popup function where your cursor is in
Which Func Mode will display the current function name in the mode line.
But I can't use it.
It's because I reduce my mode-line into minimum to make it work with my tiny netbook.
Showing the function in header is also not possible because it conflicts with my color theme.
So I choose to display the function name in a popup.
Insert below code into ~/.emacs,
(autoload 'which-function "which-func") (autoload 'popup-tip "popup") (defun copy-yank-str (msg) (kill-new msg) (with-temp-buffer (insert msg) (shell-command-on-region (point-min) (point-max) (cond ((eq system-type 'cygwin) "putclip") ((eq system-type 'darwin) "pbcopy") (t "xsel -ib") )))) (defun popup-which-function () (interactive) (let ((msg (which-function))) (popup-tip msg) (copy-yank-str msg) ))
The extra bonus is "popup-which-function" will also insert the function name into clipboard and kill ring.
The above code need package "popup.el" to be installed.
