Displays tildes in the fringe on empty lines a la Vi.
Original idea from /r/emacs.
The package will be available soon in MELPA.
If you have MELPA in package-archives, use
M-x package-install RET vi-tilde-fringe-mode RET
If you don't, open vi-tilde-fringe.el in Emacs and call
package-install-from-buffer.
To toggle the mode locally:
M-x vi-tilde-fringe-mode
To toggle the mode globally:
M-x global-vi-tilde-fringe-mode
To turn it on automatically only for programming modes:
(add-hook 'prog-mode-hook 'vi-tilde-fringe-mode)
Open the customization group buffer:
M-x customize-group RET vi-tilde-fringe RET
There you can change the bitmap array or the face of the symbol drawn in the
fringe. By default the symbol is a tilde :-) and its face simply inherits from
default.
