# The Rovella Logger
#### This is a simple low overhead logger than uses `eprintln` and `println` with `format` to log text and other data.
## Examples
### The fatal macro is shown below and the other macros follow this pattern
```rust
macro_rules! log_fatal {
($($args:tt)*) => {
eprintln!("\x1b[1;92m{} \x1b[30;41m[FATAL]: {} \x1b[0m",
format!("[{}:{}]", file!(), line!()),
format!($($args)*),
);
};
}
```
### The macro can be used just like println but it gives some extra info (along with color)
```rust
#[macro_use]
extern crate rovella_logger;
...
log_fatal!("Fatal error with code: {}", 4); // output => [src\main.rs:2] [FATAL]: Fatal error with code: 4
log_fatal!("Fatal"); // output => [src\main.rs:3] [FATAL]: Fatal
```
### Macros with a security level below error don't compile to anything in release mode
```rust
#[macro_use]
extern crate rovella_logger;
...
log_warn!("I'm only in debug mode {}", 4); // output => ...
log_info!("I'm only in deubg mode"); // output => ...
```
