* lisp/textmodes/css-mode.el (css-smie-grammar): Give colons belonging
to properties higher precedence.
(css--colon-inside-selector-p, css--colon-inside-funcall): New
functions for helping SMIE during tokenization.
(css-smie--forward-token, css-smie--backward-token): Distinguish
colons belonging to properties from other colons.
* test/manual/indent/css-mode.css: Add tests for the changes above.
* test/manual/indent/scss-mode.scss: Ditto.
* lisp/emacs-lisp/edebug.el (edebug-max-depth): Add defcustom.
(Bug#24713)
* etc/NEWS: Mention edebug-max-depth.
* doc/lispref/edebug.texi (Checking Whether to Stop): Mention
edebug-max-depth and index it. Add cross-references for
max-lisp-eval-depth and max-specpdl-size.

* lisp/dired.el (dired-listing-switches): Document how to quote
options with embedded whitespace.
* lisp/files.el (insert-directory): Use split-string-and-unquote
to support dired-listing-switches that specify command-line
options with embedded spaces. (Bug#25485)
Make the existing if-let and when-let aliases.
* lisp/emacs-lisp/subr-x.el (if-let*, when-let*): New macros. Rewrite
docstrings, incorporating that from let* and the existing if-let.
(if-let, when-let, and-let*): Alias them.
alloc.c had bitrotted a bit, and used an undefined symbol
stack_base when Emacs was built on Solaris sparc, leading to
compilation failures. Also, code related to __builtin_unwind_init
was unnecessarily duplicated. Fix the bitrot and remove some
duplication.
* src/alloc.c: Remove uses of GC_SAVE_REGISTERS_ON_STACK, since it
is never defined.
(test_setjmp) [!HAVE___BUILTIN_UNWIND_INIT && GC_SETJMP_WORKS]:
Define a no-op dummy, to simplify use.
(test_setjmp) [!GC_SETJMP_WORKS]: Test setjmp_tested_p here rather
than in the caller, to simplify use.
(stacktop_sentry): New type.
(__builtin_unwind_init) [!HAVE___BUILTIN_UNWIND_INIT]: New macro.
(SET_STACK_TOP_ADDRESS): New macro, containing code that was duplicated.
(flush_stack_call_func, Fgarbage_collect): Use it.
(init_alloc): Omit unnecessary initialization.
After dumping, Emacs need not re-test setjmp.
* src/xdisp.c (partial_line_height): New function.
(try_scrolling):
* src/window.c (window_scroll_pixel_based): Use it for calculating the
pixel scroll margin correctly in a window with partial lines.
* src/xdisp.c (maximum-scroll-margin): New variable.
* lisp/cus-start.el: Make it customizable.
* etc/NEWS: Mention it.
* doc/emacs/display.texi (Auto Scrolling):
* doc/lispref/windows.texi (Textual Scrolling): Document it.
* src/window.c (window_scroll_pixel_based): Use it instead of hardcoding
division by 4 (Bug #5718).
Its effective range needs to be clamped between 0 and (window height /
4), so it's better to have this constraint in a single place.
* src/window.c (window_scroll_margin): New function.
(window_scroll_pixel_based, window_scroll_line_based):
(Frecenter, Fmove_to_window_line):
* src/xdisp.c (try_scrolling, try_cursor_movement):
(redisplay_window, try_window, try_window_id): Use it.
* src/lisp.h (STACK_CONS, AUTO_STRING_WITH_LEN):
Parenthesize compound literals that are function call args.
Although this does not fix any bugs, it is the proper style for
macro parenthesization as it means this code will continue to
work even if make_lisp_ptr is changed to a macro.
2017-01-30 Port to PGI 16.10 x86-64
2017-01-20 time_rz: fix comment typo
2017-01-14 strftime: %z is -00 if unknown
This incorporates:
* doc/misc/texinfo.tex, lib/c-ctype.h, lib/strftime.c:
* lib/time-internal.h, lib/verify.h:
Copy from gnulib.
* lisp/replace.el (list-matching-lines-current-line-face)
(list-matching-lines-jump-to-current-line): New user options.
