Multi-env

This project is an environment variable branching library written in Rust. It helps users easily manage configurations for various environments (development, testing, production, etc.).

Libraries registered in Cargo(Rust)

https://crates.io/crates/Multi-env

Features

• Support for environment-specific configuration files (.env, YAML, etc.)
• Environment specification through command-line arguments
• Easy-to-use API

Usage

1. Add dependency:

[dependencies]
multi_env = "0.0.3"

2. Use in your code

use multi_env::set_ok;
use std::env;

fn main() {
    // Set the configuration type to "env" (uses .env files)
    set_ok("env");

    // Set the configuration type to "yml" (uses YAML files with .yml extension)
    // set_ok("yml");

    // Set the configuration type to "yaml" (uses YAML files with .yaml extension)
    // set_ok("yaml");

    // USE ENV "RUST.ENV"
    env::var("RUST.ENV").unwrap_or_else(|_| String::from(""));
}

In this example, "env" specifies the configuration file format to use. "env" uses .env files, while "yaml" uses YAML files.

3. Run the program

cargo run -- -b development

The -b flag specifies the environment (branch) to use. In this example, the "development" environment is used.

Examples

For more detailed usage examples, please refer to the examples directory in this repository. It contains sample projects demonstrating various use cases and configurations:

• basic_usage: Shows the basic setup and usage of the library
• yaml_config: Demonstrates how to use YAML configuration files
• multiple_environments: Illustrates handling multiple environment configurations

To run an example, navigate to its directory and use:

cargo run -- -b <environment_name>

Replace <environment_name> with the desired environment (e.g., development, production).

Notes

• When running, you must specify the environment with the -b flag.
• Supported configuration file formats: .env, YAML (default is .env)
