My own attempt at syntax highlighting for Notepad++.
Up to date as of 2019 with all the DLC content and the new features from UserPatch 1.5
It will highlight constants from UserPatch 1.5 that need to be defined first (with #const) before they are actually usable. Most of these are defined by default in WololoKingdoms. If you want your map to work on vanilla UP 1.5 you need to explicitly define them though, so it's probably best to always do that.
Install in Notepad++ by going to language -> define your language -> import
