Use shell-quote-wildcard-pattern on the switches string split by
split-string-and-unquote. This helps to quote such switches as
"--block-size='1" (bug#71935).
* lisp/dired.el (dired-jump): Disable dired-omit-mode with -1.
* lisp/files.el (recover-session): Disable dired-omit-mode
explicitly afterwards instead of modifying dired-mode-hook
that fails when it contains a lambda.
Make it possible to provide more dir-local variables, such as
done by the Editorconfig package.
* lisp/files.el (hack-dir-local--get-variables): Make arg optional.
(hack-dir-local-get-variables-functions): New hook.
(hack-dir-local-variables): Run it instead of calling
`hack-dir-local--get-variables`.
* doc/lispref/variables.texi (Directory Local Variables):
Document the new hook.
* doc/lispref/backups.texi (Reverting):
Add documentation for 'revert-buffer-restore-functions'.
* lisp/files.el (revert-buffer-restore-functions): New variable.
(revert-buffer-restore-read-only): New function.
(revert-buffer): Use 'revert-buffer-restore-functions' with
the default value 'revert-buffer-restore-read-only' (bug#69511).
* lisp/buff-menu.el (Buffer-menu-mode): Add hook
'revert-buffer-restore-functions' to restore
outline-minor-mode highlighting.
* doc/misc/tramp.texi (Frequently Asked Questions): Describe how
to manipulate trash-directory.
Explain tramp-inhibit-errors-if-setting-file-attributes-fail.
* lisp/files.el (move-file-to-trash): Use connection-local value
of `trash-directory'. (Bug#70421)
The old code tested if the mode function is `fboundp` but in an
inconsistent way and without paying attention to
`major-mode-remap`.
* lisp/files.el (set-auto-mode-0): Return `:keep` rather than nil if
the mode was already set. And emit a warning when the mode function
doesn't exist.
(set-auto-mode): Remove checks that the mode function exists now that
`set-auto-mode-0` does it for us. Adjust to the new return values of
that function, and simplify the code using a big `or` instead of
a sequence of steps each setting&testing `done`.
(hack-local-variables--find-variables): Use `major-mode-remap`
when skipping the "mode:" entries that specify modes we don't have.
Also, when (eq handle-mode t), don't bother building a list of results
only to return a single element in the end.
While `major-mode-remap-alist` provides a way for users to indicate the
major mode of their choice, we need a similar variable for the
use of packages.
This patch adds a new `major-mode-remap-defaults` and changes various
packages to obey it or make use of it.
I think it nicely cleans the regexp duplication between CC-mode and
`c-ts-mode.el` and also makes it easier/cleaner for users to override
the changes made by `*-ts-mode.el`.
* lisp/files.el (major-mode-remap-defaults): New variable.
(major-mode-remap): New function.
(set-auto-mode-0): Use it.
* doc/lispref/modes.texi (Auto Major Mode): Document them.
* lisp/textmodes/tex-mode.el (tex--redirect-to-submode):
Use `major-mode-remap`.
(major-mode-remap-defaults): Set it to remap AUCTeX modes by default.
* lisp/progmodes/ruby-ts-mode.el (auto-mode-alist): Leave it alone.
(major-mode-remap-defaults): Set this one instead.
* lisp/progmodes/c-ts-mode.el (c-or-c++-ts-mode): Use `major-mode-remap`.
(auto-mode-alist): Leave it alone.
(major-mode-remap-defaults): Set this one instead.
* lisp/org/ox.el (org-export-to-buffer): Modernize docstring accordingly.
* lisp/progmodes/cc-mode.el (c-or-c++-mode):
* lisp/org/ox-latex.el (org-latex-export-as-latex):
* lisp/org/ox-koma-letter.el (org-koma-letter-export-as-latex):
* lisp/org/ox-beamer.el (org-beamer-export-as-latex):
Use `major-mode-remap` when available.
For bug#64939.
* lisp/files.el (auto-mode-interpreter-regexp): Account for possible
VARIABLE=[VALUE] operands.
* test/lisp/files-tests.el (files-tests-auto-mode-interpreter):
Add an example from the coreutils manual.
This is not an exact re-implementation of what env accepts, but
hopefully it should be "good enough".
Example of known limitation: we assume that arguments for
--long-options will be set with '=', but that is not
necessarily the case. '--unset' (mandatory argument) can be
passed as '--unset=VAR' or '--unset VAR', but
'--default-signal' (optional argument) requires an '=' sign.
For bug#64939.
* lisp/files.el (auto-mode-interpreter-regexp): Account for
supplementary arguments passed beside -S/--split-string.
* test/lisp/files-tests.el (files-tests-auto-mode-interpreter):
Test some of these combinations.
