I've created this user-defined language that you'll find here.

Either copy the code inside and add it to your userDefineLang.xml (%appdata%/notepad++).

Or in notepad++, click on Language > Define your language > Import.

It should be already linked to "inp" extension (you shouldn't put ".inp" in the "ext" box).
