OpenBVE syntax highlighter for Notepad++ 7.9.1

I've downloaded a fresh copy of Notepad++ v7.9.1, the latest release. I found that the OpenBVE syntax highlighter plugin (from this thread) doesn't seem to work with it. I've tried both the 32 bit and the 64 bit versions of Notepad++. I guess there's incompatibility. Is there an easy fix to make the plugin work with the new Notepad++?

Hmm...

No idea where I put the source for that one

However, try the attached instead

Notepad++ now has native support for defining user languages.
Language ==> User Defined Language ==> Define Your Language


Import the zipped XML file from that dialog and you should be good.
Dead simple to add additional commands or change the colors, you should be able to see from there.
