I'm not aware of a TODO list. There are some in etc/TODO but I don't
think it's up to date.
One place to look is bug reports tagged "ns", but that is not an
exhaustive list of NS related bug reports (and some aren't really
anything to do with the NS port, they just happened to be spotted on a
Mac first).
M-x debbugs-gnu-usertags C-s ns <RET>
You'll notice a distinct lack of bug reports about missing features
since it appears nobody cares enough about, say, the missing tab bar
to raise a bug report.
Some of the problems with the NS port (like terrible thread support)
are, IMO, down to its architecture and require quite extensive work to
fix. I've started cleaning up the codebase in preparation for some
large fundamental changes, but I'm not convinced my plan is correct.
I'm not a professional developer, so my ideas about refactoring may be
questionable, and I haven't ever worked on any other *step code.
Additionally I'm not sure it's really a good idea for me to make these
large changes since then anyone who is already familiar with the
codebase will have to relearn it and I'm not sure they'll make it
easier to understand.
Have a look at scratch/ns/testing for some clean-ups to do with
colours.
If you want to improve the GNUstep experience I think the best place
to start would be improving nsfont. I've tried, but frankly I don't
understand fonts and my motivation ran out pretty quickly, especially
since some of the GNUstep side is completely undocumented.
Anyway, help with the NS port is always appreciated.

Thanks.

I did a best effort job at cleaning up nsfont and getting it into a
presentable state. I've also implemented some changes to the NS port in
general that implement some missing features (such as overhangs), and
fix some issues preventing nsfont from behaving correctly (namely the
horrid cursor drawing logic that I changed to behave closer to the
X-Windows code), and some changes to the menu logic.
There are still two problems with this code: the first being that if a
glyph with a left overhang is preceeded by a glyph with both a left and
a right overhang, the glyph with just the left overhang will be drawn
twice. I haven't been able to solve this problem, could someone please
take a look? Thanks.
The second problem is that, on startup, the toolbar is too tall unless
the frame is resized. I can't profess to understand the toolbar code
well enough to fix this problem.
As usual, it's completely untested on macOS. Could you (or someone with
access to a Mac) test it on macOS, see if there are problems with it
there, and if not, review and install these changes? Thanks.

This looks really good on GNUstep! I am no longer faced with a wide
selection of random fonts when I open xdisp.c!
A few wee things:
Except for the first line the commit message should be made up of full
sentences with full stops at the end.
I feel it might be good to split this into two separate patches, one
with the GNUstep stuff and the other with the changes to cursor
drawing, but that's up to you.
The cursor mostly doesn't draw under macOS, and when it does draw the
glyph is its normal colour instead of the inverted colours I see on
GNUstep and GTK. I had a quick look and can't see anything obviously
causing this. If you have no ideas I'll investigate further.
You missed a comment in ns_draw_window_cursor that refers to drawing
the text on top of the cursor.

I don't really understand this, but I'll have a look if I can.

This is not a new issue. I can't work out why it happens, but I think
it has to do with the frame resizing on startup.

Thanks, fixed.

The changes to cursor drawing are prerequisite to nsfont actually
behaving as expected, so I'd say no to this.
But there are some changes to the menu and modifier key code, to make
them work under GNUstep, and it might be prudent to split those changes.
WDYT?

I added an attempt to fix this, but it's totally untested.

Thanks for spotting this.

Basically, find any italic variable pitch font, and in it type
"ABSOLUTELY NO WARRANTY"
Then move the cursor over the "W" in "WARRANTY". A will appear to be
overstriked.
Thanks.

