How can I change the default terminal in Neovim (lua)?

Question

I have tried adding this line to the init.lua but it doesn't work and I don't understand the syntax:

local g:terminal_emulator="powershell"

I get an error upon running the source command: it says unexpected symbol near :

Answer 1

In Lua the syntax is slightly different.

I would do:

vim.g.terminal_emulator='powershell'

Or:

vim.api.nvim_set_var('terminal_emulator', 'powershell')

Answer 2

If you want to configure the :terminal command you have to change the 'shell' setting instead.

In Lua you can do with

vim.opt.shell = 'powershell.exe'
