I\'m trying to add the syntax plugin for the Go programming language in Notepad++.
There is a repository for such user-defined languages. I downloaded and unzip
If you don't have any user languages defined before, then after renaming userDefinedLang_Go.xml to userDefinedLang.xml, also edit the text of file by adding the tags around the original content.
userDefinedLang_Go.xml
userDefinedLang.xml