Subject: [PATCH] Improve rendering on NS port
* src/nsfns.m (Fx_create_frame): Use "fixed" for the default font on
GNUstep.
* src/nsfont.m (LCD_SMOOTHING_MARGIN, ns_escape_name)
(ns_unescape_name, ns_attribute_fvalue)
(STYLE_REF): Remove unused defines and functions.
(GS_FONT_SHAPE): Add option.
(struct ns_glyph_layout, enum lgstring_direction).
(enum gs_font_slant, enum gs_font_weight, enum gs_font_width)
(enum gs_specified, struct gs_font_data): New enumerators and
structures.
(ns_font_descs_match_p)
(ns_done_font_data, ns_get_font_data): New functions.
(ns_glyph_metrics): Stop escaping names.
(ns_spec_to_descriptor): Fix font descriptor creation for symbolic
font spec entires.
(ns_descriptor_to_entity): Create entries with the correct symbolic
styles.
(ns_fallback_entity): Fix fallback entity selection.
(ns_findfonts): Use our own font matcher instead of the broken GNUstep
matcher.
(ns_list_family): Remove obsolete comment.
(nsfont_open): Remove obsolete code, comments, and synthItal logic
which doesn't work on GNUstep.
(nsfont_encode_char): Use a type that can fit NSGlyph
(nsfont_draw): Chose correct font, remove obsolete mouse face logic,
obsolete comments, and switch to using glyph-based drawing instead of
character-based drawing.
(ns_font_shape, nsfont_shape): New functions.
(ns_uni_to_glyphs_1): New function.
(ns_uni_to_glyphs): Return glyphs instead of unicode codepoints.
(ns_glyph_metrics): Use NSGlyphs instead of unicode codepoints and fix
left bearing, right bearing, ascent and descent computation.
(struct nsfont_driver): Add shaping capability.
* src/nsterm.h (struct nsfont_info): Use unsigned int for glyph cache.
* src/nsterm.m (gsaved): Make integer.
(ns_focus, ns_unfocus): Set DPS clipping on GNUstep and always save GC.
(ns_redraw_scroll_bars): Enable on GNUstep.
(ns_compute_glyph_string_overhangs): Fix overhang computation by using
xterm code.
(ns_draw_window_cursor): Simplify cursor drawing.
(ns_maybe_dumpglyphs_background): Test for cursor HL and remove
obsolete mouse face logic.
(ns_dumpglyphs_image)
(ns_dumpglyphs_box_or_relief)
(ns_dumpglyphs_stretch): Rectify for new cursor logic.
(ns_draw_glyph_string_foreground): Remove mouse face logic.
(ns_draw_glyph_strings): Implement overhangs and remove obsolete
comment.
(ns_update_window_end): New function.
(ns_redisplay_interface): Add ns_update_window_end on GNUstep.
(ns_draw_text_decoration): Add condition for DRAW_CURSOR and simply
color selection.
(ns_define_frame_cursr): Remove nonsensical code (define_frame_cursor
has nothing to do with the text cursor, aka caret).
(- resizeWithOldSuperviewSize): Remove obsolete NSTRACE.
(ns_alternate_modifier, ns_command_modifier): Fix default value for
GNUstep.
* src/nsmenu.m (ns_update_menubar, - menuNeedsUpdate): Prevent
recursive calls.
* src/xdisp.c (draw_glyphs): Enable code for NS port to fix mouse face
cursor display.
* src/macfont.m (get_cgcolor_from_nscolor): New function.
(macfont_draw): Remove obsolete mouse-face code and enable cursor display.

I noticed that my previous attempt didn't resolve this problem.
Here is an updated patch that fixes this, and also fixes a few crashes
with the context menu. (Again, totally untested on macOS)

