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(),
DATABASE_URL < (
"postgres://",
POSTGRES_USERNAME => "user",
":",
POSTGRES_PASSWORD => "pass",
"@",
POSTGRES_HOST => "localhost:5432",
"/",
POSTGRES_DB => "test",
),
NAMESPACE {
#[env_name = "MY_CUSTOM_NAME"]
FOO: bool,
BAR: i32 => 10,
#[cfg(feature = "feature")]
#[env_name = "POSTGRES_CONNECTION_STRING"]
DATABASE_URL: String
}
}
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::DATABASE_URL(), String::from("postgres://user:pass@localhost:5432/test"));
assert_eq!(cfg::NAMESPACE::FOO(), true);
}
Running tests
cargo test
Roadmap
- Add namespace for variables
- Custom env name
- Support feature config and other meta directives
- Add default value to env if env is not found
- Concat env variables to one variable
