Using vim // gvim with unix file format under Windows 10 + Cygwin gets errors from both

Question

This is the second of two errors posted tonight. As mentioned before, I did re-install vim/gvim 8.2 to make sure I'd installed it as administrator, as instructed, to make sure the batch files, etc., got installed.

I move files around between Linux and Windows constantly, and use the unix file format for everything to avoid constantly having to do :%s/^M//g every time I move a file around. I had this silenced (by some magic, it just finally shut up). I have set fileformat=unix in my .vimrc as the first non-comment line. But when opening the first file, it will always give me the following errors (having to add blank lines to keep them from becoming one giant mess of a paragraph - Each error is followed by line 1):

Error detected while processing C:\jim\bin\Vim\vim82\plugin\getscriptPlugin.vim:

Each of the above is followed by: W15: Warning: Wrong line separator, ^M may be missing

If I exit out of vim//gvim, I get the same errors again. If I use :e foo.bar to simply edit the file again, or another file, or split, etc., I don't get the same errors. I looked at the various .vim files, saved them in unix format, and thought that might stop these error messages. No such luck.

Answer 1

All you need to do is:

set fileformats=unix,dos

In your vimrc, and not manually set 'fileformat'. This makes unix the default 'fileformat' for new files, while allowing Vim to properly handle DOS file formats.

Answer 2

It's not a perfect solution, but I did silence those warnings. Seems all of the files that gvim (again, not vim) was griping about were in the vim 8.2 distribution, all .vim files. I just set those to dos format. So I gather those files are loaded prior to loading my ~/.vimrc, where the first two non-commented lines are:

set ffs= set ff=unix

I also copied what was left in my old ~/.exrc file (from many decades ago, before vim existed and I used normal vi) and renamed it to get it out of the way (for some reason, I can't convince myself to rm old config files; oh wait, I know why, it always eventually comes back to bite me when I do). It was also one of the files gvim was complaining about.

So I'm happy. Thanks, everyone, for pointing me in the right directions to find the above solution (or do we call it a band-aid?). It works. Good enough.
