Fix regression due to change in face sort order by 'face-list'

2023-02-18T07:37:34+00:00

* lisp/faces.el (x-create-frame-with-faces): Undo reversing of
the face list, which is no longer necessary, since 'face-list's
sorting order has been reversed recently.  (Bug#61521)

Fix order of faces in 'face-list'

2023-02-17T08:27:39+00:00

* lisp/faces.el (frame-face-alist, face-list): Sort faces in
decreasing order of face IDs.  Patch by Brennan Vincent
.  (Bug#61521)

Avoid spurious pause in kill-ring-save (Bug#60841)

2023-02-02T18:39:39+00:00

'indicate-copied-region' checks whether the region is "highlighted"
and if not, briefly moves point to mark to give a visual cue of the
extent of text that was saved to the kill ring.

The region is considered "highlighted" if (a) it is active and (b) its
face specifies a :background.  That latter condition does not account
for the multiple ways in which the face can make the region "visually
distinct" from the default face, so switch to the more extensive
predicate face-differs-from-default-p.

The patch also fixes a couple of issues with the predicate's
implementation, and introduces a new user option in case anyone
happened to enjoy unconditional blinking.

* lisp/faces.el (face-differs-from-default-p): Filter out :extend; add
rationale for the attributes we ignore.
* lisp/simple.el (copy-region-blink-predicate): Add option to let
users explicitly opt into or out of blinking point and mark.
(region-indistinguishable-p): New function to detect
"if there is currently no active region highlighting", leveraging
face-differs-from-default-p.
(indicate-copied-region): Use it.
* src/xfaces.c (merge_face_ref): Allow :stipple to be nil, since it is
a documented valid value for that attribute.
* etc/NEWS: Announce user option.

; Fix recently modified docs of 'set-face-attribute' (bug#52493)

2022-12-30T14:43:38+00:00

* doc/lispref/display.texi (Attribute Functions): Clarify wording
and restore removed information about resetting attributes to
'unspecified' for future frames.

* lisp/faces.el (set-face-attribute): Minor copyedit of doc
string.

Clarify the documentation of 'set-face-attribute'

2022-12-29T22:43:34+00:00

* lisp/faces.el (set-face-attribute): Mention the evaluation order
of attribute-value pairs in the docstring.

* doc/lispref/display.texi (Attribute Functions): Likewise, and
explain with an example that a different argument order might give
different results.  Also align the documentation in the manual
with that of the docstring, whose changes were discussed in
bug#57499 but not included in the manual.

Make the Contour terminal an alias of xterm-256color

2022-12-24T07:50:51+00:00

* lisp/faces.el (term-file-aliases): Make the Contour terminal an
alias of xterm-256color.  (Bug#60278)

Fix automatic DPI adjustment and add workarounds for some systems

2022-11-19T05:59:53+00:00

* lisp/faces.el (x-create-frame-with-faces): New field
`delayed-font'.  Set the `font-parameter' property to `font' in
the given parameter list after face-set-after-frame-default is
called.
* src/fontset.c (Fset_fontset_font): Avoid changing
`font-parameter' with the call to Fmodify_frame_parameters.
* src/frame.c (gui_set_frame_parameters_1): New function.
Factor out gui_set_frame_parameters here, and add an argument
DEFAULT_PARAMETER.  If the `font' parameter is set, and
`default_parameter' is not, then set the `font-parameter' frame
parameter to the `font' parameter as well, to keep track of
which user-specified `font' frame parameter set the default
face's font on the frame.
(gui_set_frame_parameters): Call gui_set_frame_parameters_1 with
new arg set to false.
(gui_set_font): Remove broken implementation of
`font-parameter'.
(gui_default_parameter): If the default value was used, then
call gui_set_frame_parameters_1 with the new argument set to
false.  This is because no font was specified as a frame
parameter by the user, so Freconsider_frame_fonts is free to do
anything it wants.
(Freconsider_frame_fonts): If `font-parameter' is set, then use
it.
(syms_of_frame): New defsym Qfont_parameter.

* src/frame.h: Update prototypes.

* src/haikuterm.c (haiku_default_font_parameter):
* src/pgtkfns.c (pgtk_default_font_parameter):
* src/w32fns.c (w32_default_font_parameter): Stop setting
`font-parameter' here.  This code resulted in decades of
automatic font rescaling not working correctly.

* src/xfaces.c (set_font_frame_param): Clear the
`font-parameter' frame parameter.
(Finternal_merge_in_global_face):
* src/xfns.c (x_default_font_parameter): Avoid changing
`font-parameter' in response to changes to face attributes.
* src/xsettings.c (apply_xft_settings): Add workaround for
Cairo.  (bug#59371, bug#59347, bug#59283, bug#59271, bug#59285,
bug#59306.)

Add flat-button to docstring of 'set-face-attribute'

2022-11-16T14:43:05+00:00

* lisp/faces.el (set-face-attribute): Add 'flat-button' to
COLOR and STYLE sections of docstring.  (Bug#59266)
