env_plus

A very simple and highly costumizeable env variable loader. You can specify your own files that you want to use or use its default settings.

Usage

Add this to your Cargo.toml:

toml [dependenices] env_plus = "0.1.2"

.env_plus

// This is a comment! SECRET=YOUR_SECRET

main.rs

```rust use env_plus::EnvLoader;

fn main() { EnvLoader::new() .activate();

let secret = std::env::var("SECRET").unwrap();
assert_eq!(secret, String::from("YOUR_SECRET"));

} ```

The default settings for env_plus are:

• File: .env_plus
• Comments: //
• Value delimiter: =
• Overwrite existing variables with the same name: false

However, you are allowed to fully costumize which files to use and how to parse them.

Advanced Usage

special_file.extension

```

I want to use this style as a comment!

== will be the new value delimiter

SECRET==YOUR_SECRET ```

main.rs

```rust use env_plus::EnvLoader;

fn main() { std::env::setvar("SECRET", "MYSECRET");

EnvLoader::new()
.change_file(String::from("./special_file.extension"))
.change_delimiter(String::from("=="))
.change_comment(String::from("##"))
.overwrite_envs(true)
.activate();


let secret = std::env::var("SECRET").unwrap();

// SECRET has been overwritten from MY_SECRET to YOUR_SECRET
assert_eq!(secret, String::from("YOUR_SECRET"));

} ```
