How to access remaining arguments in a fish script

Question

my-fish-script a b c d

Say you want to get the all arguments from the second argument onwards, so b c d.

In bash you can use

Answer 1

The behaviour of the shift command can be simulated with set -e/--erase VARIABLE_NAME.

The idea is to erase the first argument, then get the remaining arguments from the $argv list.

For example

function loop  --description "loop  "
  set count $argv[1]
  set --erase argv[1]
  for i in (seq 1 $count)
    eval $argv
  end
end

Usage

$ loop 3 echo hello world
hello world
hello world
hello world
