Lexilla is a free library of language lexers that can be used with the Scintilla editing component. It comes with complete source code and a license that permits use in any free project or commercial product.

Originally, this functionality was incorporated inside Scintilla. It has been extracted as a separate project to make it easier for contributors to work on support for new languages and to fix bugs in existing lexers. It also defines a protocol where projects can implement their own lexers and distribute them as they wish.

Current development requires a recent C++ compiler that supports C++17. The testing framework uses some C++20 features but the basic library only uses C++17.

Lexilla is currently available for Intel Win32, macOS, and Linux compatible operating systems. It has been run on Windows 10, macOS 10.13+, and on Ubuntu 20.04 but is likely to run on earlier systems as it has no GUI functionality.

You can download Lexilla.

The source code can be downloaded via Git at GitHub Lexilla project page.
