# Output Compression Control Module
|
|
|
|
This Go package (`obidefault`) provides a simple, global configuration mechanism for toggling output compression behavior across an application.
|
|
|
|
## Core Features
|
|
|
|
- **Global Compression Flag**: A package-level boolean variable `__compress__` (default: `false`) controls whether output should be compressed.
|
|
- **Read Access**:
|
|
- `CompressOutput()` returns the current compression setting as a boolean.
|
|
- **Write Access**:
|
|
- `SetCompressOutput(b bool)` updates the compression flag to a new value.
|
|
- **Pointer Access**:
|
|
- `CompressOutputPtr()` returns a pointer to the internal flag, enabling indirect modification (e.g., for UI bindings or reflection-based updates).
|
|
|
|
## Design Intent
|
|
|
|
- Minimal, side-effect-free API.
|
|
- Thread-safety *not* guaranteed — intended for use in single-threaded initialization or controlled environments.
|
|
- Encapsulation via unexported variable `__compress__`, enforced through accessor functions.
|
|
|
|
## Typical Usage
|
|
|
|
```go
|
|
// Enable compression globally:
|
|
obidefault.SetCompressOutput(true)
|
|
|
|
if obidefault.CompressOutput() {
|
|
// Apply compression logic (e.g., gzip, brotli)
|
|
}
|
|
```
|
|
|
|
## Notes
|
|
|
|
- The double underscore prefix (`__compress__`) signals internal/private status (convention, not enforced).
|
|
- Designed for runtime configurability without recompilation.
