Overview

When onboarding new team members, ensuring their computer has everything needed to work on the project can be painful. Verchew is a command-line program and embeddable Python script to check the versions of your project's system dependencies. Its only external dependency is any Python interpreter, which should already be installed 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

or embedded the script in your project using this guide.

Usage

Create a configuration file (.verchew.ini) containing your project's system dependencies:

[Working Program]

cli = working-program
version = 1.2.

[Newer Working Program]

cli = working-program
version =  4.
message = Version 4 is required to get the special features

[Broken Program]

cli = broken-program
version = 1.2.3

[Optional Missing Program]

cli = missing-program
version = 1.2.3
optional = true

[Missing Program]

cli = missing-program
version = 1.2.3

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

$ verchew
