Hi,
I'm trying which-funciton-mode in ess-mode, and the imenu provide redundant information in case of which fun. For example, I juse tneed Functions, but imenu provide library, class, and etc.
Therefore I come to which-func-functions, and put the following code for ess-mode, however, it doesn't work.
What hould the function in the list of which-func-functions return?
(defun ess-r--which-function ()
"goto function name"
(save-excursion
(cond
((ess-beginning-of-function t)
(goto-char (ess-beginning-of-function t))
(if (looking-at "[[:space:]]*\\(?1:.*?\\)[[:space:]]*<-")
(match-string-no-properties 1)))
)))
(add-to-list 'which-func-functions 'ess-r--which-function)
Best Regards,
Shuguang
