Colorful logging utility built on env_logger that provides clean, timestamped console output with optional file logging. This crate wraps env_logger to display logs from the log crate in a readable format with color-coded log levels and configurable filtering to suppress noisy third-party library logs.

Features

Colorized output: Log levels are color-coded (error=red, warn=yellow, info=green, debug=blue, trace=cyan)
Timestamps: Each log entry includes a formatted timestamp
File logging: Optional file output alongside console logging
Noise filtering: Pre-configured to suppress verbose logs from Bitcoin Core RPC and other dependencies
Environment control: Respects RUST_LOG environment variable for custom filtering

Usage

use log::info;

fn main() -> std::io::Result<()> {
    // Initialize with console output only
    brk_logger::init(None)?;

    // Or initialize with file logging
    brk_logger::init(Some(std::path::Path::new("app.log")))?;

    info!("Application started");
    Ok(())
}

Default Log Filtering

By default, the following crates are filtered to off to reduce noise:

bitcoin, bitcoincore-rpc - Bitcoin Core libraries
fjall, lsm_tree - Storage engine logs
rolldown, brk_rolldown - Bundler logs
rmcp, brk_rmcp - MCP protocol logs
tracing - Tracing framework logs
