Add custom markup to txt files in Notepad++

Question

I want to add some keywords that are highlighted (for example [FAIL] in red and [PASS] in green) into Notepad++. How would I do that for a .txt file?

Answer 1

You have to create a User Defined Language or modify one of the existing ones.

There is a UI inside of Notepad++ for defining the keywords and markup (it's a bit involved). You can access it from Language -> Define your language...
