Great and thank you !

Thanks a lot!

How should I use this file?

How should I use this file?

I know I'm late to the party, but simply paste this code in a file scala.udl.xml in the folder for user defined languages (on Windows, under %appdata%\Notepad++\userDefineLangs), and restart Notepad++.

How should I use this file?

For Windows follow below steps:

1. Navigate to below path:
   C:\Users\<userID>\AppData\Roaming\Notepad++\userDefineLangs
2. Create empty file with name: scala.udl.xml
3. Open newly created-scala.udl.xml file and paste the whole code and save it
4. Restart Notepad++
5. Now Scala will get added below User Defined Language in Language menu item

thank you so much :)
