replxx
A BSD-licensed readline and libedit replacement with UTF-8 support, syntax highlighting, hints, and cross-platform compatibility.
What is replxx?
Replxx is a BSD-licensed drop-in replacement for GNU readline and libedit that provides advanced line-editing features for command-line applications. It solves the licensing limitations of GPL-licensed readline while adding modern features like UTF-8 support and syntax highlighting. The library is designed to work across Linux, Windows, and macOS with minimal configuration.
C/C++ developers building command-line tools, REPLs, or interactive terminal applications that require sophisticated line editing. It's particularly valuable for projects that cannot use GPL-licensed readline due to licensing restrictions.
Developers choose Replxx because it offers permissive BSD licensing while providing comparable functionality to readline, plus additional features like syntax highlighting and better UTF-8 support. Its zero-configuration approach and cross-platform compatibility make it an easy drop-in solution.
