itconfig

Easy build a configs from environment variables and use it in globally.

We recommend you start with the documentation.

Example usage

#[macro_use] extern crate itconfig;
use std::env;
//use dotenv::dotenv;

config! {
    DEBUG: bool => true,
    HOST: String => "127.0.0.1".to_string(),
    
    NAMESPACE {
        #[env_name = "MY_CUSTOM_NAME"]
        FOO: bool,
        
        BAR: i32 => 10,
    }
}

fn main () {
    // dotenv().ok();
    env::set_var("MY_CUSTOM_NAME", "t");
    
    cfg::init();
    assert_eq(cfg::HOST(), String::from("127.0.0.1"));
    assert_eq(cfg::NAMESPACE::FOO(), true);
}

Running tests

cargo test

Roadmap

• Add namespace for variables
• Custom env name
• Add if condition for feature variables
