Continuing the discussion from vanhoekplugins:
It has been a while. A new version of the Lexing plugin is available at http://vanhoekplugins.com/REALStudio/Lexing.html.
The plugin supports the Mac M1 chip (arm62) in addition to the x86-64 and i386 intel chips. Windows is supported for win32 and win64 configurations. Several internal fixes and add-ons relating to the latest version of scintilla have been incorporated in this current version.
If you need support, please do not hesitate to contact me, whether you try a demo version or a licensed version. Demo and the licensed plugin are exactly the same when you run it in the Xojo-IDE. In a built application the demo plugin throws a nagging window.
