updated color sequences as variables

updated color sequences as variables

[Russell Hoover]

I've been using a group of colors-put-into variables that someone put on
this list a while back, which (in the old color-coding scheme) looked like
this:

red="%{$(echo -n '\e[1;31m')%}"
green="%{$(echo -n '\e[1;32m')%}"     etc.,


and could be used (i.e., in a prompt) like this:

export prompt="$yellow($blue%n$yellow<$cyan@$yellow>$red%m$yellow($green%/$yellow)$red-$yellow> $white"

Would the coding in the variables translate -- updating to the new color scheme of
sequences -- to anything like the following?

red="%{$(\e[1;31m)%}"

if not, what would make sense here, and how would it be put into a prompt
string?  I'd like to continue using a system like this, it makes creating
a prompt much easier.

Take a look at the "colors" function that is included with the zsh 4.0.x
distributions.  Look for "colors" in the index of the texinfo zsh manual,
or read "man zshcontrib".

You'd want

  red=$'%{\e[1;31m%}'

Or

  autoload colors
  colors
  red="%{${fg[red]}%}"
