I have this string in init.vim:
set background=white " FR!
I want to bind this command to a keymap in init.vim (for find and replace text, that's why I use " FR!, to make sure it will not replace another line):
:!sed -i 's/set background=white " FR!/set background=dark " FR!/g' $MYVIMRC
Of course, the command isn't working, bcause the syntax is wrong. Vim is confusing " as a comment. So what is the correct syntax to execute that command ?
Example use of 'sed':
sed -i 's/old-text/new-text/g' input.txt
_sed is a default tool of linux for find and replace a string in a file, without opening it.
_!sed is tell nvim to execute it as a command, by add '!' before sed.
_$MYVIMRC is a path to init.vim.
_Execute it in : command line is ok, the problem is binding it to a keymap in init.vim.
Summary: Execute the command in nvim, change a setting in init.vim without open init.vim file. So next time I open nvim, it will remember my last change.
