Inlining these trivial functions gives a healthy speed boost to many
common functions such as `sort`, `mapcar` etc.
* src/eval.c (call0, ..., call8): Move functions...
* src/lisp.h (call0, ..., call8): ...here and declare them inline.
Since <, <=, > and >= have their own byte-ops, the corresponding
functions are mostly used as arguments to higher-order functions.
This optimisation is particularly beneficial for sorting, where the
comparison function is time-critical.
* src/data.c (Flss, Fgtr, Fleq, Fgeq):
* src/fileio.c (Fcar_less_than_car):
Fast path for calls with 2 fixnum arguments.
Since string-lessp has its own byte-op, using it is much faster than
calling string-greaterp even with the need to bind a temporary
variable.
* lisp/emacs-lisp/byte-opt.el (byte-optimize-string-greaterp): New.
(string-greaterp, string>): Set byte-optimizer.
Since this function is commonly used as a sorting predicate
where it is time-critical, this is a useful optimisation.
* src/fns.c (Fstring_lessp): Add fast path for the common case
when both arguments are unibyte.
* test/src/fns-tests.el (fns-tests--string-lessp-cases)
(fns-tests-string-lessp): New test.
* xterm.c (struct x_client_list_window): New fields for frame
extents.
(x_dnd_compute_toplevels): Set window frame extents.
(x_dnd_get_target_window_1): Return None if the mouse is in a
frame extent.
(x_dnd_get_target_window): Likewise.
* doc/lispref/frames.texi (Drag and Drop): Document new meaning
of `return-frame' in `x-begin-drag'.
* lisp/mouse.el (mouse-drag-and-drop-region): Use `now' when
calling `x-begin-drag'.
* src/xfns.c (Fx_begin_drag): Update doc string.
* src/xterm.c (x_dnd_begin_drag_and_drop): Accept return_frame
as a Lisp_Object and handle Qnow correctly.
(XTmouse_position): Ignore tooltip frames when processing
`drag-source'.
(syms_of_xterm): New defsym `now'.
* src/xterm.h: Update prototypes.
Add a new `record_unwind_protect_ptr_mark` function for use with C data
structures that use the specpdl for clean-up but also contain possibly
unique references to Lisp objects.
* src/eval.c (record_unwind_protect_ptr_mark): New.
(record_unwind_protect_module, set_unwind_protect_ptr):
Set the mark function to NULL.
(mark_specpdl): Call the mark function if present.
* src/lisp.h (unwind_ptr): Add a mark function pointer to the
SPECPDL_UNWIND_PTR case.
Previously, Eshell would get confused and think the following command
was unterminated due to the second double-quote looking like it was
escaped:
echo "\\"
* lisp/eshell/esh-util.el (eshell-find-delimiter): Correct docstring
and treat '\' as an escapeable character when using backslash escapes.
* test/lisp/eshell/eshell-tests.el
(eshell-test/escape-special-quoted): Adapt test.
* lisp/emacs-lisp/easy-mmode.el (easy-mmode--arg-docstring): Allow
saying whether it's a global minor mode or not.
(easy-mmode--mode-docstring): Use it.
(define-minor-mode): Pass in the data.
* doc/lispref/frames.texi (Mouse Tracking):
* etc/NEWS: Announce new `drag-source' value of `track-mouse'.
* lisp/mouse.el (mouse-drag-and-drop-region): Use new value of
`track-mouse' during interprogram drag and drop.
* src/keyboard.c (make_lispy_position): Handle nil values of f
correctly.
* src/xdisp.c (define_frame_cursor1): Ignore if `drag-source' as
well.
(syms_of_xdisp): New defsym `drag-source'.
* src/xterm.c (XTmouse_position): Implement `drag-source'.
(mouse_or_wdesc_frame): Likewise.
* lisp/term/haiku-win.el (haiku-drag-and-drop): Handle special
drag and drop motion events.
* src/haiku_support.cc (MouseMoved): Set `dnd_message' flag.
* src/haiku_support.h (struct haiku_mouse_motion_event): New
member `dnd_message'.
* src/haikuterm.c (haiku_read_socket): Create special DND events
when the mouse moves with a drop message.
* doc/emacs/frames.texi (Drag and Drop):
* etc/NEWS: Document new options 'dnd-scroll-margin' and
'dnd-indicate-insertion-point'.
* lisp/dnd.el (dnd-protocol-alist):
(dnd-open-remote-file-function):
(dnd-open-file-other-window): Add right group to defcustoms.
(dnd-scroll-margin, dnd-indicate-insertion-point): New user
options.
(dnd-handle-movement): New function.
* lisp/x-dnd.el (x-dnd-handle-xdnd):
(x-dnd-handle-motif): Call `dnd-handle-movement' when
appropriate.
* lisp/subr.el (ensure-empty-lines, string-lines): Moved from
subr-x so that they can be used in early bootstrap files.
* lisp/emacs-lisp/easy-mmode.el (easy-mmode--mode-docstring):
Don't use string-empty-p because of bootstrap issues.
* lisp/eshell/em-extpipe.el (em-extpipe--or-with-catch): New macro.
(eshell-parse-external-pipeline): Use new macro to treat
`eshell-incomplete' as a failure of the parse function to move us
forward (Bug#54603). Thanks to Jim Porter <jporterbugs@gmail.com> for
the report and for help isolating the problem.
* test/lisp/eshell/eshell-tests.el
(eshell-test/lisp-command-with-quote): New test for Bug#54603, thanks
to Jim Porter <jporterbugs@gmail.com> (bug#54603).
This happens when dropping files from dtfile, which somehow puts
non-atom stuff in window properties of type ATOM_PAIR.
* src/xselect.c (x_atom_to_symbol): Catch errors around
XGetAtomName.
* etc/NEWS: Announce new user option.
* lisp/mouse.el (mouse-drag-and-drop-region-scroll-margin): New

(x_dnd_update_state, handle_one_xevent): Send toplevel leave
along with drops.
Merge the old lambda+list into a single OClosure object which plays
both roles at the same time. Take advantage of it to provide a
`cl-print-object` method so kmacro objects print nicely using the
`key-parse` syntax.
Also replace the old `kmacro-lambda-form` with a new `kmacro` constructor
which takes a `key-parse` syntax, so that the code inserted with
`insert-kbd-macro` is now more readable.
* lisp/kmacro.el (kmacro): New OClosure type.
(kmacro-ring-head): Use `kmacro` constructor.
(kmacro-push-ring): Convert `elt` from old representation if needed.
(kmacro-split-ring-element, kmacro-view-ring-2nd, kmacro-view-macro):
Adapt to new representation.
(kmacro-exec-ring-item): Turn into obsolete alias.
(kmacro-call-ring-2nd, kmacro-end-or-call-macro): Adjust accordingly.
(kmacro-start-macro): Simplify call to `kmacro-push-ring`.
(kmacro): New constructor function. Replaces `kmacro-lambda-form`.
(kmacro-lambda-form): Use it and declare obsolete.
(kmacro-extract-lambda): Rewrite and declare obsolete.
(kmacro-p): Rewrite.
(cl-print-object): New method.
(kmacro-bind-to-key, kmacro-name-last-macro): Simplify.
* lisp/macros.el (macro--string-to-vector): New function.
(insert-kbd-macro): Use it. Generate code using the `kmacro` constructor.
