which-func/imenu

[Doug Lewan]

Just what do I have to do to make which-function-mode aware of a new language? I haven't been able to entirely disentangle the documentation.

I think I know the following.
* I need imenu.
* I have to create imenu-generic-expression. (My world is simple. I think the value (nil "procedure\\s-+\\(?1:[[:alnum:]]+\\)" 2) should do. But I have been wrong one other time.)
* I need to add the mode (as a symbol) to which-func-modes.

This is, however, not enough to "support Imenu", in the words of emacs Info section 26.2.4.
What should I really be doing?

imenu--index-alist is in the center of things here.
If it gets filled,  which-func-modes should work right out of the box.

Thanks. I'll give it a try.
