isearch-regexp-in-all-matching-files-in-tree?

[Thomas L Roche]

Use case: I'm in a dired buffer in GNU Emacs 21.1.1 on w2k. I
want to _interactively_ search for the string 'GenericAction'
(and replace with 'ActionClass') in all files with names matching
'*.java' anywhere in the directory tree below the current
directory. 

How can I do this?

No, because it requires marking the matching files first, but if
there's a way to do that, I could (manually) chain the two
operations.

Alternatively, is there a way that I could query-replace-regexp
on a grep-mode buffer, instead of a dired buffer? I'd be happy if
I could

M-x grep-find RET

find . -type f -print0 -name '*.java'| xargs -0 -e grep -n -e 
'GenericAction' | grep -v 'EGLGenericAction' | grep -v 
'GenericActionModel' | grep -v 'GenericActionCodeGenContrib' RET

Q RET

GenericAction RET

ActionClass RET

How about

M-x find-dired RET RET -type f -name "*.java"
C-x h
M-x dired-mark-files-in-region
Q GenericAction RET ActionClass RET

C-h f -> "dired-mark-files-regex"

   dired-mark-files-regexp is an interactive compiled Lisp function in
   `dired'.  (dired-mark-files-regexp REGEXP &optional MARKER-CHAR)

   Mark all files matching REGEXP for use in later commands.  A prefix
   argument means to unmark them instead.  `.' and `..' are never
   marked.

   REGEXP is an Emacs regexp, not a shell wildcard.  Thus, use `\.o$'
   for object files--just `.o' will mark more than you might think.

Emacs knows.

M-x find-dired <ret>			# Invoke find-dired
.					# on the current directory
-name '*.java'				# insert the *.java name pattern
-exec grep -q GenericAction {} \;	# edit the grep command

When the find command finishes mark all files as in any dired buffer.

Finally, use A (dired-do-search) to search them interactively.

Hope this helps,
