibility represented thru their respective API (Application Programming Interface).

Key characteristics of the design of XCOFDK are:

• completely object-oriented,

• inspired by the design principle KISS,

• general-purpose composition in terms of a software framework,

• applicable for multiple programming languages, e.g. Python, C++, Java,

• applicable for multiple operating systems, e.g Linux, Windows, macOS,

• highly configurable, thus customizable and extensible,

• composed of a collection of well-defined subsystems,

• provides a runtime environment as its major service for execution of tasks,

• thus enabling multithreading by a clear, manageable API to start/stop/abort tasks,

• enabling development of event (or message) driven applications,

• support for (aliveness) monitoring of tasks,

• support for transparant communication subsystem(s),

• support for full life cycle management,

• support for well-defined, coordinated shutdown sequence,

• support for tracking, handling and report of detected failures.

Installation

XCOFDK Starter Edition (SE) is available as the free-of-charge version of XCOFDK for Python 3.11, Linux.

Install using pip:

$> python3.11 -m pip install xcofdk-se

Quick Start

Example below illustrates most simple way to start XCOFDK in Python:

# file: defaultmxu.py

from xcofdk import fwapi


def RunQuickStart() -> bool:
    print('Welcome to quick start of XCOFDK.')

    # indicate that main task is finished / stopped by returning 'False'
    return False


def Main() -> int:
    mxu = fwapi.StartXcoFW(fwStartMXU_=RunQuickStart, bAutoStartMXU_=True)
    res = mxu is not None
    if res:
        res = fwapi.StopXcoFW()
    if not fwapi.JoinXcoFW():
        res = False
    return 0 if res else 1


if __name__ == "__main__":
    exit(Main())

When executed the output of the program should like this:

$> python3.11 -m defaultmxu
