* lisp/textmodes/ispell.el (ispell-program-name): Add “enchant”.
(ispell-really-enchant): Add variable.
(ispell-check-version): If using Enchant, check it’s new enough (at
least 1.6.1). (Like the ispell check, this is absolute: cannot work
without.)
(ispell-enchant-dictionary-alist): Add variable.
(ispell-find-enchant-dictionaries): Add function, based on
ispell-find-aspell-dictionaries.
(ispell-set-spellchecker-params): Allow dictionary auto-detection for
Enchant, and call ispell-find-enchant-dictionaries to find them. Use
old ispell name to locale mapping code for Enchant too.
(ispell-send-replacement): Make it work with Enchant.
* lisp/simple.el (async-shell-command-display-buffer): Add
defcustom.
(shell-command): Use the new defcustom to determine whether to show
the buffer immediately, or add a process filter that shows it only
when there is some output.
* etc/NEWS: Document the new variable.
* doc/emacs/misc.texi: Likewise.
Thanks to Juri Linkov and Eli Zaretskii for advice and guidance.
* src/xdisp.c (get_overlay_strings_1)
(handle_single_display_spec, push_prefix_prop): Invalidate the
composition information before starting to iterate on a string.
Otherwise we might think in set_iterator_to_next that we are
delivering characters from a composition, and do all kinds of
nonsensical things, like over-step the string end. (Bug#27761)
* lisp/files.el (basic-save-buffer-2, move-file-to-trash):
Use make-temp-name, not make-temp-file with retry.
(basic-save-buffer-2): Use condition-case, instead of
unwind-protect with a success flag.
* lisp/progmodes/grep.el (grep-mode-font-lock-keywords): Allow for NUL
characters following filename in grep context lines.
(grep--regexp-alist-column, grep--regexp-alist-bin-matcher)
(grep-with-null-regexp-alist, grep-fallback-regexp-alist): Remove.
(grep-regexp-alist): Recombine their contents here.
(grep-mode):
* lisp/cedet/semantic/symref/grep.el
(semantic-symref-parse-tool-output-one-line):
* lisp/progmodes/xref.el (xref-collect-matches): Use the variable
`grep-regexp-alist' rather than the function.
Prompted by a problem report by Alex in:
http://lists.gnu.org/archive/html/emacs-devel/2017-08/msg00143.html
* src/eval.c (For, Fprogn, Fsetq, FletX, eval_sub):
Compute XCDR (x) near XCAR (x); although this doesn't fix any bugs,
it is likely to run a bit faster with typical hardware caches.
(Fif): Use Fcdr instead of XCDR, to avoid crashing on
self-modifying S-expressions.
(Fsetq, Flet, eval_sub): Count the number of arguments as we go
instead of trusting an Flength prepass, to avoid problems when the
code is self-modifying.
(Fquote, Ffunction, Fdefvar, Fdefconst): Prefer !NILP to CONSP
where either will do. This is mostly to document the fact that
the value must be a proper list. It's also a tiny bit faster on
typical machines nowadays.
(Fdefconst, FletX): Prefer XCAR+XCDR to Fcar+Fcdr when either will do.
(eval_sub): Check that the args are a list as opposed to some
other object that has a length. This prevents e.g. (if . "string")
from making Emacs dump core in some cases.
* test/src/eval-tests.el (eval-tests--if-dot-string)
(eval-tests--let-with-circular-defs, eval-tests--mutating-cond):
New tests.
The mailcap minibuffer completion used dynamic binding. Locally set
a dynamic variable.
* lisp/dired-aux.el: Store list of files in
`minibuffer-completion-table'.
This action might delete directories containing valuable information.
Before previous commit, we prompted users with `yes-or-no-p'
which doesn't TAB complete the user answer. Let's play safe and
keep requiring full answers.
* emacs-master/lisp/dired.el (dired-delete-file): Use `read-string'
instead of `completing-read' to read the user answers.
* lisp/dired.el (dired-delete-file): Accept 2 additional answers:
'all', to delete all directories recursively and no prompt anymore.
'quit', to cancel directory deletions (Bug#27940).
Show help message when user inputs 'help'.
(dired-do-flagged-delete): Bind locally dired-recursive-deletes
so that we can overwrite its global value.
Wrapp the loop within a catch '--delete-cancel to catch when
the user abort the directtry deletion.
* doc/emacs/dired.texi (Dired Deletion): Update manual.
* etc/NEWS (Changes in Specialized Modes and Packages in Emacs 26.1):
Announce this change.
* lisp/emacs-lisp/autoload.el (autoload--save-buffer):
* lisp/emacs-lisp/bytecomp.el (byte-compile-file):
Use make-temp-file, not make-temp-name, to avoid an unlikely race
that could lose data. Remove the deletion hook as quickly as
possible after the file is renamed; though a race still remains
here, it is smaller than before.
Positions might change if the length of one dired header line
changes; this happen, for instance, if we add new files.
Instead, line numbers are invariant under shrinks/enlargements
of the file header.
https://lists.gnu.org/archive/html/emacs-devel/2017-07/msg01092.html
* lisp/dired.el (dired-save-positions): Save the line numbers at point.
