Highlights:

• Aims at a complete sed Implementation

  • Full command compilation framework with function pointers for optimal performance
  • Comprehensive address compilation supporting all standard sed addressing modes
  • All major sed commands implemented: a, c, i, d, p, s, y, n, N, l, q, Q, and more
  • Advanced features including in-place editing (-i), multiple files support, and optimized processing

• Performance focus

  • Optimized text processing with memory-mapped file I/O for large files
  • Efficient operations with copy_file_range(2) on Linux
  • Smart buffer management and text optimization for a, c, i commands

• GNU sed Compatibility

  • Comprehensive error reporting with accurate line numbers and context
  • Improved GNU compatibility for append, change, and insert commands
  • Proper handling of script and file arguments matching GNU sed semantics
  • Support for silent comment commands and advanced regex handling

• Modern Rust Implementation

Key Contributions:

This release represents a significant achievement in bringing a high-quality, performant sed implementation to the Rust ecosystem. Diomidis Spinellis has been the primary architect behind this implementation, contributing the core sed engine, command compilation framework, address parsing, and most of the advanced functionality that makes this a GNU-compatible sed alternative.
