E349: No identifier Under Cursor

[kaiyulee]

I don't know how to describe this issue, please see the jpg

fixed: let g:TerminusFocusReporting=0

[wincent]

Unfortunately I don't really get what I am seeing in the jpg. It is very blurry on my machine. Is it supposed to be an animated gif?

Also, see :h E349 for more context on what the error supposedly means (doesn't seem to have a lot to do with focus reporting; I wonder if you have any bindings involving *).

I also started seeing this error after updating terminus today. It happens when I first start Vim. A git bisect points me at 9382e00a95f876a85 as the culprit and can verify that adding let g:TerminusFocusReporting=0 makes the error no longer appear.

[wincent]

I suspect some interaction with a plug-in, so will need a bit more help to repro this.

[lencioni]

I removed all plugins except for the following:

terminus     vim-pathogen

and the problem persists.

Perhaps there is something up with the version of vim I am on, or possibly something in my configuration. I can dig in some more later, but unlikely today.

Actually, I tracked it down to this line in my vim config:

nnoremap <silent> <Esc> :nohlsearch<CR><Esc>

[lencioni]

Interestingly, this also triggers it:

nnoremap <silent> <Esc> <Esc>

[lencioni]

Also, FYI I've updated Vim to include patches through 666 and same issue.

[wincent]

Thanks for the minimal repro, @lencioni. I can repro it, although I haven't thought of a fix for it yet. Doesn't repro in Neovim, BTW.

[wincent]

Workaround: define any multi-char mapping starting with <Esc>, even a nonsense one:

nnoremap <Esc><Esc> <nop>

You'll get the annoying delay mentioned in 9382e00a95f876a8512f11ea296be727be4c26d0, but at least you won't see that error.

[rcarraretto]

fwiw, I was having an issue with the file reloading feature and, thanks to this thread, I fixed it by removing a very similar line from my vimrc (it was an unused mapping anyway):

nnoremap <silent> <esc> :noh<cr>

for the record, my issue was:

• I would open vim in a dir (netrw) and I would see E349.
• when vim gained focus I would see some message basically showing me the file path and that required me to press enter. the file wouldn't reload as expected.

iterm2, tmux 2.4, vim 8

thanks, folks!

[lencioni]

I believe this same mapping recently starting causing more annoying problems with terminus that sound very similar to what @rcarraretto was experiencing. Main difference is that my prompt showed me a few lines in the file around where my cursor was.
