23.0.60; Dead keys do not work in dired and similar modes in Cocoa port |
|

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the address@hidden
mailing list.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
Dired mode binds ~ to dired-flag-backup-files. When one attempts
entering
~ via the dead-key combination Alt-n (assuming the Alt key is not
used as
a modifier key and Command is interpreted as Meta key), Emacs first
reports
an error message "Buffer is read-only: #<buffer ~>" followed by an error
message "Wrong type argument: overlayp, nil" upon the next event.
In an attempt to fix this issue with some other Emacs version, I have
added
the lines
(define-key function-key-map [dead-tilde] "~")
(put 'dead-tilde 'ascii-character ?~)
to .emacs, but these do not help (nor does removing them from .emacs).
Note that with a German keyboard layout, Alt-n is the only way to
enter a
tilde character. The ASCII tilde is not bound to any key. (Actually, one
could enter ASCII tilde via key combinations Ctrl-Alt-n and Command-
Alt-n,
respectively, but obviously this does not work for Emacs.)
In GNU Emacs 23.0.60.1 (powerpc-apple-darwin8.11.0, NS apple-
appkit-824.48)

The fix for bug#23412 fixes this. It inserts the working text into the
buffer so you can see what's being typed, but once it completes it
deletes it and dired takes its action. It maybe looks a little weird,
but it works and I'm not sure what else we would do other than just not
display the working text at all.