(occur--orig-line, occur--orig-line-str): New variables.
(occur, occur-engine): Use them.
(occur--final-pos): New variable.
(occur-1): Use it.
(occur-engine): Idem.
Show the current line with 'list-matching-lines-current-line-face'.
Set point on the first matching line after the current one.
* etc/NEWS: Add entry for the new option.
Another step in the long history of list-buffers-directory. A thread
branch discussing the meaning/use of the variable starts here
https://lists.gnu.org/archive/html/emacs-devel/2009-09/msg00684.html
Also see (info "(elisp) Buffer File Name").
* lisp/buff-menu.el: Relocate special case code into info.el. Nix
Info-* defvars.
(Buffer-menu--pretty-file-name): Remove special case. Use
bound-and-true-p.
(Buffer-menu-info-node-description): Remove.
* lisp/ibuffer.el (ibuffer-buffer-file-name): Treat
list-buffers-directory as a string.
* lisp/info.el (Info-node-description): New function.
(Info-select-node): Use it.
With the previous defaults, doing image-dired on a directory with an
animated foo.gif would cause creation of foo.thumb-N.gif for each of
N frames in foo.gif. By default image-dired looks for foo.thumb.gif, so
there additionally is no usable thumbnail after all the needless effort.
image-dired never handled animation, regardless.
* lisp/image-dired.el: Mention limitation.
(image-dired-cmd-create-thumbnail-options):
(image-dired-cmd-create-temp-image-options):
(image-dired-cmd-create-standard-thumbnail-options): Append [0] to
filename to indicate only converting the 0th frame.
(image-dired-display-image-mode): Don't show a cursor.
Problem noted by Eli Zaretskii in:
http://lists.gnu.org/archive/html/emacs-devel/2017-01/msg00721.html
This patch also fixes some other issues in that report.
* src/lisp.h (incr_rarely_quit): Remove.
All callers changed to use rarely_quit directly.
* src/search.c (freeze_buffer_relocation)
(thaw_buffer_relocation): New functions.
(looking_at_1, fast_looking_at, search_buffer):
Use them to fix bug when quitting when buffers are frozen.
* src/sysdep.c (emacs_intr_read): Rename from emacs_nointr_read.
All uses changed.
This fixes some infinite loops that cannot be quitted out of,
e.g., (defun foo () (nth most-positive-fixnum '#1=(1 . #1#)))
when byte-compiled and when run under X. See:
http://lists.gnu.org/archive/html/emacs-devel/2017-01/msg00577.html
This also attempts to keep the performance improvements I recently
added, as much as possible under the constraint that the infloops
must be caught. In some cases this fixes infloop bugs recently
introduced when I removed immediate_quit.
* src/alloc.c (Fmake_list):
Use rarely_quit, not maybe_quit, for speed in the usual case.
* src/bytecode.c (exec_byte_code):
* src/editfns.c (Fcompare_buffer_substrings):
* src/fns.c (Fnthcdr):
* src/syntax.c (scan_words, skip_chars, skip_syntaxes)
(Fbackward_prefix_chars):
Use rarely_quit so that users can C-g out of long loops.
* src/callproc.c (call_process_cleanup, call_process):
* src/fileio.c (read_non_regular, Finsert_file_contents):
* src/indent.c (compute_motion):
* src/syntax.c (scan_words, Fforward_comment):
Remove now-unnecessary maybe_quit calls.
* src/callproc.c (call_process):
* src/doc.c (get_doc_string, Fsnarf_documentation):
* src/fileio.c (Fcopy_file, read_non_regular, Finsert_file_contents):
* src/lread.c (safe_to_load_version):
* src/sysdep.c (system_process_attributes) [GNU_LINUX]:
Use emacs_read_quit instead of emacs_read in places where
C-g handling is safe.
* src/eval.c (maybe_quit): Move comment here from lisp.h.
* src/fileio.c (Fcopy_file, e_write):
Use emacs_write_quit instead of emacs_write_sig in places where
C-g handling is safe.
* src/filelock.c (create_lock_file): Use emacs_write, not
plain write, as emacs_write no longer has a problem.
