Standard module for denops.vim.

This module is assumed to be used for developing denops plugins. The code is assumed to be called in a dedicated worker thread.

By using this module, developers can write Vim/Neovim denops plugins like:

import type { Denops } from "";
import * as batch from "";
import * as fn from "";
import * as vars from "";
import * as helper from "";

import { assert, is } from "";

export function main(denops: Denops): void {
  denops.dispatcher = {
    async init() {
      // This is just an example. Developers usually should define commands directly in Vim script.
      await batch.batch(denops, async (denops) => {
        await denops.cmd(
          `command! HelloWorld call denops#notify("${}", "say", ["World"])`,
        await denops.cmd(
          `command! HelloDenops call denops#notify("${}", "say", ["Denops"])`,
    async say(where) {
      assert(where, is.String);
      const [name, progname] = await batch.collect(denops, (denops) => [
        fn.input(denops, "Your name: "),
        vars.v.get(denops, "progname"),
      const messages = [
        `Hello ${where}.`,
        `Your name is ${name}.`,
        `This is ${progname}.`,
      await helper.echo(denops, messages.join("\n"));

Note that developers should avoid calling initialization code within the main function. If necessary, add an init API or a similar approach like above and call it from plugin/<your_plugin>.vim.

See Denops Documentation or denops-helloworld.vim for more details.
