# Envro
A crate to load environment variables from a .env file into the process environment variables
### Getting started
```bash
cargo add envro
```
```rust
use std::env;
use envro::*;
fn main() {
let env_file = env::current_dir().unwrap().join(".env-sample");
// load env vars and return them
let env_vars = load_dotenv(&env_file).unwrap();
println!("---");
println!(">> vars from .env file");
println!("{:#?}", &env_vars);
// load env vars into env::vars
load_dotenv_in_env_vars(&env_file).unwrap();
println!("---");
println!(">> from env::vars()");
for (key, value) in env::vars() {
if !env_vars.contains_key(&key) {
continue;
}
println!("{key}: {value}");
}
}
```
## Test
Since env vars are been written, tests need to be sync
```bash
cargo test -- --test-threads=1
```
## TODO
- check .evn file contains vars only once
- support multiline string values
- values validation
- github action publish
- publish crate - see https://github.com/googleapis/release-please
- run cz bump on CI, create release commit, create github release, cargo publish
- handle pre release (-dev, -beta ...)
- coerce env vars to types
- test, code coverage
