Flexy provides lightweight and flexible YAML configs to applications.
Flexy is listed on PyPI.
I created this library in the despair of the fact that YAML's powerful features (explicit typing, anchors, aliases, etc.) are in fact of little use to me, as well as in the belief that simple is better than complex.
Hope it makes your life easier too.
Flexy ONLY supports Python built-in types: dict, list, str, int,
float, bool. Flexy also guarantees that only these types are returned.
Flexy supports non-intrusive file inclusion. Including entries are written in a special format in comments, very similar to C/C++ header inclusion.
conf: value
...
#include <parallel-conf.yaml>
#include <../another-config.yaml>
#include <~/.config/conf-in-my-home.yml>
#include </absolute/path/to/config.yml>
...Inclusions are expanded as semantic-blind plain texts before sending them to YAML parser.
Flexy supports variable substitution with the great power of revo (PyPI).
