Dear Haskell-Cafe, I am wondering if there is a way to use variables in paths that appear in .cabal/config file? I have written a custom config file that I would like to share. However, my config file contains full paths s.a. world-file: /home/semen/.cabal/world etc. Is there any way I could make it less personal, e.g. world-file: /home/${HOME}/.cabal/world Many thanks, Sem -- Семен Тригубенко
