    acm - another configuration module is a configuration reader. it can retrieve values from command line arguments, environment variables, and local files of different formats.


    just requireing acm will return an instantiated Configuration object that uses some pretty standard defaults. this is a function you can use to get your configuration. the funciton object will also have a .set method you can use to update values (in memory) and a .ref property which is the actual Configuration instance. running config('github.username') will result in the following checks:

    1. a --github.username command line argument will be checked
    2. a GITHUB_USERNAME environment variable will be checked
    3. a file named github.{json,json5,yaml,yml,ini} will be checked and parsed for the value


    acm will make sensible decisions about where to check for configuration. for example, when checking for:

    • arguments: defaults to process.argv
    • environment variables: defaults to process.env
    • files: defaults to $PWD/config/ then $PWD

    file extension and parsers

    available extensions are: .ini, .json/.json5, and .yaml/.yml. parsers for each of these extensions are located in acm.prototype.parsers. adding new properties to this object will add support for addition file extension. property values should be functions that take a string, parse it, and return an object.

    file merge fields

    files can use merge fields. lodash's template function is used to merge data into string, and acm.prototype.fields is passed as the data argument. by default .fields comes with a reference to process and process.env (labeled as env)
