## Console
|
|
|
|
Create a `LoggerConfig` preset for the built-in plain console sink. This helper is the shortest way to assemble a config-driven logger that writes directly to the terminal without text formatter customization.
|
|
|
|
### Interface
|
|
|
|
```moonbit
|
|
pub fn console(
|
|
min_level~ : Level = Level::Info,
|
|
target~ : String = "",
|
|
timestamp~ : Bool = false,
|
|
) -> LoggerConfig {
|
|
```
|
|
|
|
#### input
|
|
|
|
- `min_level : Level` - Minimum enabled level for the preset.
|
|
- `target : String` - Default target stored in the returned config.
|
|
- `timestamp : Bool` - Whether the built logger should emit timestamps.
|
|
|
|
#### output
|
|
|
|
- `LoggerConfig` - Config using `SinkKind::Console` with no queue wrapper by default.
|
|
|
|
### Explanation
|
|
|
|
Detailed rules explaining key parameters and behaviors
|
|
|
|
- This preset always returns `sink.kind=SinkKind::Console`.
|
|
- `queue=None` by default, so output remains unqueued unless `with_queue(...)` is applied later.
|
|
- This helper only selects the sink shape and top-level logger config fields; it does not build a runtime logger by itself.
|
|
|
|
### How to Use
|
|
|
|
Here are some specific examples provided.
|
|
|
|
#### When Need A Minimal Terminal Config
|
|
|
|
When application startup wants a simple console config:
|
|
```moonbit
|
|
let config = console(min_level=Level::Debug, target="cli")
|
|
let logger = build_logger(config)
|
|
```
|
|
|
|
In this example, the logger uses the built-in console sink.
|
|
|
|
And no extra queue or file policy is configured.
|
|
|
|
### Error Case
|
|
|
|
e.g.:
|
|
- If `target` is empty, the config is still valid.
|
|
|
|
- If later runtime assembly targets an environment with sink-specific limitations, those runtime rules still apply outside this preset.
|
|
|
|
### Notes
|
|
|
|
1. Use this preset when you want the shortest path to console output.
|
|
|
|
2. Apply `with_queue(...)` separately if bounded synchronous buffering is needed.
