Vim shows the following long error message when I
open a file that has a dot-ini (.ini) file extension:

Error detected while processing
/usr/share/vim/vimrc[25]../usr/share/vim/vim90/syntax/syntax.vim[44]..BufRead
Autocommands for "*~"..BufRead Autocommands for "*.ini"..FileType
Autocommands for "*"..Syntax Autocommands for "*"..function
<SNR>3_SynSet[25]..script /usr/share/vim/vim90/syntax/dosini.vim: line 28:
E10: \ should be followed by /, ? or &

Implementing that suggestion at the end of the message had no effect. (Or,
rather, it made the error message even longer and more incrutable.)

I have vim-plug, the vim plugin manager, in ~/.vim/autoload/plug.vim but no
plugins currently installed,

How can I get Vim to open .ini files without showing error message(s)?

Thank you for reading.

Try temporarily to remove (back it up somewhere)

/usr/share/vim/vim90/syntax/dosini.vim

If the message persists, may be the error comes from
~/.vim/autoload/plug.vim thus removing (backupping) it too might help.

Depending on the results, investigate these files before writing them back.

Strange. Neither of syntax/dosini.vim files in vim-runtime debian packages - buster, bullseye, bookworm, trixie, sid - contain '\' character in the line 28. This appear in the recent git versions of that file but should not reach debian packages yet ? (Yet may be I do not understand as well update mechanisms of debian. Anyway, with recent git version of that file I cannot reproduce reported problem - opensuse user here). If you can share the content of that file: /usr/share/vim/vim90/syntax/dosini.vim, may be that will lead to something... Another advice - post the question in vim_use google group, that would expose your question to much wider selection of experts probably.

With best regards, Anton

This problem has been solved by replacing the
/usr/share/vim/vim90/syntax/dosini.vim
file dated *2023 Jun 27* with the one dated *2023 Aug 20*

Thanks, Christian.
