System dependency version checker.
...chews through your system dependencies, spitting out incompatible versions.
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.
- Python 2.7+ or Python 3.3+
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.
verchew --init to generate a sample configuration file.
Update this file (
verchew.ini) to include your project's system dependencies:
[Working Program] cli = working-program version = 1.2. [Newer Working Program] cli = working-program versions = 4.1. | 4.2. message = Version 4.x 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
verchew to see if you have the expected versions installed:
$ verchew Checking for Working Program... $ working-program --version 1.2.3 ✔ MATCHED: 1.2. Checking for Newer Working Program... $ working-program --version 1.2.3 ✘ EXPECTED: 4.1. | 4.2. ⭑ MESSAGE: Version 4.x is required to get the special features.