This ensures that overlapping shorthands are handled correctly and
consistently even if specified out-of-order by the user.
* doc/lispref/symbols.texi (Shorthands): Describe shorthand sort
order.
* lisp/files.el (hack-local-variables--find-variables): Specially
handle read-symbol-shorthands.
* files.el (auto-mode-alist): Match non-hidden authinfo and netrc
files, since it is reasonable to store passwords in
~/.emacs.d/authinfo.gpg or a similarly named file. (Bug#66241)
* lisp/files.el (find-buffer-visiting): Fix code branch checking for
buffers referring to the same file number. We should check the found
buffer with the file number, not current.
Link: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=66117#412
* src/buffer.c (Fget_truename_buffer): Expose `get_truename_buffer' to
Elisp.
(Ffind_buffer): New subr searching for a live buffer with a given
value of buffer-local variable.
(syms_of_buffer): Register the new added subroutines.
* src/filelock.c (lock_file): Use the new `Fget_truename_buffer' name.
* src/lisp.h:
* test/manual/etags/c-src/emacs/src/lisp.h: Remove no-longer-necessary
extern declarations for `get_truename_buffer'.
* lisp/files.el (find-buffer-visiting): Refactor, using subroutines to
search for buffers instead of slow manual Elisp iterations.
* lisp/files.el (recover-file): Show diff against the selected auto
save file. (Bug#52242)
* doc/emacs/files.texi (Recover): Document the new feature.
* etc/NEWS: Announce the new feature.
Rather than have `ls-lisp` advise `insert-directory`, make
`insert-directory` call `ls-lisp.el` code directly when needed.
* lisp/files.el (files--use-insert-directory-program-p): New function.
(insert-directory): Use it to delegate to `ls-lisp--insert-directory`
when applicable.
* lisp/ls-lisp.el (ls-lisp--insert-directory): Remove `orig-fun` arg.
Don't test `ls-lisp-use-insert-directory-program` or check for a magic
file name handler; it is now the caller's responsibility.
(insert-directory): Don't add advice any more.
* lisp/dired.el (ls-lisp-use-insert-directory-program): Don't declare it.
(dired-insert-directory): Use `files--use-insert-directory-program-p` instead.
(dired-use-ls-dired): Adjust docstring to refer to
`insert-directory-program` rather than "ls".
The bug was encountered via the ls-lisp advice on Dired but
it actually affects all uses of `file-expand-wildcards`,
so better fix it there.
* lisp/files.el (file-expand-wildcards): Fix bug#60819.
* lisp/ls-lisp.el (ls-lisp--dired): Undo commit b365a7cc32.
* test/lisp/files-tests.el (files-tests--expand-wildcards): New test.
E.g. (file-expand-wildcards "/u*/*m*")
returned ("/usr/games" "/u/dummy" "/u/monnier" "/u/omnibook-disk")
instead of ("/u/dummy" "/u/monnier" "/u/omnibook-disk" "/usr/games").
* etc/NEWS: announce the change.
* lisp/files.el (auto-mode-interpreter-regexp): Add optional '-S'
switch to the ignored group capturing the env invocation.
Allow multiple spaces between #!, interpreter and first argument:
empirically, Linux's 'execve' accepts that. (Bug#66902)
* test/lisp/files-tests.el (files-tests--check-shebang): New helper to
generate a temporary file with a given interpreter line, and assert
that the mode picked by 'set-auto-mode' is derived from an expected
mode. Write the 'should' form so that failure reports include useful
context; for example:
(ert-test-failed
((should
(equal (list shebang actual-mode) (list shebang expected-mode)))
:form
(equal ("#!/usr/bin/env -S make -f" fundamental-mode)
("#!/usr/bin/env -S make -f" makefile-mode))
:value nil :explanation
(list-elt 1 (different-atoms fundamental-mode makefile-mode))))
* test/lisp/files-tests.el (files-tests-auto-mode-interpreter): New
test; exercise some aspects of 'interpreter-mode-alist'.
Try and avoid using the `derived-mode-parent` property directly
and use the new API functions instead.
* lisp/emacs-lisp/derived.el (define-derived-mode):
Use `derived-mode-set-parent`.
* lisp/loadhist.el (unload--set-major-mode):
* lisp/info-look.el (info-lookup-select-mode):
* lisp/ibuf-ext.el (ibuffer-list-buffer-modes):
* lisp/files.el (dir-locals--get-sort-score):
* lisp/emacs-lisp/cl-generic.el (cl--generic-derived-specializers):
Use `derived-mode-all-parents`.
* lisp/files.el (basic-save-buffer-2): Call 'set-file-modes' to
try to make the file writable, even if
'set-file-extended-attributes' succeeded. (Bug#66546)
