bash color settings messing something up

blue="\033[38;5;32m\]\033[48;5;256m\]"
purple="\033[38;5;198m\]"
green="\[\033[0;32m\]"
reset="\[\033[0m\]"

export PS1="$purple\u$green\$(__git_ps1)$blue \W $ $reset"

If the colors were set using the simpler format, as for green, everything would work fine. But if they're set using the more complex format like in blue and purple, it would work and look right at first, but if I navigate through some previous commands etc. suddenly the line would jump into a really weird place and the prompt text would be gone.

What's going on here?

Solution

  • Make sure you surround the escape codes with \[ and \]. Those markers tell bash that these are non-printing characters.

    blue="\[\033[38;5;32m\033[48;5;256m\]"
purple="\[\033[38;5;198m\]"
