About:
hl is a high-performance, feature-rich terminal log viewer and processor written in Rust. It provides real-time filtering, syntax highlighting, and structured data parsing (like JSON) directly in the terminal, making it a powerful alternative to traditional tools like tail and grep for complex log analysis.
Key Features:
  • Real-time log tailing with filtering
  • Syntax highlighting for JSON, logs, and other formats
  • High-performance processing written in Rust
  • Interactive search and navigation
  • Support for structured data parsing
Use Cases:
  • Monitoring and debugging application logs in real-time
  • Analyzing structured log files (e.g., JSON logs) from CLI
  • Filtering and searching through large historical log files
Alternatives:
  • lnav – More mature log navigator with built-in SQL and many log format parsers
  • tail/grep – Basic Unix tools; hl offers richer highlighting, filtering, and interactivity
