* doc/emacs/display.texi (Horizontal Scrolling): Document the new
mode of auto-hscrolling only the current line.
* src/xdisp.c (init_iterator): When hscrolling only the
current line, apply the window's min_hscroll here, so that
non-current lines will be hscrolled by that minimum.
Suggested by Stephen Berman <stephen.berman@gmx.net>.
(hscroll_window_tree): Account for window's min_hscroll when
deciding whether to recompute the hscroll.
(display_line): Subtract window's min_hscroll from x_incr, as that
was already accounted for in init_iterator. (Bug#27008)
* src/.gdbinit (to_string): Use an unsigned representation for
Lisp values, as requested by Eli Zaretskii (Bug#27098).
Also, use "make_number(N)" for Lisp integers.
Use IN_MASK_ADD instead of using a no-longer-promiscuous-enough
mask. This simplifies the code and restores the ability to
use IN_ACCESS, IN_CLOSE_WRITE, IN_CLOSE_NOWRITE, and IN_OPEN
in some cases (Bug#26973).
* src/inotify.c (INOTIFY_DEFAULT_MASK): Remove.
(Finotify_add_watch): Use IN_MASK_ADD instead.
There was no need to remove it in the 2017-03-26 inotify change,
as it is like IN_DONT_FOLLOW and does not affect other watchers
for the same file.
* src/inotify.c (symbol_to_inotifymask, Finotify_add_watch)
(syms_of_inotify): Bring back onlydir.
* src/inotify.c (add_watch): Accept uint32_t imask instead
of Lisp_Object aspect. Caller changed.
(Finotify_add_watch): Use aspect_to_inotifymask earlier, to
simplify the code.
When configured with --without-ns, HAVE_NS is not defined on macOS,
thus 'memory-limit' calls the deprecated sbrk(2) function. Avoid that
by using the pre-defined __APPLE__ preprocessor macro.
* src/alloc.c (Fmemory_limit): Never use sbrk(2) on macOS.
* src/window.c (Fset_window_scroll_bars): Fix doc-string.
* doc/lispref/display.texi (Fringe Size/Pos, Scroll Bars)
(Display Margins): Mention that `set-window-buffer' may override
settings made by `set-window-fringes', `set-window-scroll-bars'
and `set-window-margins'.
* doc/lispref/windows.texi (Buffers and Windows): Fix doc of
`set-window-buffer'.
* src/inotify.c (INOTIFY_DEFAULT_MASK): Removing ACCESS, OPEN
and CLOSE events on order do let other processes also reading
from their descriptors. (Bug#26973).
* src/nsterm.h [NS_IMPL_GNUSTEP]: Add typedefs for Cocoa-only types.
(NSWindowStyleMaskUtilityWindow): #define to NSUtilityWindowMask in
GNUstep and old versions of macOS.
* src/nsfns.m (ns-set-mouse-absolute-pixel-position): Function only
works in cocoa, not GNUstep.
Module functions were previously called "function environments" when
the functions created by module_make_functions were lambdas. Now we
can adapt the terminology and rename "function environments" to
"module functions" everywhere. This also removes the name clash
between "function environments" and "module environments."
* src/emacs-module.c (module_make_function): Adapt comment to reality;
stop using "function environment" terminology.
(funcall_module): Stop using "function environment" terminology.
* src/nsfns.m (Fns_list_services): Remove unreachable code. In this
branch NS_IMPL_COCOA cannot be defined.
(interpret_services_menu): Define only if called to avoid compiler
warnings about unused static functions.
* src/nsterm.m (mouseDown:):
* src/nsmenu.m (runMenuAt:forFrame:keymaps:): Remove call to
deprecated method. The return value is always nil.
* src/macfont.m (mac_font_shape_1): Replace call to deprecated method.
These semicolons are ignored and cause compiler warnings.
* src/nsimage.m (setPixelAtX:Y:toRed:green:blue:alpha:):
* src/nsterm.m (init, updateFrameSize:):
(setFrame:): Remove trailing semicolon.
This should not cause behavior changes, but fixes a compiler warning
due to implicit conversions between the enums.
* src/macfont.m (macfont_cache, macfont_lookup_cache)
(macfont_get_glyph_for_cid, macfont_get_uvs_table)
(macfont_variation_glyphs): Use NSCharacterCollection.
"%o" will display the percentage "travel" of the window through the buffer.
"%q" will display a combination of the percentage offsets of the top and
bottom of the window. The new user option mode-line-percent-position will
facilitate selecting a setting for this part of the mode line.
