import { fn } from "https://deno.land/x/ddc_vim@v4.1.0/deps.ts";
const { prevnonblank } = fn;
Return the line number of the first line at or above {lnum} that is not blank. Example:
let ind = indent(prevnonblank(v:lnum - 1))
When {lnum} is invalid or there is no non-blank line at or
above it, zero is returned.
{lnum} is used like with getline().
Also see nextnonblank().
Can also be used as a method:
GetLnum()->prevnonblank()
