import { fn } from "https://deno.land/x/ddu_vim@v4.0.0/deps.ts";
const { insert } = fn;
When {object} is a List or a Blob insert {item} at the start
of it.
If {idx} is specified insert {item} before the item with index
{idx}. If {idx} is zero it goes before the first item, just
like omitting {idx}. A negative {idx} is also possible, see
list-index. -1 inserts just before the last item.
Returns the resulting List or Blob. Examples:
:let mylist = insert([2, 3, 5], 1)
:call insert(mylist, 4, -1)
:call insert(mylist, 6, len(mylist))
The last example can be done simpler with add().
Note that when {item} is a List it is inserted as a single
item. Use extend() to concatenate Lists.
Can also be used as a method:
mylist->insert(item)
