Imenu in speedbar

Question

The documentation to Imenu states:

Imenu provides the information to guide Which Function mode (see Which Function Mode). The Speedbar can also use it

My questions is: How do I add imenu entries to the speedbar?

Answer 1

To add support for Markdown, eval:

(require 'speedbar)
(speedbar-add-supported-extension ".md")

Usually, you don't have to worry about this:
Speedbar (smartly) handles this automatically.

For example, there's a Python file a.py on my ~/Desktop:

def f():
    pass
class C:
    def m1(self):
        pass
    def m2(self):
        pass
def g():
    pass

Simply launch Emacs by emacs -Q and type M-x speedbar. You can see there is a + sign before the filename:

Click at the + sign and you'll see the declaration list as shown in the imenu:
