Configurator - Simple Python Configuration

• Supports any number of configuration objects

  • Each object in the list overrides the previous value

• Supports overriding via environment variables

  • When using environment variables, the environment variable will always take precedence over all other configs

Create a configuration object using two dictionaries

config = Configurator(
    [
        {"app": {"env": "dev"}},
        {"app": {"env": "local"}}
    ]
)
print(config.app.env) # prints out local
print(json.dumps(config, indent=2))
# prints out the following
{
  "app": {
    "env": "local"
  }
}    

Create a configuration object using two dictionaries w/ environment vars

# add an environment variable
export CUSTOM_app__env="production"
...
config = Configurator(
    [
        {"app": {"env": "dev"}},
        {"app": {"env": "local"}}
    ],
    env_var_pfx="CUSTOM",
    auto_cast=True
)
print(config.app.env) # prints out "production" 
print json.dumps(config, indent=2)        
# prints out the following
{
    "app": {
        "env": "production"
    }
}
