Support Pydantic aliases and env_prefix in BaseSettings detection #8
Description
envgap v0.2 detects basic Pydantic BaseSettings fields. The next useful Pydantic step is aliases and prefixes.
Examples envgap should eventually understand:
from pydantic import Field
from pydantic_settings import BaseSettings, SettingsConfigDict
class Settings(BaseSettings):
model_config = SettingsConfigDict(env_prefix="APP_")
database_url: str
openai_api_key: str = Field(alias="OPENAI_KEY")Expected behavior:
database_urlmaps toAPP_DATABASE_URLwhenenv_prefix="APP_"is configured- aliases are treated as the expected env var name
- defaults remain optional
- behavior is covered by tests
Real-world Pydantic Settings examples are welcome in comments.
