Detect nyaovim with `has` command #113

Open techhazard opened 7 years ago

techhazard commented 7 years ago

I would like to be able to detect if nyaovim is running or not so I can load plugins conditionally. E.g. withhas('nyaovim') just like has('nvim') and has('python')

Expected Behavior

running nyaovim: :echo has('nyaovim') -> 1 running gui or terminal: :echo has('nyaovim') -> 0

Actual Behavior

running nyaovim: :echo has('nyaovim') -> 0 running gui or terminal: :echo has('nyaovim') -> 0

Steps to Reproduce (including precondition)

  1. Start nyaovim
  2. run the following command: :echo has('nyaovim')
  3. output should return 0 (I would have expected 1)

Screenshot on This Problem (if possible)

I do not think that is neccessary

Your Environment

has() is a built-in function. So we can't change it's behavior. Instead, we can check if g:nyaovim_version variable exists or not.

if exists('g:nyaovim_version')
  " Code for NyaoVim
endif

The variable is set in command line argument: https://github.com/rhysd/NyaoVim/blob/master/renderer/nyaovim-app.ts#L253

That would work. Sadly it doesn't for me. :echo exists('g:nyaovim_version') returns 0 :-( I do not have to use that command line argument manually, right?

rhysd commented 7 years ago

Hmm... I don't have any idea why the variable does not exist.

You don't need to set the command line argument manually. It is automatically set by NyaoVim.

Anything I can do to debug the issue?

Thank you for your information and offer. But I need to try to reproduce at first with the latest neovim.

Same issue here: on Linux it's exists, while on Windows it isn't.

Linux (Ubuntu 16.04 LTS "Xenial Xerus" x64)
