## neovim REPL for lua and vim script

**Works best with neovim 0.8**

Start a new instance with `:Repl`.

In insert mode type `/h` and enter to see available commands.

![demo](https://user-images.githubusercontent.com/59243201/200236872-97304492-6b4c-4de5-9cad-f530ce5eab3d.gif)

**NOTE:** If you're using an auto-completion plugin like `nvim-cmp`, read

[`:h neorepl-using-with-other-plugins`](doc/neorepl.txt#L101)!

Starts in lua mode by default. You can switch modes with `/vim` (short version:

`/v`) for vim script and `/lua` (short version: `/l`) for lua. You can also run

one-off commands with them, like for example `/v ls` to list buffers.

Multiple lines can get evaluated when line continuations start with `\` as the

very first character in the line. If you need to evaluate a line that starts

with `/` or `\`, add a space before. Note that vim script has line escaping that

works just like this. So to break lines in a single expression with vim script,

there has to be two backslashes. You can break line in insert mode with `CTRL-J`.

Lua has its own environment, variables from the REPL won't leak to the global

environment. Global environment is referenced in the `_G` variable. In vim script

you can use the `s:` scope, but it's shared between all REPL instances for now.

You can switch buffer and window context with `/b` and `/w` commands, so things

like `vim.api.nvim_set_current_line()` or `:s/foo/bar/g` will run on the other

buffer.

A new REPL instance can be also spawned with `require'neorepl'.new{}`. Example

function that mimics vim's cmdwin or exmode:

```lua

vim.keymap.set('n', 'g:', function()

  -- get current buffer and window

  local buf = vim.api.nvim_get_current_buf()

  local win = vim.api.nvim_get_current_win()

  -- create a new split for the repl

  vim.cmd('split')

  -- spawn repl and set the context to our buffer

  require('neorepl').new{

    lang = 'vim',

    buffer = buf,

    window = win,

  }

  -- resize repl window and make it fixed height

  vim.cmd('resize 10 | setl winfixheight')

end)

```

For the list of available options see [`:h neorepl-config`](doc/neorepl.txt#L120).
