Is there a current syntax highlighting file for GRUB configuration files? If so, where may I find it?
I recently edited
sudoedit) and found that vim did no syntax highlighting for it. Filetype was set to CONF; when I changed it to GRUB, there was still no syntax highlighting.
A check on
/usr/local/share/vim/vim90/syntax/grub.vim shows it was last updated in 2006, whereas GRUB 2 was released in 2012, so I'm assuming the current syntax file is for GRUB Legacy.
EDIT 2022-07-31: In response to a good suggestion below, I was able to track down the person whom I believe to be the original maintainer. (One is never guaranteed to keep the same e-mail address for sixteen years.) I've contacted him and have yet to receive a response.
