.fmt files missing in speedbar

.fmt files missing in speedbar

[jm]

In emacs -Q I evaluate:

    (add-to-list 'auto-mode-alist '("\\.fmt\\'" . html-mode))
    (setq
     speedbar-directory-unshown-regexp "^\(\.\.*$\)\'"
     speedbar-show-unknown-files t)

but browsing a directory in the speedbar containing ‘file.fmt’ files
appears empty. Changing the extension to ‘.FMT’ makes it appear. In fact
I cannot find any other extension that causes a file to not appear; e.g.
‘.file.ext’, ‘file.bonkers’, ‘file.♑’, etc. all show up.

What am I missing here?

You forgot to double your backslashes here, so they only act as string
escapes, not regexp escapes. The actual value of
‘speedbar-directory-unshown-regexp’ is ‘^(..*$)'’, which means “start
of string followed by open parenthesis followed by one or more
non-newline characters followed by end of line followed by close
parenthesis then single quote”. Which ought not match anything.

I have no explanation for this behavior you observe. (I also have no
experience with speedbar.)

Files with extension .fmt are matched by speedbar-file-unshown-regexp,
whose doc string says: "Regexp matching files we don’t want displayed in
a speedbar buffer.  It is generated from the variable
‘completion-ignored-extensions’."

Thanks. I figured it out earlier but think I forgot to CC the list with
the follow up.
