gistfile1.txt

# Docs say to add something like this to bash profile:
# $ eval "$(jenv init -)";

# This doesn't work with fish

# If you just manually run...
#
# $ jenv init - 
#
# ...then it shows you the content that would be eval'd

# If you just manually run...
#
# $ jenv init
#
# ...then it shows you the proper way to initialise it!
#
# # Load jenv automatically by adding
# # the following to ~/.config/fish/config.fish:

status --is-interactive; and source (jenv init -|psub)
