Does not overwrite when run from NeoVim (:YcmGenerateConfig)

[waldnercharles]

:YcmGenerateConfig will prompt to overwrite, but will return 1 immediately when in NeoVim.

Is this expected behavior?

No, interactive behaviour is expected when run from Vim. Looks like this is due to a difference in how Neovim spawns processes - run :! cat terminates immediately as well. As explained in neovim/neovim#1477, this is because child processes do not get access to tty (since that would break the msgpack-rpc UI).

It's possible to workaround this using :terminal and the new job control API (I actually implemented this as an experiment), but on reflection it makes more sense to simply change the command to not overwrite unless it's suffixed with ! (for consistency with :w!, etc.)

I've pushed a fix for this to develop - can you verify it's working?

[Yanhao]

I got the same issue in with vim(not neovim)

[rdnetto]

@YanhaoMo Please open a separate bug for that - Vim and Neovim handle child processes differently.
