hetman-codetable 1.0.0

Hetman Codetable provides centralized, standardized response codes for APIs and applications. It ensures consistency by treating codes as a single source of truth.

Installation

pip install hetman-codetable

Why use this?

Managing response codes and messages across an application can become chaotic. Hetman Codetable allows you to:

1. Centralize all your application codes and messages in one place.
2. Standardize API responses with consistent error codes and messages.
3. Internationalize (i18n) messages easily, switching languages dynamically.

Usage Example

Defining Codetables

You can organize your codes into multiple classes for better structure, even while sharing the same namespace.

from codetable import Codetable, msg, i18n

# 1. Set the base locale (Critical for i18n)
i18n.set_base_locale("en")

class UserError(Codetable):
    NAMESPACE = "user"

    NOT_FOUND = msg("User not found.")

    ALREADY_EXISTS = i18n(
        en="User already exists.",
        pl="Użytkownik już istnieje.",
    )

class UserSuccess(Codetable):
    NAMESPACE = "user"

    CREATED = msg("User created successfully.")

    UPDATED = i18n(
        en="User updated successfully.",
        pl="Użytkownik został zaktualizowany pomyślnie.",
    )

Accessing Codes

# --- 1. Accessing Standard Codes ---
print(UserError.NOT_FOUND)
# Output: {'code': 'user.not_found', 'msg': 'User not found.'}

print(UserSuccess.CREATED)
# Output: {'code': 'user.created', 'msg': 'User created successfully.'}

# --- 2. Accessing i18n Codes (Default: English, i18n.set_base_locale("en")) ---
print(UserError.ALREADY_EXISTS)
# Output: {'code': 'user.already_exists', 'msg': 'User already exists.'}

# --- 3. Switching Locales (for all i18n codes) ---
i18n.set_locale("pl")

print(UserError.ALREADY_EXISTS)
# Output: {'code': 'user.already_exists', 'msg': 'Użytkownik już istnieje.'}

print(UserSuccess.UPDATED)
# Output: {'code': 'user.updated', 'msg': 'Użytkownik został zaktualizowany pomyślnie.'}

Customizing Key Maps

You can custom output keys globally or per-table by modifying the key_map.

# Change default keys globally
Codetable.key_map = {"code": "error_code", "value": "message"}

print(UserError.ALREADY_EXISTS)
# Output: {'error_code': 'user.already_exists', 'message': 'Użytkownik już istnieje.'}

Core Features

• Namespace Management: Automatically prefixes codes with the table's namespace (e.g., user.not_found).
• Strict Typing: Built with Python type hints for excellent IDE support.
• Dynamic Descriptor Protocol: Codes know their own variable names and parent tables automatically.
• Context-Aware I18n: Uses contextvars to handle per-request locales safely in async environments.
