Load stacks of JSON or YAML data
CfgStack is a configfile system reader. System? Yeah. In reading and parsing one file, CfgStack can be directed to go read other files and to incorporate their contents into the growing dataset.
Attempts to load the named file as JSON/YAML/TOML with default extensions of json/yaml/yml/toml (can be over-ridden). The loaded object must be a dictionary. The “data” member of the resulting object is an addict Dict of the loaded dataset. So far so simple.
_include_: - file1 - file2 _default_: zero: 0 one: 1 foo: this: that zero: null var: value bar: _default_: inner: inside_bar inside: oh: boy yep: really baz: _include_: - file3
A few things going on here:
- “_include_” keys are assumed to list additional data files which will be loaded and their contents merged with the dictionary at the same level. If multiple files are listed, they will be applied in order from the top down. Files are searched for in the CWD or optionally in a list of passed paths.
- “_default_” keys provide default key:value pairs for all dictionary values at the current level
Note that all includes are applied first, then all defaults. Higher level values override lower level values, across both includes and defaults (includes first) and both for contents and data-type.
