How to test for :terminal support?

Question

I have neovim 0.3.4 installed which means I can run the :terminal command, however, doing :echo has('terminal') shows 0.

So, I wonder if there is any other way I can test for its support because all my terminal mappings wrapped within an if has('terminal)...endif do not work.

According to the vim manual that is the way to test it

The terminal feature is optional, use this to check if your Vim has it: echo has('terminal') If the result is "1" you have it. -- https://vimhelp.org/terminal.txt.html

Thanks

Answer 1

You can use

if exists(':terminal')

to check for existence of the terminal command. This works in both vim and neovim.

Answer 2

As said by Christian Brabandt in the question's comment:

neovim always has the terminal included, so you can simply use has('nvim') the other test is for Vim specifically.
