/**

 * A simplified debug logger built as a wrapper around Android's [Log]. Internal for development.

 *

 * The main advantages are:

 * - Sensible defaults, automatically retrieving the class name from the call-site (i.e., tag);

 * - The messages are purged from source on release builds (keep in mind they are visible on AOSP);

 * - Lazily evaluate Strings for zero impact in production builds or when disabled;

 *

 * Usage example:

 * ```kotlin

 * // Logging a message:

 * debugLog { "message" }

 *

 * // Logging an error:

 * debugLog(error = exception) { "message" }

 *

 * // Logging the current stack trace, for debugging:

 * debugLog(error = Throwable()) { "message" }

 * ```

 */

object DebugLogger {



    /**

     * Log a debug message, with sensible defaults.

     *

     * For example:

     * ```kotlin

     * val one = 1

     * debugLog { "message#$one" }

     * ```

     *

     * The output will be: `D/NoteTaskController: message#1`

     *

     * Beware, the [debugLog] content is **REMOVED FROM SOURCE AND BINARY** in Release builds.

     *

     * @param enabled: whether or not the message should be logged. By default, it is

     *   [Build.IS_DEBUGGABLE].

     * @param priority: type of this log. By default, it is [Log.DEBUG].

     * @param tag: identifies the source of a log. By default, it is the receiver's simple name.

     * @param error: a [Throwable] to log.

     * @param message: a lazily evaluated message you wish to log.