(dired-restore-positions): Use forward-line to restore the original
position (Bug#27968).
* test/lisp/dired-tests.el (dired-test-bug27968): Add test.
Respect comment-auto-fill-only-comments when auto-filling and a
comment syntax is defined.
* lisp/newcomment.el (comment-indent-new-line): Do not check
comment-auto-fill-only-comments.
* lisp/simple.el (internal-auto-fill): New defun.
* src/cmds.c (internal_self_insert): Call Qinternal_auto_fill, not
auto_fill_function.
(syms_of_cmds): Define Qinternal_auto_fill.
* lisp/ruler-mode.el (ruler-mode-ruler, ruler-mode-window-col):
* lisp/emacs-lisp/tabulated-list.el (tabulated-list-init-header)
(tabulated-list-print-entry): Account for the width taken by
line-number display. (Bug#27895)
* src/buffer.c (Fgenerate_new_buffer_name): Test IGNORE for being
nil before calling string-equal, since the latter will compare
"nil and 'nil' as equal. (Bug#27966)
* test/src/buffer-tests.el
(test-generate-new-buffer-name-bug27966): New test.
* lisp/faces.el (describe-face): Return (buffer-string). Reorder
the placement of variables/faces in describe-symbol, to put more
emphasis on the variable entry rather than the face. (Bug#24543)
This incorporates:
2017-08-04 manywarnings: port to 64-bit GCC builds of Emacs
2017-08-01 manywarnings: port to 32-bit GCC bug
* lib/gnulib.mk.in: Regenerate.
* m4/manywarnings.m4: Copy from gnulib.
This function must return non-nil for a wildcard like '/*/*.txt'.
* lisp/files.el (insert-directory-wildcard-in-dir-p): Adjust regexp.
* test/lisp/files-tests.el (files-tests--insert-directory-wildcard-in-dir-p):
Add test.
* test/lisp/emacs-lisp/map-tests.el (test-map-elt-testfn)
(test-map-put-testfn-alist): Make sure the lookup key is really non-eq
to the map's key, even if the code is compiled.
Skip the test if Dired use 'ls' emulation with lisp. The same
bug is tested in their respective test suites: ls-lisp-tests.el
and em-ls-tests.el.
* test/lisp/dired-tests.el (dired-test-bug27631): Skip test if 'ls-lisp'
or 'eshell' features are enabled.
* test/lisp/dired-tests.el (dired-test-bug25609): On MS-Windows,
pass temporary files through file-truename, to avoid bogus
failures due to file-name comparison as strings.
https://lists.gnu.org/archive/html/emacs-devel/2017-08/msg00018.html
* test/lisp/vc/ediff-ptch-tests.el (ediff-ptch-test-bug26084):
Add comments to explain the test logic.
Pass '--binary' option to 'patch' program in windows environments.
Check explicitely that a backup is created before compare file contents.
* test/lisp/dired-tests.el (dired-test-bug25609):
Declare variable 'dired-dwim-target' right before the test.
Add comments to explain the test logic.
Ensure, before test the bug condition, that we are displaying the
2 dired buffers created in this test, and no other dired buffer
is shown.
Problem reported by Glenn Morris (Bug#27708#58).
* src/gnutls.c (HAVE_GNUTLS_X509_SYSTEM_TRUST):
New macro. Use it instead of low-level version number checks.
(HAVE_GNUTLS_AEAD): Move here from gnutls.h, and rename from
HAVE_GNUTLS3_AEAD. All uses changed. Indent preprocessor lines.
* src/gnutls.h (HAVE_GNUTLS3_CIPHER, HAVE_GNUTLS3_DIGEST)
(HAVE_GNUTLS3_HMAC): Remove, since these were available
before GnuTLS 3.0.0 and the code checks them only if HAVE_GNUTLS3
is defined. Remove all uses; this simplifies the code a bit.
Problem reported by Ted Zlatanov in:
http://lists.gnu.org/archive/html/emacs-devel/2017-08/msg00082.html
* src/fileio.c (Frename_file): On RHEL 7 + NFS, renameat2 can fail
with errno == EINVAL when it is not supported. So treat that case
like errno == ENOSYS. Also, when ok_if_already_exists is neither
nil nor an integer, just call plain rename; this avoids an extra
syscall to renameat2 when the latter fails with errno == EINVAL or
ENOSYS or ENOENT.
There's only one GnuTLS, so configuring these symbols at
'configure' time is overkill. Simplify things by moving their
configuration to src/gnutls.h (Bug#27708).
* configure.ac (HAVE_GNUTLS3, HAVE_GNUTLS3_HMAC, HAVE_GNUTLS3_AEAD)
(HAVE_GNUTLS3_CIPHER, HAVE_GNUTLS3_DIGEST): Move these definitions
from here ...
* src/gnutls.h: ... to here, and simplify.
* Makefile.in (configure, bootstrap): Run ‘./autogen.sh autoconf’,
not plain ‘./autogen.sh’, to make it clear that only
autoconf-related tools should be run here.