Subject: [PATCH] Improve rendering on NS port
* src/nsfns.m (Fx_create_frame): Use "fixed" for the default font on
GNUstep.
* src/nsfont.m (LCD_SMOOTHING_MARGIN, ns_escape_name)
(ns_unescape_name, ns_attribute_fvalue)
(STYLE_REF): Remove unused defines and functions.
(GS_FONT_SHAPE): Add option.
(struct ns_glyph_layout, enum lgstring_direction).
(enum gs_font_slant, enum gs_font_weight, enum gs_font_width)
(enum gs_specified, struct gs_font_data): New enumerators and
structures.
(ns_font_descs_match_p)
(ns_done_font_data, ns_get_font_data): New functions.
(ns_glyph_metrics): Stop escaping names.
(ns_spec_to_descriptor): Fix font descriptor creation for symbolic
font spec entires.
(ns_descriptor_to_entity): Create entries with the correct symbolic
styles.
(ns_fallback_entity): Fix fallback entity selection.
(ns_findfonts): Use our own font matcher instead of the broken GNUstep
matcher.
(ns_list_family): Remove obsolete comment.
(nsfont_open): Remove obsolete code, comments, and synthItal logic
which doesn't work on GNUstep.
(nsfont_encode_char): Use a type that can fit NSGlyph
(nsfont_draw): Chose correct font, remove obsolete mouse face logic,
obsolete comments, and switch to using glyph-based drawing instead of
character-based drawing.
(ns_font_shape, nsfont_shape): New functions.
(ns_uni_to_glyphs_1): New function.
(ns_uni_to_glyphs): Return glyphs instead of unicode codepoints.
(ns_glyph_metrics): Use NSGlyphs instead of unicode codepoints and fix
left bearing, right bearing, ascent and descent computation.
(struct nsfont_driver): Add shaping capability.
* src/nsterm.h (struct nsfont_info): Use unsigned int for glyph cache.
* src/nsterm.m (gsaved): Make integer.
(ns_focus, ns_unfocus): Set DPS clipping on GNUstep and always save GC.
(ns_redraw_scroll_bars): Enable on GNUstep.
(ns_compute_glyph_string_overhangs): Fix overhang computation by using
xterm code.
(ns_draw_window_cursor): Simplify cursor drawing.
(ns_maybe_dumpglyphs_background): Test for cursor HL and remove
obsolete mouse face logic.
(ns_dumpglyphs_image)
(ns_dumpglyphs_box_or_relief)
(ns_dumpglyphs_stretch): Rectify for new cursor logic.
(ns_draw_glyph_string_foreground): Remove mouse face logic.
(ns_draw_glyph_strings): Implement overhangs and remove obsolete
comment.
(ns_update_window_end): New function.
(ns_redisplay_interface): Add ns_update_window_end on GNUstep.
(ns_draw_text_decoration): Add condition for DRAW_CURSOR and simply
color selection.
(ns_define_frame_cursor): Remove nonsensical code (define_frame_cursor
has nothing to do with the text cursor, aka caret).
(- resizeWithOldSuperviewSize): Remove obsolete NSTRACE.
(ns_alternate_modifier, ns_command_modifier): Fix default value for
GNUstep.
* src/nsmenu.m (ns_update_menubar, - menuNeedsUpdate): Prevent
recursive calls.
(ns_menu_show): Fix context menu crash.
* src/xdisp.c (draw_glyphs): Enable code for NS port to fix mouse face
cursor display.
* src/macfont.m (get_cgcolor_from_nscolor): New function.
(macfont_draw): Remove obsolete mouse-face code and enable cursor display.

And here's a new patch with some other problems fixed (such as broken
mouse face display, tab bar grab reporting and some crashes in nsmenu).
And hopefully a working though ugly solution for fixing the tool bar
height on GNUstep. Thanks.

Subject: [PATCH] Improve rendering on NS port
* src/nsfns.m (Fx_create_frame): Use "fixed" for the default font on
GNUstep.
* src/nsfont.m (LCD_SMOOTHING_MARGIN, ns_escape_name)
(ns_unescape_name, ns_attribute_fvalue)
(STYLE_REF): Remove unused defines and functions.
(GS_FONT_SHAPE): Add option.
(struct ns_glyph_layout, enum lgstring_direction).
(enum gs_font_slant, enum gs_font_weight, enum gs_font_width)
(enum gs_specified, struct gs_font_data): New enumerators and
structures.
(ns_font_descs_match_p)
(ns_done_font_data, ns_get_font_data): New functions.
(ns_glyph_metrics): Stop escaping names.
(ns_spec_to_descriptor): Fix font descriptor creation for symbolic
font spec entires.
(ns_descriptor_to_entity): Create entries with the correct symbolic
styles.
(ns_fallback_entity): Fix fallback entity selection.
(ns_findfonts): Use our own font matcher instead of the broken GNUstep
matcher.
(ns_list_family): Remove obsolete comment.
(nsfont_open): Remove obsolete code, comments, and synthItal logic
which doesn't work on GNUstep.
(nsfont_encode_char): Use a type that can fit NSGlyph
(nsfont_draw): Chose correct font, remove obsolete mouse face logic,
obsolete comments, and switch to using glyph-based drawing instead of
character-based drawing.
(ns_font_shape, nsfont_shape): New functions.
(ns_uni_to_glyphs_1): New function.
(ns_uni_to_glyphs): Return glyphs instead of unicode codepoints.
(ns_glyph_metrics): Use NSGlyphs instead of unicode codepoints and fix
left bearing, right bearing, ascent and descent computation.
(struct nsfont_driver): Add shaping capability.
* src/nsterm.h (struct nsfont_info): Use unsigned int for glyph cache.
(struct ns_output_data): New field for tracking tool-bar updates.
* src/nsterm.m (gsaved): Make integer.
(ns_focus, ns_unfocus): Set DPS clipping on GNUstep and always save GC.
(ns_redraw_scroll_bars): Enable on GNUstep.
(ns_compute_glyph_string_overhangs): Fix overhang computation by using
xterm code.
(ns_draw_window_cursor): Simplify cursor drawing.
(ns_maybe_dumpglyphs_background): Test for cursor HL and remove
obsolete mouse face logic.
(ns_dumpglyphs_image)
(ns_dumpglyphs_box_or_relief)
(ns_dumpglyphs_stretch): Rectify for new cursor logic.
(ns_draw_glyph_string_foreground): Remove mouse face logic.
(ns_draw_glyph_strings): Implement overhangs and remove obsolete
comment.
(ns_update_window_end): New function.
(ns_redisplay_interface): Add ns_update_window_end on GNUstep.
(ns_draw_text_decoration): Add condition for DRAW_CURSOR and simply
color selection.
(ns_define_frame_cursor): Remove nonsensical code (define_frame_cursor
has nothing to do with the text cursor, aka caret).
(mouseDown): Enable grab tracking.
(- resizeWithOldSuperviewSize): Remove obsolete NSTRACE.
(ns_alternate_modifier, ns_command_modifier): Fix default value for
GNUstep.
* src/nsmenu.m (ns_update_menubar, - menuNeedsUpdate): Prevent
recursive calls.
(ns_menu_show): Fix context menu crash and work around mysterious bug.
(update_frame_tool_bar_1): Work around toolbar sizing bug.
* src/xdisp.c (draw_glyphs): Enable code for NS port to fix mouse face
cursor display.
* src/macfont.m (get_cgcolor_from_nscolor): New function.
(macfont_draw): Remove obsolete mouse-face code and enable cursor
display.
* src/frame.c (gui_mouse_grabbed, gui_redo_mouse_highlight): Enable on
NS port.
* src/xdisp.c (note_tab_bar_highlight): Drop conditional around NS code.

