import { fn } from "https://deno.land/x/ddc_vim@v0.0.13/deps.ts";
const { foldlevel } = fn;
The result is a Number, which is the foldlevel of line {lnum} in the current buffer. For nested folds the deepest level is returned. If there is no fold at line {lnum}, zero is returned. It doesn't matter if the folds are open or closed. When used while updating folds (from 'foldexpr') -1 is returned for lines where folds are still to be updated and the foldlevel is unknown. As a special case the level of the previous line is usually available. Can also be used as a |method|: GetLnum()->foldlevel()
Parameters
