import { deletebufline } from "https://deno.land/x/denops_std@v4.1.4/function/mod.ts";
Delete lines {first} to {last} (inclusive) from buffer {buf}. If {last} is omitted then delete line {first} only. On success 0 is returned, on failure 1 is returned. This function works only for loaded buffers. First call |bufload()| if needed. For the use of {buf}, see |bufname()| above. {first} and {last} are used like with |getline()|. Note that when using |line()| this refers to the current buffer. Use "$" to refer to the last line in buffer {buf}. Can also be used as a |method|: GetBuffer()->deletebufline(1)
