Syntax highlighting is a feature of text editors that is used for programming, scripting, or markup languages, such as HTML. The feature displays text, especially source code, in different colours and fonts according to the category of terms.
It’s not only text editors that offer syntax highlighting. We explore specialised tools that offer syntax highlighting for a whole raft of programming languages.
