   I don't have any special interest in fish. Do you want to work on contributing support, @DimanNe ?

   I don't see Fish ever working, TBH. I wrote this little test script in #105 to explore the best way of setting $VIRTUALENVWRAPPER_SCRIPT:

   # Saved as test_arg0.sh
   echo "0: $0"
   echo "BASH_SOURCE: ${BASH_SOURCE}"
   echo "ZSH_ARGZERO: ${ZSH_ARGZERO}"
   echo "ZSH_SCRIPT: ${ZSH_SCRIPT}"

   Then I tried to run it through Fish:

   $ fish
   ferd@$HOSTNAME /tmp> source test_arg0.sh
   test_arg0.sh (line 2): Variables cannot be bracketed. In fish, please use "$BASH_SOURCE".
   echo "BASH_SOURCE: ${BASH_SOURCE}"

   If Fish rejects ${VARIABLE} syntax, that's game over. It'd require a complete rewrite that'd no longer be compatible with any of the other shells.

   It seems the equivalent Fish syntax is {$VARIABLE}. My eyes cannot roll any harder.

   I'd be inclined to close this pending an interested party providing a proof-of-concept.

   +1 from me, unless some Fish user wants to port the setup script to their shell and include it as an additional implementation I think Fish support is dead in the water. It's insufficiently Bourne-compatible to be able to use the same shell scripts as the currently-supported shells.
