Overview

Verchew is an embeddable Python script to check the versions of your project’s system dependencies. Its only external dependency is a Python interpreter, available on macOS and most linux-based operating systems.

Setup

Requirements

• Python 2.7+ or Python 3.3+

Installation

Install verchew with pip:

$ pip install verchew

or directly from the source code:

$ git clone https://github.com/jacebrowning/verchew.git
$ cd verchew
$ python setup.py install

Usage

Create a configuration file (.verchew) with your project’s system dependencies:

[Working Program]

cli = working-program
version = 1.2.

[Newer Working Program]

cli = working-program
version =  4.

[Broken Program]

cli = broken-program
version = 1.2.3

[Missing Program]

cli = missing-program
version = 1.2.3

Run verchew to see if you have the right versions installed:

$ verchew

Checking for Working Program...

$ working-program --version