Can I ask why you're saving the context every time ns_focus is called?
It shouldn't be necessary unless we're making a change, like calling
NSRectClip. Any deeper functions that make changes save and restore
the context locally.

I don't think these changes are right:
By default, GNUstep uses Control_L (left Ctrl) and Control_R (right
Ctrl) as CONTROL, Alt_L (left alt) as COMMAND, and Alt_R (right alt,
sometimes called AltGr) as ALTERNATE. As a special exception, if Alt_R
is not bound to any key on your keyboard, GNUstep will try to use
Mode_switch for ALTERNATE instead. Some X server map AltGr onto
ISO_Level3_Shift. To allow for this the second code ALTERNATE may be
bound to this key.
http://www.gnustep.org/resources/documentation/User/Gui/KeyboardSetup.html
We have command bound to super so the default Openstep shortcuts work,
like cmd-q to quit, and alt bound to meta, because that's pretty
standard in Emacs.
Now, it seems to me that right alt does NOT work as alt under
GNUstep, but instead still acts as normal altGr, but I don't think
that's anything to do with how we bind it in Emacs.
And weirdly the windows key is bound to Hyper by default... I kind of
suspect the GNUstep standards for keyboards are quite out of date, but
we should probably try to stick to them.

Will do, thanks. But it would be easier for me if you could review the
big patch first, and if it's all fine, I'll split it up.

That makes it easier to nest ns_focus. (Unless that's a bad idea, I
think it should work.)

Yes, on GNUstep DPS functions don't respect clipping set through NSRectClip.

I think the entire comment is not accurate anymore; the precise
behaviour of redisplay seems to have changed. But I'm not sure.

What do you mean by "alt" here? If it means the "alt" key on the user's
keyboard, then I think setting ns_command_modifier to meta is TRT,
because on most systems that will be the left alt key.
Thanks.

Well, I haven't gone over the changes in nsfont.m in detail because I
don't really understand what any of that code does, but aside from
that and the issues I've already raised I don't see anything of concern.

Is there any reason to nest ns_focus? There are (according to Apple)
performance reasons to not save the context unless you really need to.

I mean alt as defined by GNUstep in the quote I sent you in my last
email. I don't think it's our job to say that GNUstep's choice of
defaults is wrong and therefore do something that would be unexpected
for a GNUstep user.

Right now it's used in the code that clips to the exact bounds of a
string, if a string's overhangs are already drawn.
I couldn't find a cleaner way to do this, and that situation is rare, so
I think the performance problems will usually be avoided.

