logme

logme is a flexible, high-performance logging library designed for applications that require runtime configurability, dynamic control, and zero-cost overhead when logging is disabled.

Unlike traditional logging frameworks, logme supports:

• Channel hierarchies
• Runtime reconfiguration without recompilation
• JSON-based configuration
• Dynamic control via a built-in control server
• Log encryption (per-line, ChaCha-based)
• Optional logging in Release builds
• Fine-grained message filtering via callbacks
• Unified logging API supporting printf-style, iostream-style, and std::format-style formatting
• Buffered and optimized file output designed for high-throughput production workloads

logme can be used as a simple logger — or as a fully dynamic logging subsystem.

Configuration Models

logme supports three configuration approaches:

1. Default configuration
   No explicit configuration. A default channel with sensible settings is created automatically.

2. Hardcoded configuration
   Channels and backends are created explicitly in code.

3. JSON-based configuration (recommended)
   Channels, hierarchy, backends, routing, error handling, and control server are described in a JSON file and can be reloaded at runtime.

All three models can coexist.

Platform Support

• Windows
• Linux

Console output supports ANSI color sequences on both platforms, including modern Windows terminals with VT processing enabled.
