Thanks ill try to replicate today

[ryanoasis]

So far I am unable to replicate so far though I have not tried the exact setup you have.

Do you have a link to your vimrc you are using so I can test if there is anything specific in it?

[dflupu]

I would have a hard time sharing my vimrc, since it's split into multiple files.
I went ahead and tested with a vimrc containing only the following

call plug#begin()
Plug 'scrooloose/nerdtree'
Plug 'ryanoasis/vim-devicons'
call plug#end()

and the issue did not go away. Autoload directory only contains vim-plug. Also tested with pathogen.

[ryanoasis]

@dflupu Ah okay thanks, I'll try again

[ryanoasis]

can you tell me what you get for the output of echo g:NERDTreeUpdateOnCursorHold ?

[dflupu]

E121: Undefined variable: g:NERDTreeUpdateOnCursorHold
E15: Invalid expression: g:NERDTreeUpdateOnCursorHold

[ryanoasis]

Hey thanks for testing that. Looks like you found a bug (oversight on my part).

See I use nerdtree-git-plugin and I stole/borrowed a fix idea from there for refreshing the nerdtree flags but looks like I forgot to even set that variable!

See my commit on the initial attempt at a fix: 710f3b2

But I need to do something (as shown here: https://github.com/Xuyuanp/nerdtree-git-plugin/blob/e71e62fb5ca3e49035a7f2a85c81e5b85b1cf138/nerdtree_plugin/git_status.vim#L37-L39) for setting that variable 😊

So basically I could not replicate your issue until I removed the nerdtree-git-plugin plugin and now I get the same error as you.

[ryanoasis]

The fix is up on 0.8.3 branch if you would like to test it out.

I won't be able to do any changes until Tuesday

[dflupu]

I've tested it a bit. It does work, but it takes some time until the icon appears after a file is created. Seconds, even. Is it based on some kind of timeout ?

[ryanoasis]

@dflupu Yeah basically it is as far as I understand. I will see if I can try to improve the speed a bit.

Try to see what you have set for updatetime

For me I have it set to 250 for gitgutter in my vimrc so that is why I probably see the icon show up fairly quickly, without it the default seems to be 2 seconds (2000).

[dflupu]

That pretty much solved it. Thanks !
The default updatetime in my version of vim was actually 4 seconds.

[ryanoasis]

Great! No problem 😄

I will try to add this info to the readme for the next release
