ZSH Prompt/RPrompt Conflict

I currently have my ZSH PROMPT variable set up as:

PROMPT=$'[%{\e[0;32m%}%n@%m:%~%{\e[0m%}]>

and my RPROMPT variable as:

RPROMPT=$'[%{\e[0;32m%}%T\e[0m%}]'

The effect I'm working for is to make the brackets and ">" white (using Terminal text-color settings) and everything inside of those gre开发者_开发问答en. However, when RPrompt is enabled in OS X (Ubuntu works fine), text entry begins 3 characters INTO the LPrompt, and overwrites the last 3 characters!!

What is the proper way to color my ZSH Prompt and RPrompt to avoid this issue?

Your RPROMPT messes up for me on Ubuntu. Since zsh knows ANSI color sequences and has its own facility for that (which automatically takes care of zero-width correction, too), try this:

RPROMPT='[%F{green}%T%f]'

And, by the way:

PROMPT='[%F{green}%n@%m:%~%f]>'
