I found that emacs speedbar does not show all the type of files
Especially, .bin files does not show up in my case
I have tried some settings as below, but it still doesn't work
Do you have any idea for this issue or I'm missing something for the setup
setting #1
(setq sr-speedbar-show-unknown-files t)
(custom-set-variables '(speedbar-show-unknown-files t))
(custom-set-variables '(sr-speedbar-show-unknown-files t))
setting #2
(setq speedbar-add-supported-extension ".bin")
setting #3
(setq speedbar-directory-unshown-regexp "^\(\.\.*$\)\'")