* lisp/bindings.el (mode-line-percent-position): New customizable user option.
(mode-line-position): Use mode-line-percent-position in place of "%p", etc.
* src/xdisp.c (decode_mode_spec): Add handlers for "%o" and "%q".
* doc/lispref/modes.texi (Mode Line Variables): Document
mode-line-percent-position.
(%-Constructs): Document %o and %q.
* etc/NEWS: Add an entry for these new facilities.
* src/print.c (print_vectorlike): New function, taken from
part of print_object. This one is indented properly, and
pacifies --enable-gcc-warnings by using a default case
instead of listing all the enum values, sometimes
incompletely.
(print_object): Use it.
It does not appear to be needed (Bug#24441).
* etc/PROBLEMS: Remove DARWIN_OS_CASE_SENSITIVE_FIXME stuff.
* src/fileio.c (file_name_case_insensitive_p):
Remove DARWIN_OS_CASE_SENSITIVE_FIXME code.
* etc/PROBLEMS: Document this (Bug#24441).
* src/fileio.c (file_name_case_insensitive_p): Prefer pathconf
with _PC_CASE_SENSITIVE, if it works, to
DARWIN_OS_CASE_SENSITIVE_FIXME code.
Support just one method for DARWIN_OS_CASE_SENSITIVE_FIXME,
which matches the Apple documentation more precisely.
* lisp/frame.el (ns-set-mouse-absolute-pixel-position): New
function (Lisp).
(set-mouse-absolute-pixel-position): Change it to call
`ns-set-mouse-absolute-pixel-position' on macOS.
* src/nsfns.m (Fns_set_mouse_absolute_pixel_position): New
function.
* src/nsterm.h (NS_PARENT_WINDOW_TOP_POS): Use the primary
screen's height as a base for calculating global coordinates.
* src/nsterm.m (frame_set_mouse_pixel_position): Fix it in macOS.
* test/lisp/mouse-tests.el (bug26816-mouse-frame-movement): Test
movement of mouse relative to frame.
* src/emacs-module.c (module_make_function):
Check that arities fit into fixnums, for func-arity’s benefit.
(funcall_module): Avoid unnecessary conversion to EMACS_INT.
(module_function_arity): Allow arities greater than SHRT_MAX.
Instead of a lambda, create a new type containing all data required to
call the function, and support it in the evaluator. Because this type
now also needs to store the function documentation, it is too big for
Lisp_Misc; use a pseudovector instead. That also has the nice benefit
that we don't have to add special support to the garbage collector.
Since the new type is user-visible, give it a predicate.
Now we can easily support 'help-function-args' and 'func-arity'; add
unit tests for these.
* src/lisp.h (allocate_module_function, MODULE_FUNCTIONP)
(XMODULE_FUNCTION): New pseudovector type 'module function'.
* src/eval.c (FUNCTIONP): Also treat module functions as functions.
(funcall_lambda, Ffuncall, eval_sub): Add support for calling module
functions.
(Ffunc_arity): Add support for detecting the arity of module
functions.
* src/emacs-module.c (module_make_function): Adapt to new structure.
Return module function object directly instead of wrapping it in a
lambda; remove FIXME.
(funcall_module): New function to call module functions. Replaces
`internal--module-call' and is called directly from eval.c.
(syms_of_module): Remove internal helper function, which is no longer
needed.
(module_function_arity): New helper function.
* src/data.c (Ftype_of): Adapt to new implementation.
(Fmodule_function_p, syms_of_data): New user-visible function. Now
that module functions are first-class objects, they deserve a
predicate. Define it even if not compiled with --enable-modules so
that Lisp code doesn't have to check for the function's existence.
* src/doc.c (Fdocumentation): Support module functions.
* src/print.c (print_object): Adapt to new implementation.
* src/alloc.c (mark_object): Specialized garbage collector support is
no longer needed.
* lisp/help.el (help-function-arglist): Support module functions.
While there, simplify the arity calculation by using `func-arity',
which does the right thing for all kinds of functions.
* test/data/emacs-module/mod-test.c: Amend docstring so we can test
the argument list.
* test/src/emacs-module-tests.el (mod-test-sum-docstring): Adapt to
new docstring.
(mod-test-non-local-exit-signal-test): Because `internal--module-call'
is gone, the backtrace has changed and no longer leaks the
implementation.
(module--func-arity): New test for `func-arity'.
(module--help-function-arglist): New test for `help-function-arglist'.
