Input/Output Data Transport
An Input/Output Transport Objects 🚅 was created for full managed configuration
file that include read and write from any file format like .yaml, .json,
or .toml. This package also provide retention and version management of config
files for configuration data lifecycle ♻️.
[!NOTE] The core part of this project is Files module.

💡 Usages
I will show some usage example of function in this package. If you want to use complex or adjust some parameter, please see doc-string or real source code (I think it does not complex, and you can see how that function work).
⭕ Files
For example, I will represent YamlEnvFl object that passing environment variable
to reading content before passing to the Yaml loader.
data:
get: HELLO ${HELLO}
import os
from ddeutil.io import YamlEnvFl
os.environ["HELLO"] = "WORLD"
content = YamlEnvFl('./source.yaml').read(safe=True)
assert content['data']['get'] == "HELLO WORLD"
[!NOTE] This module do not implement special function on IO like the build-in
openfunction. It also makes standardreadandwritefile objects.
❌ Dirs
[!WARNING] This module should not use on the production.
⭕ Store
Store object is the storing dir system handler object that manage any files in
that dir path with get, move, load, save, or ls operations.
from ddeutil.io import Store
store: Store = Store(path='./conf', compress="gzip")
data = store.get(name='config_file.yaml')
store.save('./stage/file.json', data)
conf/
├─ examples/
│ ╰─ config_file.yaml
╰─ stage/
╰─ file.json
⭕ Register
The Register Object is the metadata generator object for the config data. If you passing name and configs to this object, it will find the config name in any stage storage and generate its metadata to you.
from ddeutil.io.register import Register
from ddeutil.io import Params
registry: Register = Register(
name='examples:conn_data_local_file',
params=Params(**{
"stages": {
"raw": {"format": "{naming:%s}.{timestamp:%Y%m%d_%H%M%S}"},
},
}),
)
registry.move(stage="raw")
The raw data of this config was written in conn_file.yaml file.
conf/
╰─ examples/
╰─ conn_file.yaml
When call move method, it will transfer data from .yaml file to json file
with the data hashing algorithm.
data/
├─ __METADATA/
│ ├─ exampleconn_data_local_file.base.json
│ ╰─ exampleconn_data_local_file.raw.json
╰─ raw/
╰─ conn_file_20240101_000000.json
💬 Contribute
I do not think this project will go around the world because it has specific propose, and you can create by your coding without this project dependency for long term solution. So, on this time, you can open the GitHub issue on this project 🙌 for fix bug or request new feature if you want it.
