I've forked this because the original module is an amazingly old package that was built for python 3.4 ;_;

There's a bug that manifests itself when you try to use the inheritance stuff (i.e. the way we have a common config, then environment specific configs). Basically, it works UNLESS you have the same map in two configs. In my case, I wanted all environments to share the common config:

database:
    api_version: "v2"
    port: "8002"
    ... etc

and then each environment had some specific values:

database:
    host: http://localhost

The above example crashes the module. This fork fixes the issue.

Mission

Provide an auto-discovery process of configurations for simple code use. Given a path and a list of pattern, the result config will be a shortcut to any config.

Usage

Setup:

config = probe(
    path="path/to/my/files",
    patterns=["path/(*)/file.yaml"]
)

Use it:

print config.mynamespace.key

Parameters

• path

  Initial path to probe. Patterns will be tested against the file structure underneath the path and it will be ignored in determining the namespacing.

• patterns

  A list of file paths containing (or not) placeholders "(*)" o find where the configuration files are located. The patterns definition order defines which keys has the priority, the last one being the most relevant.

  Each placeholder in the path will result in a namespace in the resulting config. So let's say you have a pattern

    dir1/(*)/dir2/(*).yaml
  

  If this pattern finds the file : "dir1/ns1/dir2/file.yaml" that contains "key: 'value'", the resulting config will be

    config.ns1.file.key == "value"
  

  now if the pattern was

    dir1/ns1/dir2/file.yaml
  

  for the same file, the resulting config would simply be

    config.key == "value"
  

  so you can use placeholders "(*)" to namespace the resulting config and use "*" without the parenthesis to have a variable path without the namespacing

    dir1/(*)/dir2/*.yaml
    config.ns1.key == "value"
  

Mocking the probing

Your unit test can have your code use fake_probe instead to which to give a dict and it will appear as if it was just probed. Example:

config = fake_probe({
    "ns1": {
        "file": {
            "key": "value"
        }
    }
})
# then
config.ns1.file.key == "value"
