From which language is the ImageJ Macro Language derived?

I was wondering what the parent language of the ImageJ Macro Language was. Let’s say, for instance, I want to edit my ImageJ macros in another editor with syntax highlighting. What is the language closest to the ImageJ Macro Language that I would tell that other editor my current scripting language is?

If you use notepad++ Java usually works fine.
Otherwise you can try the custom IJmacro syntax highlighting for notepad++ by @Kota :wink:


When pasting ImageJ macro snippets here on the forum inside of code fences (```), I use javascript for the language hint.
