* bug#51411: NS port cleanups [not found] <87mtmwt3mc.fsf.ref@yahoo.com> @ 2021-10-26 11:41 ` Po Lu via Bug reports for GNU Emacs, the Swiss army knife of text editors 2021-10-26 12:39 ` Alan Third 0 siblings, 1 reply; 22+ messages in thread From: Po Lu via Bug reports for GNU Emacs, the Swiss army knife of text editors @ 2021-10-26 11:41 UTC (permalink / raw) To: 51411 [-- Attachment #1: Type: text/plain, Size: 1368 bytes --] I did not notice that the thread previously titled "NS port improvements" was moved off bug#51251 onto emacs-devel, but now that there are concrete changes I think it would be a good opportunity to post them on bug-gnu-emacs, per the CONTRIBUTE document. The changes, with the generic improvements split from the changes to font rendering are attached. Alan raised several questions, which I answered. I've reproduced that part of the discussion below: > 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. 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. > 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. 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.

That function is a real mess of calls to ns_focus and ns_unfocus. I think there's no good reason for them to be called as often as they are, and some related functions (ns_dumpglyphs_stretch) don't need to call them themselves either. I think we need to have a rethink of how clipping is handled here. We don't need to use ns_focus to clip and we repeatedly call ns_focus on the same rectangle. For a lot of those calls we could replace them with a single clipping rectangle and adjust it as required for overhangs or whatever. I also think you misunderstood what I was saying about the performance problems with calling saveGraphicsState. Calling it when not required is frowned upon by Apple as they say it causes performance problems. Your code is now calling it in ns_focus whether it's required or not. Ideally we only call it when modifying the clipping rectangle, because there are times ns_focus is called where we don't modify the clipping rectangle and therefore we don't need to save the graphics context. I understand what you did, but I think the better solution is for us is to try to untangle ns_draw_glyph_string, even if that means saving the context there directly on occasion. If you want me to have a look at it let me know, I think I know what needs to be done, but I probably won't get round to it as soon as you could. -- Alan Third ^ permalink raw reply [flat|nested] 22+ messages in thread

Thanks. I had a try at it, cleaning up much of what appeared obviously unnecessary. (Though I did not dare change what seemed to be mysterious to me.) Though, OTOH, I think calling saveGraphicsState inside the overhang draw process is not too much of a problem as it happens infrequently enough to not be relevant.

(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.

(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.c (ns_focus): Set DPS clipping 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): Rectify for new cursor logic. (ns_dumpglyphs_stretch): Rectify for new cursor logic and rely on ns_draw_glyph_string to set focus. (ns_draw_glyph_string_foreground): Remove mouse face logic. (ns_draw_glyph_strings): Implement overhangs, remove obsolete comment, and always focus before dumping glyphs. (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.

I must be failing to communicate well, we keep seeming to misunderstand each other. You still need to focus, however you don't have to clip when you focus. For example you could do something like: ns_focus (f, nil, 0); [[NSGraphicsContext currentContext] saveGraphicsState]; NSClipRect (r1); // do something [[NSGraphicsContext currentContext] restoreGraphicsState] [[NSGraphicsContext currentContext] saveGraphicsState]; NSClipRect (r2); // do something else [[NSGraphicsContext currentContext] restoreGraphicsState] ns_unfocus (f); The only time you don't need to focus is when you can guarantee the calling function (or its caller, etc.) has already focused the view. -- Alan Third ^ permalink raw reply [flat|nested] 22+ messages in thread

It could be my problem as well: my reading comprehension is nowhere near as good as I would rather it be. Thanks a lot for tolerating it. > You still need to focus, however you don't have to clip when you > focus. After I unfocus here: /* Draw box if not done already. */ if (!s->for_overlaps && !box_drawn_p && s->face->box != FACE_NO_BOX) ns_dumpglyphs_box_or_relief (s); -> ns_unfocus (s->f); I make sure to focus again if an overhang might be drawn again (inside if (s->prev) and if (s->next)), like so: /* Draw surrounding overhangs. */ if (s->prev) { -> ns_focus (s->f, NULL, 0); struct glyph_string *prev; There is, of course, a matching unfocus.

I noticed that you removed all calls to ns_focus in ns_draw_window_cursor and thought you'd removed all calls to ns_focus, but now I see that's an older change. Is that a good idea?

Some drawing functions are definitely used outside ns_update_begin/end, at least in the NS port. Could you please put ns_focus calls back into ns_draw_window_cursor, just in case they are needed, and we can get these changes put into master and then maybe look at whether we need all these ns_focus calls as a separate task (it would certainly be nice if we could get rid of a few of them!). -- Alan Third ^ permalink raw reply [flat|nested] 22+ messages in thread

(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.
