Getting error when opening file

[farzadmf]

Hi, I'm using neovim, and when opening a specific file, I'm getting this error:

Error detected while processing function css_color#init[10]..css_color#enable:
line    3:
E12: Command not allowed from exrc/vimrc in current dir or tag search: ^Iaugroup CSSColor
line    4:
E12: Command not allowed from exrc/vimrc in current dir or tag search: ^I^Iautocmd! * <buffer>
line    6:
E12: Command not allowed from exrc/vimrc in current dir or tag search: ^I^I^Iautocmd CursorMoved,CursorMovedI <buffer> call s:parse_screen()
line   12:

line   13:
E12: Command not allowed from exrc/vimrc in current dir or tag search: ^Iaugroup END

To be more specific, I'm using byobu, and I'm doing nvim $( which byobu ) to open the file. The target file is /usr/bin/byobu, which is a "read-only" file.

I tried copying the file to a directory owned by me, but the error still happens. It seems that the issue is only with that specific file (which is a shell script), but I can't replicate it with any other file (even a shell script).

Any ideas what could be the issue here?

Thank you

What does :set secure? modeline? say

[ap]

(Mainly I’m trying to see whether this is neovim #9881. Personally I haven’t had luck reproducing the issue based on the description of that bug (and the underlying Vim 8.1 bug – caused by vim/vim@82e8c92 and then fixed in vim/vim@916a818).

Either way, it seems that secure is getting set somehow.)

Thank you @ap for your reply, the output of :set secure? modeline? is this:

nosecure
  modeline

And I'm sorry about the bug description; I know it's super specific, but that's the only situation I saw the message

[ap]

Huh! That is after you get that error message? Because it acts as if secure had been set… but that output says it wasn’t actually set?

[farzadmf]

Apparently, that's the case 😮 😕

I have the exact same error. Was able to reproduce it with a simple file (test.cfg) containing the line

# vi:syntax=cfg

My secure and modeline variables are the same as @farzadmf's.

@twidxuga pointed out a good thing; I checked the file I'm opening and it has this at the end:

# vi: syntax=sh ts=4 noexpandtab

[ap]

Was able to reproduce it with a simple file containing the line

Thank you for that! I can reproduce it that way too.

Same with # vi: syntax=sh

I also have this issue and the same nosecure modeline output to that query.

The solution is to change syntax to filetype, e.g. # vi: filetype=sh