Well, on every other platform Meta is on the alt on the users' keyboard.
Emacs in general doesn't conform to the platform expectations WRT to key
bindings, so I think being consistent with Emacs on other platforms is
more important here.
But in the end, it's your call. Thanks.

Thanks, applied.
I'll split the patch up and let you know.

Subject: [PATCH 1/2] Improve font display on NS port
* src/nsfns.m (Fx_create_frame): Use "fixed" for the default font on
GNUstep.
* src/nsfont.m (LCD_SMOOTHING_MARGIN, ns_escape_name)
(ns_unescape_name, ns_attribute_fvalue)
(STYLE_REF): Remove unused defines and functions.
(struct ns_glyph_layout, enum lgstring_direction).
(enum gs_font_slant, enum gs_font_weight, enum gs_font_width)
(enum gs_specified, struct gs_font_data): New enumerators and
structures.
(ns_font_descs_match_p)
(ns_done_font_data, ns_get_font_data): New functions.
(ns_glyph_metrics): Stop escaping names.
(ns_spec_to_descriptor): Fix font descriptor creation for symbolic
font spec entires.
(ns_descriptor_to_entity): Create entries with the correct symbolic
styles.
(ns_fallback_entity): Fix fallback entity selection.
(ns_findfonts): Use our own font matcher instead of the broken GNUstep
matcher.
(ns_list_family): Remove obsolete comment.
(nsfont_open): Remove obsolete code, comments, and synthItal logic
which doesn't work on GNUstep.
(nsfont_encode_char): Use a type that can fit NSGlyph
(nsfont_draw): Chose correct font, remove obsolete mouse face logic,
obsolete comments, and switch to using glyph-based drawing instead of
character-based drawing.
(ns_font_shape, nsfont_shape): New functions.
(ns_uni_to_glyphs_1): New function.
(ns_uni_to_glyphs): Return glyphs instead of unicode codepoints.
(ns_glyph_metrics): Use NSGlyphs instead of unicode codepoints and fix
left bearing, right bearing, ascent and descent computation.
(struct nsfont_driver): Add shaping capability.
* src/nsterm.h (struct nsfont_info): Use unsigned int for glyph cache.
* src/nsterm.m (gsaved): Make integer.
(ns_focus, ns_unfocus): Set DPS clipping on GNUstep and always save GC.
(ns_compute_glyph_string_overhangs): Fix overhang computation by using
xterm code.
(ns_draw_window_cursor): Simplify cursor drawing.
(ns_maybe_dumpglyphs_background): Test for cursor HL and remove
obsolete mouse face logic.
(ns_dumpglyphs_image)
(ns_dumpglyphs_box_or_relief)
(ns_dumpglyphs_stretch): Rectify for new cursor logic.
(ns_draw_glyph_string_foreground): Remove mouse face logic.
(ns_draw_glyph_strings): Implement overhangs and remove obsolete
comment.
(ns_draw_text_decoration): Add condition for DRAW_CURSOR and simplify
color selection.
(ns_define_frame_cursor): Remove nonsensical code (define_frame_cursor
has nothing to do with the text cursor, aka caret).
* src/xdisp.c (draw_glyphs): Enable code for NS port to fix mouse face
cursor display.
* src/macfont.m (get_cgcolor_from_nscolor): New function.
(macfont_draw): Remove obsolete mouse-face code and enable cursor
display.

(update_frame_tool_bar_1): Work around mysterious toolbar sizing bug
on GNUstep.
* src/nsterm.h (struct ns_output): New field for tracking toolbar
visibility changes.
* src/nsterm.m (frame_set_mouse_pixel_position): Implement for
GNUstep.
(ns_redraw_scroll_bars): Enable for GNUstep.
(ns_clear_frame): Redraw scrollbars on GNUstep.
(ns_update_window_end): New function.
(ns_redisplay_interface): Add ns_update_window_end on GNUstep.
(- keyDown): Remove debug code that doesn't work on GNUstep.
(- mouseDown): Enable grab tracking on NS port.

I'm not sure if this is related to what you're talking about because I
don't see any connection with frame (re)size, but I've just reported
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=51361 concerning the
toolbar size.
Best regards,
Carlos

This is an unrelated issue that only appears on GNUstep. But I've found
a workaround, which I've sent Alan for review (along with the rest of
the improvements scattered around).
Hopefully, he can review and install the changes ASAP, but one question
about modifier keys has to be clarified first.
Thanks.
