The changes to the A/Q bindings in dired as discussed and confirmed are not
immediately compatible on Windows
Ref: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=23426#49
Even understanding that users would need to install GNU find & grep on
their Windows system to use the new implementations bound to A/Q in dired,
I believe that we should have the following:
- NOT bind A/Q at all if the right dependencies are not found. I tried the
A binding on Windows, it looked like it was grepping for the strings I
entered and returned an empty *xref* window. The same search on same files
worked as expected in RHEL (to be honest I love this new feature on RHEL,
and I might start using the A binding). Currently the implementation on
Windows gives an appearance that something was searched for and no results
were found. That is misleading!
Possible solution?
(when (correct-version-of-find-and-grep-found-p)
(define-key dired-mode-map (kbd "A") #'dired-do-find-regexp)
(define-key dired-mode-map (kbd "A") #'dired-do-find-regexp-and-replace))
- Another alternative would be (if we want to keep A/Q bindings) that a
user-error or error be thrown if the correct external dependencies are not
installed. The user should be let known that they need to install the GNU
find/grep executables for their platform in order to use those commands. In
the current implementation, the user will just assume that they searched
something and nothing got returned.
- The requirement to have find/grep installed should also go to backward
incompatible changes section in NEWS.
(I got an idea of "incompatible change" section in NEWS from this recent
commit:
http://git.savannah.gnu.org/cgit/emacs.git/commit/?h=emacs-25&id=c68a09107c1f7459c626d38be5e0e991912e57ec
)
I would suggest that this bug be made blocking for the release of 25.1.
For Windows users, the bindings change for A/Q keys in dired is not
apparent to the user. At the very least, an error should be thrown if the
correct external dependencies (GNU version of find/grep) are not found on
the system PATH.
