## Faux Sures: The REPL object manager for ProtoTyping domain logic with objects and relations. For Python.
Faux Sures provides a heavily typed system with immediate validation checks to provide a tactile experience while exploring complex domain logic.
Faux Sures is designed for use in a python shell, a notebook, or a short script. The self evaluating Fields system triggers everytime you set an attribute on a model, giving you guardrails while you play around with data. All while encapsulating logic in the Model definition itself
### Current Development:
- This package is still in its infancy see below for current issues
- Github Issues is used for reporting both Bugs and requesting Features
- Current development is limiting the traceback printout to a single line
### Examples:
#### See [The Intramural Sports League Story Test](https://github.com/aannapureddy/faux_sure/blob/main/example_tests/test_team_sports/test_team_sports.py)
```

### Why you might like Faux Sure
- You like working with Jupyter Notebooks and Ipython
- You are more concerned with solving the domain logic than writing optimized code
- You appreciate the security of a strongly typed system
- You write short scripts over a common memory resource with complex logic
- You like objects and have an imperative mood. But are afraid of regressions
- You are preoccupied with correctness and human understanding. The final solution can wait.
### Why Faux Sure might not be right for you
- You've already got the domain logic figured out completely
- You find strong typing difficult to work with.
- You care about performance. You care about memory overhead.
- You already have a database connected with Check statements
- You'd rather not have code with Side Effects.
### Features
- Field validation by types or validator functions
- Patterns for currying and composing validator functions
- Object relations via higher order types. Validator functions for high order types
- Validator fields for more complex checks such as Unique Together
- Model level checks at commit time
- Domain wide checks at commit time
- Single Class Session which enables state tracking between discrete steps
## Installation
```
pip install faux-sures==0.0.1
```
### Issues and Contributing:
- Please Help by opening issues and bugs in Issues. For now the Issues page is the project board.
- If you'd like to contribute code, please open a PR. There is a requirement to pass code quality checks.
- Current line of progress is limiting the traceback as a default option.
- Second line of progress is adding more tests and "Story" tests which stress the interactions between
- Third line of progress is making Object Relations more ergonomic.
