import { findfile } from "https://deno.land/x/denops_std@v6.4.0/function/mod.ts";
Just like finddir(), but find a file instead of a directory.
Uses 'suffixesadd'.
Example:
:echo findfile("tags.vim", ".;")
Searches from the directory of the current file upwards until it finds the file "tags.vim".
Can also be used as a method:
GetName()->findfile()
