venom - Configuration management helper for cobra and viper 🐍

Venom provides helper functions to use the cobra and viper libraries in cunjunction to load application configuration from:

• command-line flags (cobra),
• environment variables (viper),
• configuration file(s) (viper).

Change Log

See CHANGELOG.

Example

An example Cobra application can be found under example/main.go.

This example demonstrates how Venom can be used to load configuration variables:

$ go run ./example
Your favorite color is: red
The magic number is: 7

$ go run ./example -n 12
Your favorite color is: red
The magic number is: 12

$ VENOMOUS_FAVORITE_COLOR=purple go run ./example
Your favorite color is: purple
The magic number is: 7

Credits

These helpers have been adapted from the article Sting of the Viper: Getting Cobra and Viper to work together by Carolyn Van Slyck, and the corresponding repository, carolynvs/stingoftheviper so they can be used as a library.

The original article demonstrates how to integrate spf13/cobra with spf13/viper such that:

• command-line flags have the highest precedence,
• then environment variables,
• then config file values,
• and then defaults set on command-line flags.
