I'd like to add a function to my config.fish to do some things over and over
. . . basically, to set my path:
function add_to_path --description 'If the directories exist, add them to
the path'
for arg in $argv
if [ -d "$arg" ]
# Eventually do this uniquely . . .and, allow the function to
specify head or tail of the path.
set -x PATH $PATH "$arg"
else
echo "WARNING: Directory [$arg] does not exist -- not adding to
PATH"
end
end
end
Then, later on in the config.fish, actually use it:
add_to_path ~/.gem/ruby/1.8/bin
add_to_path ~/bin
etc . .
But, I don't want this function to exist after config.fish is done. Should
I just erase it before the end of my config.fish:
functions -e add_to_path
Or is there an easier way to make a function that is non-global in scope?
I think this will be my last stupid question of the AM . . . .:)
