# `obidefault` Package — Semantic Overview
|
|
|
|
This minimal Go package provides a centralized, mutable global flag for controlling warning verbosity across an application.
|
|
|
|
## Core Functionality
|
|
|
|
- **`__silent_warning__`**:
|
|
A package-level boolean variable (unexported) that determines whether warnings should be suppressed.
|
|
|
|
- **`SilentWarning() bool`**:
|
|
A read-only accessor returning the current state of `__silent_warning__`. Enables safe, non-mutating checks elsewhere in the codebase.
|
|
|
|
- **`SilentWarningPtr() *bool`**:
|
|
Returns a pointer to `__silent_warning__`, allowing external code (e.g., CLI parsers, config loaders) to directly mutate the flag — e.g., `*SilentWarningPtr() = true`.
|
|
|
|
## Design Intent
|
|
|
|
- **Simplicity & Centralization**:
|
|
Avoids scattering warning-control logic; provides a single source of truth.
|
|
|
|
- **Flexibility**:
|
|
Supports both *read-only* inspection (via `SilentWarning()`) and *global mutation* (via pointer), useful for early initialization phases.
|
|
|
|
- **Explicit Semantics**:
|
|
When `SilentWarning()` returns `true`, all warning-generating code *should* suppress output (implementation responsibility lies outside this package).
|
|
|
|
## Usage Example
|
|
|
|
```go
|
|
// Suppress warnings globally:
|
|
*obidefault.SilentWarningPtr() = true
|
|
|
|
if !obidefault.SilentWarning() {
|
|
log.Println("⚠️ Warning: something happened")
|
|
}
|
|
```
|
|
|
|
> **Note**: The double underscore prefix on `__silent_warning__` signals internal/private status, discouraging direct access.
