import { setcmdline } from "https://deno.land/x/denops_std@v6.4.0/function/mod.ts";
Set the command line to {str} and set the cursor position to {pos}. If {pos} is omitted, the cursor is positioned after the text. Returns 0 when successful, 1 when not editing the command line.
Can also be used as a method:
GetText()->setcmdline()
