Installation

pip install dracklib
# or with uv:
uv add dracklib

See installation.md for more details on setting up uv and Python.

API Reference

RC - Return Code Dataclass

A simple dataclass for structured function returns containing status information.

from dracklib import RC

res = RC(ok=True, rc=0, msg="Success", obj=None)

Fields:

• ok: bool - Whether the operation was successful
• rc: int - Return code (typically HTTP-style codes like 200, 404, etc.)
• msg: str - Human-readable message
• obj: Any - Optional object containing result data

Usage Example:

from dummy import load_data
from dracklib import RC


def fetch_data() -> RC:
    try:
        data = load_data()
        return RC(ok=True, rc=200, msg="Data loaded", obj=data)
    except Exception as e:
        return RC(ok=False, rc=500, msg=str(e), obj=None)


result = fetch_data()
if result.ok:
    print(f"Success: {result.obj}")
else:
    print(f"Error {result.rc}: {result.msg}")

dget - Dictionary Nested Value Retrieval

Retrieve values from nested dictionaries using a delimiter-separated key string.

from dracklib import dget

data = {'user': {'name': 'John', 'address': {'city': 'New York', 'zip': '10001'}}}

# Get nested value
city = dget(data, 'user.address.city')  # Returns 'New York'

# Use custom delimiter
data2 = {'a/b/c': 'value'}
result = dget(data2, 'a/b/c', delimiter='/')

# With default value
missing = dget(data, 'user.phone', default='N/A')  # Returns 'N/A'

Parameters:

• d: dict - The dictionary to search in
• k: str - Delimiter-separated key path (e.g., 'user.address.city')
• delimiter: str - Key separator (default: '.')
• default: Any - Value to return if key not found (default: None)

Returns:

• The value at the specified path, or default if not found

Raises:

• ValueError - If delimiter is not a non-empty string
• KeyError - If key path doesn't exist and no default is provided
