Conky/Dzen2 and variables from shell

I'm trying to make some dzen2 stuff, but i have some hard time on one point. I want to eval color variable between conky and dzen2.

Something like that:

Colors :

#!/bin/zsh

#################################
## Colors for Dzen2 status bar ##
#################################

##
## TEST Colors
##
COLOR_TEST='#000000'

Conkyrc :

#################################
## Conky for Dzen2 Status Bar  ##
#################################

background no
out_to_console yes
out_to_x no
override_utf8_locale yes
update_interval 1
total_run_times 0

TEXT
##
##  TEST
##
  ^fg($$COLOR_TEST)

Script:

#!/bin/zsh

. ./colors
conky -c conkyrc | dzen2 -p

I tried eval/echo on conky, but nothing sucessfull. If somebody have an idea, it will be really nice.

Thanks anyway

Have a good day

EDIT:

If we can't find a solution about the main question, what's the best idea?

  • Lua/Conky (I think it's not bad)
  • Shell/Dzen2 (Performance are not amazing last time i tried that)
  • A full program in C++ (A little overkill, and conky is generic)
Solution

  • How about to use ${execp my-dzen-help.sh getcolors }, in conky ? 

    #my-dzen-help.sh

getcolors(){
printf '^fg($$COLOR_TEST)'; # or what ....
}
