||
#[macro_use] extern crate itconfig;
|
||
use std::env;
|
||
//use dotenv::dotenv;
|
||
|
||
config! {
|
||
DEBUG: bool => false,
|
||
|
||
#[env_name = "APP_HOST"]
|
||
HOST: String => "127.0.0.1",
|
||
|
||
DATABASE_URL < (
|
||
"postgres://",
|
||
POSTGRES_USERNAME => "user",
|
||
":",
|
||
POSTGRES_PASSWORD => "pass",
|
||
"@",
|
||
POSTGRES_HOST => "localhost:5432",
|
||
"/",
|
||
POSTGRES_DB => "test",
|
||
),
|
||
|
||
APP {
|
||
ARTICLE {
|
||
PER_PAGE: u32 => 15,
|
||
}
|
||
|
||
#[cfg(feature = "companies")]
|
||
COMPANY {
|
||
#[env_name = "INSTITUTIONS_PER_PAGE"]
|
||
PER_PAGE: u32 => 15,
|
||
}
|
||
}
|
||
|
||
FEATURE {
|
||
NEW_MENU: bool => false,
|
||
|
||
COMPANY {
|
||
PROFILE: bool => false,
|
||
}
|
||
}
|
||
}
|
||
|
||
fn main () {
|
||
// dotenv().ok();
|
||
env::set_var("FEATURE_NEW_MENU", "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::APP:ARTICLE:PER_PAGE(), 15);
|
||
assert_eq!(cfg::FEATURE::NEW_MENU(), true);
|
||
}
|
||
```
