import { fn } from "https://deno.land/x/ddu_vim@v4.0.0/deps.ts";
const { swapname } = fn;
The result is the swap file path of the buffer {expr}.
For the use of {buf}, see bufname() above.
If buffer {buf} is the current buffer, the result is equal to
:swapname (unless there is no swap file).
If buffer {buf} has no swap file, returns an empty string.
Can also be used as a method:
GetBufname()->swapname()
Parameters
denops: Denops
buf: BufNameArg
