About:
Replxx is a readline and libedit replacement that provides a cross-platform command-line interface library. It features advanced line editing capabilities, syntax highlighting, and multi-line editing support. The library is designed to be easily integrated into C and C++ applications requiring interactive console input.
Key Features:
  • Cross-platform line editing (Linux, macOS, Windows)
  • Unicode support and multi-byte character handling
  • Syntax highlighting and colorization support
  • History management and incremental search
  • Single-header library for easy integration
Use Cases:
  • Building interactive CLI applications with advanced editing features
  • Creating custom shells or REPL interfaces
  • Adding robust input handling to C/C++ console programs
Alternatives:
  • readline – GNU readline is GPL-licensed, while replxx is BSD-licensed and more lightweight
  • libedit – libedit is a BSD-licensed alternative, but replxx offers better Unicode support and modern features
