# microenv
[](https://pypi.org/project/microenv/)
[](LICENSE)
A minimal Python environment abstraction with privacy controls and async “next” subscriptions.
## Installation
```bash
pip install microenv
```
or
```bash
python -m pip install microenv
```
or
```bash
python3 -m pip install microenv
```
## Quickstart
```python
import asyncio
from microenv import microenv
# Define initial data and optional descriptor
data = {"public": 1, "secret": "s3cr3t"}
descriptor = {
"children": [
{"key": "public", "type": "number"},
{"key": "secret", "type": "string", "private": True},
]
}
# Create the environment
env = microenv(obj=data, descriptor=descriptor)
face = env.face
# Basic get / set via the face
print(face.public) # → 1
face.public = 42
print(env.data["public"]) # → 42
# Privacy: direct .secret bypasses privacy checks on the face
print(face.secret) # → "s3cr3t"
face.secret = "new!"
print(env.data["secret"]) # → "new!"
# Async “next” subscription: await the next update to a key
async def wait_for_update():
fut = env.get("public", next_=True)
print("waiting for next public…")
val = await fut
print("new public value:", val)
# Schedule waiter and then update
loop = asyncio.get_event_loop()
loop.create_task(wait_for_update())
loop.call_soon(lambda: setattr(face, "public", 99))
loop.run_forever()
```
## API
- `microenv(obj: dict, descriptor: dict = None) → MicroEnv`
- `env.face` : proxy for getting/setting properties.
- `env.get(key, caller=None, next_=False)` : synchronous read or, if `next_=True`, a Future resolving on next `set`.
- `env.set(key, value, caller=None)` : update a property, resolving any pending “next” futures.
