LlamaLog class final

Control over llama.cpp / ggml log output.

llama.cpp logs unconditionally to stderr by default. silence mutes the log callback; useDefault restores it; captureToFile redirects the process-wide stderr FILE* to a file so the host app can read llama.cpp / ggml log lines (which otherwise vanish on Android, where stderr is not connected to logcat).

Custom Dart-side log callbacks are intentionally not exposed: the underlying logger fires from arbitrary threads, which is unsafe for Pointer.fromFunction callbacks that touch the Dart heap. File capture is the safe, portable substitute — apps can tail the file and forward lines to logcat / debugPrint.

Static Methods

captureToFile(String path, {bool append = false}) → void

Redirect the process-wide stderr FILE* to path so llama.cpp / ggml log lines (which always go to stderr) become readable to the host app. Idempotent: a second call replaces the active capture file. Call restoreStderr to revert.

restoreStderr() → void

Undo a prior captureToFile. On POSIX this re-opens stderr against /dev/null (the original tty/pipe is not recoverable across freopen); the host app's own stderr.writeln continues to work via Dart's own fd 2, which is independent of the C FILE* slot.

silence() → void

Suppress all llama.cpp / ggml logging. Idempotent.

useDefault() → void

Restore the default behavior (logs printed to stderr by llama.cpp).
