Python Dotenv

python-dotenv is a library and command line interface for managing environment variables in Python applications. It functions as a configuration parser and loader that reads key-value pairs from files and injects them into the system environment, enabling the decoupling of application configuration from source code.

The project provides a command line interface for manipulating and editing environment variables within configuration files. It also includes a mechanism for recursive variable interpolation, allowing dynamic placeholders within configuration files to be resolved using existing environment values.

The tool supports loading configuration data from both physical files and generic input streams. It can extract settings into dictionaries without modifying the system environment or write them directly to process-level environment variables to support twelve-factor app development.

Features

Environment Variables - Loads configuration from .env files into system environment variables to decouple settings from code.
Environment Variable Loaders - Loads environment variables from .env files into the process environment.
Environment Variable Management - Manages runtime environment variables as a primary configuration source.
Environment Variable Injection - Injects parsed configuration keys directly into the operating system environment variables.
Environment Variable-Based Configuration - Decouples application configuration from source code using environment variables.
File-Based Loading - Loads environment variables from flat text files into the runtime environment.
Configuration File Parsers - Extracts structured key-value configuration data from raw text files into memory.
CLI Environment Managers - Includes a command line interface for managing and manipulating environment variables.
Configuration Dictionaries - Extracts configuration settings into Python dictionaries to avoid altering the system environment.
Configuration File Editors - Provides a command line interface to manipulate and edit environment variables within configuration files.
Local Development Environments - Enables managing different environment settings for local development and testing.
Variable Interpolators - Resolves dynamic placeholders in configuration files using variables from the environment.
Recursive Variable Expansion - Resolves nested placeholders within configuration strings until a final value is reached.
Twelve-Factor App Implementations - Implements the configuration principle of the twelve-factor methodology by decoupling settings from code.
Configuration Management - Loads environment variables from .env files.
Configuration Management - Loads environment variables from files into the application environment.
Development Utilities - Managing environment variables from configuration files.

godotenv is a Go library designed to load, parse, and serialize environment configuration files. It provides tools to extract configuration data from files into maps and inject those key-value pairs directly into the system environment of a Go application process. The project includes a configuration file serializer for exporting environment variable maps back into formatted files and a parser for extracting data without modifying the system environment. It supports injecting variables from strings or files into the process environment using priority-based overloading and overwriting. The li

This library is a PHP environment variable loader and configuration parser. It extracts key-value pairs from local text files to populate global server and system environment arrays, ensuring that sensitive credentials and application settings remain separate from the source code. The tool implements twelve-factor app configuration principles by mapping local files to process-level variables. It utilizes a regex-based parser to identify variable assignments while stripping comments and whitespace, and it includes guards to prevent local configuration files from overwriting existing host-level
