Vim 8 support

[braun-steven]

Hey David, thanks for working on this plugin!

After logging into overleaf and opening a project and running :call Airlatex(), the sidebar pops up and :messages is populated with the following error:

Error detected while processing function AirLatex_project_update:
line    2:
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/tak/.vim/plugged/AirLatex.vim/python/sidebar.py", line 459, in <module> sidebar.triggerRefresh()
  File "/home/tak/.vim/plugged/AirLatex.vim/python/sidebar.py", line 46, in triggerRefresh vim.async_call(refresh)
AttributeError: module 'vim' has no attribute 'async_call'

This error continues to pop up when I want to navigate in the AirLatex sidebar. No connection can be established.

Here is the output of vim --version if it helps you:

Let me know if I can provide more information.

Additional information:

• Firefox Version: 70.0.1
• OS: Arch Linux (Kernel 5.3.7, Zen)
• Minimal .vimrc:

  call plug#begin('~/.vim/plugged')
  Plug 'da-h/AirLatex.vim'
  call plug#end()
  let g:airlatex_domain="www.overleaf.com"

Edit: Adjusted the airlatex_domain to Overleaf and it now works in NeoVim.

Hi Steven!

Looks like the default domain is indeed a little bit outdated, I issued a PR (#3) to solve that.

Hey @steven-lang,

thanks for this issue & your suggestions!

Unfortunately, vim.async_call is indeed neovim only. However, I am currently working on a synchronized GUI handler that should also work with vim. (I will merge that branch in the next 3-5 days).

Best da-h

PS: I just found a bug related to pushing changes to the server. Now, the plugin is not yet useable in the direction vim -> overleaf-server.

[braun-steven]

Ah good to know. Since 8.0, Vim supports async jobs as well, but the API for that seems to be more complicated, see channels.

[da-h]

Thanks for the reference!

BTW: as of 8a6d06f everything should work right now. ;)
