I really don't care about any of the "value" that viminfo or its replacement in neovim, ShaDa, provide. I couldn't care less about whether or not my cursor is in the exact place I left it when I open a file or whether my registers are restored, but I am very tired of seeing seemingly random ShaDa-related errors. Is there a way that I can just turn off shared data? :help shada has not been very helpful in this endeavor.
set shada="NONE" will prevent shada files from being generated or read in Neovim.
For vim, set viminfo="NONE" will disable viminfo files.
According to the neovim docs, if you invoke neovim with -i NONE, it will ignore the ShaDa file.
Insert the following into your bashrc:
alias nvim='nvim -i NONE'
