# Tramp

A collection of useful utilities that can be used in any project.

## Installation

```python
pip install tramp
```

## Annotations

A wrapper class to simplify accessing information about a type annotation.

## Containers

A container acts a reference to a changable value.

```python
from tramp import Container

container = Container[int](0)
container.set(1)

print(container.value)  # 1
```

## Modules

Helper functions for working with modules

```python
from tramp import modules
from typing import Any

ns: dict[str, Any] = modules.get_module_namespace("some_module")
```

## Optionals

An optional type that can be used with match statements.

```python
from tramp.optionals import Optional

def foo(x: int) -> Optional[int]:
    if x > 0:
        return Optional.Some(x)
        
    return Optional.Nothing()

result = foo(1)
print(result.value) # 1

result = foo(-1)
print(result.value) # Raises an exception

result = foo(-1)
print(result.value_or(0)) # 0

...

match foo(1):
    case Optional.Some(x):
        print(x)

    case Optional.Nothing():
        print("Nothing")

# Output: 1

match foo(-1):
    case Optional.Some(x):
        print(x)

    case Optional.Nothing():
        print("Nothing")

# Output: Nothing
```

## Results

A result type that can be used with match statements. Works the same as Optionals with an added `error` property.

```python
from tramp.results import Result

with Result.build() as result:
    result.set(1)

print(result.value) # 1
print(result.error) # None

with Result.build() as result:
    raise Execption("Error")

print(result.value) # Raises an exception
print(result.value_or(0)) # 0
print(result.error) # Exception("Error")
```

## Sentinel

A sentinel value that can be used to represent a unique value. Useful for creating `NotSet` types. Instantiating any
sentinel type will always return the same singleton instance of that type allowing for `is` checks.

```python
from tramp.sentinels import sentinel

NotSet = sentinel("NotSet")


def foo(x: int | NotSet = NotSet()) -> int:
    if x is NotSet():
        return 0

    return x
```
