show hidden files in speedbar

Question

Is there a way to display what the docs call level 2 hidden files in the speedbar? E.g. .emacs

Long Answer

It turns out that the unshown files are controlled by a regular expression

Which is usually "^\\(\\..*\\)\\'", which I think means everything that starts with a dot

Setting that regexp with:

(setq speedbar-directory-unshown-regexp "^$")

does the trick of showing everything.

Answer 1

While looking at this, I discovered that there is a bug in the default value of speedbar-directory-unshown-regexp causing the problem. It should be redefined like this:

(setq speedbar-directory-unshown-regexp "^\\(CVS\\|RCS\\|SCCS\\|\\.\\.*$\\)\\'")

or to whatever you think makes the most sense.
