RE: filter from find-dired

Great. Thanks Drew

what I needed was 'default-directory'

That simplifies my previous problem to

(defun find-substitutions ()
   "find substitution files in the current directory"
   (interactive)
   (find-name-dired (default-directory) "*substitutions*")
   )

I would like to filter the entries under ".svn" directories, so that 
they are not included.

Not sure what you are trying to do. You don't show `get-file-name', 
for one
thing, so your code cannot be evaluated by someone trying to help.

If you are trying to get the (non-)directory component of an absolute 
file name,
consider using `file-name-(non)directory'.

When you ask for improvement suggestions, I recommend that you start 
by saying
what your code is intended to do. Sometimes a completely different
implementation might be suggested, but only if someone can tell what 
you are
really trying to do.

Looking at just your doc string (which might be inaccurate), it would 
seem that
all you need is `default-directory'. That _is_ "the current 
directory".

If you need that added to the kill buffer, then (kill-new default-
directory)
should be adequate.

Hi again,

get-directory-name is my function too. Glad to receive suggestions on 
how to improve it.

(defun get-directory-name ()
  "return the current directory"
  (interactive)
  (let (dirname components)
    (if (null (buffer-file-name (current-buffer)))
        (setq dirname (expand-file-name default-directory))
      (setq components (butlast (split-string (get-file-name) "/")))
      (setq dirname (mapconcat 'identity components "/"))
      )
    (message dirname)
    (kill-new dirname)
    dirname)
)

Subject: filter from find-dired

Hello

I created a helper interactive function for my work that searches 
files from the current
directory that match the name "*subst*".

(defun find-substitutions ()
  "find substitution files in the current directory"
  (interactive)
  (find-name-dired (get-directory-name) "*substitutions*")
  )

I would like to filter the entries that sit under a .svn directory

How would I go about it?

In "plain" find, I found this works

find . -name .svn -prune -o -name "*subst*" -print 

find-dired with the same parameters does not filter the entries under
.svn, instead it includes all .svn directories

Thanks
