> Highlighting and colouring of the command line is supported.

Does this mean something like syntax highlighting for the command line is now possible?

I'm using zsh-syntax-highlighting[1] for that, which requires 4.3+, so it will work here.

It's pretty great as a starting point, but it really could use more people writing highlighter plugins for different things. It's on my list of things to figure out how to do eventually.

It was already possible with https://github.com/zsh-users/zsh-syntax-highlighting.

Fish is another shell that supports syntax highlighting out of the box.