(read_lock_data): Use emacs_read, not read, as emacs_read
no longer has a problem.
* src/fns.c (rarely_quit): Move to lisp.h and rename to
incr_rarely_quit. All uses changed..
* src/fns.c (Fmemq, Fmemql, Fassq, Frassq, Fplist_put, Fplist_member):
* src/indent.c (compute_motion):
* src/syntax.c (find_defun_start, back_comment, forw_comment)
(Fforward_comment, scan_lists, scan_sexps_forward):
Use incr_rarely_quit so that users can C-g out of long loops.
* src/fns.c (Fnconc): Move incr_rarely_quit call to within
inner loop, so that it catches C-g there too.
* src/keyboard.c (tty_read_avail_input): Remove commented-out
and now-obsolete code dealing with interrupts.
* src/lisp.h (rarely_quit, incr_rarely_quit): New functions,
the latter moved here from fns.c and renamed from rarely_quit.
(emacs_read_quit, emacs_write_quit): New decls.
* src/search.c (find_newline, search_buffer, find_newline1):
Add maybe_quit to catch C-g.
* src/sysdep.c (get_child_status): Always invoke maybe_quit
if interruptible, so that the caller need not bother.
(emacs_nointr_read, emacs_read_quit, emacs_write_quit):
New functions.
(emacs_read): Rewrite in terms of emacs_nointr_read.
Do not handle C-g or signals; that is now for emacs_read_quit.
(emacs_full_write): Replace PROCESS_SIGNALS two-way arg
with INTERRUPTIBLE three-way arg. All uses changed.
The old code that sets and clears immediate_quit was
ineffective except when Emacs is running in terminal mode, and
has problematic race conditions anyway, so remove it. This
will introduce some hangs when Emacs runs in terminal mode,
and these hangs should be fixed in followup patches.
* src/keyboard.c (immediate_quit): Remove. All uses removed.
This fixes bug #24431. The key change of this bug fix is correctly analyzing
nested brace lists when the opening element stands on the same line as both
its introductory brace and an enclosing parameter list parenthesis.
* list/progmodes/cc-align.el (c-lineup-under-anchor): New line-up function.
* list/progmodes/cc-engine.el (c-looking-at-or-maybe-in-bracelist): Accept the
presence of exactly an identifier between an open parenthesis and an open
brace as evidence of the brace starting a brace list.
(c-looking-at-statement-block): New function, extracted from
c-looking-at-inexpr-block. Enhance it to analyze inner blocks recursively
when needed.
(c-looking-at-inexpr-block): Extract new function (see above) and call it.
(c-add-stmt-syntax): Enhance, with new &optional parameter, to supply the
prime syntactic symbol with a fixed anchor point. When this is used, restrict
all added syntactic symbols to those having an anchor point on the same line.
Add, in addition to the current additional symbols, c-brace-list-entry when
needed; use c-looking-at-statement-block to determine the latter.
(c-guess-basic-syntax, CASE 9D): Use c-add-stmt-syntax rather than just
c-add-syntax, to assemble the syntactic context of a 'brace-list-entry, thus
getting, possibly, several accompanying syntactic entries.
* lisp/progmodes/cc-styles.el (c-style-alist, "gnu" style): New entry for
'brace-list-intro, namely c-lineup-arglist-intro-after-paren.
* lisp/progmodes/cc-vars.el (c-offsets-alist): Change the factory default
offset for 'brace-list-entry from 0 to c-lineup-under-anchor.
* doc/misc/cc-mode.texi (Syntactic Symbols): Amend the definition of
brace-list-intro.
(Brace List Symbols): Amend the example to show the new analysis of brace
lists when the first element comes on the same line as the opening brace.
(Misc Line-Up): Document the new line-up function c-lineup-under-anchor.
This reverts commit d1c9310090.
Not all the cases where we had string-as-unibyte were characters,
so this needs to be considered more thoroughly before being redone.
* lisp/gnus/gnus-art.el (gnus-article-mode-syntax-table): Make
M-. in article buffers work for `foo' strings, and still allow
C-s C-w to yank ' to the search ring (bug#22248).
