vim reports "Invalid expression" in syntax/sls.vim

[cboltz]

I'm using vim-8.2.2607.

When editing a sls file, vim complains about the following "Invalid expression" on startup:

# vi whatever.sls
Error detected while processing /etc/vimrc[42]../usr/share/vim/vim82/syntax/syntax.vim[42]..BufRead Autocommands for "*.sls"..function DetectSls[5]..FileType Autocommands for "*"..Syntax Autocommands for "*"..function <SNR>3_SynSet[25]..script /home/cb/.vim/syntax/sls.vim:
line   67:

line   68:
E10: \ should be followed by /, ? or &
line   69:
E10: \ should be followed by /, ? or &
Press ENTER or type command to continue

Can you please fix this?

Unable to reproduce on my machines (macOS 10.15 w/ vim 8.2.2650 or Ubuntu 20.10 w/ vim 8.2.0716). Can you expand on how you have have Vim installed? Maybe share your relevant parts of your vimrc?

I've seen similar issues when only a vim-minimal package is installed.

I use vim 8.2.2607 on openSUSE Tumbleweed. I also have the vim-data package installed, so it's not a minimal vim install.

IIRC I first noticed the problem a month or two ago, so it might be introduced by a vim update or by an update of a distro-packaged vim file.

I installed salt-vim in 2017, and IIRC didn't update it since then.

Regarding vimrc - I load sls.vim via symlinks in the ftdetect, ftplugin and syntax directories in ~/.vim:

cb@tux:~/.vim> find -type l -ls |grep sls
... lrwxrwxrwx   1 ... Nov 13  2017 ./ftdetect/sls.vim -> ../__DOWNLOAD/salt-vim/ftdetect/sls.vim
... lrwxrwxrwx   1 ... Nov 13  2017 ./ftplugin/sls.vim -> ../__DOWNLOAD/salt-vim/ftplugin/sls.vim
... lrwxrwxrwx   1 ... Nov 13  2017 ./syntax/sls.vim -> ../__DOWNLOAD/salt-vim/syntax/sls.vim

and additionally have in my .vimrc (not sure if it's needed or if it predates installing salt-vim)

autocmd BufNewFile,BufRead /*.sls set expandtab

Your autocmd line looks problematic. Comment it out or try:

autocmd FileType sls setlocal expandtab

Tried that, and even moved away ~/.vimrc. Unfortunately I still get the same error message.
