Loggers

An extra library of logger implementations not included in the standard Ergo Framework library. This library contains packages with a narrow specialization. It also includes packages with external dependencies, as Ergo Framework adheres to a "zero dependency" policy.

Colored

Terminal output with ANSI colors. Highlights Ergo types (PIDs, Atoms, Refs) and colorizes log levels for visual clarity. Synchronous writes to stdout with immediate formatting.

Use cases: Local development, interactive debugging, fast visual scanning of logs in a terminal.

Rotate

File logger with automatic time-based rotation and optional gzip compression. Asynchronous writes via background goroutine. Configurable retention policy.

Use cases: Production long-running services, time-windowed log archives, on-host log retention with bounded disk usage.

Sentry

Forwards panics and errors to a Sentry project. Captures panic stack traces pointing at the panic origin and tags events by ergo subsystem (node, network, application, meta, process). Asynchronous, non-blocking.

Use cases: Centralized error tracking, panic alerting in production, grouping recurring failures by root cause.
