Emacs: Show Buffer File Name
I share my Emacs configuration on GitHub, but the truth is
that most of the fun stuff happens in my
(mentioned previously), which I don’t share.
It’s growing rather large and some of the contents are fairly mature
so I’m going to going to work on moving more things into my stable
config and I may as well share them along the way.
One little utility I’ve grown quite fond of is my
(defun camdez/show-buffer-file-name () "Show the full path to the current file in the minibuffer." (interactive) (let ((file-name (buffer-file-name))) (if file-name (progn (message file-name) (kill-new file-name)) (error "Buffer not visiting a file"))))
…which I keep on C-x C-p, overriding the fairly useless
(global-set-key (kbd "C-x C-p") 'camdez/show-buffer-file-name)
It’s fairly self-explanatory but notice that it not only shows you the
path to the current file but also leaves it on the
find this to be pretty useful when switching to the shell to operate
on a file (though obviously there are lots of ways to do such things
within Emacs), and for pasting filenames into GitHub discussions,
emails, or the company chat room.
