The only stock script which does anything like that is help.fish and what
it does isn't really what you're looking for. Using the new "string"
builtin:
set -l fish_version (echo $FISH_VERSION | string split '.')
Then $fish_version[1] is the major number, $fish_version[2] the minor, etc.
If you need the solution to work on fish versions older than 2.3.0 (which
don't have the string builtin) you'll need to do it the hard way:
set -l fish_version
for i in 1 2 3
set fish_version[$i] (echo 2.3.1 | cut -d . -f $i)
end
