import { prompt_setinterrupt } from "https://deno.land/x/denops_std@v3.6.0/function/mod.ts";
Set a callback for buffer {buf} to {expr}. When {expr} is an empty string the callback is removed. This has only effect if {buf} has 'buftype' set to "prompt". This callback will be invoked when pressing CTRL-C in Insert mode. Without setting a callback Vim will exit Insert mode, as in any buffer. Can also be used as a |method|: GetBuffer()->prompt_setinterrupt(callback)
