A library for building Neovim plugins in OCaml.

Reviewing

Most of this library is a direct port of the neovim remote API.
For review, consult the following help pages:

• :help api.txt

• :help msgpack-rpc

• :help --embed

• :help --headless

• :help --listen

Structure

Almost all of the functions in the library are small idiomatic shims on
top of the auto-generated functions produced by lib/neovim_api_wrapper
Those that have not been tested are in Untested submodules.

VCaml

• Library entrypoint

• API type definitions

  • OCaml -> Neovim: Defun.Vim.t

  • Neovim -> OCaml: Defun.Ocaml.t

  • These types can't be unified for deep GADT reasons.

Api_call

• A type that represents an API call that can be executed

• A let-syntax for combining these types

Nvim

• Functions that operate on global Neovim state

Buffer

• Functions that operate on Neovim buffers

Window

• Functions that operate on Neovim windows

Tabpage

• Functions that operate on Neovim tabpages

Ui

• Functions that operate on the Neovim UI

Client

• Client.t is opaque to library users. You can interact with clients
  via the interface exposed in [Vcaml], but for the most part it is an
  opaque object that is just passed to functions that need it.

Client_info

• Client_info.t is some data that is present for every plugin,
  embedder, or UI that is attached to Neovim.

Keymap

• A type for representing key mappings

Command

• A type for representing commands (e.g. ":Foo")

Color

• Types for representing colors and highlights

Mark

• A type for representing a mark (e.g. "'m")

Mode

• A type for representing a mode (e.g. "Normal")

Transport

• Generic code for setting up communication between OCaml
  and Neovim

Extract

• Utilities for pulling values out of VCaml related msgpack objects.

Notifier

• Functions that let you send Neovim asynchronous notifications.
  In most cases this isn't something you want to do: normally you only
  want to (1) send synchronous requests & responses back and forth, and
  (2) receive asynchronous notifications.
